    Perform a visual and ‘smell check’ inspection of the fueling components to see if there are any leaks, fumes, or signs of potential fuel leaks present. This includes fuel odors as well signifying there may be a fuel leak or at a minimum fuel vapors present. Tank, fuel nozzle, fuel swivel, fuel hose, fuel pump, and surrounding areas should be inspected at a minimum. If any of the above present, dry the location accordingly and wait no less than 1 hour to reinspect. Repeat this process until there is no fuel presence then continue on with these steps. Please see the “Troubleshooting” and “Repairs” section of the owner’s manual for assistance.

    3- Battery Check

    Ensure there is adequate battery life to complete the desired operation. You can reference the charge light indicator on the charger brick. If the light is Green then the Product is considered fully charged. If yellow, the product is adequately charged for a typical use case, though you should consider fully charging the product before heavy usage. If the charge indicator is red, then it is not done charging and it is advised to wait until it is green before operating. For added reassurance of adequate battery life, check for the green light on the thumb throttle to be illuminated after a fresh charge

    4- Brake System Check:

    Confirm the brakes have adequate pressure by compressing the lever a few times, feeling for resistance and pressure in the brake system (lever action should be stiff). Release the parking brake ensuring the Product is free to roll. See Figure 13.

    Smart Ass Fuel Mule Gas Caddy front end view with spindles, tie rods, and locking pin

    Figure 13





    If there is little to no pressure in the brake system, do not operate the product until brake system is corrected and pressure is present. Please refer to the “Troubleshooting” or “Repairs” section of the User Manual to learn how to troubleshoot this issue.

    5- Controls Check

    Observe the function of the Product’s physical controls by taking the steering arm (while powered off) and turning the arm side to side as well as up and down. Make sure there is free range of motion with no outside or system components causing any interference. If there is an observed controls issue, do not operate the Product until the controls issue is resolved. Please refer to the “Repairs” and “Troubleshooting” section of the User Manual for assistance.

    6- System Power

    With the previous check complete, ensure the Product is unplugged from the charger and ready to use. Go ahead and power on the key switch by switching into Drive (key switch counterclockwise).

    Smart Ass Fuel Mule Gas Caddy with Pump - Loading Procedure

    Follow these instructions outlined below for the best and safest operation of your Smart Ass Fuel Mule Motorized Gas Caddy with Pump when loading the Product.

    1- Loading Area Inspection

    When beginning the loading procedure, first inspect the loading area to ensure it is open, free of objects, and conditions are dry with adequate floor/ground traction for the tires to have good and proper grip. Confirm the transportation vehicle that the Product is being loaded into is stationary and in a parked state with all proper parking brakes or parking measures applied.

    2- Ramp Setup

    If using ramps into a pickup truck, ensure the ramps meet the requirements. Ramps must be a minimum of 1,000lb rated total, which is 500lb per ramp. The operator must also ensure that the operator’s weight added to half the Product weight (full can be up to nearly 570lbs, half of this is 285lbs) does not surpass the weight limit of the ramps. For instance, If the Operator is 250lbs and the half product weight is 285lbs, the 500lb ramp will no longer work. Since the operator will be walking on one ramp while unloading and the total weight on one ramp will be 535Lb, 35lbs over the limit.

    Place the ramps on the truck loading platform according to the ramp manufacturers specs. Additionally, operators should use straps to fasten the ramps to the truck to firmly press the ramps up against the truck platform to prevent movement during operation. See Figure 17.

    When loading your Smart Ass Fuel Mule Gas Caddy into a truck, always strap the ramps to the truck

    Figure 17





    With the ramps strapped down and in place, confirm the wheel spacing is equal to the wheel base of the Fuel Caddy. The width from the center of the left wheel to the center of the right wheel is 27” inches. Using a tape measure, confirm that the ramp spacing is 27” inches center to center of the ramps at both the top and bottom of the ramps. See Figure 18.

    When loading your Smart Ass Fuel Mule Gas Caddy into a truck, always space the ramps 27 inches center-to-center to match the wheel width

    Figure 18





    The slope of the ramps when set up on the pickup truck must not exceed 22° when transporting gasoline or AVGAS. This maximum slope angle is 20° with diesel, biodiesel, kerosene, or Jet A due to the increased weight when full. One of many ways you can check what angle you are at is with a simple level finder app for your smartphone. The iPhone App Store has a simple app called ‘Level’.

    If the incline of the ramps you are using is greater than the allowable angle, you have two options. See Figure 19 and 19a.

    · Use longer ramps to reduce the incline – the longer the ramps, the lower the angle. See Figure 19a.

    · Reduce the elevation change between the truck/trailer bed and ground using a hill or high spot. With the truck parked on flat ground, but backed up to a higher spot, perhaps a small hill in the yard, you can use this to reduce the angle of the ramps.

    When loading your Smart Ass Fuel Mule Gas Caddy into a truck, do not exceed 20 to 22 degrees ramp angle depending on fuel type as described in this manual

    Figure 19





    You can use this chart to determine the length of ramp you will need to achieve an acceptable slope angle for loading/unloading of your Smart Ass Fuel Mule Gas Caddy.

    Figure 19a





    If you have a very tall truck, or your ramps are a little short, you can use a hill to solve your problem in some cases. With the truck on flat ground, and the ramps resting on a higher point due to an available hill you can make use of, you can dramatically decrease the slope of the ramps into your truck.

    3- Controls Test

    With the ramps setup and ready for use, confirm the driving functions of your Motorized Fuel Caddy before proceeding. Key on the Product by switching the Key Switch to drive (counterclockwise). Ensure you are heading in the proper direction by checking the reverse toggle button for forward direction (apply brakes, use light throttle to test direction, reverse if necessary). While test driving the Product, ensure there is adequate brake pressure and confirm the Product stops when applying the brakes and that there is adequate pressure. Check that the Emergency Stop works by operating the throttle and testing the Emergency Stop thus stopping the Product from driving. Confirm that the steering is indeed tight and turning the wheels as desired.

    4- Product Loading Procedure

    With the controls check completed, begin by lining up with Product with the ramps. Confirm there are no bystanders in the backward direction of the product if it were to roll back. This is to avoid any bystander from being impacted or crushed in the instance of a loss of control or roll away. The operator must stay in front of the product and be positioned to walk up the ramps first.

    *Never operate the Product while the operator or a bystander are downhill or down ramp of the product as a component failure or misuse of the product may result in a sudden loss of control of the Product. This can lead to the Product rolling down the ramps potentially crushing the operator or bystander.*

    With both of the operator’s hands on the handle, one hand controlling the throttle and the other controlling the brake, the operator may begin to slowly walk backwards up the ramps watching their footing the entire way up. The operator should be ready to brake at any moment if need be (always be ready on the brake). Modulating the throttle the whole way up the ramps maintaining a safe speed. Once up the ramps, the operator then uses the brakes to bring the product to a stop in the desired parking location for transporting.

    *If at any moment the operator stumbles, loses footing, or misses a step and begins falling, it is advised that the operator let go of the Product and attempt to orient themselves away from the product. This will help to prevent being crushed or pulled and dragged with the Product. Because there are no bystanders in the backwards direction of the Product, the risk of sever injury(such as crushing) due to a falling on ramps should be significantly reduced.*

    5- Securing the Product

    With the parking brake applied and the key switch powered off, the operator can now place the steering arm lock pin to prevent the arm from moving during transportation. This will lock the steering arm vertically. See Figure 20.

    Smart Ass Fuel Mule Gas Caddy with pump - steering arm locking pin for transport

    Figure 20





    With the parking brake on and the steering arm locking pin set for transport, the ratches straps can now be applied. Strap the product from all four corners of the Product to the transporting vehicle or trailer. There is a tow strap cutout in the rear to secure the product. For strapping in the front, it is advised to strap around the uprights on the front of the Chassis. IMPORTANT! This locking pin is intended to secure the arm when your Smart Ass Fuel Mule Gas Caddy is in transit. Never pull on the steering arm without removing this pin, or pin may bend and become difficult to use. See Figure 21.

    Smart Ass Fuel Mule Gas Caddy with pump - front hooks for straps during transport

    Figure 21





    For strapping down the rear of the Product, it is advised to strap to the existing strap hole provisions cutout in the motor plate. See Figure 22.

    Figure 22





    Smart Ass Fuel Mule Gas Caddy with Pump - Unloading Procedure

    Follow these instructions outlined below for the safest operation and performance of the Product when unloading. Steps 1 and 2 are the same as steps 1 and 2 of the “Loading Procedure”. Please refer back to the Loading Procedure section above for steps 1 and 2. Once steps 1 and 2 are complete, move on to step 3 below.

    3- Unstrapping the Product

    With the ramps in place and ready for unloading, the operator can now unstrap the Product. After removing all straps, the operator can remove the Locking Pin and free the Steering Arm for movement and placing the pin in the storage hole on the bottom of the Steering Arm Base.

    4- Controls Test

    When unloading the Product, it is crucial the controls operate properly. To ensure that the controls work, make sure that the parking brake is off and no longer applied. Begin by applying the brakes and feeling for brake pressure. With adequate brake pressure confirmed, begin turning the steering arm side to side while keeping the product in place to ensure steering is correct and fully functional. With your hand ready to kill the power on the Emergency Stop, key on the powertrain by turning the key switch counter clockwise. Once the powertrain is on, ensure the Product reverse button is toggled. With your hands ready on the brakes, apply a small amount of throttle to ensure the direction is correct and towards the unloading direction and not forward in the direction of the operator.

    5- Product Unloading

    With the controls check completed, begin by lining up with Product with the ramps making sure to look for both wheels to be lined up to the center of each ramp. Confirm there are no bystanders in the backward direction of the product if it were to roll back. This will avoid any bystander from being impacted or crushed in the instance of a loss of control. It is good practice to have a bystander standing beside the tow vehicle and ramps that is positioned perpendicular to the unloading path. The bystander can help advise the operator if the wheels are indeed lined up with the ramps at all times. The operator must stay uphill of the product and be walking the product down the ramps slowly with their hands on the brakes actively modulating speed the whole time. With the rear wheels on the ramps, gravity begins to pull the Product down the ramps without the need of the throttle. During this time the operator is primarily modulating the brakes, and allowing the product to roll down safely at a very slow speed. The operator should be walking step by step very slowly down one ramp for best handling and footing. Once the rear wheels reach ground level at the bottom of the ramps, the operator may begin to use throttle again to fully drive the Product off the ramps. The operator should continue to watch their footing as they operate the product completely off the ramps onto level ground.

    *Never operate the Product while the operator or a bystander are downhill of the product as a component failure or operator misuse may result in a sudden loss of control of the Product and it may begin to roll down the ramps potentially crushing the operator or bystander in the Products path.*





    Smart Ass Fuel Mule Gas Caddy - Charging procedure

    1- Charging Location

    Locate an open and well-ventilated area where the Product can be parked on level ground that is dry and out of the weather’s elements. Verify there are no open flames, ignition sources, spark sources, and or heat sources in the area at any time. The location should also have access to a standard 110V wall outlet for power.

    2- Setup

    Ensure that the Product key switch is off and the Emergency Stop is enabled causing all systems to be powered down. Once power is off, apply the parking brake. Make sure all tank ingress points (fuel fill neck, fuel nozzle spout, and fuel pump bung) are closed and properly sealed. Inspect all fuel components and surrounding areas to verify there are no fuel leaks, fuel puddles, fuel condensation, or fuel vapors present. This includes confirming there is no gas smell present. If any of the above present, dry the location accordingly and wait no less than 1 hour to reinspect. Repeat this process until there is no fuel presence then continue on with these steps.

    3- Plugging in to Charge

    First start by removing the dust cover on the charging port on your Smart Ass Fuel Mule Gas Caddy (on the side of the battery box) and plug the charger in until you hear a click and see that the charger is locked in place. Next ensure that the power cord, this plugs in the brick on one end and into the Product on the other, is firmly plugged into the charging brick. Once confirmed, plug in the charger to a 110V wall outlet. The indication light on the charging brick should light up red indication that the battery is low and that Product is now charging.

    4- Charging Duration

    The full charge time can be approximately 12 hours depending on how low the battery capacity is upon plug in. It is best to judge accordingly and adjust how many hours you charge based on the presumed battery life left. See Figure 23.

After ensuring the area is free from any potential vapor and fumes and waiting the necessary time if needed, remove the charging connector from the battery box by pushing the tab on top of the connector to release the connector and pull it out from the battery box. From here the Product is now ready to operate.





    Smart Ass Fuel Mule Gas Caddy - Filling Procedure

    For safe and efficient operation when working with any part of the fueling system, it is imperative to adhere to the following safety procedures diligently.

    1- Initial Inspection

    With the Product powered off, observe any signs of leaks in the fuel system whether it is puddling, dripping, fuel buildup, wet fuel connections, or strong fuel smell indicating a possible fuel leak presence. If any of the above present, dry the location accordingly and wait no less than 1 hour to reinspect. Repeat this process until there is no fuel presence then continue on with these steps. Please refer to the “Troubleshooting” section for assistance.

    2- Tank Contents Check

    Verify the fuel level and fuel type currently in the Product, this will help ensure the operator of how much of a specific fuel is present and what level of caution to use when filling and dispensing. This will also help avoid cross contamination if the Product is used with more than one fuel.

    3- Neutralizing Static Electricity Risk

    When preparing to fill fuel into the Product, it is critical to handle the different electrical potentials with care. To do this when filling your Smart Ass Fuel Mule Gas Caddy with a commercial pump, you will grab the fuel nozzle of the gas station pump that will be dispensing fuel into the product. While grabbing the nozzle and ensuring you are touching metal on the nozzle, you can then use the other free hand to touch the conductive metal away from the fill neck of the Transfer Tank. Grabbing both elements with your bare hands will neutralize the electrical potential between the two systems. Once neutralized, you can now remove the fill cap and insert the nozzle into the Product. From here, the antistatic grounding wire built into the commercial fuel pump will continue neutralizing the potential of the separate systems through the metal nozzle contacting the metal fill neck of the Product. Essentially bonding them together. See figure 24.

    Smart Ass Fuel Mule Gas Caddy with pump - nuetralizing static electricity risk

    Figure 24





    4- Filling the Product

    When ready to fill the product with fuel, there is a necessary airgap to maintain inside your Gas Caddies tank to prevent overfilling. The bottom of the fill neck measures out the maximum level fuel allowed in the product and should never be surpassed. This airgap is necessary for fuel expansion which commonly occurs in hot environments where the tank may begin to build pressure, heat up, and cause fuel expansion or even overflow out of the fuel cap if this airgap is not maintained. Do not fill above this level. See Figure 25.

    Smart Ass Fuel Mule Gas Caddy with pump maximum fuel fill level to allow for expansion

    Figure 25





    5- Once Filling is Complete

    Once the Product filling is complete, return the commercial pump nozzle to the station, install the fill cap, and ensure the cap is secured and there are no visual leaks present.





    Smart Ass Fuel Mule Gas Caddy - Fuel Dispensing Procedure

    Ensuring safety during fuel dispensing procedures is paramount and must be exercised with caution at all times.

    1- Surroundings Check

    An inspection of the fueling area must be done before powering on the Product. Check the surroundings for any open flames, spark, heat sources, no lit cigars/cigarettes, or spark potential. If any existing or potential ignition source is observed, do not proceed fueling until the area is free and clear of the potential or existing threats. Ensure that the overall refueling area is clean, dry, and open with good air ventilation. If the area is confirmed to meet these safe conditions, you can position the Product in the desired fueling location and engage the parking brake and key off the power.

    2- Initial Inspection

    Before attempting to use your Smart Ass Fuel Mule Gas Caddy with Pump to dispense fuel, make any necessary repairs to leaks around the seals or connections in the fuel system, hoses, swivels, joints, threads, etc. Make sure the hose is in good condition with no signs of wear or drying/cracking and connections are tight. Ensure the operating area is dry and free from fuel, water, or liquid spills. Confirm that the green grounding wire from the pump to the chassis is intact and is not blemished or damaged in any way.

    3- Neutralizing Static Electricity Risk

    When preparing to dispense fuel out of the product using the onboard fuel pump, it is important to handle the different electrical potentials with care. Begin by confirming that the key switch is powered off and facing straight. See Figure 26.

    Smart Ass Fuel Mule Gas Caddy with pump with keyswitch powered off

    Figure 26





    Next remove the fuel nozzle from the holder on the fuel pump. Grab the conductive part of the fuel nozzle, the bare metal portion, and with the other free hand grab the conductive metal portion of the vessel being filled if the product contains a conductive bare metal body or grounded chassis. If the fill vessel does not have a conductive fill neck, grab another bare metal part of the vessel that is grounded. Grabbing both elements with your bare hands will neutralize the electrical potential between the two systems, the Product and the vessel being filled. Once neutralized, you can now insert the nozzle into the fill neck/port of the product being filled. See Figure 27.I

    How to nuetralize static electricity safely before pumping from your Smart Ass Fuel Mule Gas Caddy with pump

    Figure 27





    From here, the antistatic grounding wire built into the fuel nozzle of the Product will continue neutralizing the potential of both systems through the metal nozzle contacting the conductive fill neck of the desired product being filled (if the fill neck is also conductive).

    4- Powering the Pump

    With the nozzle now in the vessel being filled, ensure that the nozzle is closed and not open for dispensing. Once confirmed, go to the Steering Arm and power on the pump by switching the key switch to the clockwise position. With the Fuel Pump now receiving power, go to the fuel pump itself and lift up the lever which powers on the pump. The lever is located under the nozzle holder and when powered on will be covering the opening that the nozzle is stored.

    5- Dispensing Fuel

    With the fuel pump now pressurizing the fuel line, you can now press on the fuel nozzle lever dispensing fuel into the approved container or vessel. You may use the auto nozzle feature and allow for automatic nozzle shutoff. While the fuel is dispensing, stand with the Product with your hands ready to kill the emergency stop in the event of any failure, fire, or hazard that arises.

    Stay close to the fuel nozzle as well in the unlikely case that the auto shutoff feature fails, you can quickly shut off the nozzle manually. The fuel dispensing of the fuel pump can take anywhere from 3 to 5 minutes depending on how full the tank on your fuel caddy is and the batteries state of charge.

    6- Shutting off the Fuel Pump

    When you are ready to stop dispensing fuel, ensure that the fuel nozzle lever is now off and is no longer dispensing fuel. Next shut off the fuel pump using the switch on the fuel pump itself. Switching the lever down to the off position will open up the holder location for the fuel nozzle to be stored again. Next go to the Steering Arm and switch the key switch into the off position to reassure all power to the fuel pump is off. With the fuel pump now fully powered off, let the last few drops fall into the vessel, it can help to jiggle it a bit as you remove the nozzle to eliminate any drips. Place the fuel nozzle back in the holder located on the fuel pump. This concludes all the fuel dispensing steps and you may now drive/return the Product to a safe storage location.





    Smart Ass Fuel Mule Gas Caddy - Driving Best Practices

    Before driving the Product, it is crucial for the operator to understand the best practices to ensure utmost safety and performance.

    Operators and bystanders should always position themselves uphill from the Product during operation, whether driving the product uphill or downhill. This precautionary measure reduces the risk of potential accidents, ensuring that in the event of a loss of control or if the Product begins to roll, individuals are positioned in a safe location to avoid being run over or crushed by the Product. See Figures 28 and 29.

    Always stay uphill of your Smart Ass Fuel Mule Gas Caddy with pump

    Figure 28





    When navigating the Product downhill, it is advised to operate the Product in reverse with the steering arm and operator positioned uphill of the product. This positioning enables the operator to maintain better control and modulation of speed (via the brake lever) using both hands while ensuring that no user or operator is in the path of the product should the operator stumble or lose control and the Product begin to roll. See Figure 29.

    Always stay uphill of your Smart Ass Fuel Mule Gas Caddy with pump when going downhill

    Figure 29





    When traveling uphill, it is advised to also operate the Product from the uphill side. When traveling both uphill and downhill, it is advised that the operator is uphill of the Product and the Product is orientated with the steering arm on the uphill side. See Figure 30.

    Always stay uphill of your Smart Ass Fuel Mule Gas Caddy with pump when going uphill

    Figure 30





    Do not exceed the slope limitations specified for the Product, these limits can be found in the “Operating Conditions” section. Operating the Product on excessively steep inclines or declines can compromise stability, traction, and control increasing the risk of accidents, tip-overs, or loss of control.

    Do not operate the Product on surfaces or structures incapable of supporting the weight of the Product. This includes lighter duty truck tailgates that may not be rated for 600lbs. Your Smart Ass Fuel Mule Fuel Caddy with Pump can see weights close to 600Lbs total depending on the fuel used and capacity of the tank. For more detailed product weight specifications, see the “Fuel Compatibility Statement” section of this user manual.

    Do not approach fore/aft inclines (pitch) at a side to side (roll) angle. Inclines are to be driven head on for optimal performance and reduced risk of tipping hazards. By head on, this refers to the only direction of incline or decline being in the “Pitch” condition, as mentioned in “Operating Conditions” section.

    Do not attempt to modify or tamper with any of the product components, as it may void the warranty and compromise safety.

    Do not operate the Product under the influence of alcohol, drugs, or medication that may lead to impaired judgment and or reaction time.

    Maintain a safe distance from edges, ledges, or structures that may pose a risk of tipping or falling during operation. Modulate throttle, always ready on the brakes, if you’re near any sort of obstacle or ledge. In short, don’t be a dumb donkey and run your Fuel Mule off of anything. Be a Smart Ass!

    If operating the product through rough terrain (specifically climbing inclines) and you experience symptoms such as a decrease in speed, audible electronic whining, or the product not moving as expected, it is essential to take immediate action. Stop operating the Product immediately, apply the hand brake, and reassess the terrain you are traversing. These signs may indicate that you are pushing the unit beyond its designed capabilities. In such instances, the Product’s internal override power cut mechanism may engage. To prevent damage to the motor, the motor controller is programmed to cut power to the motor when overdrawn, to prevent damage to the electronics. This power cut safety feature is a safety feature, but without proper usage, can be potentially dangerous if the operator is not aware or expecting it. So be aware. Continuing to operate the Product under these conditions may compromise its performance, durability, and safety of the Product, of the Operator, and of other persons or property. Therefore, operate with caution and adjust your chosen path to ensure safe and optimal operation of the Product that are within its limitations.

    Please adhere to all federal, state, and local laws and regulations/guidelines regarding the operation of the Product. Ensure that you are operating the Product in areas where its use is permitted and in compliance with applicable laws and regulations.

    Do not power on the Product while the Product is charging. Ensure the Product is unplugged before attempting to move or power on the Product.





    Smart Ass Fuel Mule Gas Caddy - Loading & Unloading Best Practices

    The Product was designed to be loaded into and out of a transportation vehicle, whether the bed of a pickup truck, box or flatbed truck, or trailer. Utilize these best practices for safe and efficient operation.

    Use ramps that are rated to support the full weight of the Product and the operator. For more details on this, refer back to the section “Loading Procedure” section of this user manual.

    The operator is responsible for confirming the ramps traction potential and incline before loading and unloading the Product. If the slope is greater, longer ramps may be needed and a better loading and unloading location with less of an incline is needed. Longer ramps will reduce the slope, as will creatively selecting a loading location using a higher point on the ground, a small hill for example, to reduce the ramp incline. Back the truck near the hill, truck still on flat ground, such that the end of the ramps will be resting at an elevation higher than the truck tires. This will reduce ramp incline.





    Smart Ass Fuel Mule Gas Caddy - Storing Conditions

    The Product should be stored with care in safe locations that meet the requirements outlined in this section.

    Do not store in poorly vented areas. To prevent the presence of fuel vapor build up, only store the product in well-ventilated and preferably outdoor conditions.

    Do not store in locations where it may have exposure to open flames, spark sources, ignition sources, heaters, or running vehicles.

    Do not store the product where it can have direct or indirect exposure to weather and its elements such as direct sun, rain, hail, and other inclement weather.

    For maximum longevity of the batteries, it is best to avoid storing the Product in temperatures outside the range of 32°F to 75°F.

    Ensure that the storage location is secure and inaccessible to unauthorized individuals, especially children.

    If storing the Product for a long period of time, ensure that the approved substance in the container has adequate properties to be stored for the intended duration to avoid negatively affecting the fuel.

    Avoid storing in areas with high humidity or moisture levels as this can potentially lead to corrosion and damage to components on the Product.





    Emergency Procedures

    This section of the user manual helps train you to react to specific events. Knowing what to do in the instance of a dangerous situation or emergency is crucial for safety of the operator or bystanders.

    If a Fire Starts When Fueling.

    If a fire starts when fueling, it is key to get persons in the area to safety as quickly as possible. From the “Fuel Filling Procedure”, you as the operator should be positioned ready to hit the Emergency Stop at any moment. At the first sign of danger or a fire, if safely possible, immediately hit the emergency stop. If this is not possible to do in a safe manner, immediately step back away from the unit as quickly as possible and find a safe location a safe distance away, this could be 50’ or more away. Do not attempt to shutoff or remove the nozzle anything else as this will increase your potential risk of injury staying close to the danger. Once you are away in a safe location, notify the local police by dialing 911 and reporting the incident. From there you should take the direction of the authorities.

    Loss of Footing While Operating on Ramps.

    If you are operating the Product on ramps and you lose your footing causing you to stumble or fall, it is best to ensure your safety and let go of the handlebar and attempt to fall out of the path and direction of the Product. As outlined in this user manual, the operator or any bystanders should NEVER be in the downhill path of the machine meaning the short rolling distance the Product may travel to will be free of any bystanders or operators keeping all person(s) safe from crushing or impact hazards.

    Operating on an incline and the Product begins tipping over.

    The Product is designed to handle a limited amount of incline and when users exceed these limitations on the product or operate on a loose surface limiting traction, they risk putting themselves or others at risk. In this instance a tipping event can occur. If the Operator exceeds the product limits and the Product begins to tip, it is not advised to try to muscle the handlebar and lower the machine. Rather the operator is advised to let go of the handlebar and relocate themself to a safe direction out of the tipping direction.

    The product falls into a body of water with contents still in the tank

    If during operation the Product enters or falls into a body of water, the operator should prioritize their own safety. They should attempt to safely position themselves out of the path of falling or danger if they notice the Product falling towards the body of water. Once safely positioned on the dock, if possible, the operator should activate the emergency stop to prevent any power to the systems onboard the Product. If the Product is carrying any fuel, the operator should take immediate action to prevent any fuel from spilling into the water. This may involve ensuring the fill cap is still screwed on tight and the fuel nozzle is closed and not dispensing fuel. Additionally, if fuel absorbent materials are available to contain the spill, this can also be utilized. Contact the local emergency services, such as the fire department or coast guard, to report the incident and request assistance. Provide them with any details about the location of the incident and any potential environmental hazard such as fuel spillage and flammable content presence. Once authorities are notified, retrieving the fuel mule is the next task. Observing the depth of the water and accessibility of the Product, this may constitute the methods used to retrieve it such as special equipment, recovery services, or calling professionals.

    Fuel Spill

    In the instance that a fuel spill occurs, it is advised to take action immediately. If fuel has spilled, immediately ensure all power to the Product is killed, using both the key switch and Emergency Stop. Ensure there are no immediate fire threats such as open flame, spark sources, ignition sources, or heat sources that could potentially ignite the spilled fuel and or vapors. Next, take all necessary steps that are both reasonable and safe to stop the continuation of spilling. This could be tightening the fuel cap, shutting off the fuel nozzle, or attempting to right the Product if it has tipped.

    Wait 1 hour after any fuel spill and after ensuring product is dry and clear of any fuel remaining on the product before powering on the Product and operating it again. This practice prevents any possible ignition sources from being present while fuel spill and vapors are present in excess.

    Once the spilling has been reasonably contained depending on the state you are in, it is required to report the fuel spill if it exceeds your states reporting amount. Please confirm with your state’s local guidelines and regulations for the minimum fuel spill that requires reporting. Following your states guidelines, make the report and proceed with the appropriate clean up measures that are both reasonable and safe. The measures also may be recommended or guided by local authorities and it is best to confirm with them on what they advise for the scenario at hand.

    Operating the Product on excess inclines straining the components and power cutoff occurs

    If you hear the components making a whining or screeching sound, this means you are overpowering the system and it cannot handle the load. This indicates you are carrying either too much weight, or carrying it at too much incline. After two seconds of hearing this sound when driving the machine, the safety power cut off will be engaged in the motor controller to prevent damage of the components. To avoid the power cutting in an unsafe location, immediately let off the throttle while simultaneously engaging the hand brakes when you first hear this sound. Slowly back off the incline or maneuver the Product off the incline as this is exceeding the limits of the Products capability. Once in a safe location, choose a safer option with less incline within the Products limits to proceed. If continuing to operate the machine in the overstrained state and the power cuts, the first response is to fully engage the hand brake and stop the Product from moving. If you are unable to do so and the product begins rolling, it is advised to let go of the handlebar and locate yourself into a safe location out of the path or direction of the Product. The Product can be assessed after it comes to a stop and is off the incline.

    3) Inspect the wiring from the motor to the battery box, if visual damage such as pinches, cuts, or tears is observed, it is advised to replace the motor (wiring is attached to motor)
    4) Having tested all prior components, if the motor controller tests successfully, replacing the motor is advised. Contact Smart Ass Customer Service for next steps.

    D) Key on drive motor, Product moves in one direction, reverse switch is toggled and the Product does not change direction when throttle is re applied.

    1) Toggle Switch not fully engaged
    2) Thumb Throttle connector

    1) Toggle the reverse switch on and off again firmly confirming it latched. Wait a few seconds and then try to apply throttle. If still no reverse function, proceed to next "Possible Issue".
    2) Observe the wiring of the thumb throttle confirming that it is fully plugged in. There is one connection in the handle electronics box near the key switch. Gently pull out the thumb throttles wire and confirm the plug is firmly connected, then tuck it back into the handle electronics box. Next proceed to the steering arm connector that plugs into the battery box. Check for loose wires or terminals that pulled out. If no problem is observed, Contact Smart Ass Customer Service for next steps.

    If repairs are needed beyond that which is covered in the above troubleshooting section, please contact Smart Ass Customer Service and we will provide guidance on next steps.







    Section 7: Maintenance

    Maintaining your Product properly is paramount for keeping high level safety, performance, and longevity. There are several components on the Product that should be maintained and routinely checked for wear and functionality.



    Batteries

    The Product utilizes two 12V VRLA AGM batteries in series to create the 24V system. This battery style is designed for 100 – 300 cycles with a life expectancy of 3-5 years. To maintain the best performance of your Products battery system, charging the battery according to the “Charging Procedure” in this user manual is a big contributing factor. Refrain from deep cycling the battery and constantly running them to a low capacity as this will shorten the batteries lifespan. Avoid storing the batteries below 90% capacity. It is recommended by the battery manufacturer that the operation environment for longevity of the batteries is between 20°C and 30°C (68°F to 86°F). Batteries should be replaced every 3 years or upon notice of failure, reduced battery life, reduced power output, or any additional signs of battery wear impacting the performance. Not proactively replacing the batteries may cause an increased risk of failure during operation which depending on the operation environment and conditions, could result in a major injury or even death.



    Tires and Tubes

    The wheels and tires, like a standard automotive vehicle, experience wear and tear and need to be observed on a regular basis. The wheels on this product contain a tire and a tire tube that need to be monitored. Firstly, standard operating pressure for the tires on this Product is 30psi. These pressures should be observed before every use to ensure optimal traction and even tire wear.

    Next, tire tread. These tires come with tire tread that is semi-aggressive for hybrid concrete and off road use. The tread depth should not fall below 1/8 th of an inch. Anything below this level increases the safety hazard as reduced traction becomes present. This measure can be taken with a standard tread depth tool from a local auto parts store.

    The tire tubes are airtight tubes that are inserted between the rim and tire that hold the tires pressure. If the tire itself is punctured, that does not always mean the tire tube was damaged and visa versa. The tire tube may be damaged even if there is no visible damage to the tire. That being said, the only way to judge functionality of the tire tube is by measuring pressure. If you measure the tire pressures weekly and notice a pressure drop at all, this may be a sign that the tire tube is bad or has a leak of some sort. If this is observed, it is advised to replace the tire tube.



    Chain

    The Smart Ass Fuel Mule Gas Caddy is propelled by a chain drive system. This is located underneath the Product near the rear wheel. The chain should have a certain amount of slack to allow for proper motion and functionality. The chain tension should be observed monthly to notice for signs of slack or stretching. If the chain is too tight can cause component damage and excess wear and grinding. If the chain is too loose may derail and come off.

    The chain must be tensioned with the proper amount of slack. See the diagram below illustrating approximately .4” of slack from center, .8” total. If the chain is observed to have too much or too little tension, it should be adjusted.

    IMPORTANT: Before ever touching the chain or sprocket components, ensure both the key switch is off and the Emergency Stop is activated cutting all possible power to the motor. To adjust the tension, loosen the 4x bolts and nuts that are mounting the motor mount plate to the frame. This will allow for linear motion to slide the motor forward and backward to loosen or tighten the chain. Once the optimal tension is found, secure the hardware to lock the motor mount plate back in place.

    Chain lubrication is also important for longevity. Be sure to lube the chain at least quarterly, or monthly with heavy use. Use roller chain lubricant commonly found at most bicycle or automotive shops. Chain lubrication is especially important if the chain is dry or gets very dirty with dust, mud, and other elements.



    Brake fluid

    The braking system is a hydraulic disc brake system that uses DOT 3 brake fluid. The fluid reservoir is located on the steering handle built into the steering lever. There is a level indicator glass to check for the level and clarity of the brake fluid. Like automobiles, the brake fluid should be changed periodically. If the brake fluid is low and the fluid is still clear and clean, free of particles, debris, and coloration, you may top it off using approved DOT 3 brake fluid only.

    If your brake fluid is observed to be dirty or colored, as in a yellow or brown/black tint to it, it is advised to flush the brake fluid entirely. To do this, please refer to “Repairs” section of this user manual.

    Brake fluid is also susceptible to aging and needs to be routinely flushed every 2 years. Replace the brake fluid by doing a complete flush every 2 years to prevent failure and risk of compromised or weakened braking.



    Brake Pads

    Brake pads will wear with use and will show signs when the pads begin to wear out to the point of replacement. Brake pads will often times start to make a noise during braking signifying wear and need for replacement. If the brake pads start making a screeching noise during braking, they should be replaced. If the brake lever pressure has not changed but the product’s ability to stop feels weaker than it used to be, the brake pads should be inspected and replaced if found to be the root cause. If the brake bad thickness is at or below 1/16”, the pads should be replaced. Operators should verify there is ample brake pad available before every use by looking at brake pad through the gap in the caliper where brake pad thickness is visible. To see how to replace the brake pads, refer to the ”Repairs” section of this user manual.



    Brake Disc

    The brake discs can also wear and need replacement similar to that of the brake pads. It is important to look for any signs of brake disc wear such as deep grooves on the disc's surface, a noticeable lip on the edge of the disc, cracks, splits, or other structural problems, uneven wear in the disc, warped disc, excessive noise or vibration during braking, and/or decreased stopping power or ability. With any of these symptoms noticed, it is recommended to replace the brake disc. To see how to replace the brake disc, refer to the ”Repairs” section of this user manual.
