  • Before operating, always inspect the machine to ensure that the components and hardware are in good working condition. Replace worn or damaged components and hardware.

Fuel Safety

  • Fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

    • To prevent a static charge from igniting the fuel, place the container and/or machine directly on the ground before filling, not in a vehicle or on an object.

    • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

    • Do not handle fuel when smoking or around an open flame or sparks.

    • Do not remove the fuel cap or add fuel to the tank while the engine is running or hot.

    • If you spill fuel, do not attempt to start the engine. Avoid creating a source of ignition until the fuel vapors have dissipated.

    • Store fuel in an approved container and keep it out of the reach of children.

  • Fuel is harmful or fatal if swallowed. Long-term exposure to vapors can cause serious injury and illness.

    • Avoid prolonged breathing of vapors.

    • Keep your hands and face away from the nozzle and the fuel-tank opening.

    • Keep fuel away from your eyes and skin.

  • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or on other appliances.

  • Do not fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground, away from your vehicle before filling.

  • Remove the equipment from the truck or trailer and refuel it while it is on the ground. If this is not possible, then refuel from a portable container rather than a fuel-dispenser nozzle.

  • Do not operate the machine without the entire exhaust system in place and in proper working condition.

  • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

  • If you spill fuel on your clothing, change your clothing immediately. Wipe up any fuel that spills.

  • Never overfill the fuel tank. Replace the fuel cap and tighten it securely.

Fueling the Machine

Fuel Specification

Petroleum fuelUse unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

    Operating Tips

    Refer to the attachment Operator's Manual for specific operating instructions for any installed attachments.

    Practice driving the machine; when operating the machine, consider the characteristics of ground speed and engine speed:

    • To transfer maximum power to the wheels, move the throttle control to the FAST and slightly press the traction controls forward.

    • Maintain constant engine speed by pressing the traction controls slowly; this allows the engine to keep up with the ground speed of the vehicle.

    • Pushing the traction controls too quickly reduces the engine speed; which can reduce the torque-power that moves the vehicle.

    • Alternatively, maximum ground speed is achieved when the throttle control is in the FAST position and the traction controls are slowly but fully pressed.

    Note: If the attachment adapter becomes stuck to the traction unit adapter, insert a pry bar or a screwdriver into the pry slot to disengage the parts (Figure 57).
