Adding Fuel

Danger

In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

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

  • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows the fuel to expand.

  • Never smoke when handling fuel, and stay away from an open flame or where a spark may ignite the fuel fumes.

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

  • Never buy more than a 30-day supply of fuel.

Warning

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 face away from the nozzle and fuel tank or conditioner bottle opening.

  • Avoid contact with skin; wash off spills with soap and water.

Fuel Specification

Petroleum fuelUse unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).
Ethanol blended fuelUse an unleaded-gasoline blend with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same.
Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

Important: For best results, use only clean, fresh fuel (less than 30 days old).

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Using Stabilizer/Conditioner

Use fuel stabilizer/conditioner in the machine at all times to keep the fuel fresh longer when used as directed by the fuel-stabilizer manufacturer.

Important: Do not use fuel additives containing methanol or ethanol.

After Operation

General Safety

  • Park machine on level ground, disengage drives, set parking brake, stop engine, remove key or disconnect spark plug wire. Wait for all movement to stop and allow the machine to cool before adjusting, cleaning, repairing, or storing. Never allow untrained personnel to service machine.

  • Clean the machine as stated in the Maintenance section. Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.

  • Frequently check for worn or deteriorating components that could create a hazard. Tighten loose hardware.

Loading the Machine

Use extreme caution when loading machines on trailers or trucks. Use a full-width ramp to extend beyond the rear tires instead of individual ramps for each side of the machine. With the platform up, a full-width ramp provides a surface to walk on behind the machine.

A steep ramp angle may cause components to get caught as the machine moves from ramp to trailer or truck. Steeper angles may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramps extends up the slope. This minimizes the ramp angle. The trailer or truck should be as level as possible.

Important: Do not attempt to turn the machine while on the ramp, you may lose control and drive off the side.

Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.

Hauling the Machine

Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all the necessary lighting and marking as required by law. When using a trailer, secure it with the safety chains.

  1. Load the machine onto the transport vehicle.

  2. Lock the tines in the up position by tapping and holding the multi-function switch in the down position until the LED indicator appears on the hour meter/tine engagement display.

  3. Engage the parking brake, shut off the engine, and remove the key.

  4. Close the fuel-shutoff valve.

  5. Block the wheels and securely bind the machine to the trailer or truck with straps, chains, cable, or ropes. If possible, both front and rear straps should be directed down and outward from the machine.

    Important: Use only the 4 designated tie-down locations on the machine—2 on the left side and 2 on the right; refer to Figure 29.

g212139

Figure 29

Left side shown

  1. Tie-down location

Caution

This machine does not have proper turn signals, lights, reflective markings, or a slow-moving-vehicle emblem. Driving on a street or roadway without such equipment is dangerous and can lead to accidents causing personal injury. Driving on a street or roadway without such equipment may also be a violation of state laws and the operator may be subject to traffic tickets and/or fines.

Do not drive the machine on a public street or roadway.

Warning

Loading a machine on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death.

  • Use extreme caution when operating a machine on a ramp.

  • Use only a single, full-width ramp; Do not use individual ramps for each side of the machine.

  • Avoid sudden acceleration or deceleration while driving machine up or down a ramp to avoid tipping backward.

    Jump Starting a Discharged Battery

    The following instructions are adapted from the SAE J1494 Rev. Dec. 2001 – Battery Booster Cables – Surface Vehicle Recommended Practice (SAE – Society of Automotive Engineers).

    Danger

    Jump starting a weak battery that is cracked, frozen, has low electrolyte level, or an open/shorted battery cell, can cause an explosion resulting in serious personal injury.

    Do not jump start a weak battery if these conditions exist.

    Warning

    Batteries contain acid and produce explosive gases.

    • Always shield your eyes and face from the battery.

    • Do not lean over the batteries.

    Preparing to Jump Start the Battery

    Caution

    Corrosion or loose connections can cause unwanted electrical voltage spikes at any time during the jump starting procedure.

    Do Not attempt to jump start with loose or corroded battery terminals or damage to the engine may occur.

    1. Check the cable clamps and battery terminals of the discharged battery for corrosion (white, green, or blue “snow”) and check that the hardware for the clamps is tight.

      Clean corrosion from the battery terminals and cable clamps.

    2. Check that the hardware for the cable clamps is tight.

      Tighten the cable-clamp hardware as needed.

    3. Check that the vent caps on the discharged battery and booster battery are tight and level.

    4. If available, place damp clothes over the vent caps of both batteries.

    5. If you are jump starting from the battery in another vehicle, ensure that it has a 12 V lead acid battery.

      Important: Ensure that the 2 vehicles do not touch.

    6. Ensure that the booster battery is fully charged with 12.6 V or greater.

    7. Select properly sized jumper cables (4 to 6 AWG) with short lengths to reduce voltage drop between systems.

      Choose jumper cables with color coded or polarity labeled cables or clamps.

    Connecting the Jumper Cables

    Caution

    Connecting the jumper cables incorrectly (wrong polarity) can immediately damage the electrical system.

    Be certain of battery terminal polarity and jumper cable polarity when hooking up batteries.

    1. Connect the positive jumper cable—red (+) to the positive-battery terminal of the discharged battery as shown in Figure 42.

      Note: The positive-battery terminal is wired to the starter or solenoid.
