Operation

Before Operation

Note: Determine the left and right sides of the machine from the normal operating position.

Before Operation Safety

General Safety

  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.

  • Check that all guards and safety devices are in place and working properly.

  • Always inspect the machine to ensure that the blade, blade bolts, and cutting assembly are not worn or damaged.

  • Inspect the area where you will use the machine and remove all objects that the machine could throw.

Fuel Safety

Danger

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.

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

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

  • Keep fuel away from your eyes and skin.

Recommended Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline 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.

  • 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 a fuel stabilizer/conditioner in the machine to provide the following benefits:

  • Keeps gasoline fresh during storage of 90 days or less. For longer storage it is recommended that the fuel tank be drained.

  • Cleans the engine while it runs

  • Eliminates gum-like varnish buildup in the fuel system, which causes hard starting

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

    Add the correct amount of fuel stabilizer/conditioner to the gasoline.

    Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.

Filling the Fuel Tank

  1. Park the machine on a level surface and shut off the engine.

  2. Allow the engine to cool.

  3. Clean around the fuel-tank cap and remove it (Figure 7).

  4. Add fuel to the fuel tank until the level of fuel is at the bottom of the filler neck.

  5. Install the fuel-tank cap securely.

  6. Wipe up any fuel that may have spilled.

Checking the Engine-Oil Level

Before you start the engine and use the machine, check the oil level in the engine crankcase; refer to Checking the Engine-Oil Level.
