Operation

Using Stabilizer/Conditioner

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

•Keeps gasoline fresh during storage of 30 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 Add the correct amount of gas stabilizer/conditioner to the gas.

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.

Gasoline/Alcohol blends

Gasohol (up to 10 percent ethyl alcohol, 90 percent unleaded gasoline by volume) is approved for fuel use by the engine manufacturer. Other gasoline/alcohol blends are not approved.

Filling the Fuel Tank

1.Shut the engine off and set the motion controls to the neutral position and engage parking brake.

2.Clean around the fuel tank cap and remove the cap.

3.Add unleaded regular gasoline until the body of the tank is full but fuel does not fill the neck of the tank (Figure 6). This space in the neck of the tank allows gasoline to expand. Do Not fill the fuel tank completely full.
