CONTROLS

Choke Control

The choke control is used for cold starts in order to provide the engine with a richer fuel mixture.

For cold starts the throttle knob should be pushed forward all of the way.

WARNING!

Gasoline is highly flammable. Observe caution and fill the tank outdoors (see Safety).

Refueling

Read the safety instructions before refueling. The machine has one fuel tank, just behind the seat. The tank volume is 3 gallons (11.4 liters).

Make sure the fuel cap is properly tightened and the cap gasket is not damaged.

The engine will run on a minimum of 85-octane unleaded gasoline (no oil mix). Environmentally adapted alkylate gasoline can be used. See also Technical Data concerning ethanol fuel. Methanol fuel is not allowed. Do not use E85 alcohol based fuel. Damage to engine and components may occur.

IMPORTANT INFORMATION

Experience indicates that alcohol blended fuels (called gasohol, ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel the next season. See Storage Instructions for additional information. Never use engine or carburetor cleaners in the fuel tank or permanent damage may occur.
