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.
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.
WARNING!
Fill to bottom of filler neck. Do not
overfill. Wipe off any spilled oil or fuel.
Do not store, spill or use gasoline near
an open flame.
WARNING!
The engine and the exhaust system,
become very hot during operation.
Risk for burns if touched.
Allow engine and exhaust system to
cool before refueling.
WARNING!
Gasoline is highly flammable. Observe
caution and fill the tank outdoors (see
the safety instruction).
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.
