CONTROLS

Fuel Tank

Read the safety instructions before refueling. The
capacity for each tank is 5-1/2 gallons.
Regularly check the gas cap gasket for damage
and keep the cap properly tightened.
The engine will run on a minimum of 87-octane
unleaded gasoline (no oil mix). Environmentally
adapted alkylate gasoline can be used. See
Technical Data concerning ethanol fuel. Methanol
fuel is not allowed. Do not use E85 alcohol based
fuel. Damage to the engine and components may
occur.
When operating in temperatures below (32°F)
0°C, use fresh, clean winter grade gasoline to
help insure good cold weather starting.
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 must 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 for more information. Do
not use engine or carburetor cleaners in the
fuel tank or permanent damage may occur.
WARNING! Gasoline is highly flammable.
Observe caution and fill the tank outdoors (see
the safety section).
WARNING! Fill to bottom of filler neck.
Do not overfill. Wipe off spilled oil or fuel. Do
not store, spill or use gasoline near an open
flame.

empty parking lot or open field.
3. Back the tracking bolt out until flush with nut.

5. Test operate unit by driving it at full throttle and
the full forward position on both motion control
levers. Gradually turn in the tracking bolt on
the right hand side until the unit noticeably
starts drifting right.

control levers in the full forward position.
