CONTROLS
Fuel tank
Underneath the tank, there is a fuel filter combined
with the fuel valve. The tank volume is .95 Gal. (3.6
liters)
Fueling
Read the safety instructions before fueling.
Keep the fuel and fuel tank clean. Avoid filling the
machine with dirty fuel. Make sure the fuel cap is
properly tightened and the gasket is not damaged,
particularly before washing the machine.
Use unleaded gasoline with minimum 86 octane
rating. Never use gasoline mixed with two-cycle
oil. For ethanol and methanol fuel, the following
applies:
Maximum allowable ethanol 10% (volume).
Maximum allowable methanol 5% (volume).
Maximum allowable MTBE (Methyl Tertiary Butyl
Ether) 15% (volume).
If the engine “surges” at normal load it can be
damaged. Change the fuel. If this does not help,
contact an authorized service workshop.
Do not fill the tank completely; leave space for the
fuel to expand as it warms up.
Centrifugal clutch
The engine is equipped with a centrifugal clutch
that is connected to the crankshaft. When the
engine speed increases, the drive for the cutting
blade engages automatically. The centrifugal clutch
needs oil added upon delivery. (10-w30, .53 qt. or
.5 liter.) There are no user servicable parts except
oil level.
To drain oil from the centrifugal clutch the drain is
located on the right side of the crankcase.
WARNING!
Gasoline is highly flammable. Observe
caution and fill the tank outdoors. (See
the safety instructions.)

The lever controls engine speed.
Pull throttle handle toward the handle bar to
increase engine speed.
