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.
Throttle
The lever controls engine speed.
Pull throttle handle toward the handle bar to
increase engine speed.
CONTROLS
WARNING!
Gasoline is highly flammable.
Observe caution and fill the tank
outdoors. (See the safety

system, become very hot during
operation.
Risk for burns if touched.
Allow engine and exhaust
system to cool at least two (2)
minutes before refueling.
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.
