Fuel Tank

Underneath the tank, there is a fuel filter combined
with the fuel valve. Tank capacity is 1.72 gallons (6.5
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 jerks 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 wheel
engages automatically. The centrifugal clutch is
maintenance-free; it is not possible for the user to
make adjustments.

8011-247

WARNING!

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

8011-222b

Use clean, fresh fuel
