CONTROLS
Fuel tank
Underneath the tank, there is a fuel filter combined
with the fuel valve. The tank volume is 1.72 Gal.
(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 “bolts” 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.
Cutting unit
Dead man’s grip bar
The bar must be held against the handle for the
engine to run. If you release the grip, the ignition
system short-circuits and the engine stops.
WARNING!
Do not bind the bar to the handle.
It is there for your safety.
WARNING!
Gasoline is highly flammable. Observe
caution and fill the tank outdoors. (See
the safety instructions.)
