At very low outside temperatures
N Set the engine to winter operation if
necessary, see "Winter Operation".
N If the machine is very cold (frost on
machine), allow the engine to warm
up in the Start } position after
starting until normal operating
temperature is reached. Warning:
The cutting attachment runs.
If the engine does not start
N Check that all settings are correct.
N Check that there is fuel in the tank
and refuel if necessary.
N Check that the spark plug boot is
properly connected.
N Repeat the starting procedure.
Fuel tank run until completely dry
N After refueling, press the manual
fuel pump bulb at least five times –
even if the bulb is filled with fuel.
N Start the engine.
During break-in period
A factory-new machine should not be
run at high revs (full throttle off load) for
the first three tank fillings. This avoids
unnecessary high loads during the
break-in period. As all moving parts
have to bed in during the break-in
period, the frictional resistances in the
engine are greater during this period.
The engine develops its maximum
power after about 5 to 15 tank fillings.
During Operation
After a long period of full throttle
operation, allow the engine to run for a
short while at idle speed so that engine
heat can be dissipated by the flow of
cooling air. This protects engine-
mounted components (ignition,
carburetor) from thermal overload.
After Finishing Work
Storing for a short period: Wait for the
engine to cool down. Empty the fuel tank
and keep the machine in a dry place,
well away from sources of ignition, until
you need it again. For longer out-of-
service periods – see "Storing the
Machine".
General Information
The filter has a very long service life.
Do not remove the filter cover or replace
the air filter as long as there is no
noticeable loss of power.
Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.
Replacing the Air Filter
Only if there is a noticeable loss of
engine power
N Set the choke knob to }.
N Loosen the screws (1).
