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).
