fuel pump bulb at least five times –

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".
Filters have an average life of more than 
a year. Do not remove the filter cover or 
replace the air filter as long as there is no 
noticeable loss of power.
If there is a noticeable loss of engine 
power
N Turn the choke knob to g.
N Loosen the screws (1).
N Remove the filter cover (2). 
N Clean away loose dirt from around 
the filter.
N Remove the filter element (3).
N Replace dirty or damaged filter 
element (3).
N Replace any damaged parts.
Installing the Filter Element
