10 Operating Instructions

10.1 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 helps protect engine-mounted
components (ignition, carburetor) from thermal
overload.
10.2 After Finishing Work
Storing for a short period: Wait for the engine to
cool down. 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".

11 Replacing the Air Filter

Dirty air filters reduce engine power, increase
fuel consumption and make starting more diffi‐
cult.
