17 Operating Instructions

17 Operating Instructions
17.1 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 dur‐
ing 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.
17.2

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.
17.3

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".

18 Cleaning the Air Filter

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

engine power

► Loosen the screw (1) and remove the filter
cover (2).
► Clean away loose dirt from around the filter.
► Remove the foam and felt filter elements.
► Wash the foam element in a clean, non-flam‐
mable solution (e.g. warm soapy water) and
then dry.
► Fit a new felt element – do not wash. As a
temporary measure you can knock it out on
the palm of your hand or blow it out with com‐
pressed air.
Replace any damaged parts.
