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".
Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.
Your power tool comes standard with
either a clip-on or screw-mounted filter
cover.
If there is a noticeable loss of engine
power
N
Set the choke lever to
g
.
On the clip-on filter cover:
N
Press in the tab (1) and swing the
filter cover (2) away.
On the screw-mounted filter cover:
N
Loosen the screw (3) and remove
the filter cover (2).
On both versions:
N
Clean away loose dirt from around
the filter.
N
Remove the foam and felt filter
elements.
N
Wash the foam element in a clean,
non-flammable solution (e.g. warm
soapy water) and then dry.
N
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 compressed
air.
Replace any damaged parts.
