Cleaning the spark plug
The spark plug is located behind the air
filter. Remove the spark plug using the
spark plug spanner supplied. Remove
any deposits using a wire brush.
Use a feeler gauge to check that the
spark gap is 0.6-0.7 mm and adjust if
necessary.
If the spark plug is very sooty, clean or
replace it. Always replace with the same
type.
Idling adjustment
If the chainsaw is not running smooth-
ly, the idling speed can be adjusted.
Clean the air and fuel filters first and
check that the fuel and chain oil are
mixed correctly (1:40).
Start the engine.
Adjust the idling speed by turning the
T screw. The chain must not move
around the blade when the engine idles.
All other settings of the carburettor may
only be changed by a professional.
Checking the chain wheel
Remove the side plate and check the
chain wheel. If the chain wheel's teeth
are more worn down than 5 mm, re-
place the chain wheel with a new one
of the same specifications as the old
one.
