Use resistor type spark plugs with a
properly tightened adapter nut.
Installing the Spark Plug
N
Screw the spark plug (2) into the
cylinder and fit the boot (1) (press it
down firmly).
If engine running behavior is
unsatisfactory even though the air filter
is clean and the carburetor and throttle
cable are properly adjusted, the cause
may be the muffler.
Have the muffler checked by a servicing
dealer for contamination
(carbonization).
STIHL recommends that you have
servicing and repair work carried out
exclusively by an authorized STIHL
servicing dealer.
N
Check the grease level regularly –
about every 25 hours of operation.
N
Unscrew the filler plug (1). If no
grease can be seen on the inside of
the filler plug, screw the tube (2) of
STIHL gear lubricant (special
accessory) into the filler hole.
N
Squeeze up to 5 g grease into the
gearbox.
NOTICE
Do not completely fill the gearbox with
grease.
