On all spark plugs:
:
Always press the boot (

firmly
on
to the spark plug (

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 in the muffler.
Have your STIHL dealer inspect the
muffler for carbonization.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers.

Check grease level regularly –

brushcutters – see "Special
Accessories" – into the filler hole.
:
Squeeze up to 5 g grease into the
gear housing.
Do not completely fill the gear
