Engine Running Behavior
If engine running behavior is still
unsatisfactory after servicing the air filter
and adjusting the throttle cable, 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.

Sharpening Metal Cutting
Blades
Use a sharpening file (see "Special
N
Accessories") to sharpen dull
cutting attachments. In case of
more serious wear or nicks:
Resharpen with a grinder or have
the work done by a dealer – STIHL
recommends a STIHL servicing
dealer.
Sharpen frequently, take away as
N
little metal as possible – two or three
strokes of the file are usually
enough.
