21 Engine Running Behavior
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 author‐
ized STIHL servicing dealer.

22 Lubricating the Gearbox

Use STIHL gear lubricant (special accessory) for
lubrication.
► Check grease level about every 100 hours of
operation.
► Unscrew the filler plug (1). If no grease can be
seen on the inside of the filler plug, screw the
tube of lubricant (2) into the filler hole.
► Squeeze up to 5 g grease into the gearbox.
NOTICE
Do not completely fill the gearbox with grease.
► Refit the filler plug and tighten it down firmly.
