WARNING
To reduce the risk of personal injury from unintended
activation, disconnect the chain saw from the power supply
and engage the chain brake before inspecting the chain saw
or carrying out any maintenance, @ 9. Carry out only the
maintenance operations described in this manual. There are
no user-authorized repairs. STIHL recommends that repair
work be performed by authorized STIHL servicing dealers.
Proper maintenance of the chain saw includes the following
activities:
► Inspecting the chain sprocket periodically and having a
worn chain sprocket replaced by an authorized STIHL
servicing dealer.
► Inspecting the guide bar for proper groove depth and
spread and replacing the guide bar if it shows signs of
excessive wear or damage.
