English
￭ If the chain saw or battery is damaged, not working
properly, has been left outdoors or dropped into water or
other liquid, its components may no longer function
properly and safety devices may be inoperative. To

– Take the chain saw and battery to your authorized
STIHL servicing dealer to be checked before further
operation.
￭ Genuine STIHL replacement parts are specifically

Using the Chain Saw

5.5.1 Before Operation
WARNING
￭ Misuse or unauthorized use may result in personal injury
and property damage.
– Use the chain saw only as described in this
instruction manual.
￭ For proper assembly of the bar and chain:
– Read and follow the instructions on mounting the
guide bar and chain, @ 15.2.1.
￭ The chain, guide bar and sprocket must match each other
in gauge and pitch. Before mounting or replacing:
– Read the information on guide bar and chain
combinations, @ 28.

5 IMPORTANT SAFETY INSTRUCTIONS
￭ Proper tension of the chain is extremely important to
maximize cutting performance and reduce the risk of
personal injury from chain breakage, derailment or
reactive forces:
– Never cut with a loose chain. If the chain becomes
loose while cutting, switch off the motor, engage the
chain brake and remove the battery from the chain
saw before tightening the chain. Never attempt to
adjust the chain while the battery is inserted.
– Read and follow the chain tensioning instructions,
@ 15.3.
– Always make sure the chain sprocket cover is
tightened securely after tensioning the chain in order
to secure the bar. Never start the chain saw with the
chain sprocket cover loose or missing.
– Check chain tension once more after tightening the
chain sprocket cover.
– Check chain tension periodically thereafter at
regular intervals (only after engaging the chain brake
and removing the battery).
￭ Using a chain saw that is modified, damaged, improperly
adjusted or maintained, or not completely and securely
assembled can lead to a malfunction and increase the risk
of serious personal injury or death.
– Never operate a chain saw that is modified,
damaged, improperly maintained or not completely
and securely assembled.
– Always check your chain saw for proper condition
and operation before starting work, particularly the
trigger switch, Ergo-Lever, trigger switch lockout,
front hand guard, chain brake and cutting
attachment.
– Ensure that the trigger switch, Ergo-Lever and
trigger switch lockout move freely and always spring
back to the locked position when released. The
trigger switch must not engage until the trigger
switch lockout is depressed.
– Never attempt to modify or override the controls or
safety devices in any way.
