► Depress and hold the trigger switch lockout (1) with your
thumb.
► While holding the trigger switch lockout, squeeze the
trigger switch (2) with your index finger.
The saw chain will start rotating.
The motor will not switch on unless the hand guard is set to
the position and the trigger switch lockout and trigger
switch are pressed at the same time. Once the trigger switch
is activated and the saw is running, the operator need not
continue to hold down the trigger switch lockout.

WARNING
The saw chain will continue to rotate for a short while after
the trigger switch is released. To avoid serious or fatal injury,
avoid contact with the moving saw chain. To reduce the risk
of personal injury from unintended activation or
unauthorized use, switch off the motor, ensure the chain has
stopped, engage the chain brake and disconnect the chain
saw from the power supply before transporting or putting it
down.

14 Checking the Chain Saw

14.1 Checking the Operation of the Chain Brake

WARNING
Operating the saw with a missing, damaged, modified or
improperly maintained chain brake increases the risk of
severe or fatal injury from kickback. Never attempt to modify
or disable the chain brake. Never operate a saw if the chain
brake has been modified or does not function properly. If you
detect a change in the operating characteristics of the chain
brake, have your saw serviced immediately by an authorized
STIHL servicing dealer.
Before starting work, check the operation of the chain brake:
► Disengage the chain brake, @ 11.2.
► Switch on the chain saw, @ 13.1.
► Engage the chain brake by pushing the front hand guard
to the position, away from the front handle.
A properly functioning chain brake will stop the chain
within fractions of a second.
► If the chain brake fails to stop the chain within fractions of
a second, have the saw inspected and repaired by an
authorized STIHL servicing dealer.
