17 Checking the Chain Saw
The saw will switch on and the chain will start
rotating.
The saw will not switch on until the trigger switch
lockout and retaining button have been
depressed and the trigger switch has been
squeezed.
If the trigger switch and the trigger switch lockout
are released, the "STATUS" LED and the LED of
the current power level will remain flashing for
approximately 1 second. As long as the LEDs
are flashing, the saw can again be switched on
without pressing the retaining button.
The further the trigger switch is squeezed, the
faster the saw chain will rotate. When power
level is selected, the trigger switch
does not have to be fully pressed to reach the
maximum power.
16.2 Switching Off
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 remove the battery before
transporting or putting the chain saw down.
To switch the chain saw off:
► Release the trigger switch and trigger switch
lockout so that the trigger switch springs back
to the locked position. In the locked position,
activation of the trigger switch is blocked by
the trigger switch lockout. Activation of the
chain saw is also electronically blocked by the
retaining button once the "STATUS" LED
stops flashing (after approximately 5 seconds).
The saw chain will continue to rotate for a short
time after the trigger switch is released. Take
care to avoid contact after releasing the trigger
switch and when setting down the chain saw.

17 Checking the Chain Saw
17.1 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,
► Switch on the chain saw,
► Engage the chain brake by pushing the front
hand guard, 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.
17.2 Testing the Controls
Before starting work, confirm that the trigger
switch lockout (1), retaining button (2) and trigger
switch (3) are undamaged and functioning prop‐
