Holding the ergo-lever (1) down keeps the trigger switch
unlocked. If the operator releases the trigger switch and
ergo-lever, the operator will have to unlock the tool again
with the trigger switch lockout. The motor will not switch on
unless the hand guard is set to 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.

18.2 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 Ergo-Lever so that the
trigger switch springs back to the locked position. In the
locked position, activation of the trigger switch is once
again blocked by the trigger switch lockout.

19 Checking the Chain Saw

19.1 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.
