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.
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 to 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.
19.2 Testing the Controls
Before starting work, confirm that the ergo-
lever (1), trigger switch lockout (2) and the trigger
switch (3) are undamaged and functioning prop‐
erly.

When you release the trigger switch lockout, it
should remain unlocked as long as you hold
down the ergo-lever.

with both hands, your left hand on the front
handle and your right hand on the control han‐
dle. Release the chain brake and switch on
