Devices for Reducing the Risk of
Kickback Injury
STIHL recommends the use of the
STIHL Quickstop chain brake on your
chain saw with green labeled reduced
kickback bars and low kickback saw
chains.
WARNING
To reduce the risk of injury, never use a
saw if the chain brake does not function
properly. Take the saw to your local
STIHL servicing dealer. Do not use the
saw until the problem has been rectified.

STIHL Quickstop Chain Brake
STIHL has developed a chain stopping
system designed to reduce the risk of
injury in certain kickback situations. It is
called a Quickstop chain brake.
There are two mechanisms for activating
the chain brake if it is in a properly
maintained condition:
manual activation: If a kickback
–
occurs, the chain saw moves
upwards towards the user in a
rotating motion around the front
handle. The brake is designed to
engage if the left hand contacts the
front guard, which is the activation
lever for the brake, and pushes it
forward.
inertia activation: All STIHL chain
–
saws are equipped with an interia
Quickstop chain brake. If the
kickback impulse is strong enough,
this alone is sufficient to engage the
brake even without contacting the
front hand guard.
