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.
WARNING
Never operate your chain saw without a
front hand guard. In a kickback situation
this guard helps protect your left hand
and other parts of your body. In addition,
removal of the hand guard on a chain
saw equipped with a Quickstop chain
brake will disable the activation
mechanism of the chain brake.
WARNING
No Quickstop or other chain brake
device prevents kickback. These
devices are designed to reduce the risk
of kickback injury, if activated, in certain
kickback situations. In order for the
Quickstop to reduce the risk of kickback
injury, it must be properly maintained
and in good working order. See the
chapter of your instruction manual
entitled "Chain Brake" and the section
"Maintenance, Repair and Storing" at
the end of these Safety Precautions. In
addition, there must be enough distance
between the bar and the operator to
ensure that the Quickstop has sufficient
time to activate and stop the saw chain
before potential contact with the
operator.
WARNING
An improperly maintained chain brake
may increase the time needed to stop
the saw chain after activation, or may
not activate at all.
Low Kickback Saw Chain and Reduced
Kickback Bars
STIHL offers a variety of bars and saw
chains. STIHL reduced kickback bars
and low kickback saw chains are
designed to reduce the risk of kickback
injury. Other saw chains are designed to
achieve higher cutting performance or
sharpening ease, but in turn are more
prone to kickback.
STIHL has developed a color code
system to help you identify the STIHL
reduced kickback bars and low kickback
saw chains. Cutting attachments with
green warning labels on the packaging
are designed to reduce the risk of
kickback injury. The matching of green
marked or labeled chain saws with
green labeled bars and green labeled
saw chains gives compliance with the
computed kickback angle requirements
of the chain saw standards when the
products are in their original condition.
Products with yellow labels are for users
with extraordinary cutting needs, having
experience and specialized training for
dealing with kickback.
STIHL recommends the use of its green
labeled reduced kickback bars, green
labeled low kickback saw chains and a
chain saw equipped with a STIHL
Quickstop chain brake for both
experienced and inexperienced chain
saw users.
Please ask your STIHL dealer to
properly match your chain saw with the
appropriate bar/saw chain combination
to reduce the risk of kickback injury.
Green labeled bars and saw chains are
recommended for all chain saws. See
your "STIHL Bar and Chain Information"
leaflet for details.
WARNING
Use of other, non-listed bar/saw chain
combinations may increase kickback
forces and increase the risk of kickback
