Kickback information
WARNING:
serious injury or death to the operator or
others. To decrease the risk you must know
the causes of kickback and how to prevent
them.
A kickback occurs when the kickback zone of the guide
bar touches an object. A kickback can occur suddenly
and with large force, which throws the product in the
direction of the operator.
(Fig. 48)
Kickback always occurs in the cutting plane of the guide
bar. Usually, the product is thrown against the operator
but can also move in a different direction. It is how you
use the product when the kickback occurs that causes
the direction of the movement.
(Fig. 49)
A smaller bar tip radius decreases the force of the
kickback.
Use a low kickback saw chain to decrease the effects of
kickback. Do not let the kickback zone touch an object.
WARNING:
prevents kickback. Always obey the
instructions.
Common questions about kickback
• Will the hand always engage the chain brake during
a kickback?
No. It is necessary to use some force to push the
front hand guard forward. If you do not use the force
necessary, the chain brake will not be engaged. You
must also hold the handles of the product stable with
two hands during work. If a kickback occurs, it is

positions in which your hand can not touch the front
hand guard to engage the chain brake.
• Will the inertia release mechanism always engage

Maintenance and checks of the safety
Refer to
devices on the product on page 32 for instructions
about how to do a check of the chain brake. We
recommend you to do this each time before you use
the product. Second, the force of the kickback must
be large to engage the chain brake. If the chain
brake is too sensitive, it can engage during rough
operation.
• Will the chain brake always protect me from injury
during a kickback?
No. The chain brake must operate correctly to give
protection. The chain brake must also be engaged
during a kickback to stop the saw chain. If you are
near the guide bar, it is possible that the chain brake
does not have time to stop the saw chain before it
hits you.
WARNING:
working technique can prevent kickbacks.
