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.
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
possible that the chain brake does not stop the saw
chain before it touches you. There are also some
positions in which your hand can not touch the front
hand guard to engage the chain brake.
• Will the inertia release mechanism always engage
the chain brake during kickback?
No. First, the chain brake must operate correctly.
To do a check of the chain brake on page
Refer to
23 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.
