Tip contact in some cases may cause a
sudden reverse reaction, kicking the guide
bar up and back towards the operator.
Pinching the saw chain along the top of the
guide bar may push the guide bar rapidly
back towards the operator.
Either of these reactions may cause you
to lose control of the saw, which could
result in serious personal injury. Do not rely
exclusively upon the safety devices built into
your saw. As a chain saw user, you should
take several steps to keep your cutting jobs
free from accident or injury.
Kickback is the result of chain saw misuse
and/or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions as given below:
•
Maintain a rm grip, with thumbs and
ngers encircling the chain saw handles,
with both hands on the saw and position
your body and arm to allow you to
resist kickback forces.
Kickback forces
can be controlled by the operator, if proper
precautions are taken. Do not let go of the
chain saw.
•
Do not overreach and do not cut above
shoulder height.
This helps prevent
unintended tip contact and enables better
control of the chain saw in unexpected
situations.
•
Only use replacement guide bars and saw
chains specied by the manufacturer.
Incorrect replacement guide bars and saw
chains may cause chain breakage and/or
kickback.
•
Follow the manufacturer’s sharpening
and maintenance instructions for the saw
chain.
Decreasing the depth gauge height
can lead to increased kickback.
KICKBACK SAFETY DEVICES ON
THIS CHAIN SAW CHAIN
Brake
The chain saw comes equipped with a chain
brake, which stops both the motor and
the motion of the chain when kickback occurs.
The chain brake can be activated by the forward
motion of the chain-kickback brake handle as
the saw rotates backward during kickback; it can
also be activated by the inertial forces generated
during rapid pushback.
WARNING
! Never modify or attempt to
disable the chain brake.
Make sure that the chain brake is working
properly before using the chain saw. The chain-
kickback brake handle should move back and
forth easily.
To test the operation of the chain brake perform
the following steps (Fig. 1):

•
Place the chain saw on a at bare surface
and make sure no objects or obstructions
that could come in contact with the bar and
chain are in the immediate vicinity.
•
Disengage the chain brake by pulling the
chain-kickback brake handle towards the
front handle.
•
Start the chain saw.
•
Push the chain-kickback brake handle
towards the front of the saw. A properly
functioning hand brake will stop the
movement of the chain immediately. If the
chain brake is not working properly, do not
use the chain saw until it has been repaired
by a qualied service technician.
WARNING
: Conrm that the chain brake
works properly before each use.
