Causes and operator prevention of kickback.
Kickback may occur when the nose or tip of the
guide bar touches an object, or when the wood
closes in and pinches the saw chain in the cut.
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:
A.
Maintain a firm grip, with thumbs and
fingers 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.
B.
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.
C.
Only use replacement guide bars
and saw chains specified by the
manufacturer. Incorrect replacement guide
bars and saw chains may cause chain
breakage and/or kickback.
D.
Follow the manufacturer's sharpening
and maintenance instructions for the
saw chain. Decreasing the depth gauge
height can lead to increased kickback.
