actuation of the chain saw while clearing jammed material or servicing may result in
serious personal injury.
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:
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.
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 specified 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.
Do not operate a chain saw in a tree unless you have been specifically trained to
•
do so . Operation of a chain saw in a tree without proper training could increase the risk of
serious personal injury.
