2.4. 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 tool misuse and/or incorrect op-
erating procedures or conditions and can be avoided by
taking proper precautions as given below:
1.
Maintain a firm grip, with thumbs and fingers en-
circling the chain saw handles, with both hands
on the saw and position your body and arm to al-
low you to resist kickback forces. Kickback forces
can be controlled by the operator, if proper precau-
tions are taken. Do not let go of the chain saw.
Do not overreach and do not cut above shoul-
2.
der height. This helps prevent unintended tip con-
tact and enables better control of the chain saw in
unexpected situations.
3.
Only use replacement bars and chains specified
by the manufacturer. Incorrect replacement bars
and chains may cause chain breakage and/or kick-
back.
4.
Follow the manufacturer's sharpening and main-
tenance instructions for the saw chain. Decreas-
ing the depth gauge height can lead to increased
kickback.
