2. SAFETY INSTRUCTIONS
Causes and operator prevention of kickback
3
0
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 operating
procedures or conditions and can be avoided by taking proper precautions
as given below:
1.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.
2.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.
3.Only use replacement guide bar and saw chains specified by
the manufacturer. Incorrect replacement bars and chains may cause
chain breakage and/or kickback.
4.Follow the manufacturer' s sharpening and maintenance
instructions for the saw chain. Decreasing the depth gauge height
can lead to increased kickback.
