als. Use of the chain saw for operations dif-
ferent than intended could result in a hazard-
ous situation.
■
Do not attempt to fell a tree until you have
an understanding of the risks and how to
avoid them. Serious injury could occur to the
operator or bystanders while felling a tree.
■
Follow all instructions when clearing
jammed material, storing or servicing the
chain saw. Make sure the switch is off and
the battery pack is removed. Unexpected
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 fin-
gers 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 precau-
tions are taken. Do not let go of the chain
saw.
■
Do not overreach and do not cut above
shoulder height. This helps prevent unin-
tended 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. In-
correct 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.
