Important Safety Instructions
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 chainsaw 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:
Maintain a firm grip, with thumbs and fingers
encircling the chainsaw 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 chainsaw.
Do not overreach and do not cut above
shoulder height. This helps prevent
unintended tip contact and enables better
control of the chainsaw in unexpected
situations.
Only use replacement bars and chains
specified by the manufacturer. Incorrect
replacement bars and 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.
Kickback Safety Devices
on This Saw
DANGER: NEVER MODIFY OR ATTEMPT
TO DISABLE THE CHAIN BRAKE.
DANGER: ONLY USE REPLACEMENT
BARS AND CHAINS SPECIFIED BY
Oregon®. Incorrect replacement bars and
chains may cause chain breakage and
increased risk of kickback injury.
CHAIN BRAKE
This chainsaw comes equipped with a chain
brake, which stops both the motor and the
motion of the chain when kickback occurs
(Fig. ). The chain brake can be activated by
the forward motion of the front hand guard as
the saw rotates backward during kickback; it
can also be activated by the inertial forces
generated from a kickback event.
CHAIN
This saw comes equipped with a saw chain
that met the reduced kickback requirements of
ANSI B. when tested on a representative
sample of chainsaws. For replacement chain,
see “Specifications and Components” in this
manual.
BAR
This saw comes equipped with a reduced
kickback guide bar that has a small radius nose.
Smaller radius noses have less potential for
kickback than a bar of the same size with a
larger nose radius.
When replacing the bar, only order the bar
listed in this manual to maintain low kickback
performance.
