KICKBACK

A

WARNING:

Avoid

kickback

which

can result in serious injury. Kickback is the
backward, upwardorsudden forward motion
of the guide bar occurring when the saw
chain nearthe uppertip oftheguide barcon-

tacts any object such as a log or branch, or
when the wood closes in and pinches the

saw chain in the cut. Contacting a foreign ob­

ject in the wood can also result in loss of

chain saw control.
• Rotational Kickback can occurwhenthe

moving chain contacts an object at the up­
per tip of the guide bar. This contact can
cause the chain to dig into the object,

which stops the chain for an instant. The

resuit is a iightning fast, reverse reaction

which kicks the guide bar up and back to­
ward the operator.

• Pinch-Kickbackcan occur when the the

wood cioses in and pinches the moving

saw chain in the cut along the top of the
guide bar and the saw chain is suddeniy
stopped. This sudden stopping of the
chain results in a reversal of the chain

force used to cut wood and causes the

sawtomoveintheoppositedirectionofthe
chain rotation. The saw is driven straight
back toward the operator.

Pull-In can occur when the moving chain

contacts a foreign object in the wood in the
cut along the bottom of the guide bar and

the saw chain is suddenly stopped. This

suddenstoppingpullsthesawforwardand
away from the operator and could easily
cause the operator to lose control of the
saw.

Avoid Pinch-Kickback:

• Be extremely aware of situations or ob­

structions that can cause material to pinch

the top of or otherwise stop the chain.

• Do not cut more than one iog at a time.
• Do not twist the saw as the bar is with­

drawn from an undercut when bucking.

Avoid Pull-In:

• Always begin cutting with the engineatfull

speed and the saw housing against wood.

• Use wedges made of plastic or wood.

Never use metal to hold the cut open.

REDUCE THE CHANCE OF
KICKBACK

Recognize that kickback can happen.

With a basic understanding of kickback,
you can reduce the eiement of surprise
which contributes to accidents.

• Never let the moving chain contact any ob­

ject at the tip of the guide bar.

* Keep the working area free from obstruc-

tionssuchas othertrees, branches, rocks,

fences, stumps, etc. Eliminate or avoid

any obstruction that your saw chain could
hit while you are cutting. When cutting a
branch, do not let the guide bar contact
branch or other objects around it.

* Keep your saw chain sharp and properly

tensioned. A loose or dull chain can in­
crease the chance of kickback occurring.
Foliow manufacturer’s chain sharpening
andmaintenanceinstructions. Check ten­
sion at regular intervals with the engine
stopped, never with the engine running.
Make sure the barclamp nuts are securely
tightened after tensioning the chain.

• Begin and continuecutting atfull speed. If

the chain is moving at a slower speed,
there is greaterchance of kickback occur­
ring.

• Cut one log at a time.
* Use extreme caution when re-entering a

previous cut.

* Do not attempt cuts starting with the tip of

the bar (plunge cuts).

• Watch for shifting logs or otherforces that

could close a cut and pinch or fall into
chain.

* Use the Reduced-Kickback Guide Bar

and Low-Kickback Chain specified for
your saw.
