KICKBACK

WARNING: Avoid kickback which

can result in serious injury . Kickback is the

backward,upwardorsuddenforwardmotion

of the guide bar occurring when the saw

chainnear theuppertip oftheguidebarcon-

tacts any object such as a log or branch, or

when the wood closes in and pinches the

saw chaininthecut.Contactingaforeignob-

ject in the wood can also result in loss of

chain saw control.

S Rotational Kickback canoccurwhenthe

moving chain contacts an objectat theup-

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

result is a lightning fast, reverse reaction

which kicks the guide bar up and back to-

ward the operator.

S Pinch-Kickback can occur when the the

wood closes in and pinches the moving

saw chain in the cut along the top of the

guide bar and the saw chain is suddenly

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.

S Pull-In can occur when the moving chain

contacts aforeignobjectin thewood inthe

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:

S Be extremely aware of situations or ob-

structions thatcan causematerial topinch

the top of or otherwise stop the chain.

S Do not cut more than one log at a time.

S Do not twist the saw as the bar is with-

drawn from an undercut when bucking.

Avoid Pull--In:

S Always begincutting with theengineat full

speed and thesaw housing against wood.

S Use wedges made of plastic or wood.

Never use metal to hold the cut open.

REDUCETHECHANCEOF

KICKBACK

S Recognize that kickback can happen.

With a basic understanding of kickback,

you can reduce the element of surprise

which contributes to accidents.

S Never letthemovingchaincontactanyob-

ject at the tip of the guide bar.

S Keep the working area free from obstruc-

tionssuchas othertrees, branches,rocks,

fences, stumps, etc. Eliminate or avoid

any ob struction that your saw chain could

hit while you are cutting through a particu-

lar log or branch.

S Keep your saw chain sharp and properly

tensioned. A loose or dull chain can in-

crease the chance of kickback occurring.

Follow manufacturer’ s chain sharpening

andmaintenanceinstructions. Check ten-

sion at regular intervals with the engine

stopped, never with the engine running.

Makesurethebarclampnuts aresecurely

tightened after tensioning the chain.

S Begin and continue cutting at full speed. If

the chain is moving at a slower speed, there

is greater chance of kickback occurring.

S Cut one log at a time.

S Use extreme caution when re-entering a

previous cut.

S Do not attempt cuts starting with the tip of

the bar (plunge cuts).

S Watch for shifting logs or other forces that

could close a cut and pinch or fall into chain.

S Use the Reduced--Kickback Guide Bar and

Low--Kickback Chain specified for your saw.

MAINTAIN CONTROL

Never reverse
