S Pinch-Kickback can occur when the wood

closes in and pinches the moving chain in

the cut along the top of the guide bar and the

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 pruner to move in the opposite

direction of the chain rotation. The pruner is

driven straight back toward the operator.

S 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

chain is suddenly stopped. This sudden stop-

ping pulls the pruner forward and away from

the operator and could easily cause the oper-

ator to lose control of the pruner .

REDUCE THE C HANCE OF

KICKBACK

S Recognize that kickback can happen. With

a basic understanding of kickback, you can

reduce the element of surprise which con-

tributes to accidents.

S Never let the moving chain contact any ob-

ject at the tip of the guide bar.

S Keep the working area free from obstructions

such as other trees, branches, rocks, stumps,

etc. Eliminate or avoid any obstruction that

your chain could hit while you are cutting.

When cutting a branch, do not let the guide

bar contact branch or other objects around it.

S Keep your chain sharp and properly ten-

sioned. A loose or dull chain can increase

the chance of kickback occurring. Follow

manufacturer’s chain sharpening and

maintenance instructions. Check tension at

regular intervals, but never with the motor

running. M ake sure the bar clamp nut is se-

curely 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 branch 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 of wood 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 unit.

MAINTAIN CONTROL

S Keep a good, firm grip on the pruner with both

hands when the unit is running and don’t let

go. A firm grip will help you reduce kickback

and maintain control. Keep the fingers of your

left hand encircling and your left thumb under

the assist handle. Keep your right hand com-

pletely around the trigger handle whether your

are right handed or left handed.

S Stand with your weight evenly balanced on

both feet.

S Stand slightly to the left side of the pruner to

keep your body from being in a direct line with

the cutting chain.

KICKBACK SAFETY FEATURES

WARNING: The following features

are included on your pruner to help reduce the

hazard of kickback; however, such features

will not totally eliminate this danger. As a

pruner user, do not rely only on safety de-

vices. You must follow all safety precautions,

instructions, and maintenance in this manual

to help avoid kickback and other forces which

can result in serious injury .

S Reduced--Kickback Guide Bar, designed with

a small radius tip which reduces the size of

the kickback danger zone on the bar tip.

flect kickback force and allow wood to gradu-

ally ride into the cutter. A low kickback chain

has met kickback performance requirements

when tested on the representative sample of

the chain saws specified in ANSI B175.1.
