 Make certain the saw chain stops moving when the

throttle trigger is released. For correction, refer to

 Never modify your saw in any way.

 Keep the handles dry, clean, and free of oil or fuel

mixture.

 Keep fuel and oil caps, screws, and fasteners

securely tightened.

 Use only genuine accessories and replacement

locale where such regulations exist, you are legally

responsible for maintaining the operating condition

of these parts. Failure to do so is a violation of

the law. Refer to the MAINTENANCE section for

maintenance of the spark arresting screen.

HANDLING FUEL

UNDERSTANDING KICKBACK

a WARNING! Avoid kickback which can result

in serious injury. Kickback is the backward,

upward or sudden forward motion of the

guide bar occurring when the saw chain near

the upper tip of the guide bar contacts 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 object in the

wood can also result in loss of chainsaw

control.

ROTATIONAL KICKBACK

Rotational kickback can occur when the moving chain

contacts an object at the upper 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 toward the operator.

PINCH KICKBACK

Pinch kickback can occur when 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 saw to move in the opposite direction of

the chain rotation. The saw is driven straight back

toward the operator.

PULL-IN

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 sudden stopping pulls the saw forward

and away from the operator and could easily cause

the operator to lose control of the saw.

REDUCING THE CHANCE OF

KICKBACK

 Recognize that kickback can happen. With a basic

understanding of kickback, you can reduce the

element of surprise which contributes to accidents.

 Never let the moving chain contact any object at the

tip of the guide bar.

 Keep the working area free from obstructions such

as other trees, 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 increase the chance of

kickback occurring. Follow manufacturer’s chain

sharpening and maintenance instructions. Check

tension at regular intervals with the engine stopped,

never with the engine running. Make sure the bar

nuts are securely tightened after tensioning the

chain.

 Begin and continue cutting at full speed. If the chain

is moving at a slower speed, there is greater chance

of kickback occurring.

 Use wedges made of plastic or wood. Never use

metal to hold the cut open.

 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

 Watch for shifting logs or other forces that could

close a cut and pinch or fall into chain.

 Do not twist the saw as the bar is withdrawn from an

undercut when bucking.

 Use the reduced-kickback guide bar and low-

hand encircling and your left thumb under the front

handlebar. Keep your right hand completely around

the rear handle whether you are right handed or left

handed. Keep your left arm straight with the elbow

locked.

 Position your left hand on the front handlebar so it

is in a straight line with your right hand on the rear

handle when making bucking cuts. Never reverse

right and left hand positions for any type of cutting.

 Stand with your weight evenly balanced on both feet.
