SAFETY RULES

OPERATE YOUR SAW SAFELY

- Do not operate a chain saw with one hand, Serious injuryto the operator, heipers, bystanders or any com-

bination of these persons may result from one-hand- ed operation. A chain saw is intended for two-handed

use,

• Operate the chain saw only in well-ventilated out- door areas.

• Do not operate saw from a ladder or in a tree, unless specifically trained to do so,

• Position all parts of your body to the left of cut and away from the chain when the engine is running.

• Cut wood only. Do not use your saw to pry or shove away limbs, roots, or other objects.

° Make sure the chain will not make contact with

any object while starting the engine. Never try to

start the saw when the guide bar is in a cut or kerr.

• Use extreme caution when cutting small size brush and saplings. Slender material can catch the

chain and be whipped toward you or pull you off bal- ance,

• Be alert for springback when cutting a limb that is under tension so you will not be struck by the limb or

saw when the tension in the wood fibers is released.

° Do not put pressure on the saw at the end of a cut°

Applying pressure can cause you to losecontrol when the cut is completed.

- Stop the engine before setting the saw down,,

- Keep fuel and oil caps, screws, and fasteners securely

tightened,

GUARD AGAINST KICKBACK - Kickback is a dangerous reaction that can lead to serious injury.

KICKBACK WARNING

KICKBACK CAN OCCUR WHEN THE MOV-

ING CHAIN CONTACTS AN OBJECT ATTHE UPPER PORTION OF THE TIP OF THE

GUIDE BAR OR WHEN THE WOOD CLOSES IN AND PINCHES THE CHAIN IN THE CUT.

CONTACT AT THE UPPER PORTION OF THE TIP OF THE GUIDE BAR 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. IF THE CHAIN IS

PINCHED ALONG THE TOP OF THE GUIDE BAR, THE GUIDE BAR CAN BE DRIVEN

RAPIDLY BACK TOWARD THE OPERATOR. EITHER OF THESE REACTIONS CAN

CAUSE LOSS OF SAW CONTROL WHICH CAN RESULT IN SERIOUS INJURY. DO NOT RELY ONLY ON THE SAFETY DEVICES PROVIDED WITH YOUR SAW. AS A CHAIN

SAW USER, YOU USER, YOU MUST TAKE SPECIAL SAFETY PRECAUTIONSTO HELP

KEEP YOUR CUTTING JOBS FREE FROM ACCIDENT OR INJURY.

MAINTAIN CONTROL

• Keep a good, firm grip on the saw with both hands when the engine is running and don't let go. Figure4

A firm grip can neutralize kickback and help you maintain control of the saw Keep the fingers of your left hand

encirclingand 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 han- dle when making bucking cuts. Figure 4. Never

reverse rightand left hand positionsforany type of cut- ling

• Stand with your weight evenlybalanced on both feet,

° Stand slightly to the left side of the saw to keep your

body from being in a direct line with the cutting chain, Figure 4

• Do not overreach. You could be drawn or thrownoff bal- ance and lose controlof the saw

• Do not cut above shoulder height, It is difficult to maintain controlof saw above shoulder height.

UNDERSTANDING REACTIVE FORCES

Pinch-Kickback and Putt-ln occur when the chain is suddenly stopped by being pinched, caught, or by con-

tacting a fore=gn object in the wood. Thisstopping ofthe

chain results in a reversal of the chain force usedto cut

woodand causesthesaw to move in the oppositedirection

of the chain rotation Either reaction can result in toss of control and possibleserious injury.

• Pinch-Kickback

- occurs when chain on top of guide bar is suddenly

stopped

- rapidly drives saw straight back toward operator_

° Pull-In

- occurs when the chain on the bottom of the guide bar

is suddenly stopped

- pulls the saw rapidly forward

demonstrated to significantly reduce the number and seriousness of kickbacks when tested in accordance with ANSI B1751-1991

• Low-Kickback Chain, designed with acontoured depth gauge and guard link which detlect kickback force and allow wood to gradually ride into

the cutter Figure 5 Low-Kickback Chain is chatn which has met kickback performance requirements of ANSi B175 1-1991 when tested

on a representative sample of chain saws below 38 cubic inch dis-

placement specilied in ANS_ B175 1-199I

THE FOLLOWING FEATURES ARE INCLUD*

ED ON YOUR SAW TO HELP REDUCE THE HAZARD OF KICKBACK; HOWEVER, SUCH

FEATURES WILL NOT TOTALLY ELIMINATE

THIS DANGEROUS REACTION. AS A CHAIN
