Keep your left arm straight with the elbow

locked.

SPosition your left hand on the front handle- bar 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.

SStand with your weight evenly balanced on

both feet.

SStand slightly to the left side of the saw to keep your body from being in a direct line

with the cutting chain.

SDo not overreach. You could be drawn or thrown off balance and lose control of the

saw.

SDo not cut above shoulder height. It is diffi- cult to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features are included on your saw to help reduce the hazard of kickback; however, such features will not totally eliminate this dangerous reac- tion. As a chain saw user, do not rely only on safety devices. 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.

SReduced--Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. A Reduced--Kickback Guide Bar has been demonstrated to significantly re- duce the number and seriousness of kick- backs.

S Handguard, designed to reduce the chance of your left hand contacting the chain if your hand slips off the front handle- bar.

SPosition of front and rear handlebars, de- signed with distance between handles and “in-line” with each other. The spread and “in-line” position of the hands provided by this design work together to give balance and resistance in controlling the pivot of the saw back toward the operator if kick- back occurs.

WARNING: DO NOT RELY UPON ANY OF THE DEVICES BUILT INTO YOUR SAW. YOU SHOULD USE THE SAW PROPERLY AND CAREFULLY TO AVOID KICKBACK. Reduced--kickback guide bars and low--kickback saw chains reduce the chance and magnitude of kickback and are recommended. Your saw has a low kick- back chain and bar as original equipment. Repairs on a chain brake should be made by an authorized servicing dealer. Take your unit to the place of purchase if purchased from a servicing dealer, or to the nearest au- thorized master service dealer.

STip contact in some cases may cause a lightning fast reverse REACTION, kicking the guide bar up and back toward the oper-

ator.

SPinching the saw chain along the top of the guide bar may push the guide bar rapidly

back toward the operator.

SEither of these reactions may cause you to lose control of the saw which could result in serious injury. Do not rely exclusively upon the safety devices built into your saw.

CHAIN BRAKE

SChain brake, designed to stop the chain in the event of kickback.

WARNING: Your chain saw is equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.

DO NOT ASSUME THAT THE CHAIN BRAKE WILL PROTECT YOU IN THE EVENT OF A KICKBACK.
