S A good, firm grip on the saw with both hands will help you maintain control. Don’t let go. Grip the rear handle with your right hand whether you are right or left handed. Wrap the fingers of your left hand over and around the front handle- bar, and your left thumb under the front handlebar. Keep your left arm straight with the elbow locked.

S 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. Stand slightly to the left side of the saw to keep your body from being in a direct line with the cutting chain.

S Stand with your weight evenly bal- anced on both feet.

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

SDo not cut above shoulder height. It is difficult to maintain control of saw above shoulder height.

KICKBACK SAFETY FEATURES

WARNING: The following features are included on your saw to help reduce hazard of kickback; however, such fea- tures will not totally eliminate this dan- ger. Do not rely only on safety devices. S Hand Guard: designed to reduce the

chance of your left hand contacting the chain if your hand slips off the front handlebar.

SPosition of front and rear handlebars: designed with distance between han- dles and “in-line” with each other. The spread and “in-line” position of the hands provided by this design work to- gether to give balance and resistance in controlling the pivot of the saw back toward the operator if kickback oc-

curs.

S Reduced-Kickback Guide Bar: de- signed with a small radius tip which re- duces the size of the kickback danger zone on the bar tip. This type bar has been demonstrated to significantly re- duce the number and seriousness of kickbacks when tested in accordance with ANSI B175.1.

WARNING: Computed Kickback Angle (CKA) listed on your saw and listed in the following CKA Table represents the angle of kickback your bar and chain combinations will have when tested in ac- cordance with CSA and ANSI standards. Computed angles represented in the CKA column indicate total energy and angle associated without a chain brake. When purchasing replacements, considerations should be given to the lower CKA values. In all cases, lower CKA values represent a safer operating environment for the user.

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

erator.

SPinching the saw chain along the tip of

the guide bar may push the guide bar rapidly back towards the operator.

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

The following guide bar and chain com- binations meet kickback requirements of CSA Z62.1 & Z62.3 and ANSI B175.1 when used on saws listed in this manual. Use of bar and chain combinations other than those listed is not recommended and may not meet the CKA requirements per standard.
