(For example, if improper tools are used to remove the flywheel, or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and could subsequently cause the flywheel to burst.) Throughout this manual are special “Attention Statements”. CAUTION! A statement preceded by the word “CAUTION” contains information that should be acted upon to prevent mechanical damage. NOTE: A statement preceded by the word “NOTE” contains information that is handy to know and may make your job easier. IMPORTANT! A statement preceded by the word “IMPORTANT” is one that possesses special significance. Do not operate this tool if you are tired, ill or under the influence of alcohol, drugs, or medicine. 3 WARNING! Chain saws can be dangerous! Careless or improper use can result in serious or fatal injury to the operator or others. Read and follow the Operator’s Manual. Failure to do so could result in serious injury. Wear eye and hearing protec- tion at all times during the oper- ation of this unit. Always hold the saw with both hands. Beware of Kickback! Kickback can occur whenever the tip of the guide bar touches an object while the saw is operating. Kickback may force the bar up and back toward the opera- tor with a lightning-fast reaction! Never let the guide bar tip come in contact with any object. Pinching the saw along the top of the guide bar may force the bar rapidly back toward the operator. Pinching can occur whenever wood closes in around the moving chain.

Chain Brake Your chain saw is equipped with a chain brake that is designed to stop the chain in the event of a kickback. The chain brake reduces the risk of acci-dents, but only you can prevent them. The chain brake can be activated manu- ■ ■ ally by your left hand pushing against the hand guard or automatically by the inertia release mechanism, in the event of kickback, stopping the saw chain. Activating the chain brake tightens ■ ■ a brake band around the chain drive mechanism, stopping the chain rotation. NOTE: The function of the front hand guard is to reduce the risk of the chain hitting your left hand if you loose the grip of the front handle. Either of the following reactions could cause you to lose control of your saw while cutting, possibly resulting in serious injury! Kickback can occur whenever the guide 1. bar nose or tip contact an object while the saw is running. Tip contact may cause the guide bar to kick upward and back toward the operator with a light- ning-fast reaction! Pinching the saw along the top of the 2. guide bar may push the guide bar rap- idly back toward the operator! Pinch- ing can occur whenever wood closes in around the moving chain! Do not rely exclusively on the safety devices incorporated with your saw. As a chain saw user, observing the following steps will also help you to avoid accident or injury on the job: Sudden surprise can contribute to ■ ■ accidents! With a basic understanding of kickback, you can reduce or elimi- nate the element of surprise. Clear obstructions from the work area ■ ■ before cutting. Remove any log, branch, or other obstruction that might contact the guide bar tip during cutting opera- tions.Grip the saw firmly with your right hand on the rear handle and your left hand on the front handle, thumbs and fingers encircling the handles whenever the saw is running. Don’t let go: A firm grip will help you to reduce kickback while maintaining control of the saw. Accelerate the saw before the chain ■ ■ contacts the work area, and always maintain high engine speeds through- out the cut. Do not overreach or attempt to cut ■ ■ above shoulder height. Follow the manufacturer’s instructions ■ ■ for sharpening and maintenance of the saw chain. Use only the replacement bar and ■ ■ chain combinations specified by the manufacturer. Never stand directly over the saw ■ ■ while cutting! Use low-kickback chain, chain brakes, ■ ■ or special guide bars to reduce the risk of kickback. Low kickback chain is chain that has met the kickback performance requirements of ANSI B175.1-2000 (American National Standard for Power Tools-Gasoline Powered Chain Saws- Safety Requirements) when tested on the representative sample of chain saws below 3.8 c.i.d. specified in ANSI B175.1-2000. Kickback Safety Precautions WARNING! Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback! Only use the bar and chain combinations recommended in the “Specifications” section. WARNING! Brake engagement and oper-ation depend upon proper chain brake condition! See “Chain Brake Testing” for procedures.. Cutting Equipment Guide bar. ■ ■ The smaller the guide bar tip radius the lower the chance of kickback. Low kick chain. ■ ■ Low kickback chain is designed to reduce the force of a kickback. CHN-16
