First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment.We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance. Will my chain brake always protect me from injury in the event of a kickback? No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain.Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger. Throttle lockout The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting. Chain catcher The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions). Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. 10 – English GENERAL SAFETY PRECAUTIONS Vibration damping system Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier. The machine.s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine.s handle unit.The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. ! WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the fingers, hands or wrists. These symptoms may be increased in cold temperatures. Stop switch Use the stop switch to switch off the engine. Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. ! WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! In areas with a hot, dry climate there is a high risk of fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor screen. CAUTION! The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours. ! WARNING! Never use a saw without a muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen. Cutting equipment This section describes how to choose and maintain your cutting equipment in order to: • Reduce the risk of kickback. • Reduce the risk of the saw chain breaking or jumping off the bar. • Obtain optimal cutting performance. • Extend the life of cutting equipment. • Avoid increasing vibration levels. General rules • Only use cutting equipment recommended by us! See instructions under the heading Technical data. • Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the English – 11 GENERAL SAFETY PRECAUTIONS recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback. • Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket. • Keep cutting equipment well lu...
