3 You can also use the chain brake as a temporary brake when you change position or if you put the saw down for a short time. You should also apply the chain brake manually if there is a risk of the chain accidentally hitting anyone or anything close by. 4 To release the chain brake pull the front hand guard backwards, towards the front handle. 5 As mentioned in section A, kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw firmly and not let go. English – 5 SAFETY INSTRUCTIONS The way the chain brake is triggered, either manually or automatically, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake will be activated by the movement of the counterweight (INERTIA ACTIVATED). If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand. During felling your left hand grasps the front handle in such a way that it cannot activate the front hand guard. In this position the chain brake can only be activated by the inertia action of the counterweight. The inertia activated chain brake increases your safety but there are certain factors to remember (see point 6 above). 2 Throttle lock The throttle lock 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 trigger (B). When you release the handle the throttle trigger and the throttle lock both move back to their original positions. This movement is controlled by two independent return springs. This arrangement means that the throttle control is automatically locked at the idle setting when you release the handle. 3 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 section on ”Assembly”) and if the bar and chain are properly serviced and maintained. (See section on ”General working instructions”). 4 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. A B 6 – English SAFETY INSTRUCTIONS 5 Vibration damping system Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations and make operation easier. When you use a chain saw vibrations are generated by the uneven contact between the chain and the wood you are cutting. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with a chain that is blunt or faulty (wrong type or badly sharpened, see section D) will increase the vibration level. The vibration damping system reduces the vibrations transmitted from the engine and chain to the handles of the chain saw. The body of the saw, including the cutting equipment, is insulated from the handles by vibration damping units. ! 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. These 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. 6 Stop switch Use the stop switch to switch off the engine. 7 Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. ! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the saw indoors or near combustible material! In countries with a hot climate there is a high risk of forest fires. Our chain saws are therefore fitted with a SPARK ARRESTOR MESH. Check whether your saw is fitted with such a mesh. With this type of muffler it is very important that you follow the instructions on checking, maintaining and servicing your saw (see the section on ”Inspecting, maintaining and servicing chain saw safety equipment”). ! The muffler gets very hot in use and remains so for a short time afterwards. DO NOT TOUCH THE MUFFLER IF IT IS HOT! English – 7 SAFETY INSTRUCTIONS Inspecting, maintaining and servicing chain saw safety equipment ! ! SPECIAL TRAINING IS REQUIRED to service and repair chain saws. This is especially true of chain saw safety equipment. If your chain saw fails any of the checks described below take it to your SERVICE AGENT. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your saw is not a SERVICING DEALER, ask him for the address of your nearest SERVICE AGENT. 1 Chain brake and front h...
