More user manuals on ManualsBase.com English – 3 ! Before using a new saw • Read the instructions carefully. • Check cutting equipment is correctly fitted and adjusted. See page 25. • Refuel and start the saw. Check the carburettor settings. See pages 26-29. • Do not use the saw until sufficient chain oil has reached the chain, see page 14. IMPORTANT! If the carburettor mixture is too lean it greatly increases the risk of engine failure. Poor maintenance of the air filter will cause carbon build-up on the spark plug and lead to difficult starting. If the chain is badly adjusted it will cause increased wear or damage to the bar, drive sprocket and chain. Under no circumstances should you modify the original design of the chain saw without approval from the manufacturer. Always use genuine spare parts. Unauthorized modifications or accessories may lead to serious injury or death.

More user manuals on ManualsBase.com English – 5 1 Chain brake and front hand guard 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. Take care when using your saw and make sure the kickback zone of the bar never touches any object. 1 The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism (a free- swinging pendulum). On most of our models the front hand guard acts as a counterweight in case of kickback. The brake is applied when the front hand guard (B) is pushed forwards. This movement activates a spring-loaded mechanism that tightens the Brake Band (C) around the engine drive system (D) (Clutch Drum). SAFETY INSTRUCTIONS 2 The front hand guard is not designed solely to activate the chain brake. Another important safety feature is that it prevents the chain from hitting your left hand if you lose your grip on the front handle. 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. A B B D B C

More user manuals on ManualsBase.com 6 – English 6 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. 7 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 SAFETY INSTRUCTIONS

More user manuals on ManualsBase.com English – 7 ! 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. SAFETY INSTRUCTIONS ! 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! ! The muffler gets very hot in use and remains so for a short time afterwards. DO NOT TOUCH THE MUFFLER IF IT IS HOT! 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. 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”).

Let go of the front handle so that the bar falls onto the stump. When the bar hits the stump the brake should be applied. 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 hand guard 1 Checking brake band wear Brush off any sawdust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake. Regularly check that the brake band is at least 0.6 mm thick at its thinnest point. SAFETY INSTRUCTIONS 4 Checking the brake trigger Start the chain saw and place it on firm ground. Make sure the chain does not touch the ground or any other object. Grasp the saw firmly, wrapping your fingers and thumbs around the handles. Apply full throttle and activate the chain brake by tilting your wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately. 2 Checking the front hand guard A Make sure the FRONT HAND GUARD is not damaged and that there are no visible defects such as cracks. B Move the front hand guard forwards and back to make sure it runs freely and that it is securely anchored to the clutch cover.

Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle is on idle setting you should check the carburettor idle adjustment. See the section on ”Maintenance”. 3 Chain catcher Check that the CHAIN CATCHER is not damaged and is firmly attached to the body of the saw.

If the muffler on your saw is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Never use a muffler if the spark arrestor mesh is missing or defective. NEVER USE A CHAIN SAW WITH FAULTY SAFETY EQUIPMENT. CARRY OUT THE CHECKS AND MAINTENANCE MEASURES DESCRIBED IN THIS SECTION. IF YOUR CHAIN SAW FAILS ANY OF THESE CHECKS CONTACT YOUR SERVICE AGENT TO GET IT REPAIRED. 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 chain breaking or jumping. • Obtain maximum cutting performance. • Extend the life of cutting equipment. The 5 basic rules 1 Only use cutting equipment recommended by us! See the ”Technical data” section. 2 Keep the chain cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents. 3 Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback. 4 Keep the chain properly tesioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket. 5 Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket. SAFETY INSTRUCTIONS
