CAUTION! If the chain rotates while idling the T-screw must be turned anti-clockwise until the chain stops. Rec. idle speed: 2700 rpm Fine adjustment When the machine has been ”run-in” the carburetor should be finely adjusted. The fine adjustment should be carried out by a qualified person. First adjust the L- jet, then the idling screw T and then the H-jet. Conditions • Before any adjustments are made the air filter should be clean and the cylinder cover fitted. Adjusting the carburetor while a dirty air filter is in use will result in a leaner mixture next time the filter is cleaned. This can give rise to serious engine damage. • Do not attempt to adjust the L and H jets beyond either stop as this could cause damage. • Now start the machine according to the starting instructions and let it warm up for 10 minutes. • Place the machine on a flat surface so that the bar points away from you and so that the bar and chain do not come into contact with the surface or other objects. Low speed jet L Turn the low speed jet L clockwise until it stops. If the engine accelerates poorly or idles unevenly, turn the low speed jet L anticlockwise until good acceleration and idling are achieved. Fine adjustment of the idling speed T Adjust the idle speed with the T-screw. If it is necessary to re-adjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate.Then turn counterclockwise until the chain stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the chain starts to rotate. ! WARNING! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops at idle. Do not use the chain saw until it has been properly adjusted or repaired. High speed jet H At the factory the engine is adjusted at sea level. When working at a high altitude or in different weather conditions, temperatures and atmospheric humidity, it may be necessary to make minor adjustments to the high speed jet. 1153137-95 Rev.2 2009-12-29 English – 31 MAINTENANCE CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder. When test run at the factory, the high speed jet is set so that the engine satisfies the applicable legal requirements at the same time as achieving maximum performance. The carburetor’s high speed jet is then locked using a limiter cap in the fully screwed out position.The limiter cap limits the potential to adjust the high speed jet to at most half a turn. To adjust the carburetor correctly you should contact a mechanic with access to a rev counter. CAUTION! As the spark is cut off, the rev counter does not show speeds higher than 13600 rpm. Correctly adjusted carburetor When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difficulties and poor acceleration. If the H- jet is set too lean the machine will have less power, poor acceleration and could suffer damage to the engine. Checking, maintaining and servicing chain saw safety equipment Note! All servicing and repair work on the machine requires special training. This is especially true of the machine.s safety equipment. If your machine fails any of the checks described below we recommend you to contact our servicing dealer. Chain brake and front hand guard Checking brake band wear Brush off any wood dust, 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 0.024 inch (0.6 mm) thick at its thinnest point. Checking the front hand guard Make sure the front hand guard is not damaged and that there are no visible defects such as cracks. Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover. Checking the inertia brake release With the engine turned off, hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle. When the bar hits the stump the brake should be applied. 32 – English 1153137-95 Rev.2 2009-12-29 MAINTENANCE Checking the brake trigger Place the chain saw on firm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop. Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles. Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately. Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released. • Press the throttle lockout and make sure it retu...
