English Fig. 32 WARNING KICKBACK DANGER Do not attempt a boring cut if you are not properly trained. A boring cut involves the use of the nose of the guide bar and can result in kickback. (Fig. 33) Fig. 33 If the saw gets stuck Stop the engine. Raise the log or change its position, using a thick branch or pole as a lever. Do not try to pull the saw free. If you do, you can deform the handle or be injured by the saw chain if the saw is suddenly released. MAINTENANCE MAINTENANCE, REPLACEMENT OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEM MAY BE PERFORMED BY ANY NON-ROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL. Carburetor adjustment (Fig. 34) T In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility: T = Idle speed adjustment screw. Idle speed adjustment (T) Check that the air filter is clean. When the idle speed is correct, the cutting attachment will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the cutting attachment starts to rotate. Open (counter-clockwise) the screw until the cutting attachment stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the cutting attachment starts to rotate. If the cutting attachment still rotates after idle speed adjustment, contact Tanaka dealer. WARNING When the engine is idling the cutting attachment must under no circumstances rotate. NOTE Do not touch the High speed adjustment (H) and the Low speed adjustment (L). Those are only for Tanaka dealer. If you rotate them, it will cause a serious damage to the machine. Air filter (Fig. 35) The air filter (39) must be cleaned from dust and dirt in order to avoid: ○ Carburetor malfunctions. ○ Starting problems. ○ Engine power reduction. ○ Unnecessary wear on the engine parts. ○ Abnormal fuel consumption. Clean the air filter daily or more often if working in exceptionally dusty areas. Remove the air filter cover (40) and the filter (39). Rinse them in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced with a new one. A damaged filter must always be replaced. H L Fig. 34 15
