Stand on the left side of the trunk. Maintain a secure footing and In the carburetor, fuel is mixed with air. When the engine is test run at rest the saw on the trunk. Hold the saw close to you so that you are in full control of it. Keep well away from the chain. Move only when the factory, the carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one G the trunk is between you and the chain. Watch out for spring back of adjustment possibility: B limbs under tension. T = Idle speed adjustment screw. LIMBING THICK BRANCHES Idle speed adjustment (T) When limbing thick branches, the guide bar may get pinched easily. Check that the air filter is clean. When the idle speed is correct, the Branches under tension often snap up, so cut troublesome branches cutting attachment will not rotate. If adjustment is required, close D in small steps. Apply the same principles as for cross cutting. Think (clockwise) the T-screw, with the engine running, until the cutting E ahead and be aware of the possible consequences of all your attachment starts to rotate. Open (counter-clockwise) the screw actions. until the cutting attachment stops. You have reached the correct idle CROSS CUTTING/BUCKING Before starting to cut through the log, try to imagine what is going to happen. Look out for stresses in the log and cut through it in such a manner that the guide bar will not get pinched. 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. F R WARNING CROSS CUTTING LOGS, PRESSURE ON TOP When the engine is idling the cutting attachment must under no Take a firm stance. Begin with an upper cut.

THICK LOG, LARGER THAN GUIDE BAR LENGTH ○ Hard running conditions (such as cold weather). Begin by cutting on the opposite side of the log. Pull the saw towards These factors cause deposits on the spark plug electrodes, which you, followed by previous procedure. Make a boring cut if the log is may result in malfunction and starting difficulties. If the engine is close to the ground. Finish with a top cut. (Fig. 26) low on power, difficult to start or runs poorly at idling speed, always 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. 27) check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Readjust if necessary. The correct gap is 0.6 mm. The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded. NOTE In some areas, local law requires using a resistor spark plug IF THE SAW GETS STUCK to suppress ignition signals. If this machine was originally Stop the engine. Raise the log or change its position, using a thick equipped with resistor spark plug, use same type of spark plug branch or pole as a lever. Do not try to pull the saw free. If you do, for replacement. you can deform the handle or be injured by the saw chain if the saw is suddenly released. Oiler port (Fig. 31) Clean the chain oiler port (36) whenever possible. 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. 28) WARNING Never start the engine without the complete clutch cover. Otherwise the clutch can come loose and cause personal injuries. Guide bar (Fig. 32) Before using the machine, clean the groove and oiler port (37) in the bar with the special gauge offered as an optional accessory. Side case (Fig. 33) Always keep the side case and drive area clean of saw dust and debris. Periodically apply oil or grease to this area to protect from corrosion as some trees contain high levels of acid. 13
