English THICK LOG, LARGER THAN GUIDE BAR LENGTH Begin by cutting on the opposite side of the log. Pull the saw towards you, followed by previous procedure. (Fig. 27) THICK LOG, LARGER THAN GUIDE BAR LENGTH Begin by cutting on the opposite side of the log. Pull the saw towards you, followed by previous procedure. Make a boring cut if the log is close to the ground. Finish with a top cut. (Fig. 30) 2 ... Fig. 27 If the log is lying on the ground make a boring cut to avoid cutting into the ground. Finish with a bottom cut. (Fig. 28) ....... .....r Fig. 30 O 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. 31) 3 -*- 3 Fig. 28 pi 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. CROSS CUTTING LOGS, PRESSURE ON BOTTOM Take a firm stance. Begin with a bottom cut. The depth of the cut should be about 1/3 of the log diameter. Finish with an upper cut. The saw cuts should meet. (Fig. 29) 31 30 U.) .... ..... -► 2 Fig. 31 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. 29 33 Fig. 29 29. Relieving cut 30. Cross cut 31. Pressure on bottom 32. Tension side 33.

Carburetor adjustment (Fig. 32) LI Fig. 32 WARNING Never start the engine without the complete side case. Otherwise the clutch can come loose and cause personal injuries. 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 Some models sold in areas with strict exhaust emission regulation do not have high and low speed carburetor adjustments. Such adjustments may allow the engine to be operated outside of their emission compliance limits. For these models, the only carburetor adjustment is idle speed. If you are not familiar with this type of adjustment, please ask for assistance from your Tanaka dealer. Air filter (Fig. 33) The air filter (37) and cleaner sponge (36), (38) must be cleaned from dust and dirt in order to avoid: O Carburetor malfunctions. O Starting problems. O Engine power reduction. O Unnecessary wear on the engine parts. O Abnormal fuel consumption. Clean the air filter daily or more often if working in exceptionally dusty areas. Cleaning the air filter Remove the air filter cover (35) and the cleaner sponge (36). Turn the air filter (37) 20° counter-clockwise and remove. Then remove the cleaner sponge (38). 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. 38 37 36 35 0 Fig. 33 Spark plug (Fig. 34) The spark plug condition is influenced by: O An incorrect carburetor setting. O Wrong fuel mixture (too much oil in the gasoline) O A dirty air filter. O Hard running conditions (such as cold weather). These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always 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 0.024" (0.6 mm). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded. 15
