NOTE: If chain is difficult to rotate on guide bar or if it binds, too much tension has been applied. This requires minor adjustment as follows: A. Loosen the bar retaining nut so it is finger tight. Decrease tension by turning the bar adjustment screw CLOCKWISE slowly. Move chain back and forth on bar. Continue to adjust until chain rotates freely, but fits snugly. Increase tension by turning bar adjustment screw COUNTERCLOCKWISE. B. When saw chain has proper tension, hold nose of bar in uppermost position and tighten the bar retaining nut securely. A CB Fig. 29 A new saw chainCAUTION: stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain, and the interval between future adjustments will lengthen quickly. If saw chain is TOO CAUTION: LOOSE or TOO TIGHT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Fig. 29 for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). CHAIN BRAKE MECHANICAL TEST The purpose of the WARNING: Chain Brake® is to reduce the possibility of injury due tokickback; however, it cannot provide theintended measure of protection if the saw isoperated carelessly. Always test the Chain Brake® before usingyour saw and periodically while on the job. Your chain saw is equipped with a Chain Brake® that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly. To Test the Chain Brake®: 1. The Chain Brake® is DISENGAGED (chain can move) when BRAKE LEVER IS PULLED BACK AND LOCKED (A, Fig. 24). 2. The Chain Brake® is ENGAGED (chain is stopped) when brake lever is in forward position. You should not be able to move chain (B, Fig. 30). NOTE: The brake lever should snap into both positions. If strong resistance is felt, or lever does not move into either position, do not use your saw. Take it immediately to a Authorized Service Center for repair. Call 1-800-520-5520 for more information. A B Fig. 30 MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE AND REPAIR INSTRUCTIONS AIR FILTER Never operate sawCAUTION: without the air filter. Dust and dirt wil be drawn into engine and damage it. Keep the air filter clean. 1. Remove the top cover (A) by loosening the cover retaining screws. Cover will lift off (Fig. 31). 2. Clean air filter. Wash filter in clean, warm, soapy water. Rinse in clear, cool water. Air dry completely. NOTE: It is advisable to have a supply of spare filters. 3. Install air filter.

To avoid serious WARNING: personal injury, always turn your unit off and allow it to cool before you clean or service it. B A Fig. 31 FUEL FILTER Never operate sawCAUTION: without the fuel filter. The fuel filter should be replaced after each 20 hours of use. Drain fuel tank before changing. 1. Remove air box cover and air filter as shown in Fig. 31. 2. Disconnect fuel hose (A) from carburetor fitting (Fig. 32). 3. Pull fuel filter (C) out of tank with a bent wire (D) or long needle nosed pliers. Disconnect filter and discard (Fig. 32). NOTE: Do not pull hose completely out of tank. 4. Install a new fuel filter on hose and pull hose/filter assembly back into tank so filter is positioned in front right corner. 5. Reconnect fuel hose (A) to carburetor fitting (B) (Fig. 32). Replace air filter and air box cover. 6. Fill tank with fresh fuel / oil mixture. See Oil and Fuel Information. Install fuel cap. A Fig. 32 B D C MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE AND REPAIR INSTRUCTIONS OIL FILTER NOTE: Drain oil tank before changing filter 1. Disconnect oil hose (A) from pump fitting (B) (Fig. 33). 2. Use a wire with a hook (C) and pull oil filter (D) from tank. Remove filter and hose completely. 3. Insert a length of hose into tank and pull it through filler opening 4. Install a new filter on hose and pull hose back into tank so filter is positioned in bottom of tank. 5. Cut hose to fit and push it on to oil pump fitting. D C A B Fig. 33 SPARK ARRESTER SCREEN NOTE: A clogged spark arrester screen will dramatically reduce engine performance. 1. Remove 2 muffler retaining nuts (E), Lock plate (F) and muffler cover(G) (Fig. 34). 2. Remove spark arrester screen (H) from the metal baffle (J). Replace screen with new one. 3. Reassemble the muffler components and tighten nuts securely. H G F E J Fig. 34 SPARK PLUG NOTE: For efficient operation of saw engine, spark plug must be kept clean and properly gapped. 1. Push STOP switch up. 2. Remove top Cover. Disconnect the wire connector from the spark plug by pulling and twisting at the same time (Fig. 35). 3. Remove spark plug with spark plug socket wrench.
