S Once a year, replace the spark plug, air filter, and check guide bar and chain for wear. A new spark plug and air filter assures proper air-fuel mixture and helps your engine run better and last longer. CHECK FOR DAMAGED OR WORN PARTS Contact an authorized service dealer for replacement of damaged or worn parts. NOTE: It is normal for a small amount of oil to appear under the saw after engine stops. Do not confuse this with a leaking oil tank. S ON/STOP Switch -- Ensure ON/STOP switch functions properly by moving the switch to the STOP position. Make sure engine stops; then restart engine and continue. S Fuel Tank -- Do not use saw if fuel tank shows signs of damage or leaks. S Oil Tank -- Do not use saw if oil tank shows signs of damage or leaks. CHECK FOR LOOSE FASTENERS AND PARTS S Bar Nuts S Chain S Muffler S Cylinder Shield S Air Filter S Handle Screws S Vibration Mounts S Starter Housing S Front Hand Guard CHECK CHAIN SHARPNESS A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING. CHECK GUIDE BAR Conditions which require guide bar maintenance: S Saw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to bar/chain. Check the condition of guide bar each time chain is sharpened. A worn guide bar will damage the chain and make cutting difficult. After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole. To maintain guide bar: S Move ON/STOP switch to STOP. S Loosen and remove bar nuts and clutch cover. Remove bar and chain from saw. 14
