MAINTENANCE Proper maintenance will maximize the useful life of the guide bar. Each day of use: Clean the bar and check for wear and damage. Feathering or burring of the bar rails is a normal process of bar wear, but such faults should be smoothed with a file as soon as they occur. Each week of use: n Reverse the guide bar on the saw to distribute the wear. n Lubricate the socket at the end of the guide bar using a grease syringe in the lubricating hole. n Turn the guide bar and check that the lubrication holes and chain groove are free from impurities. A bar with any of the following faults should be replaced immediately: n Wear inside the bar rails that permits the chain to lay over sideways n Bent guide bar n Cracked or broken rails n Spread rails MOUNTING THE SAFE-T-TIP™ NOSE GUARD See Figures 58 - 59. n Stop the engine and disconnect the spark plug wire. n Mount the SAFE-T-TIP™ on the bar nose. n Fit the locking tab in the recessed slot in the guide bar. n Tighten the screw with wrench until snug. n From the snug position, tighten the screw an additional 3/4 of a turn using a wrench. MAINTAINING THE SAFE-T-TIP™ NOSE GUARD See Figures 58 - 59. CAUTION: Make sure the chain has stopped before you do any work on the saw.
