MAINTENANCE MAINTAINING THE GUIDE BAR See Figure 47. WARNING: Before performing any maintenance, make sure the tool is unplugged from the power supply. Failure to comply could result in accidental starting and possible serious personal injury. Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage. Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur. A bar with any of the following faults should be replaced: 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 Lubricate guide bars weekly with a sprocket at their tip. Using a grease syringe, lubricate weekly in the lubricating hole. Turn the guide bar and check that the lubrication holes and chain groove are free from impurities. MOUNTING THE SAFE-T-TIP NOSE GUARD See Figures 48 - 49. n Disconnect chain saw from power supply. n Mount the SAFE-T-TIP on the bar nose. n Fit the locking rivet or tab in the recessed hole 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.

WARNING: Although the guide bar comes with a SAFE-TTIP antikickback device already installed, check the tightness of the mounting screw before each use to avoid possible serious personal injury. Use the following instructions to tighten the mounting screw of the nose guard. These are specially hardened screws. If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP before further operation. Page 27 - English
