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 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.
