MAINTAINING THE GUIDE BAR
See Figure 58.
CAUTION:
Make sure the chain has stopped before you
do any work on the saw.
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 pro-
cess 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:
 Wear inside the bar rails that permits the chain
to lay over sideways
 Bent guide bar
 Cracked or broken rails
 Spread rails
Lubricate guide bars with a sprocket at their tip
weekly. 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
GUARD
See Figures 59 - 60.
 Stop the engine and disconnect the spark plug
wire.
 Mount the SAFE-T-TIP
 Fit the locking tab in the recessed slot in the
guide bar.
 Tighten the mounting screw with wrench until
snug.
 From the snug position, tighten the mount-
ing screw an additional 3/4 of a turn using a
wrench.
