MAINTAINING THE GUIDE BAR
See Figure 52.
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 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 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 53 - 54.
 Disconnect chain saw from power supply.
 Mount the SAFE-T-TIP on the bar nose.
 Fit the locking rivet or tab in the recessed hole
in the guide bar.
 Tighten the screw with wrench until snug.
 From the snug position, tighten the screw an
additional 3/4 of a turn using a wrench.
