MAINTENANCE
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.
