GUIDE BAR MAINTENANCE
When the guide bar shows signs of wear, reverse it 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.
◾ ◾
Wear inside the bar rails which permits the chain to lay over sideways.
◾ ◾
Bent guide bar.
◾ ◾
Cracked or broken rails.
◾ ◾
Spread rails.
In addition, the guide bar has a sprocket
at its tip. The sprocket must be lubricated
weekly with a grease syringe to extend
the guide bar life. Use a grease syringe to
lubricate weekly with chain oil by means of
the lubricating hole (Fig. 37). Turn the guide
bar and check that the lubrication holes
and chain groove are free from impurities.
