MAINTAINING THE GUIDE BAR
(See Figure 47)
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 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 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.
