MAINTENANCE

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.

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.

NOTE: Do not replace the screw with an ordinary

screw. Use only identical replacement parts from

the manufacturer when replacing parts.
