MAINTAINING THE GUIDE BAR
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.
Chain specifications: 3/8 in. pitch, low profile narrow kerf, .043 in. chain gauge, 5-tooth drive sprocket.
