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. 25). Turn the guide
bar and check that the lubrication holes and chain groove are free from impurities.
Reversing the Guide Bar
1. Remove the guide bar and chain
from the pole saw, following the
section "REPLACING THE BAR AND
CHAIN".
2. Remove the chain from the guide
bar and turn the guide bar over
(Fig. 26). The bottom of the bar will
be on the top.
3. Replace the chain on the bar.
4. Reassemble the guide bar and chain on the pole saw and adjust the chain
tension, following the sections "REPLACING THE BAR AND CHAIN" and
"ADJUSTING THE CHAIN TENSION".
