Depth gauges must be adjusted with the at le in the same direction the adjoining cutter was
led with the round le. Use care not to contact the cutter face with the at le when adjusting
depth-gauges.

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 le 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.
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. 38). 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 chain saw, following the section:
“
Replacing the Bar and Chain
”.
2. Remove the chain from the guide bar
and turn the guide bar over (Fig. 39). 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 chain saw and adjust the chain tension,
following the section: “
Replacing the Bar
and Chain
” and “
Adjusting the Chain
Tension
”.
