Depth Gauge Clearance
1. The depth gauge should be maintained at a
clearance of 0.025 in. (06 mm), as shown in Fig.
38. Use a depth gauge tool (available
separately) to check the depth gauge
clearances.
Check the depth gauge clearance every time
2.
the chain is filed.
Use a fiat file and a depth-gauge jointer (both
available separately) to lower all gauges uniformly
(Fig. 39). Depth-gauge jointers are available in
0.020 in. to 0.035 in. (0.5 mm to 0.9 mm). Use a
0.025 in. (0.6 mm) depth-gauge jointer.
Depth-gauges must be adjusted with the fiat file in
the same direction the adjoining cutter was filed
with the round file. Use care not to contact the
cutter face with the flat file 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
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. 40). Turn the
guide bar and check that the lubrication holes and
chain groove are free from impurities.
