Depth-Gauge Clearance
1. The depth gauge should be
maintained at a clearance of 0.020"
(0.52 mm), as shown in Fig. 27. Use
a depth gauge machine (available
separately) to check the depth
gauge clearances.
2. Check the depth-gauge clearance
every time the chain is filed.
Use a flat file and a depth-gauge jointer
(both available separately) to lower all
gauges uniformly (Fig. 28). Depth-gauge
jointers are available from 0.020" to
0.035" (0.5 mm to 0.9 mm). Use a 0.020"
(0.52 mm) depth-gauge jointer.
Depth-gauges must be adjusted with
the flat 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 after use and be 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.
