Side Plate Sharpening Angle
(Fig. 23)
◾ ◾
CORRECT 55°- The optimal angle
can be produced automatically if the
correct diameter file is used in the
file holder.
◾ ◾
HOOK- "Grabs" and dulls quickly.
Increases potential of KICKBACK.
Results from using a file with a
diameter that is too small, or a file held too low.
◾ ◾
BACKWARD SLOPE- Needs too much feed pressure, causes excessive wear to bar
and chain. Results from using a file with a diameter too large, or a file held too
high.
Depth-Gauge Clearance
1. The depth gauge should be
maintained at a clearance of 0.025
in. (0.6 mm), as shown in Fig. 24.
Use a depth-gauge tool (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. 25). Depth-gauge
jointers are available from 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
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.
