Side Plate Angle (Fig. 34)
◾
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. 35. 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. 36). Depth-gauge
jointers are available in 0.020 in. to
0.035 in. (0.5 mm to 0.9 mm). Use a
0.25 in. (0.6 mm) depth-gauge
jointer.
Depth-gauges must be adjusted with
the flat file in the same direction the
