CARE AND MAINTENANCE
Side Plate Angle (Fig. 13f)
CORRECT 55°- The optimal angle can be
produced automatically if the correct diameter le is
used in the le holder.
HOOK- “Grabs” and dulls quickly. Increases
potential of KICKBACK. Results from using a le
with a diameter that is too small, or a le held too
low.
BACKWARD SLOPE- Needs too much feed
pressure, causes excessive wear to bar and chain.
Results from using a le with a diameter too large,
or a le held too high.
Depth-Gauge Clearance
a. The depth gauge should be maintained at a
clearance of 0.025 in. (0.6 mm), as shown in
Fig. 13g. Use a depth gauge tool (available
separately) to check the depth gauge
clearances.
b. Check the depth-gauge clearance every time
the chain is led.
Use a at le and a depth-gauge jointer (both
available separately) to lower all gauges uniformly
(Fig. 13h). Use a 0.025 in. (0.6 mm) depth-gauge
jointer.
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.
