POLE SAW ATTACHMENT — PSA100030
Side Plate Sharpening Angle
(Fig. 23)
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
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 led.
Use a at le 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
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.
