approved grinding wheel dresser and dress the
wheel face.
7.2.2 Belt and Disc grinding
1. Remove belt before grinding on disc, to prevent
accidental contact of hands with belt.

Grinding on upward side may cause workpiece
to catch and slip from your grasp.
3. At all times, keep hands and fingers away from
pinch points while grinding in disc or belt area.

) with 14mm
wrench.
2. Slide spark guard (B

8.4 Belt tracking
Rotate belt by hand to check tracking. If belt shifts
to one side or the other, move tracking lever (D,
Figure 8-2) while rotating belt until belt completely
covers contact wheel and stays centered. Move
lever (D) down for left adjustment, up for right
adjustment. Turn on grinder to verify setting at
operational speed.
If belt refuses to track properly, the rubber contact
wheel must be adjusted parallel to the drive wheel,
as follows (13mm or 1/2" wrench required):
1. If belt wanders away from grinder, loosen top
bolt (E, Figure 8-2) and tap top of cam plate (F)
away from grinder.
2. If belt wanders toward grinder, loosen top bolt
(E) and tap top of cam plate (F) toward grinder.
3. Retighten bolt, and use lever (D) for final
tracking.

8.5 Platen adjustment
The platen should be set so that it just contacts
underside of tensioned belt, but not so high that belt
rides up over it, which will hasten wear to belt and
machine. Loosen hex nuts (G, Figure 8-3) and
adjust as needed.
