Slack Grinding
Slack grinding is positioned similarly to flat grind-
ing, but with the platen removed. This is most use-
ful for contour sanding where the belt conforms to
the shape of the workpiece.
To perform slack grinding:
1.
DISCONNECT MACHINE FROM POWER.
2.
Remove (2) cap screws and flat washers
shown in Figure 33 to remove platen.

4.
Connect machine to power, turn it ON, and
allow it to reach full speed.
5.
Position workpiece against work table/rest if
feasible, then slowly feed it into moving belt
with light, even pressure (see Figure 36).
Move workpiece to different locations to wear
sandpaper evenly and to prevent it from over-
heating.
