Checking Belt
Tracking
proper belt tracking depends on two conditions:
1) the platen height, and 2) the upper roller paral-
lelism.
the upper belt roller is designed with a slight
crown in the middle, and the belt platen should be
even with the highest point of this crown to ensure
proper belt tracking.
additionally, the upper roller should be parallel
to the lower roller so that the sanding belt rides
evenly in the middle of the rollers.
To check the belt tracking:
1. disConneCt sander From poWer!
2. put on heavy leather gloves to protect your
hands from the abrasive sandpaper
3. rotate the sandpaper belt down toward the
table several times by hand—not by pow-
er—as fast as possible (see
figure 23).
— if the belt stays centered on the rollers,
continue to the Dust Collection procedure
on page 22.
— if the belt begins moving to one side or
the other, perform the Tracking Roller &
platen Adjustment on page 35 to make
sure the belt tracks properly.
