Belt Tracking
The purpose of belt tracking is to make sure the
belt stays centered on the wheels and platen dur-
ing grinding operations. Although belt tracking is
set at the factory, it needs to be checked any time
you change or replace the belt.
To check and adjust belt tracking:
1. DISCONNECT MACHINE FROM POWER!
2. Open belt access panel.
3. Standing at rear of sander, rotate drive wheel
with one hand and watch how belt tracks (see
Figure 19).
—If sanding belt moves toward motor (front
of grinder) rotate tracking knob clockwise
1
⁄
4
turn.
—If sanding belt moves away from motor
(toward back of machine), rotate tracking
knob counterclockwise
1
⁄
4
turn (see
Figure
19).
4. When belt is tracking in center of platen and
wheels, close belt access panel.
5. Connect machine to power source and turn it
ON, verify belt is tracking correctly in center
of platen and wheels, and fine-tune tracking
as necessary while sander is running.
