Adjusting Belt Tracking; Replacing Sanding Disc - Grizzly G0864 Owner's Manual

Adjusting
Belt Tracking
The purpose of belt tracking is to make sure
the belt stays centered on the pulleys during a
sanding operation. Although belt tracking is set at
the factory, it needs to be checked any time you
change or replace the sanding belt.
To check and adjust belt sander tracking:
1. DISCONNECT MACHINE FROM POWER!
2. Remove belt cover.
3. Standing in front of sander, push downward
on sanding belt multiple times along bottom
pulley and watch how belt tracks on top
pulley.
— If sanding belt moves right, rotate belt
tracking control knob clockwise
— If sanding belt moves left, rotate belt track-
ing control knob counterclockwise
(see Figure 12).
