Adjusting the Belt Tracking
The sanding belt must be centered on
the contact wheel to avoid damaging the
sander and to allow for optimal sanding.
To adjust the belt tracking:
1. Connect the sander to compressed air
regulated at 70-90 PSI.
2. Hold the sander firmly and press the
throttle lever to turn it ON. Once the
belt has reached full speed, turn the
adjustment knob to adjust the belt
tracking. Turning the knob clockwise
will move the belt towards the adjusting
knob and turning the knob counter-
clockwise will move the belt away from
the adjusting knob (
Figures 12 & 13).
