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).
