Prevent overload of the Belt Sander Motor by pressing to much with your glass to the Grinding or Polishing Belts.
Our advise is to put the belts in water, for twenty-thirty minutes before using them .
This improves the performance and life time of your belts.
Do not tighten up the belts to much, this can cause a run off of the Belt to the left or right.
If your belt is running of to the left or right, release the belt tension with the Tension Knob or adjust the tilt position of the upper Belt Wheel.
