V-Belt Tension

The sanding drums are driven by two heavy-duty V-belts. After drum adjustments and normal operation, the belts may need adjustment. The belt looseness or deflection must be approximately 1".

Keep your drum sander unplugged during all assembly, maintenance, and adjustment tasks. Ignoring this warning can cause serious personal injury to you or others!

Make sure you inspect the V-belts correctly when adjusting the belts. Replace both belts even if only one is worn. Otherwise, one belt could slip and break, damaging the sander and injuring you and bystanders!

To inspect / adjust the V-belts, do these steps:

1.Unplug the Double Drum Sander.

2.Remove eight front panel mounting screws and remove the panel. See Figure 36.

3.At the halfway point between the drum pulley and the motor pulley, push on both belts with moderate finger pressure. The looseness or deflection must be approximately 1". See Figure 37.

4.Grab the belts one at a time, twist them, and use a flashlight to inspect the inside and outside of the belt. If you see deep cracks, fraying, chunks missing, or the belt is brittle and glazed; replace both belts.

5.Loosen the motor mounting nuts, and slide the motor on the mounting plate to adjust the belt. See Figure 38.

6.Tighten the motor mounting nuts, recheck and readjust the belts as necessary.

7.Reinstall the front panel.
