Grizzly G0512 Parallel Belt Tracking, To check the parallel tracking of the sanding belt

5.Turn the tension nut counter-clockwise until the threads of the tension shaft are flush with the nut, as shown in Figure 37.

Figure 37. Tension nut flush with threads.

6.Loosen the tracking control bolt (Figure 36, page 25).

7.Pull on the idler roller to take up the slack in the tension shaft.

8.Tighten the tracking control bolt.

9.Turn the tension nut clockwise approximate- ly three full turns.

10.Engage and disengage the belt tension lever, then tighten the tension nut two more full turns.

11.Adjust the idler roller-to-platen relationship as described on pages 29-30.

12.Install the sanding belt and table, and track the sanding belt before operating the sander. Note—It may be necessary to slight- ly adjust the tension nut to make the table fit.

Parallel Belt

Tracking

The belt should track on the rollers so that the top edge of the sanding belt stays parallel with the top edge of the platen graphite, as illustrated in Figure 38.

Figure 38. Illustration of parallel belt tracking.

To check the parallel tracking of the sanding belt:

Track the sanding belt, so that the side of the belt that is tracking higher is even with the top of the graphite.

—If the lower side of the belt is more than 1⁄8" away from the top of the graphite, write down the distance between the low side of the belt and the top of the platen, then proceed with the parallel belt tracking instructions.

—If the lower side of the belt is less than 1⁄8" away from the top of the graphite, then you do not need to adjust your belt for parallel tracking.
