Initial Drum Alignment

3.Insert the gauge between the drum and conveyor bed at one end of the drum (Figure 26). Raise the conveyor bed while slowly rotating drum by hand until the drum lightly contacts the thickness gauge.

4.Move thickness gauge to the opposite end of the drum. If the drum does not contact the thickness gauge equally at both ends of the drum, alignment is necessary. See below.

1.Release v-belt tension from motor by loosening pinch bolt of motor support (Figure 27).

2.Loosen two lower #10-32 screws in belt guard (Figure 27 shows one of the screws). Slide motor support up the column and re- tighten pinch bolt.

3.Because the tension roller suspension assembly (Figure 28) mounts to the drum bearing bolts which are used to adjust the drum, it is necessary to align the sanding drum and tension rollers at the same time. Loosen outboard bearing bolt knobs (Figure 28) and the inboard bearing bolts.

4.With all four bearing bolts loosened, note that the drum will adjust about 1/2” on each end. Position drum alignment templates (Figure 28) on the conveyor and below the drum with one template at each end of the drum.

5.Raise the conveyor bed so that the drum is resting on both templates but leaving the drum within its range of adjustment. To check this, you should be able to lift either end of the drum off the templates and, with light hand pressure on the drum, attempt to slide templates with a screw driver to make sure drum is actually resting on the template and not just in its lowest position.

6.In this position, the drum should be resting on the templates and both tension rollers resting on the conveyor surface. Re-tighten bearing bolts and restore v-belt tension. Tighten pinch bolt in motor support and tighten two lower screws in belt guard (Figure 27).

Fine-Tuning Drum Alignment

The 22-44 Pro is equipped with a drum adjuster mechanism that allows easy fine tuning or changing of drum alignment without repeating the intial drum alignment procedure.

1.Raise drum adjustment lever (Figure 29) so that it just engages the side of drum carriage leg.
