W1772/W1773 37" Drum Sander

Drum Adjustments

There are three adjustments for the sanding drums: 1) the drums must be perpendicular to the feed direction (par- allel with the conveyor roller, Figure 49); 2) the drums must be parallel to the top of the conveyor belt (Figure 54, Page 40); 3) the rear drum must be set approximate- ly 0.007" to 0.015" below the front drum (Figure 58, Page 41).

At some point, you may need to readjust the rear drum parallel to the conveyor if you change the rear drum height to accomodate for different sandpaper thicknesses or finish requirements. Make sure the rear drum does not sit lower than 0.015" below the front drum.

Adjusting Drums Perpendicular to Feed Direction

The tolerances for having the drum perpendicular to the feed direction allow up to 1⁄8" difference from one side to the other (see Figure 49). If the drums are not per- pendicular to the feed direction (in other words, parallel to the conveyor rollers), they may put a side load on the conveyor belt during operation, forcing the conveyor to track off to the side and possibly causing damage.

To adjust the drums perpendicular to the feed direc- tion, do these steps:

1.DISCONNECT POWER TO THE SANDER!

2.Check to make sure the conveyor roller is parallel to the machine frame, and make adjustments if need- ed. (Refer to Page 36.)

3.Open the top and pulley covers and remove the V- belts (refer to Page 33 for V-belt removal instruc- tions).

4.Remove the sandpaper from the drums for best results.

5.At both ends of the rear drum, measure the distance between the edge of the rear drum and the rear upper frame, as shown in Figure 50. The difference between these two measurements will tell you how close the drum is to being perpendicular to the feed direction (assuming that the conveyor roller is paral- lel to the machine frame).

—If the difference between the two measurements at each end are within 1⁄8", skip to Step 8.
