ADJUSTMENTS

Drums and Pressure

Rollers

Adjust the sanding drums and pressure rollers correctly. Complete PART 1, PART 2, PART 3, and PART 4 of this section in sequence. Otherwise, the sanding drums can grab and project the workpiece damaging the sander, and injuring you and bystanders!

To get the best sanding results and longest life out of your sandpaper, both the front and rear sanding drums must: (1) be square with the conveyor table, (2) run parallel with each other and parallel to the conveyor feed direction, and (3) must be slightly staggered in height with one another. Pressure-roller spring tension and height must also be set correctly.

As you become more familiar with your sander you can vary your sander settings to fine-tune the machine for your ultimate sanding goals.

Keep your drum sander unplugged during these adjustments. Otherwise, serious personal injury may occur!

PART 1: Drum-to-Conveyor Squareness

For this adjustment, you will align the drums so the drums are square with the feed conveyor belt surface. See Figure 18.

To adjust the drum-to-conveyor squareness, do these steps:

1.Make two gauge blocks from a quality piece of straight two-by-four hardwood stud. One block should be 30" long, and the other 25⁄8" long. See Figure 16.

2.Unplug the Double Drum Sander!

3.Unlatch and open the dust hood. See Figure 17.
