PART 4: Pressure Roller Adjustment

Depending on your sanding needs, adjust the pressure roller height and spring tension. See Figure 30.

To adjust pressure-roller height, do these steps:

1.Loosen all six height jam nuts. See Figure 31.

2.Position the 30" gauge block to one side of the conveyor belt and under the three pressure rollers. See Figure 32.

3.Turn the handwheel so the gauge block barely touches the rear drum and the handwheel tape is at the 12:00 position.

4.Now turn the handwheel counter-clockwise exactly 21⁄2 turns.

5.Turn the pressure-roller height bolt until the pressure roller just contacts the gauge block. See Figure 31.

6.Hold the height bolt in position and tighten the height jam nut.

7.Repeat Steps 1 through 6 at all rollers, and remove the gauge block.

To adjust pressure-roller spring tension, do these steps:

1.Loosen all six tension jam nuts, and back out the tension bolt completely. See Figure 31.

Too much pressure roller tension may cause the workpiece to jam.

2.Turn the tension bolt clockwise until it just makes contact with the spring and has resistance.

3.Turn the bolt one additional turn to adjust the spring to a basic spring tension value.

4.Hold the tension bolt in position and tighten the tension jam nut.

5.Repeat Steps 2 through 4 at all rollers.

6.Close and latch the dust hood, and check the V-belt tension.
