ADJUSTMENTS

PART 3: Drum-to-Conveyor Height

For this adjustment, you will find a reference height for the front drum and then adjust the rear drum so it is 0.007" to 0.010" lower than the front drum. See Figure 27.

NOTICE

Make sure you use the same part of the 30" gauge block at the opposite side of the conveyer belt when adjusting the drum-to-conveyor height. Otherwise, the adjustment may be inconsistent.

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

1.Lower the conveyor table, and position the 30" gauge block to one side of the conveyor belt and flush with the end of the feed conveyor drive roller. See Figure 28.

2.Raise the conveyor table so the gauge block barely touches the front drum and mark this height position with tape on the handwheel at the 12:00 o’clock position. See Figure 29.

3.Turn the handwheel counter-clockwise exactly

12 turn to lower the conveyor.

4.Unlock the rear-drum micro-adjusting lock lever and turn the micro-adjusting knob so the rear drum lowers until it just barely touches the gauge block.

5.Repeat Step 14 at both ends of the rear drum.

NOTICE

Once the rear drum height is set, the height can be fine-tuned later without having to complete all four parts of this section. However, you must make sure that when you adjust the rear drum height you adjust it equally on both sides so it stays square and level with the conveyor table. Using a pencil, mark a squiggly line on the workpiece and sand it to test for even sanding. Look for uniform removal of the line. If the line is not removed uniformly, readjust the sander accordingly.
