4.Lower the conveyor table and position the 30" gauge block under one end of the front drum and flush with the end of the conveyor. See Figure 19.

5.Turn the micro adjusting knob and raise the rear drum so it will not contact the gauge block.

6.Rotate the front drum by hand, and raise the conveyor table until you hear the gauge block barely rub the underside of the front drum.

7.Move the gauge block to the other side of the conveyor table under the other end of the front drum.

8.Rotate the drum again and listen and feel the drag to determine which end of the drum is too low or high.

9.At the low end of the drum, loosen the bearing-block mounting nuts 14 to 13 turn. See Figure 20.

NOTICE

DO NOT over-tighten the bearing block mounting nuts. The bearing blocks are machined housings that can warp or crack if the nuts are over-tightened.

10.Use a 4 mm Allen® wrench to equally turn the set screws at one end of each adjustment plate

18" turn at a time to raise the bearing block height at the low end of the drum. Remember, adjusting one drum-end slightly affects the adjustment at the opposite end. See Figure 20.

11.Repeat Steps 1 through 10 to achieve front drum-to-conveyor squareness.

12.Tighten the nuts in an alternating pattern and recheck the squareness.

13.Now use the 30" gauge block at the rear drum to find which end is too low.

14.Unlock the micro-adjustment lock knob, and turn the micro-adjust knob to adjust the rear drum height. See Figure 21.Unlike the front drum, there are no set screws to adjust the rear drum height.
