If the conveyor table is still difficult to raise or lower, the table supports may need to be re- centered on the columns. To do this, loosen the four 3/8”x1” hex head bolts in each table support that connects it to the table mounting brackets, adjust and tighten the set screws (see Figure 5) to hold the table support in position. Then tighten the hex head bolts and re-loosen the set screws. Re-align drum (see page 17).

Replacing V-Belt

1.Unplug machine from power source.

2.Remove the outer half of belt guard by removing the six #10-32 screws with a 5/16” wrench. Slide the belt guard away from the v-belt. See Figure 37.

3.Use a flat blade screwdriver to pry off the protective cap over the inboard miter gear, and loosen the set screw in the gear’s collar. Remove the miter gear and loosen outboard collar (Figure 38). Slide cross bar toward outboard side as shown.

4.Loosen v-belt tension by loosening pinch bolt in motor support (Figure 38) and raise motor. Remove v-belt from pulleys.

5.Install new v-belt and tension the belt by using the weight of the motor only. Make sure the pulleys are aligned. Replace transfer rod and miter gear; tighten set screw on miter gear and replace protective cap. Tighten collar on transfer rod.

6.Install the outer half of the belt guard and tighten the six screws.

Rotating Drum Bearings

Bearings should be replaced when they allow excessive play of the drum, make excessive noise or otherwise indicate failure.

If clicking noises in the bearings are a problem, rotating may be a solution instead of replacement, as follows:

1.Unplug sander from power source.

2.Loosen the set screws in the bearing collar (Figure 39). Leave the set screw wrench in one of the set screws. Then rotate the drum within the bearing and tighten the set screws.

3.If the clicking persists, or if the drum shaft is tight in the bearing and cannot rotate, then loosen the bearing bolts. Repeat step 2. After the drum is rotated within the bearing, tighten the bearing bolts first and then the set screws.
