3.Remove the four bolts attaching conveyor assembly to base. Lift up and slide conveyor out to the side of the machine.
4.Set conveyor on motor side and slide conveyor belt off the end of the conveyor bed.
5.Reverse process for installation of new belt.
Sanding Drum Alignment
The sanding drum must be aligned parallel to the conveyor bed for proper machine operation. The sanding drum comes preset from the factory. If a problem with the drum alignment occurs, follow the instructions below.
First inspect the alignment with a gauge of some kind. The following procedure uses a steel straight edge as a gauge.
1.Unplug sander from power source.
2.Open the dust cover and remove the abrasive strip from the drum.
3.Insert the gauge between the drum and conveyor bed at the outer end of the drum (Figure 23). With the dust cover open, lower sanding drum while slowly rotating drum by hand until the drum lightly contacts the thickness gauge.
4.Remove thickness gauge and place under drum at the other end (Figure 24). If the drum does not contact the thickness gauge to the same degree as the opposite end of the drum, alignment is necessary.
To align the drum:
1.Loosen the four 3/8” hex cap screws – two front, two rear (A, Figure 25). This allows the entire drum carriage and shroud to be pivoted on two screws – one screw in front, one in back.
2.Lay the thickness gauge under the drum lengthwise (Figure 26). Rotate the fine tune adjustment knob (B, Figure 25) until the drum contacts the gauge equally along its entire surface. Rotate the knob clockwise to raise the outboard end of the drum, counterclockwise to lower the outboard end of the drum. Use the height adjustment handle to raise or lower the entire drum.
3.When drum is parallel to conveyor, tighten the four screws (A, Figure 25).
