ADJUSTMENTS

ADJUSTING THE PRESSURE ROLLER (Fig. 20 & 21)

There are two pressure rollers (Fig. 20 - 1) on each side of the sand-

ing drum. The rollers extrude slightly below the bottom of the drum

in order to press the workpiece against the conveyor belt as it passes

through the sander.

The pressure on the rollers is controlled by the springs and adjustment

screws that can be accessed from the inside of the drum housing. If the

roller pressure is too high, kickback and snipe may occur. If the roller

pressure is too low, the workpiece may slip on the conveyor belt. To

adjust the pressure of the rollers:

1. Turn off and disconnect the machine from the power source.

2. Remove the screw and washer securing the drum cover and lift the

cover open.

3. There are two screws (Fig. 21 - 1) on both ends of the drum. To

increase the roller pressure, evenly tighten all four Phillips screws by

ADJUSTING THE STOP SCREW (Fig. 22)

The heigh adjustment stop, controlled by the protrusion of the Phil-

lips head screw through the bottom of the frame, prevents the sand-

ing drum from contacting the conveyor belt. If necessary, re-adjust the

height adjustment stop screw as follow:

1. Turn off and disconnect the machine from the power source.

2. Loosen the height adjustment lock knob and raise the sanding drum

using the heigh adjustment wheel.

rotating them clockwise in small increments. To decrease the roller pressure, evenly loosen all four Phillips screws

in small increments.

4. To test the adjustments, turn on the machine and sand a scrap piece of workpiece. If the workpiece slips on the

conveyor belt, increase the pressure by rotating the four screws one turn clockwise. If the workpiece tends to kick

back, reduce the pressure by rotating the four screws one turn counterclockwise.

5. Repeat until roller pressure has been properly adjusted. Close the drum cover and replace the washer and cap

screw.

3. Loosen the hex nut on the stop screw and adjust the height of the screw (Fig. 22 - 1) to protrude above the frame

higher than 1/4 inch.

4. Tighten the hex nut and lower the sanding drum until the motor mount frame touches the top of the stop screw.

5. Check that the bottom of the sanding drum is at least 3/16" above the surface of the conveyor belt. If the distance

is too close, repeat the steps above to re-adjust as necessary.
