OPERATIONS

Emergency Stop

When pushed, the emergency stop plate shown in Figure 26 stops electricity to the motors and stops the sander quickly by using a disc brake on the drive motor.

KEEP the sanding drum drive belts correctly adjusted. If the belts are loose, and the emergency stop is engaged, the sanding drum pulley will slip and not immediately stop in the event of an emergency!

To apply the emergency stop, do these steps:

1.Push the bottom of the emergency stop plate as far as it will go.

2.Hold the emergency stop plate until the sander has come to a complete stop.

Keypad and Display

The conveyor table lift motor is controlled by the key pad and indicated on the digital display shown in Figure 27. You can push the UP or DOWN arrow keys to lift or lower the table, or you can use the automated function of auto height adjustment for your next sanding pass. All functions are controlled through the key pad and are presented on the digital display. See Figure 27.

Calibrating the Table

When you change the sandpaper or you notice and inconsistency with the actual sanding thickness in relationship to your digital setting, you must re-calibrate the table.

To re-calibrate your table, do these steps:

1.Insert a calibration board that is 1-12" thick.

2.Press the UP arrow key:

so the table lifts and the sandpaper just touches the surface of the calibration board. For fine tuning the clearance, use the handwheel shown in Figure 28 instead of the arrow keys. DO NOT hold or grab the handwheel when using the arrow key, as the motor is driving the handwheel in that mode of operation.
