Sanding Belt Installation

SET UP

1.Before installing the belt, clean the protective grease from the upper metal sanding belt roller as per the Cleaning Machine instructions on Page 11.

2.DISCONNECT THE SANDER FROM POWER, but keep the air pressure applied into the machine.

3.Turn the sanding head lock lever counterclockwise and remove the lever and the steel spacer block.

4.Locate the arrows on the inside of the sanding belt. These arrows show the direction that the sanding belt is designed to rotate during operation. Facing the inside of the left-hand access door, the sanding belt will rotate counterclockwise.

5.Install the sanding belt as shown in Figure 8, and center it on the rollers and in between the ceramic limit switch levers.

6.Reinstall the steel spacer block, the sanding head lock lever, and turn the lever clockwise to lock the headstock.

Sanding Belt Tensioning

When air is applied to the system (75 PSI), the switch shown in Figure 9 automatically sets the belt to the cor- rect tension. When the air pressure is connected and the switch is flipped up, the belt will automatically tighten to the correct tension. Flipping the switch down will immediately exhaust the air and release the belt ten- sion.

You must tension the sanding belt before starting the sander, and de-tension the belt when sander is not in use, or you will stretch the belt.
