The amp load meter on the control panel (see Figure 23) shows how much amperage the sand- ing motor is drawing for the operation. When the depth of cut or conveyor feed rate becomes too great, the sanding motor will draw an excessive power load, which may trip the circuit breaker or damage the machine.
Figure 23. Amp load meter.
NOTICE
DO NOT VOID THE WARRANTY! Keep the amp load within the green SAFE range. If you operate the sander above 14 amps or in the red WARNING range, capacitor or motor failure may occur and will not be covered under warranty.
Always start with a shallow depth of cut to remove any high spots, then carefully increase the cut depth. Keep the amp load in the SAFE range dur- ing the entire operation (see Figure 24).

Sanding Tips
Follow these instructions to ensure safe sanding operation and quality results:
•Replace the sandpaper with a higher grit to achieve a finer finish (refer to Choosing Sandpaper on Page 20).
•When making multiple passes on the workpiece, avoid lowering the sanding belt more than 1⁄64" (0.016" or 2⁄3 of a turn of the handwheel) for any one pass.
•Feed boards into the sander at different points on the conveyor to maximize sandpaper life and prevent uneven conveyor belt wear.
•DO NOT sand boards less than 6" long, 2" wide, or 1⁄4" thick to avoid possible kickback, or damage to the workpiece or sander.
•Extend the life of the sandpaper by regularly using a
Starting the sanding motor with a workpiece in contact with the sanding belt could cause it to kickback into the operator resulting in serious personal injury. Never start the sander with a workpiece or any object on the conveyor belt.
