W1772/W1773 37" Drum Sander

Using the Amp Draw

Meter

The amp draw meter (Figure 26) is used to keep the machine from being overloaded during sanding operations.

As a general rule, always start with a shallow sand- ing depth and carefully increase the sanding depth. Keep the amp load in the green range during operation. Generally, the normal depth of cut is no more than 1⁄64" or 0.016" for a 361/2" wide board using coarse sandpaper. DO NOT work your machine in the red zone as shown on the Amperage Load Chart. If operated in the red zone, the motor will lose RPM, the start capacitor will ener- gize, and capacitor or motor damage will occur.

Amp load is directly affected by many factors such as feed rate, depth of cut, wood type, sandpaper grit, and workpiece width.

W1772	Maximum Amp Load	44A
W1773	Maximum Amp Load at 220V	40A
W1773	Maximum Amp Load at 440V	20A

Sanding

To sand a workpiece, do these steps:

1.Adjust the table height according to the instructions in Depth of Cut on Page 24.

2.Start the dust collector, the drum motor, and the feed motor.

3.Feed the workpiece through the sander while stand- ing to the side and monitor the amp meter; if it approaches the maximum amp load, lower the con- veyor table.

4.Run wide stock through two or three times with- out adjusting the table height. Turn the stock 180° between passes to ensure an even cut. Do not sand more than one workpiece at a time side-by-side.

Close all covers and panels before starting the drum sander. Failure to do so could result in severe personal injury.

DO NOT sand more than one board at a time side-by-side. Minor variations in thickness can cause one board to be propelled by the rapidly spinning sanding drum and ejected from the machine. NEVER stand directly in front of the machine. Failure to do so could result in severe personal injury.
