Powermatic WB-37, WB-25, WB-43 Operating Controls, Amperage Meter, LED Controller and Keypad

If the readings are different, the table needs adjusting.

2.Disconnect sander from power source.

3.At the area of the table that needs adjustment, loosen the two screws (A, Figure 18) on the bracket of the elevation screw, and rotate the bracket as needed. (The elevation screw is protected by the dust guard bellow.) Turn the elevating screw clockwise to lower the table in that area, counterclockwise to raise the table (see Figure 18).

IMPORTANT: Turn both elevating screws at one side of the table an equal amount, in order to maintain front-to-back parallelism with the rollers.

4.Tighten screws (A, Figure 18).

5.Re-connect sander to power, and make further test runs. Make additional adjustments as needed, with the machine disconnected from power.

10.0Operating Controls

Figure 19 shows the control panel functions.

The emergency stop button shuts down all machine operations. The button remains engaged after being pushed. To disengage, rotate the ring until the emergency stop button pops back out.

The emergency stop cover has a plate (shown in Figure 16) which shuts down all machine operations when it is pushed.

10.1Amperage Meter

The amperage meter (Figure 19) continually monitors the load upon the sander. To avoid tripping of the circuit breaker and the overload relays, reduce the load immediately when the amperage meter indicates excessive amperage pull.

10.2LED Controller and Keypad

The controller is used for precise positioning of the conveyor table based upon the workpiece thickness and your desired sanding depth.

Figure 20 shows the key features of the unit.

The LED control unit comes pre-programmed from the factory. Do NOT alter the specifications of your control unit without authorization from WMH Tool Group. Incorrect programming of the device could cause unit failure as well as risk of injury to people and damage to the sander.
