3.The Reset button (Figure 5) will light up if the machine becomes overloaded. Press this button to re-start the machine.

4.The Emergency Stop Button shuts down all operations on the planer. An automatic brake stops the motor within 10 seconds. A similar stop button can be found at the back of the machine. To restart the machine, simply twist the stop button and allow it to pop back up

5.To begin the feed motor and rotation of the feed rollers, press the Potentiometer button on the dial. Rotate the dial to set the feed speed. Speed ranges from 16 to 72 feet per minute. The numbers on the dial are shown as 1 to 11; the higher the number, the faster the speed. To stop the feed motor press the Potentiometer button again.

6.The Brake Release switch frees the cutterhead so that it can be moved by hand (e.g. when changing knives). When the brake release is on, the switch stays lit. As a safety feature, the planer’s motor will not start if the brake release switch is lit. And if the switch is pushed during operations, the motor will automatically stop. To restart the planer, de-press the brake release switch; the light will turn off.

7.To raise the table press the up-arrow buttons; to lower the table press the down- arrow buttons. The single arrows raise the table slowly, the double arrows rapidly.

Calibrating Digital Display

Before operating the planer, the digital display should be checked for accuracy and calibrated if necessary. Use a scrap board.

1.Set the table to just under the thickness of your scrap board, using the scale next to the table (Figure 6). Feed the board through the planer to achieve a planed side.

2.Raise the table slightly until the adjoining scale pointer is set evenly on a number.

3.Flip the board over and feed it through the planer, then carefully measure its thickness with calipers. Compare this with the digital display.

4.If the display needs correcting, press and hold “Function,” and press “Reset”. The display will return to zero.

Figure 6

5.Press and hold “Function,” and press “Set” until the display shows the thickness of your board. Tapping the “Set” button will move the display by increments; holding down the “Set” button will move the display rapidly.
