IMPORTANT: Make sure the electrical characteristics are the same on the motor nameplate and the power source, and make sure the circuit on which the jointer will be used is properly fused and that the wire size is correct.

Converting from 230 Volt to 460 Volt (Three Phase Only)

Consult the wiring diagram inside the starter box cover. A diagram is also included on pages 37- 38 of this manual. The Jointer must comply with all local and national codes after being wired.

1.Remove the starter box cover and adjust the dial on the relay (see Figure 10) as close as possible to the amperage of the Jointer motor at 460V, as listed on the motor plate.

2.Move the fuse (Figure 10) from the 230V slot to the 460V slot.

3.Re-connect the incoming leads to the motor for 460 volt operation, as shown in the wiring diagram.

4.If using a plug, install a proper UL/CSA listed plug suitable for 460 volt operation.

Three-Phase Test Run

On the three-phaseunit, after wiring has been completed, you should check that the incoming leads have been connected properly:

1.Connect machine to power source and press the start button (make sure cutterhead is clear of all obstructions!).

2.The cutterhead should rotate clockwise as viewed from the front of the machine. If the cutterhead rotation is incorrect, press the stop button and disconnect machine from power.

3.Switch any two of the three leads to the motor.

Extension Cords

Make sure your extension cord is in good condition. Always use a cord that is heavy enough to carry the current your product will draw; the cord rating must be suitable for the amperage listed on the machine’s motor plate. An undersize cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 11 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
