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.
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-phase unit, after wiring has been
completed, you should check that the incoming
leads have been connected properly:

press the start button (make sure cutterhead
is clear of all obstructions!).
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.

An undersize cord will cause a drop in line
voltage resulting in loss of power and

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.
