If the jointer is to be hard-wired to a panel, make
sure a disconnect is available for the operator.
During hard-wiring of the machine, make sure
the fuses have been removed or the breakers
have been tripped in the circuit to which the
jointer will be connected. Place a warning
placard on the fuse holder or circuit breaker to
prevent it being turned on while the machine is
being wired.
Grounding Instructions
This machine must be grounded. In the event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
Improper connection of the equipment-
grounding conductor can result in a risk of
electric shock. The conductor with insulation
having an outer surface that is green with or
without yellow stripes, is the equipment-
grounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded. Repair or
replace a damaged or worn cord immediately.
IMPORTANT: Make sure the electrical
characteristics listed on the motor nameplate
match those of 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)
Refer to Figure 14.
Consult the wiring diagram inside the starter box
cover. A similar diagram is also included at the
back 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 overload relay as close as
possible to the amperage of the motor at
460V, as listed on the jointer’s motor plate.
2. Move the fuse from the 230V slot to the
460V slot.
3. Re-connect the incoming leads to the motor
in accordance with 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.
