4. When all holes have been bored, place the
2x6’s on edge in the outer ledges of the Lathe.
5. Cut the dowel rods to length with a miter saw
or hand saw, so that after insertion the rods
will be flush with the back of the rear 2x6.
6. Insert the dowel rods through the holes in the
rear 2x6, as shown in Figure 12.
7. A strip of wood can be screwed to the rear 2x6
to cover the dowel holes and prevent the
dowels from working out.

8.0 Electrical connections
Electrical connections must be
made by a qualified electrician in compliance
with all relevant codes. This machine must be
properly grounded to help prevent electrical
shock and possible fatal injury.
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.
The Lathe will operate on single phase or three
phase, 230 volt power supply. Make sure the
characteristics of your power supply match the
specifications on the motor plate of the Lathe. It is
recommended that the lathe be connected to a 20
Amp circuit with circuit breaker or time delay fuse.
Local codes take precedence over recommend-
dations.
8.1 Single Phase Operation
A three wire pigtail for use on 230 volt single phase
power is attached to the inverter and may be “hard-
wired” to the power source, or connected to a
UL/CSA listed receptacle plug.
Connect the 230 volt supply to the black and white
leads and ground the green lead.
If you are hard-wiring the Lathe to a panel, make
sure a disconnect is available for the operator.
During hard-wiring of the Lathe, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the Lathe 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.
8.2 Three Phase Operation
If three phase power is used, it will be necessary to
replace the pigtail wire attached to the inverter with
a 12/4 wire and connect the three hot leads to the
inverter at R, S, T as shown in the wiring diagram
in sect. 17.0. Always connect the ground lead.
8.3 Extension cords
The use of extension cords is discouraged. Try to
position machines within reach of the power
source. If an extension cord becomes necessary,
make sure the cord rating is suitable for the
amperage listed on the machine’s motor plate. An
undersized cord will cause a drop in line voltage
resulting in loss of power and overheating.
Use the chart in Table 1 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.
