7.0 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.
The JWL-1440VS Lathe is rated at 115/230V
power, and is pre-wired for 115 volt. The lathe
comes with a plug designed for use on a circuit
with a grounded outlet that looks similar to the one
pictured in A, Figure 8.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the lathe, when operated
on 115 volt power, be connected to a dedicated
20 amp circuit with a 20 amp circuit breaker or
time-delay fuse marked “D”. When operated on
230 volt power, it is recommended that the lathe
be connected to a dedicated 15 amp circuit with a
15 amp circuit breaker or time-delay fuse marked
“D”. Local codes take precedence over
recommendations.
7.1 Grounding instructions
1. All Grounded, Cord-connected Tools:
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.
This tool is equipped with an electric cord having
an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided - if it will not fit the
outlet, have the proper outlet installed by a
qualified electrician.
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. Failure to comply
may cause serious or fatal injury.
Use only 3-wire extension cords that have 3-prong
grounding plugs and 3-pole receptacles that accept
the tool's plug.
Repair or replace damaged or worn cord
immediately.
2. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating less
than 150 volts:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in A, Figure
8. An adapter, shown in B and C, may be used to
connect this plug to a 2-pole receptacle as shown
in B if a properly grounded outlet is not available.
The temporary adapter should be used only until a
properly grounded outlet can be installed by a
qualified electrician. This adapter is not permitted
in Canada. The green-colored rigid ear, lug, and
the like, extending from the adapter must be
connected to a permanent ground such as a
properly grounded outlet box.
3. Grounded, cord-connected tools intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
This tool is intended for use on a circuit that has an
outlet that looks like the one illustrated in D, Figure
8. The tool has a grounding plug that looks like the
plug illustrated in D. Make sure the tool is
connected to an outlet having the same
configuration as the plug. No adapter is available
or should be used with this tool. If the tool must be
reconnected for use on a different type of electric
circuit, the reconnection should be made by
qualified service personnel; and after reconnection,
the tool should comply with all local codes and
ordinances.

7.2 Voltage conversion
To switch the incoming power leads for 230 volt
operation:
1. Remove the junction box cover on the motor
and reconnect the leads according to the
diagram inside the cover. A similar diagram is
found at the back of this manual. (Note: In the
event of discrepancies, the diagram inside
junction box takes precedence.)
2. Remove the 120V plug on the end of the motor
cord and replace it with a UL/CSA listed plug
rated for 240V.
