Electrical Connections; Grounding Instructions; Extension Cords - Jet JWL-1221VS Operating Instructions And Parts Manual

8.0 Electrical connections

The JWL-1221VS JET lathe is rated for 115 volt
operation. It is supplied with a plug designed for
use on a circuit with a grounded outlet that looks
like the one pictured in A, Figure 9.
Before connecting to power source, be sure switch
is in off position.
It is recommended that the lathe be connected to a
dedicated 10 amp circuit with a circuit breaker or
time-delay fuse. Local codes take precedence
over recommendations.

8.1 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
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.
replacement of the electric cord or plug is
necessary, do not connect
grounding conductor to a live terminal.
Check
electrician or service
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
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
9. 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
conductor and 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.

8.2 Extension cords

The use of extension cords is discouraged. Try to
position equipment within reach of the power
source. If an extension cord becomes necessary,
be sure to use one heavy enough to carry the
current your product will draw. An undersized cord
will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows correct size
to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier
the cord.
