2. Have an assistant hold bed extension flush to
end of lathe bed, and insert screws and
washers provided with bed extension (P,
Figure 5-6). Snug screws just enough to hold
bed extension to lathe bed.
3. Unscrew stud from lathe bed (O
into hole at end of bed extension (O
4. Adjust bed extension to lathe bed, aligning the
surface and the inside ways as closely as
possible.
IMPORTANT: Top surface of bed extension
must be flush with surface of lathe bed, and
inside ways must be aligned, to allow smooth
movement of tailstock across joint.
5. Slide tailstock over joint where beds meet, so
that clamping nut is centered over joint, as
shown in Figure 5-6. Lock tailstock clamping
handle; this will align the beds.
6. Securely tighten screws (P) in bed extension.
7. Unlock tailstock and slide it back and forth to
test smoothness
adjustments if needed.

6.0 Electrical connections

Electrical connections must
be made by a qualified
compliance with all relevant codes. This
machine must be properly grounded to help
prevent electrical shock and possible fatal
injury.
The JWL-1640EVS lathe requires 115-volt single-
phase input. It is equipped with a power inverter,
located between the power cord and the drive
motor. The inverter takes the 115V 1-phase input
from the power cord and converts it to the 230V 3-
phase output required by the drive motor.
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 6-1.
Before connecting to power source, be sure switch
is in off position.

6.1 GROUNDING INSTRUCTIONS

This tool 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. This tool is
equipped with
equipment-grounding conductor and a grounding
plug. The plug must be inserted into an appropriate
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
equipment-grounding conductor can result in a
risk of electric shock. Check with a qualified
electrician or service person if you are in doubt
as to whether the outlet is properly grounded.
Do not modify the plug provided with the tool –
if it will not fit the outlet, have a proper outlet
installed by a qualified electrician.
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
grounding conductor to a live terminal.
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
immediately.

6.2 115V operation

As received from the factory, your JWL-1640EVS
is ready to run at 115-volt operation. This tool is
intended for use on a circuit that has an outlet that
looks like the one illustrated in A, Figure 6-1. An
adapter, shown in B, may be used to connect this
plug to a 2-pole receptacle as shown in B if a
in
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. 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. Note: In Canada, the
use of a temporary adaptor is not permitted by the
Canadian Electrical Code, C22.1.
