Figure 6-1: grounding
IMPORTANT: The JWL-1640EVS Lathe cannot be
run on a GFCI circuit.
A lightning strike or power
surge may cause inverter failure. When lathe is
not in use, disconnect power plug, or have a 3-
or 4-pole disconnect installed on the power
side.

6.3 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 it is 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 recommended 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.

7.2 Tailstock movement

To slide tailstock, push locking handle (C, Figure 7-
3) down toward bed. Push handle up to lock
tailstock in position.
To move quill, loosen handle (D) and rotate
handwheel (E).
Make sure tailstock is locked
to bed (C) and quill is tightened (D) before
turning a spindle on the lathe.

7.3 Removing items from bed

To remove headstock, tailstock or toolrest base
from bed, unscrew and remove either of the studs
(see O, Figure 5-6). Unlock the item and slide it off
bed. After remounting these items on the lathe,
reinstall studs.
For most turning operations, except outboard
turning, the headstock is positioned at the left end
of bed, and the tailstock moved to accommodate
the workpiece.

7.4 Cam tightness

The clamping mechanisms of headstock, tailstock
and tool rest base are pre-set by the manufacturer,
and should not require adjustment.
If one of them does not tighten properly against the
bed when the locking handle is tightened, adjust it
as follows. (Figure 7-4 uses tailstock as example.)
