Lathe is heavy – use caution
during leg installment procedures. Use straps in
good condition. Straps/lifting mechanisms must
be properly rated for lathe weight.
6.4.1
Hoist lifting method
1. Position straps around lathe bed.
IMPORTANT:
Do
not
place straps around spindle, near levers,
knobs or other parts that can be damaged when
lifting.
2. Position lathe onto legs and secure with screws
and washers (HP001/2/3, Figure 5) using 6mm
hex key.
3. Tighten screws firmly.

6.4.2
Manual lifting method
Use help from an assistant for
the following procedures.
1. Unscrew stud (see N, Figure 6) from each end
of bed. (Note: studs can be stored in one of the
threaded holes in lathe legs.)
2. Remove headstock, tailstock and tool rest
support from bed. (Refer to
sect. 8.0
for detailed
instructions on adjusting and removing these
items.)
3. Carefully turn bed upside down. Place a mat or
cardboard beneath it to prevent scratching the
bed ways.
4. Install legs with screws and washers
(HP001/2/3, Figure 5) using 6mm hex key.
Tighten screws firmly.
5. Raise bed and leg assembly right-side up.
6. Rotate adjustable feet (Figure 4) as needed to
establish level for the lathe. Tighten hex nut on
each foot against leg casting.
7. Install headstock, tool support and tailstock,
and both studs (N, Figure 3).

Mounting bed extension (optional
accessory)
8mm hex key required.
The 20” bed extension (p/n 719401) is optional and
purchased separately. See your JET dealer for
information. If you did not purchase the bed
extension, proceed to section 6.6.
The bed extension can be mounted to the upper or
lower holes of the lathe. Mounting in upper holes
increases the spindle length capacity of the lathe.
Mounting the extension to the lower holes allows
use of the tool support during outboard turning.
1. Slide tailstock away from edge of bed.
2. Have an assistant hold bed extension flush to
end of lathe bed, and insert four 3/8” socket
head cap screws with lock washers and flat
washers, provided with the bed extension (P,
Figure 6). Snug screws just enough to hold bed
extension to lathe bed.
3. Unscrew stud from lathe bed (N
1
), and insert it
into hole at end of bed extension (N
2
).
4. Adjust bed extension to lathe bed, aligning the
surface and the inside ways as closely as
possible.
2.
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 (Figure
14). 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 of the joint. Make further
adjustments if needed.
