5. Transport and start up
5.1 Transport and installation
The machine is designed to operate in closed rooms and
must be placed stable on firm and levelled ground.
The machine can be bolted down if required.
For packing reasons the machine is not completely
assembled
5.2 Assembly
If you notice transport damage while unpacking, notify your
supplier immediately. Do not operate the machine!
Dispose of the packing in an environmentally friendly manner.
Clean all rust protected surfaces with a mild solvent.
Attach the leg stand:
At this point the headstock, tailstock and tool rest should be
removed.
Unscrew the stud (N, Fig 4) from each end of bed.

Fig 4
Remove headstock, tailstock and tool rest support from bed.
The machine bed is heavy! With the help of a second person.
Carefully turn bed upside down. Place a mat or cardboard
beneath it to prevent scratching the bed ways.
Install legs with eight screws, lock washers and flat washers.
Tighten screws firmly with 6mm hex key. (see Fig 5).
Fig 5
Fig 6
With the help of a second person, raise bed and leg
assembly right-side up.
Rotate the levellers as needed to establish level for the lathe.
Tighten the hex nut on each leveller against the leg casting.
If you desire to install the riser blocks for a 100mm height
increase, mount them to bottom of legs using fasteners
(HP006/5/7) Tighten firmly.
Install adjustable feet into bottom of legs or riser blocks
(Figure 6) and tighten hex nut against leg casting. The feet
can be adjusted later.
Now headstock, tool rest and tailstock can be installed again
(Fig 7). Install both studs (N, Fig 4).
Fig 7
Installing bed extension: (JET Option # 719401)
The bed extension can be mounted to the upper or lower
holes of the lathe.
Mounting the extension to the lower holes allows use of the
tool support during outboard turning (Fig 8).
Fig 8
Mounting in upper holes increases the spindle length capacity
of the lathe.
Have an assistant hold bed extension flush to end of lathe
bed, and insert four screws with washers (P, Fig 9).
Snug screws just enough to hold bed extension to lathe bed.
Unscrew stop bolt (N) from lathe bed and insert it into hole at
end of bed extension.

Fig 9
Top surfaces and inside ways must be flush to allow smooth
movement of tailstock.
Slide tailstock over joint where beds meet, so that clamping
nut is centred over joint. Lock tailstock clamping handle; this
will align the beds.
Securely tighten screws (P) in bed extension.
Guard (optional accessory)
The guard (part no. 719002) is optional and purchased
separately. See our website for information.
Loosen set screw on outer collar (shown in Figure 10) with
4mm hex key. Slide outer collar off the guard support rod.
Insert guard support rod into mounting bracket at rear of
headstock. You will have to lift up on spring pin, as shown, to
slide guard support rod into mounting bracket. Release spring
pin and it will snap into position as you slide support rod
farther in.
Install outer collar and tighten set screw.
The guard can be pivoted to one of two positions: Operating
mode (shown on front cover) or tilted back for stock loading
(Figure 10-1).
Pull up on spring pin, and begin tilting guard, then release
spring pin. When guard reaches either of the two positions,
spring pin will engage.
Figure 10-1
Figure 10-1
Spindle comparator (optional accessory)
The spindle comparator bracket and centers are optional
and purchased separately.
The spindle comparator consists of two centers inserted
into the brackets at rear of lathe. The comparator is used
to mount a finished, or “reference” spindle, from which
measurements can be taken, the measurements being
transferred to the new piece being turned.
Install comparator spur center into guard bracket, by lifting
up on plunger and inserting comparator spur center until
its point is about even with the point of the spur center in
the headstock spindle. See Figure 10-2. The plunger in the
bracket should engage one of the holes in the comparator
center at this position.
Install comparator bracket to tailstock with provided
fasteners (Figure 10-2). Hand tighten only.
Install comparator dead center in the comparator bracket
and tighten lock handle.
Slide tailstock toward headstock until comparator centers
almost touch. Adjust comparator bracket as needed until
centers align. Tighten screws firmly.
Mount spur center with the spindle blank that you will be
turning. Loosen tailstock locking handle, and slide tailstock
until live center is about 25mm from spindle blank, then
tighten locking handle. Advance live center using tailstock
handwheel, until live center is secured in spindle blank.
Mount reference spindle between comparator centers.

palm of your hand keeping your fingers closed.
(see Fig 11 and 12)
Fig 11
Fig 12
6.2 Tool selection:
Successful wood turning does not result from high speeds,
but rather, from the correct use of turning tools.
A perfect and sharp wood turner tool is a precondition for
professional wood-turning.
Major tools:
Fig 13
Gouge (A, Fig 13), used for rapidly cut raw wood into round
stock, for turning bowls and plates, for turning beds, coves
and other detail (Fig 14).
Fig 14
Scraper (B, Fig 13), used for diameter scraping and to
reduce ridges.
Skew Chisel (C, Fig 13), used to make vees, beads, etc. (Fig
15). The bevel of skew is parallel to the cut.
Fig 15
Parting tool (D, Fig 13), used to cut directly into the material,
or to make a cut off. Also used for scraping and to set
diameters.
6.3 Speed selection:
Use low speeds for roughing and for large diameter work. If
vibrations occur, stop the machine and correct the cause.
See speed recommendations.
