3. Replace the warning labels if they become obscured or removed.
4. This lathe is designed and intended for use by properly trained and experienced personnel only. If you
are not familiar with the proper and safe operation of a lathe, do not use until proper training and
knowledge have been obtained.
5. Do not use this lathe for other than its intended use. If used for other purposes, JET®, disclaims any
real or implied warranty and holds itself harmless from any injury that may result from that use.
6. Always wear approved safety glasses/face shields while using this lathe. Everyday eyeglasses only
have impact resistant lenses; they are not safety glasses.
7. Before operating this lathe, remove tie, rings, watches and other jewelry, and roll sleeves up past the
elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips are
recommended. Do not wear gloves.
8. Wear ear protectors (plugs or muffs) during extended periods of operation.
9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain chemicals known to the state of California to cause cancer, birth defects or other
reproductive harm. Some examples of these chemicals are:
•Lead from lead based paint.
•Crystalline silica from bricks, cement and other masonry products.
•Arsenic and chromium from chemically treated lumber.
Your risk of exposure varies, depending on how often you do this type of work. Toreduce your exposure
to these chemicals, work in a well-ventilated area and work with approved safety equipment, such as
face or dust masks that are specifically designed to filter out microscopic particles.
10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
11. Make certain the switch is in the OFF position before connecting the machine to the power supply.
12. Make certain the machine is properly grounded.

6.1 INSTALLATION
6.2 LIFTING
Use the sling-chain to sling lathe as shown in Figure
5 position the saddle and tailstock along the bed to
obtain balance.
Note: Do not use slings around bed as leadscrew
and feedshaft may be bent.
6.3 CLEANING
Before operating any controls, use white spirit or
kerosene to remove the anticorrosion coating from
all slideways and the endgear train.
Do not use cellulose solvents for cleaning as they
will dam- age the paint finish.
Machine surface becomes bright immediately after
cleaning using machine oil or slideway lubricant.
Use heavy oil or grease on the end gears.
6.4 INSTALLING
Place the machine on a solid foundation, allowing
sufficient area all around for easy working and
maintenance (see Foundation Plan). The lathe may
be used free-standing or bolted to the foundation.
Free-standing: Position the lathe on foundation
and adjust each of the six mounting feet to take
equal share of the load. Then using an engineers
precision level on the bed- ways (as in Figure 7)
adjust the feet to level up machine. Periodically
check bed level to ensure continued Lathe
accuracy.
Fixed installation: Position lathe over six bolts
( M12), set into the foundation to correspond with
holes in the mounting feet. Accurately level the
machine as in Figure, then tighten hold-down bolts
and recheck bed level.

6.5 LUBRICATION CHECKS
Before operating the machine make the following
important checks:
1. That the headstock is filled to level marked
on oil sight window with Shell Tellus Oil 27 ,
Mobil DTE Oil Light (DIN 51517-2 CL ISO VG
32 ) or equivalent.
2. That the gearbox is filled to level marked on
oil sight window with Shell Tellus Oil 27 ,
Mobil DTE Oil Light (DIN 51517-2 CL ISO VG
32 ) or equivalent.
3. That the carriage apron is filled to level
mark on oil sight window with Shell Tellus
Oil 33, Mobil DTE Oil Heavy Medium (DIN
51517-2 CL ISO VG 68) or equivalent.
4. In addition, apply an oil can to the points
shown on lubrication diagram which require
daily oiling. Use light machine oil or way
lubricant Shell Tonna 33, Mobil Vectra 2
(DIN 51502 CG ISO VG 68) or equivalent.
6.6 CHUCKS AND CHUCK MOUNTING
When mounting chucks or faceplate, first, ensure
that spindle and chuck tapers are thoroughly
cleaned and that all cams lock in the correct
positions, see figure. It may be necessary when
mounting a new chuck to reset the
camlock studs (A). To do this, remove the caphead
locking screws (B) and set each stud so that the
scribed ring (C) is flush with the rear face of the
chuck - with the slot lining up with the locking
screw hole (see Fig 10).
Now mount the chuck or faceplate on the spindle
nose and tighten the three cams in turn. When
fully tightened, the cam lock line on each cam
should be between the two V marks on the spindle
nose.
If any of the cams do not tighten fully within these
limit marks, remove the chuck or faceplate and
readjust the stud as indicated in the illustration. Fit
and tighten the locking screw (B) at each stud
before remounting the chuck for work.
This will assist subsequent remounting.
Note: Do not interchange chucks or faceplates
between lathes without checking for correct cam
locking beforehand.
Note: Take careful note of speed limitation when
using faceplate; the 300mm faceplate should not
be run at speeds greater than 770 RPM.

set-over.
8.1 SERVICING AND
MAINTENANCE
8.2 LATHE ALIGNMENT (PART 1)
With the lathe installed and running, we
recommend a beginning check of the machine
alignment before work. Check leveling and
machine alignment at regular periods to ensure
continued lathe accuracy.
Headstock check: Take a light cut with a sharp tool
over 150 mm length on a 50mm diameter steel bar
gripped in the chuck but not supported at the free
end. Micrometer readings at each end of the
turned length (See Figure 22) should be the same.
To correct a difference in readings, loosen the four
head- stock hold-down screws (J) shown in Figure
21 and adjust the set-over pad (K) beneath the
headstock. Then tighten all screws. After
adjustment, repeat the test-cut/micrometer
reading until micrometer readings are identical so
that machine cutting will be absolutely parallel.
8.3 LATHE ALIGNMENT (PART 2)
B. Tailstock check
Using a 300 mm ground steel bar fitted between
headstock and tailstock centers, check the
alignment by fitting a dial-test indicator to the
topslide and traversing the center line of the bar.
To correct error, release the tailstock clamp lever
and adjust the two set-over screws provided.
Continue with checking and correction until the
alignment is perfect.

8.4 END GEAR TRAIN
Drive from headstock to gearbox is transmitted
through a gear train enclosed by the headstock
end-guard. Intermediate gears are carried on an
adjustable swing frame (M).
Gears must be thoroughly cleaned before fitting
and backlash maintained at approximately 0.1mm.
Lubricate gears regularly with non-slinging grease,
e.g. BP L2, Mobilgrease Special, or equivalent.
8.5 DRIVING BELTS
To alter belt tension, remove the coverplate in
back of the headstock and adjust the two screws (X)
on the hinged motor platform. Ensure that the
motor is correctly aligned with the lathe axis.
Light finger pressure at a point midway between
motor and headstock pulleys about 20mm
movement of each belt when under correct
tension.
8.6 SLIDE WAYS ATTENTION
Tapered gib strips are fitted to slideways of saddle
crosslide and top (compound) slides so that any
slack which may develop can be justified.
Ensure that slideways are thoroughly cleaned and
lubricated before attempting adjustment. Then
reset the gibs by loosening the rear gib screw and
tightening the front screw. Check constantly for
smooth action throughout full slide travel; avoid
overadjustment which can result in increased
wear-rate and stiff or jerky action.
8.7 CROSS-SLIDE NUT
This is adjustable for elimination of slack which
may develop in service. Reduce backlash by the
cap-head screw in the rear of the nut, then make
only small adjustments by the cap-head screw.
Before operating the cross-slide, check several
times by hand to ensure smooth operation
throughout travel.

8.8 LUBRICATION (PART 1)
The headstock and gearbox are splash-lubricated
from an internal reservoir of oil (Shell Tellus 27).
Check the oil level constantly to the mark on the oil
sight window in the front end face of the
headstock and gearbox. A weekly check is
recommended. The oil should be changed every
year. Add oil through a filler cap in the top of the
headstock and gear- box is covered by the end-
guard. Drain from a drain plug in the bottom of the
headstock and gearbox.
The apron is lubricated from an internal reservoir
of oil. The oil sight window is in the front of the
apron. A filler cap is in the top of the saddle. Refill
the reservoir to the level of the oilsight with oil
(Shell Tonna oil 33). The apron can be drained by
unscrewing a hexheaded drain plug in the bottom.
8.9 LUBRICATION (PART 2)
In addition, an oil gun is provided for the saddle,
cross- slide, cross-slide nut and top-slide
(compound slide) to oil. Leadscrew using an oil gun
can be oiled with light machine oil or way lubricant.
On the tailstock, oil points are provided for daily
attention from a standard oil can.
It is recommended that all slideways, leadscrew
and feed shaft are cleaned off (a bristle paint brush
is useful for this) and lightly oiled after each period
of work.
Note: Using incorrect grade of oil can cause
damage.
