Forklift
Fig. 5
• Insert forks under the bed as close to the
headstock as possible.
• Make sure to keep the machine’s center of
gravity spread evenly across the forks.
1700 Series Lathe
Read and understand the entire contents of this
manual before attempting set-up or operation.
Failure to comply may cause serious injury.
Confirm that all suspension equipment is properly
rated and in good condition for lifting lathe. Do not
allow anyone beneath or near load while lifting.
7.0 INSTALLATION
1. Finish removing all crate material from around lathe.
2. Unbolt lathe from shipping pallet.
3. Choose a location for the lathe that is dry and
has sufficient illumination (consult OSHA or ANSI
standards for recommended lighting levels in
workshop environments).
4. Allow enough room to service the lathe on all four
sides, and to load and off-load work pieces. In
addition, if bar work is to be performed, allow enough
space for stock to extend out the headstock end. If
used in production operations, leave enough space
for stacking unfinished and finished parts.
5. The foundation must be solid to support the weight of
the machine and prevent vibration, preferably a solid
concrete floor.
6. The lathe’s center of weight is near the headstock.
Before lifting, move the tailstock and the carriage to
the right end of the bed and lock them.
7. With properly rated lifting equipment, slowly raise
lathe off shipping pallet. (see Figure 6). Do not lift
lathe by the spindle.
8. The lathe can be placed upon the cast iron leveling
pads under each foot hole, and adjusted using the
adjusting bolts with hex nuts. Or, it may be secured
to the floor using bolts placed head-down in the concrete, and using shims where needed to level the
machine. Refer to Figure 1 for mounting hole dimensions.
7.1 LEVELING THE LATHE
It is imperative that the lathe be on a level plane; that is,
where headstock and tailstock center points remain aligned
throughout the tailstock travel, with the bed ways absent of
twist and thus parallel to the operational center line.
A lathe which is not properly leveled will be inaccurate, producing tapered cuts. Also, the center point of the tailstock
will vary as it is positioned along the bed, thus requiring
constant readjustment.
9. Use a machinist’s precision level on the bed ways
both front to back and side to side, as shown in Figure 7. Take the reading in one direction every ten
inches. Make sure the ways are clean and free of any
debris before placing a level upon them.
10. Deviation over bed length (see Figure 7):
(a) Maximum 0.02/1000mm
(b) Maximum 0.04/1000mm
EGH1740 | EGH1760
Fig. 6
Fig. 7
11
11. Tighten foot screw nuts evenly to avoid distortion.
12. Leveling should be inspected occasionally, and
especially if the accuracy of the lathe begins to
diminish.
7.2 CHUCK PREPARATION
Read and understand all directions for chuck
preparation. Failure to comply may cause serious
injury and/or damage to the lathe.
Chucks are heavy; use an assistant to help remove.
The three-jaw scroll chuck is shipped pre-installed on the
lathe. It can be used for clamping cylindrical, triangular and
hexagonal stock, and has reversible jaws.
The four-jaw chuck has independently adjustable jaws,
and permits the holding of square and asymmetrical
pieces. It also enables accurate concentric set-up of
cylindrical pieces.
diameter of chuck, for easier installing and removal. Figure
8 shows an example.
To remove a chuck from the spindle:
1. Support the chuck while turning six camlocks 1/4turn counterclockwise, using the chuck wrench from
the tool box. See Figure 9.
2. Carefully remove the chuck from the spindle and
place on a firm work surface. If the spindle seems
stuck, use a mallet at various points on the back
side to help free it from the spindle.
3. Inspect the camlock studs. Make sure they have not
become cracked or broken during transit. Clean all
parts thoroughly with solvent. Also clean the spindle
and camlocks.
4. Cover all chuck jaws and the scroll inside the chuck
with #2 lithium tube grease. Cover the spindle, camlocks, and chuck body with a light film of 20W oil.
5. Lift the chuck up to the spindle nose and press onto
the spindle. Tighten in place by turning the camlocks
1/4 turn clockwise. The index mark (A, Figure 9) on
the camlock should be between the two indicator
arrows (B) when tight, as shown in Figure 9.
• If the index mark (A) is not between the two
arrows, i.e. the cam turns beyond the indicator
arrows, then remove the chuck and turn the
camlock stud IN one full turn.
• If a camlock will not engage, remove the chuck
and turn the camlock stud OUT one full turn.
6. Make sure chuck is secure on the spindle with the
camlocks correctly engaged.
Fig. 8
Before removing a chuck, place a flat piece of thick
plywood across the bedways under the chuck to prevent
damage to the bedways should the chuck fall from your
hands. Alternatively, many users make a wood chuck
cradle that sits atop the ways and accepts the specific

7.3 CHUCK AND CHUCK MOUNTING (FOR D1-6 SPINDLE)
Use only high-speed chucks with these machines.
Reference mark on spindle nose and chuck
A
C
Cam release datum
Turn stud out one turn
When fitting chucks or faceplate, ensure that spindle and
chuck tapers are thoroughly cleaned and that all cams lock
in the correct positions the first.
It may be necessary to re-set the camlock studs (A) when
mounting a new chuck. To do this, remove the hexagon
socket 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 hold.
Now mount the chuck or faceplate on the spindle nose and
tighten the six 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. A reference mark should
be made on each correctly fitted chuck or faceplate to
coincide with the reference scribed on the spindle nose.
This will assist subsequent remounting.
Note: Do not interchange chucks or faceplates
between lathes without checking for correct cam
lock.
Take careful note of speed limitations when using
faceplates; 12 inch faceplates should not be run
at speeds higher than 1000 rev/min. and 14 inch
faceplates should not be run at speeds higher
than 770 rev/min.

7.4 LUBRICATION CHECKS
Headstock/Gearbox/Carriage, Apron/Tailstock
Before operating the machine, make the following
important checks:
• The headstock is filled to the correct level with 11.5
liters of R-32 oil, or equivalent. Check oil weekly and
change the oil every 6 months.
• The gearbox is filled to the level marked on the oil
sight window with 1.8 liters of R-68 oil, or equivalent.
Check oil weekly and change the oil every year.
• The carriage apron is filled to the level marked on
the oil sight window with 1.8 liters of R-68 oil or
equivalent. Check oil weekly and change the oil
every year.
• In addition, using an oil can, apply oil to the points
shown on lubrication diagram which require daily
oiling. Use light machine oil or way lubricant.
• Before each working shift, operate the one shot
lubrication pump to ensure adequate lubrication of
carriage slideways.
A manually operated one shot lubrication pump (A) is
incorporated into the apron. It enables the operator to
ensure that the slideways are kept adequately lubricated.
The pump should be operated before and occasionally
during the work period.

8.0 ELECTRICAL CONNECTIONS
Electrical connections must be made by a qualified electrician in compliance with all relevant
codes. This machine must be properly grounded
while in use to help protect the operator from electrical shock and possible fatal injury.
Push during working
Fig. 11
Oil can be added or drained via hex drain plug located in
the bottom plate of the apron.
In addition to the one shot lubrication, oiler points are
provided for the saddle cross-slide and cross-slide nut.
Use a standard oil can with light machine oil or way
lubricant.
On the tailstock and tail end of leadscrew, lubrication
points are provided for daily attention from a standard oil
can.
It is recommended that all slideways, the leadscrew and
feed shaft are cleaned daily and then lightly lubricated.
7.5 COMPLETING INSTALLATION
13. Exposed metal surfaces have been coated with a
rust protectant. Remove this using a soft rag and
mild commercial solvent or kerosene. Do not use
paint thinner, gasoline, or lacquer thinner, as these
will damage painted surfaces. Cover all cleaned surfaces with a light film of SAE-20W machine oil, such
as Mobil DTE Oil Heavy Medium.
14. Open the end gear cover. Clean all components
of the end gear assembly and coat all gears with
a heavy, non-slinging grease. Close the end gear
cover. (Note: A limit switch prevents the lathe from
operating when the end gear cover is open.)
Confirm that power available at the lathe’s location is the
same rating as the lathe.
IMPORTANT: The lathe must be wired properly
and phased correctly. The spindle should rotate
counterclockwise (as viewed from the tailstock
end) while the feed rod rotates clockwise (as
viewed from the tailstock end). If the phasing
needs correction, disconnect lathe from power
source and switch any two of the three power
leads (not the green ground wire).
Make sure the lathe is properly grounded.

9.3 HEADSTOCK SELECTORS
Spindle speed selector
1. The upper two selectors on the headstock are
for spindle speed selection. There are 16 spindle
speeds, as shown on speed chart, divided into four
groups. Each speed is the result of combining the
above two selectors.
2. For instance, if 1000 r.p.m. of spindle speed is to be
chosen, then move left selector to D, and two-speed
motor switch to low range.
H-N-L selector for gearbox
1. Following each feed rate or thread pitch on gearbox
thread and feed chart, there is a prefix of either H or
L.
2. Move H-N-L selector to H or L accordingly for
feeding or threading. If this lever is positioned at
N, the headstock rotation will not be transmitted to
gearbox.
Apron orientation selector
1. This selector may affect the rotation orientation
of the lead screw, feed rod and henceforth the
movement direction of apron.
2. Right-hand arrow (toward tailstock) is used for
cutting right-hand threads. Left-hand arrow (toward
end-guard) is used for cutting left-hand threads.

Lever (A) is moved down for power operation and up for
manual.
The push-pull knob (B) selects power surfacing (cross
feed) when pulled out, sliding feeds are selected when the
knob is pushed right in. The adjacent push pull knob (C)
controls forward or backward feed direction.
Lever (D) is pressed downward to engage the leadscrew
nut for screwcutting. To avoid undue wear, release the nut
except when thread cutting, an interlock within the apron
prevents inadvertent engagement of levers A and D at the
same time.
Note: Do not use headstock lever for reversing
feeds except during left-hand screwcutting; Use
instead, the apron handle (C).
Feed-trip adjustment: A trip mechanism is incorporated
in the apron, enabling saddle and/or cross-slide to be
fed up to fixed stops. Trip loads can be set high or low by
adjustment of the knurled handwheel (F) on the side of the
apron. The apron handwheel may be disengaged from its
gear train during power operation or when thread cutting
by pulling the handwheel outwards to on other spring-ball
detent.

9.6 THREADING DIAL INDICATOR
For threads cutting:
• Tighten the handnut to retain indicator in when
engaging the indicator with the leadscrew. When not
required, release hand-nut and swing indicator out of
engagement.
• To cut threads with an even number per inch, the
leadscrew nut can be closed as any line on the dial
passes the datum mark.
• To cut threads with an odd number per inch, close
the leadscrew nut at any NUMBERED line.
• Fractional threads of 1/2 or 1/4 T.P.I. may be cut by
closing the nut at the SAME NUMBERED LINE on
each pass of the tool.
• This dial can not be used with an IMPERIAL
leadscrew to cut metric threads, D.P., M.P. which are
shown on gear box data plate. For the threads being
shown, the leadscrew nut must be kept closed. Use
apron control lever after each thread cutting when
the tool is withdrawn to original start of thread cutting
operation.

(Gear 28T/22T for Metric leadscrew)

Multi-start threads can be cut on a lathe in three ways:
1. By repositioning the compound (top) slide one pitch
forward for each start. Note that the slide is normally
set at 90º to the axis of the machine cross-slide. The
accuracy of this method depends upon the skill of
the operator.
2. By using an accurately divided driver plate and
turning the work-piece one division forward for each
start.
3. By advancing the driver gear a calculated number
of turns to advance the spindle by one pitch of the
thread to be cut. The accuracy of this method is
that of the machine.
• With all series lathes, two ratios exist between
the spindle and driver gear shift, i.e. the LOW
range where the ratio is 1:2 and the HIGH range
where the ratio is 2:1
• In order to use this method, the number of
teeth on the driver gear must be divisible by
the number of starts being cut. The driver gear
is then advanced by half this number of teeth
when in LOW range. And conversely, by twice
the number of teeth when in HIGH range.
• On the standard end gear train for this machine
the driver gear has 24 teeth; so that two, three
or four start threads, can readily be cut. For
other odd numbers of start a choice must be
made of methods 1 or 2.

9.7 CROSS SLIDE AND TOP SLIDE
• A solid topslide is fitted as standard equipment to
the cross-slide mounted on a swivel base which is
marked 0-90-0-90º for accurate indexing.
• Handwheel dials are graduated in inch or metric
divisions to suit the operation.

9.8 TAILSTOCK
• The tailstock can be freed for movement along the
bed by unlocking the clamp lever (A).
• Additional clamping may be obtained by tightening
the large nut (B) located in a recess below the
handwheel.
• Release this clamping nut before attempting to move
the tailstock or completion of the job that required
the extra clamping.
• The tailstock barrel can be locked by lever (C).
• The tailstock also can be offset for turning shallow
tapers or for realignment.
• Release the clamping lever (A) and adjust screw (S)
at each side of the base to move tailstock laterally
across the base.
• An indication of the offset is given by the datum
mark (D) at the tailstock end face, as picture shows.
• Tighten clamp lever after adjusting offset.

9.9 END GEAR TRAIN
1. Drive from headstock to gear box is transmitted
through a gear train enclosed by the headstock
end guard. Intermediate gears are carried on an
adjustable swing-frame (M).
2. Gears must be thoroughly cleaned before fitting and
backlash must be maintained at 0.005” (0.127mm)
for correct meshing.
3. Lubricate gears regularly with thick oil or grease.
