4. Unpacking and Installation
4.1. Unpacking
Unload the machine with a tackle, using clamping plates and eyebolts. Keep the
machine in balance by moving the tailstock and the bed slide to the right. Avoid using
sling chains as they could damage to feed rod and leadscrew. Lift the lathe carefully and
place it softly into the floor or workbench.
4.2. Cleaning
Before taking the machine into operation, using kerosene (paraffin) or white spirit to
remove the anti-corrosive coating or grease from all slideways and gear train. Don’t use
lacquer thinner or other caustic solvents. Oil all bright machine surfaces immediately after
cleaning. Use heavy oil or grease on the change gears.
4.3. Installation
Place the lathe on a solid foundation. A concrete floor is the best base for the
machine. (If necessary, use an under frame operational). Make sure there is sufficient
area around the lathe for easy work and maintenance. Use a precision level on the
bedways to make further adjustment for level condition, then tighten the foundation bolts
evenly and finally recheck for level condition.

5. Lubrication
Before putting the lathe into operation, make the following lubrication check.
5.1. Headstock
The bearing of the headstock turns in an oil bath. Ensure that the oil level reaches
three quarters of the oil gauge glass.
For exchanging the oil, remove the end cover and the change gears with swing frame.
Drain off the oil by removing the drain plug on the bottom of the headstock. To fill, take off
the headstock cover.
Check the oil level regularly. The first oil change should be made after 3 month, then
change it once a year.
5.2. Gearbox
Remove the end cover to expose the filling plug. Through it the Shell is filled to the oil
level in the oil gauge glass regularly. The first oil change should be made after three
months, then change it once a year.
5.3. Apron
The oil bath is filled with Shell through the filling plug on the right side of the apron.
Check the oil level in the oil gauge glass on the front regular. The first oil change should
be made after three months, then change it once a year.
For exchanging the oil, drain away oil by taking off the drain plug on the bottom of the
apron.
5.4. Change gears
Lubricate the change gears with thick machine oil or grease once a month.
5.5. Other parts
There are other lubricating points on the input shaft bracket of the gearbox, the
handwheel on the apron, the longitudinal and cross slide, the thread dial indicator, the
tailstock and the bracket, use the grease gun to put a few drops of oil from time to time.
Lubricate the apron worm and worm gear, half nut and leadscrew twice a month. Apply a
light oil film to the bed way and all other bright parts like the tailstock quill, feed rod etc.
once a day.

6.2. Spindle speed control
(A). Identification before operation
Ensure that lubrication has been carried out as described before.
When the main spindle is rotating. The gearbox and feed axis of the bedsides are put
into operation. The forward/reverse switch should be on neutral. The feed axis selector
and feed/thread selector handle are in disengaged position. Under these circumstances,
both the longitudinal traverse handwheel and cross traverse handle can be operated by
hand.
(B). Main spindle rotation
The main spindle rotation is selected by forward/reverse switch.
(C). Main spindle speed
The speed of the main spindle is selecting by (high/low) speed selector (2) and 4
steps speed selector (4). For both high and low speed, there are 4 different positions. For
correct speed, please refer to the speed chart. When selector (2) is on “high”, we can get
the four speeds, according to the graph.
Never change the speed before the motor has stopped completely!
Adjusting the speed can be assisted by turn the main spindle by hand.
(D). Running-in
Running in should be done at lowest possible spindle speed. Let the machine to run
at lowest speed for about twenty minutes, and then check for irregularities. If everything
seems in order, gradually increase the speed.
(E). Operation
Use only high peripheral speed type chucks.
The maximum spindle speed for chuck plate of 255mm diameter should not be more
than 1255r.p.m. When thread cutting or auto feeding are not in use, the feed/thread
selector should be in neutral position, so as to ensure disengagement of the leadscrew
and the feed rod. To avoid unnecessary wear, the thread dial indicator should be out of
mesh with the leadscrew.

7. Thread and Feed Selection
7.1. Thread and feed selection
All feed and threads are given on the feed thread tables, fitted on the front and inside
of the gear box cover (35), by setting the four feed selector handles (31),(32),(33),(34).
(A). Hand feed operation
The movement of carriage is made by the longitudinal traverse handwheel (9), cross
sliding by the cross traverse handle(12), and compound rest by the compound rest
traverse handle (15), the carriage is anchored by turning the carriage lock screw in
clockwise direction.
(B). Replacement of change gears
Take off the gear box cover(35)firstly, and then loosen clamping shaft and the
clamping screw of the swing frame to exchange the transmission shaft gear with another
gear, it is necessary for suitable back lash to intermediate the gears in both cases.
Change gear’s assemble style have 3 kind: F, G, H. F, G assemble style be used for
feed and metric thread, imperial thread cutting. H assemble style be used for MP thread,
DP thread cutting. F assemble style be used on machine for leave factory.
For any special threads not covered by the thread table, our engineering department
is available to specify the most convenient change gearing required.
(C). Automatic feed operation and change
When the feed axis selector (13) on the apron is pulled out and operated upward, we
can obtain a longitudinal feed and cross feed can be obtained by pushing the selector in
and operating it downward. (Make sure the thread cutting engagement lever (16) at
disengaged position before operating the feed axis selector.)
Feed direction can be changed by turning feed direction selector . It have 24 kinds of
feed speeds each in longitudinal and cross feed can be obtained by means of the feed
selector handles.

7.3. Thread cutting operation
In order to obtain the desired thread, all correct change gears must be installed in
strict accordance with the chart, failure to do so will give incorrect threads.
Rotate the leadscrew by operating the feed/thread selector to any position and be
sure the feed selector handle is engaged. Operate downward the thread cutting
engagement lever (16), and it will be engaged with the leadscrew to obtain the
longitudinal travel of carriage, namely, the thread cutting feed. Make sure the feed axis
selector is disengaged (at neutral position) before operating the thread cutting
engagement lever (16) since there is an interlock mechanism between the auto feeding
and thread cutting engagement.
Direction of thread cutting can be chosen by turning the feed directing selector (36) at
the headstock. There are 42 Nos. of thread pitches each in Imperial, 44 Nos. of Metric
pitches,34 Nos. of module thread , 5 Nos. of diametral thread those which can be
obtained by turning the feed selector handles .
(A).Thread dial indicator
The thread dial indicator is installed on the right hand side of the apron; the indicator
is used for thread cutting to engage with the leadscrew.
For minimum wear the thread dial indicator should be disengaged by swing the pinion
out of mesh with the
leadscrew when not in
use.
