2. Unpacking and Installation
2-1 Points for Unpacking
For short distance transportation of this machine, fix it onto the truck by hemp rope:
while for long distance, packed by a wooden case or dispatched by container. Please
first to check if there is any damage on packing when arrive. After unpacking
carefully inspect whether it exists any injury or insufficiency. If any contact us
immediately for proper settlement or any of the damages of the machine will receive
no any compensation from us.
2-2 Unloading of the Machine
When the machine is unloaded from the car or to be moved, please proceed with
following steps (as illustrated 2-2)
1) Preparing two round sticks (long approx.830mm dia 40mm) insert into the
preserved holes on lathe bed. Then lift up with applying wires on both end of the
stick.
2) Lifting the machine by a crane.
3) Before lifting adjust the position of Lathe Apron and Tailstock to maintain the
balance of machine.
4) When the machine was shifted to its destination. always handle with care to put
it down. Don’t let go of it to hit the ground or it will affect the accuracy of the
machine.
Note: Machine weight can be seen in Specification Table.
5) For the adjustment of electric control, keep the distance between machine and
wall not less than 600mm.

2-3 Construction of the Ground
Due to the recent tendency of
utilizing Utilizing Ultra-Hard Alloy
Steel tools, it surely increase the
speed of heavy cutting comparing to
the previous steel tools. But, in the
mean time, it easily happens to the
vibration of the machine. For assuring
better cutting result, it requires a very
strong and steady construction of
ground. (Please refer to right
illustration of construction of ground)
2-4 Cleaning
All our machine are with a anti-rust
oil layer before delivery. After inspection, please remove to clean the slideways, lead
screw, shafts and other polished parts by a soft cloth with cleanser (do not use
gasoline or cellulose solvent to avoid fire or explosion). Then apply a thin layer of oil
for lubricating purpose. Push those movable parts such as: Tool Holder, Tailstock back
and forth.
2-5 Level Adjustments
Wait until the fixture screws and cement completely concrete to start adjusting lathe
bed horizontally. In doing this, place a leveling instrument (with accuracy 0.02 mm/
1000mm) upon the grooves of lathe bed to confirm the level of right and left side.
Same procedure for the front and rear leveling.
The allowance of level should be adjusted within 0.04
mm/ 1000mm.
Screw up the nuts, check again, if
whatever errors occur due to tightly
screw-up thereinafter, adjustment may
require to be done again.
As per illustration indicated, place
two leveling instruments on lathe bed to
check the level by pushing them back
and forth in its possible maximum
moving range.

3. Electric Circuit Control
3-1 Electric Wiring
You can find the electric control box by open the metal cover behind the lathe bed.
Connect the terminals “R”,“S” and “T” to power source. Note that the specification of
the electric wires must be above 8 sqr. mm of its cross section area. Power switch of
the machine and power source should be with fuse and the machine ought to be
grounded.
3-2 Electric Device
1) The electric pannel is equipped with cut-off device and solennoid contactor for
avoiding from overloaded breakdown of motor.
2) Tumbler Rotation Switch connect with Micro Switch.
3) Foot brake is connected with micro switch, braking prior to the manually starting.
Whenever you release the foot brake, you need to re-operate Spindle Control Lever
again to resume the operation of main spindle.
4) On top of the control box, there exist a “INTREMITENT” button for in-
termittent operation of the spindle.
3-3 Important Notes
**Check the rotating direction of spindle after wiring:
1. Turn on the power switch.
2. Slightly push “INTREMITENT” button.
3. Look at the rotating direction of Main Spindle from Tailstock.
4. If it is of anti-clockwise, you’ve got a right wiring.
5. If oppositely, exchange any of two wires among “R” “S” “T” terminals.
**If the power indicating lamp is on but you can not start the motor. Thus, it is
overloaded.
If it happens the current out of limit, the cut-off device will activate immediately. In
this moment, please turn off the power then press slightly the recovery plate near
cut-off device in the control box. It will work again. (electric circuit program as
illustrated on next page)

4-2 Transmissions and Stop of Main Spindle
You can start test run when you follow the previous steps as illustrated by the
Manual. Position the High/Low Speed Lever (2) in “L”, Main Spindle Speed Change
Lever (3) in left position, Forward / Reverse Lever (4) in the middle of “N” position.
Turn Start Lever (11) Right and push down to rotate obversely the spindle; pull up to
rotate reversely. By using Spindle Control Lever to operate the machine in normal
condition, use brake when it
needs to stop in emergency.
Naturally, in this case, you
need to push the Spindle
Control Lever again in the
middle position to re-start the
Spindle.
Turn on Pump switch (10)
to start pump. Adjust Valve
(33) is used for adjusting the
required quantity of cooling
water.
4-3 Selecting Main Spindle Speed
The speed of main spindle is consisted of 3 speed change lever, i.e. Speed Change
Lever (1), High/Low Speed Lever (2) and Main spindle Speed Select Lever (3) to
perform 12 speed change. When you shift High/Low Speed Lever (2) to the neutral
position in between “H” and “L”, you can rotate the Main Spindle only with you
hands. For the safely
reason and not to injure the
gear every speed change
must operate in the time
while motor stops. If the
teeth of the gear can not be
properly engaged, push
“INTERMITENT” button
(9) then shift Speed
Change Lever (1)(2) or (3)
to change the rotating
speed.
CAUTION: DO NOT CHANGE SPEED WHILE SPINDLE IS RUNNING.
BE SURE ALL GEARS ARE PROPERLY ENGAGED BEFORE
STARTING.

4-4 “INTERMITTENT” Operation of Main Spindle
For the convenient way of
changing Main Spindle
Speed, confirming Feed
Speed and Centering objects,
the machine equipped with
“INTERMITTANT” button
(9) located in the right side
of Gear Box. Push it down,
Main Spindle will
immediately rotate forward;
and if to release the button, it
stops. Note that the intermittent function cannot rotate reversely.
4-5 The Importance and Methods of Spindle LevelingAdjustment
1) Switch on to make the Spindle turn while the Spindle is set up at 1330 r.p.m. By
putting the palm of the left hand on the Headstock cover to fell its chat ter. An
unlevelling Spindle will lead to lathe chatter. Move Leveling Block (either “A” or “B”)
left or right to adjust until your left hand feels the minimum chatter.
2) Afterwards, change the Spindle speed to 2000 r.p.m. or 900 r.p.m. and check the
Leveling with the same way as we did at 1330 r.p.m. by adjusting the Leveling Block
“A” or “B”.

4-6 Transmissions and Stop of Gear Box
Open the end side cover of Headstock, you will find a gear train transmit the power
from Headstock to Gear Box. Shift Forward/Reverse Lever (4) to right side, it runs
forward, or to left side, reversely, or it stops if you shift it to the middle position.
Never change speed while machine is running.
4-7 Operation of Gear Box
1. Cutting Threads
A special designed gearbox, you need not to use back gears to proceed threading.
Please refer to gearbox cutting feed table and shift to appro preate Thread Feed
Select Lever (5)(6)(7) respectively then you may obtain required specification.
2. Auto Feed
The selection of Auto Feed should be coordinated with the cutting speed and feed
speed. Please refer to cutting table and select proper feed speed and follow the
instruction plate to shift thread Feed Select Lever (5)(6)(7).
4-8 Manual Operations
Firstly shift the Half Nut Engaged Lever (18) of Apron and Forward/Reverse Lever
(4) to “N” position, then you can arbitrarily operate Longitudinal Apron Hand-wheel
(13) Cross Slide Handle (14) and Compound Rest Hand-wheel (32). It feeds 17mm
per revolution of Apron Hand-wheel. The dial on Cross Slide and Compound Rest is
graduated 0.02mm per division and feeds 4mm per revolution.
Release Tool Post Clamping Lever (36) and you can revolve the Tool Post
anticlockwise then fix it. In order to lock the Apron, only screw up the Saddle Set
Screw (20). If there is any backlash in between Cross Slide and Compound Rest, just
to screw up the set screws on the both ends of the sloping plate.
