PREFACE
Thank you for purchasing our lathe to be your production machine. Before
operating the lathe, it is necessary to study our manual. If user can operate correctly,
the machine is efficient and easy-to-operate.
This manual consists of 7 chapters, mainly including operation, maintenance and
list of spare parts. Please read the manual thoroughly from the first page to the last in
order to be familiar with this machine to work efficiently and effortlessly. Besides,
based on safety consideration, the operator must be well trained according to all the
instructions in the manual. Any damage of the machine and injury on the worker
caused by improper operation and disregard of our instruction is not covered under
warranty.
In addition to the instructions listed in our manual, there are some matters needing
attention as well:
1. Do not expose the machine to outdoors in order to avoid any damage caused by the
weather and must keep the machine away from cooling wind.
2. Lubricate the machine with recommended or specified lubricant or grease.
3. Remove chips frequently to keep the machine clean, this will make the machine
last longer.
4. If machine’s bed way is dented, please do not move the carriage until the bed way
is repaired.
If you have any question, please do not hesitate to contact your local
distributor!

ELECTRICAL CIRCUIT CONTROL
2-1 Electrical Wiring
1. The electrical control cabinet is located at the back side of headstock. Opening the
cabinet cover and connect the power source wires to the terminals (R, S & T)
The wires between the power source and the terminals must have over sectional area of
21.2mm2for 230V (8.4 mm2for 480V on 30HP
spindle motor).
2. The main power switch between the machine
and the power source also should be equipped with
safety fuses. Also the machine must have a ground
wire.
Fig. 2-1
2-2 Electrical Equipment
1. The electrical cabinet is also equipped with overload circuit breakers and electric
magnetic contactors to protect motors from overload during excess heavy cutting.
2. The forward/reverse switch is connected with micro switch.
3. The foot brake is connected with micro switch. Stepping the footbrake is quicker
to stop the lathe than turning off the main power switch. The spindle can only
rotate again by resetting and operating the spindle operation control lever after
releasing the foot brake.
4. The spindle will rotate continuously as long as the jog button on the top of the
electrical control panel is pressed.

2-3 Electrical Cautions
1. After wiring, check the rotation of the spindle of the spindle. Turn the main
power switch “ON” and make sure the spindle is safe to turn. Then push jog
button (T) momentarily. The correct direction of the spindle rotation is counter
clockwise. (looking from tailstock end and have a downward movement of the
spindle operation control lever.) Wrong direction of the rotation can be corrected
by interchanging any two of the three phase lines (R.S.T.) in the power source.
2. Checking each lubrication system’s oil level.
3. Checking each handle if it is function normally.
4. Checking belt tension adjustment to see if it is in good condition.
5. Read and understand each section of the lathe before operation.
6. When power indicator is “ON”, but spindle motor is not running. Overload
circuit breaker and electric magnetic contactor have act to protect motor from
overload, please reset the circuit breaker by press the reset toggle and lathe will
be able to operate again. (The electric wiring attached at chapter 2-4)
