(The power control box has two hanging rings.)
（2）The power control box on the ground can be moved.
！Note
Transportation of work liquid tank
（1）Use a forklift to move it.
（2）When the work liquid tank is on the ground, you can use hands to push
the work liquid system.
Hanging ring
Hook the hang
rings to move
the power control
box.
＊ When the power control box is moved on the ground,
the ground should be even and without any obstacles.
＊ For pushing the power control box, there should be
one man before and behind the power control box so
as to avoid losing center of gravity, or the power control
box may overturn.

2.4 Machine installation
（1）Power supply and wire connection
1. It would be better to prepare a voltage stabilizer for the power required
by the electric control box. It is necessary to have a protective measure
for your machine before installation.
！Note If the voltage fluctuation in your area is over + 10%, it is
necessary to install a voltage stabilizer to protect the
controller, and ensure a normal function with the circuit
board. It is to prevent the machine from being damaged.
2 . The machine must be grounded. It is better that the operator stands on
a wooden stand to operate the machine.
3. The wire connection of the machine is as following figure shown.
Please connect the electric control box and the wires according to the
instructions.
！Note Do not connect the auto fire extinguisher to the electric
control box in parallel so as to avoid error action on safety
functions.

（3）Level the machine
1 . There are 5 level bolts under the adjusting base.
Use a wrench to turn the level bolts, and level the
machine.
2. Measure again and again till the machine is
practically leveled.
（4）Remove anti-rust oil
During the storage and transportation, some
components and the hand scraping surface of the
parts needs to be covered with one layer of
anti-rust oil. Before using the machine, it is
necessary to degrease them by kerosene, gasoline
or methyl benzene. After removing the anti-rust oil,
please feed following lubricant or same grade
lubricant to the machine.

2.5 Check before start the machine
1. Check power
Before starting the machine, please verify if the input power agrees with the
rating power labeled on the electric control box.
2.Check the electric control box
If the machine arrived through a long transportation, please ask the
installation technician to open the front and the rear doors of the electric
control box, and check if any of the contact is loose.
3. Check the connecting wire
Verify if every wire is connected to correct position as labeled.
4. Verify the removal of the shipment blocks
There is one fixed block to lock X axis and Y axis respectively. It is to
prevent X axis and Y axis moving during transportation. Before you switch
on the power, please verify these blocks are removed.
5. Check if oil can enter every oil pipe of the oil feeder
6. Check the pipe circuit of work liquid
A: Close the two doors of the oil trough. Check if the door catch is clasped.
B: Check if the oil trough and the tube harness of the oil tank are tightened.
C: Fill oil to the oil tank and the pump. Close all the oil spray valves. Then,
you can switch on power.
D: Switch on power, and start the machine in order. After completing the
start procedure of the machine, press PUMP ON, and verify if the pump
rotates in arrowheaded direction.
E: Check if the pressure valve of the oil trough reaches 20 KGS (When
input 380V to motor, the oil trough reaches 30 KGS) . Please also check
if the filter barrel leaks oil.
F: Check the oil spray valve.
G: Check the oil sucking valve.
H: Check if the door of the oil trough leaks oil.
I: Check if the surroundings of the oil trough leaks oil.

3. Safety Directive
-1- 1
3. Safety Directive
The work liquid used in EDM will sparkle and produce high temperature
during work. Therefore, following regulations must be strictly followed.
1. Safety Device and its installation
Do not remove or modify any of the safety devices without permission
when you operate the EDM.
（1）power : EDM should have an independent power supply. Do not
share a circuit breaker with other machines.
（2）Liquid level sensor: when the level of the work liquid is lower than
the setting, the machine will stop working immediately, and sends
out a warming.
（3）Fire prevention sensor: When fire alarm happens during work, the
machine will stop working immediately, and sends out a warming.
（4）Fire extinguisher : when the work liquid is on fire, the auto fire
extinguishing device will spray fire-extinguishing chemical
automatically.
（5）Temperature control switch ( limited to the machines with CE mark) :
Please set 50℃for the work liquid. If the temperature is over 50℃,
the machine will stop working immediately. 8
（6）The switch of oil trough door (limited to the machines with CE
mark): if the door of the oil trough is open, the machine cannot
work.
2. Environment
Be sure to clean the surroundings of the machine frequently
（1）Avoid harm to the operators
a. The work liquid is one kind of corrosive liquid. It will make human
skin allergic. Suggest the operators to wear work gloves, or
spread hand ointment. Suggest the operators to wear gloves, or
Spread hand care ointment.
b. The work process will produce harmful gas to operators. Please
install an exhaust pipe to exhaust the waste gas during the work.
（2）Avoid polluting environment
a. Avoid work liquid leak
b. Prepare a non-leaking floor.
