other objects at the rear to assure of good ventilation.

Figure2.1.1

2.1.2 Connections with Power Cables and Wires

Install the device near an outlet for AC 220V to connect it.

.

Figure2.1.2
2.1.3 Connections with Foot Switch

Put the foot switch into round-shaped 3-pin connector in the

2.2 How to Install

2.2.1 Articulated Arm Attachment

Insert the articulated arm referring to the pictures as below;

Figure 2.2.1 ① Figure 2.2.1. ② Figure 2.2.1.③

① Hole a longer arm section as a vertical axis and insert a thread part of the arm at right angles.

② Turn the screw holder to the left tightly.

③ When screw the part, keep the balance shaking the arm slightly. It causes not to be combined
with laser beam and aiming beam, and lower power that the arm is unbalanced.

Figure 2.2.1④

④ Put a silicone air hose to nozzles that are at a handpiece and a main console as pictures.

2.2.2 Foot Switch

Insert the cord for the foot switch into 3 pin

connector located on the rear panel and screw the
holder to the right. It causes not to be emitted that
user presses the foot switch only one side slightly.
It should be pressed the middle of the foot
switch.(Figure2.2.2)

Figure 2.2.2

2.2.3 Main Power Cable

Insert the main power cord into 3 pin(Figure2.3) connector.

2.2.4 Fuse Holder

Two fuse holders are located between the main connector and footswitch connector(250V/5A).
These break the electric supply automatically when an electric accident is occurred.

•Chapter 3. CO2 Tube Alignment

3.1 Alignment
Remove the articulated arm from the arm mount and rear panel.

① Connect foot switch and turn on the device. Press

CW button and power up to 10W.

② Cover a test paper that can be well shown the red .

aiming beam on the arm mount, and then press the
foot switch to emit the laser.

Figure 3.1.②
③ If the red aiming beam not be combined with
burning point with laser, turn a adjustment bolt ⓐ
and ⓑ to move laser beam till the laser beam ⓐ ⓑ
combine with the aiming beam

Note: The adjustment bolt ⓐ in front of tube makes

the laser move up and down and the ⓑ side of
the tube, right and left.
Figure 3.1.③

④ Recover the test paper and you can see the red
aiming beam on the ceiling. The distance between
the arm mount and the ceiling should be 1(one)
Meter or more.

⑤ Press the foot switch to emit the laser on the ceiling.

⑥ If the red aiming beam not be combined with Figure 3.1.④

burning point on the ceiling, turn an adjustment bolt
ⓒ and ⓓ to move laser beam.

ⓓ
Note: The coin bolt ⓒ in front of tube makes the laser
move up and down and the ⓓ side of the tube, ⓒ
right and left.

•Chapter 5. Replacement

5.1 Control Board Replacement

Remove front and rear panel of device and turn it on.

① Press SP button to displayed 3W power.

② Remove 3(three) nuts on the board, and separate

it to push the board from under the board. And
then you can see the back of control board.

③ Set a multi-tester to Voltage mode

Figure 5.1.③ Figure 5.1.④ Figure5.1. ⑤

④ Connect red stick of a tester to TP1and black stick to GND. And control the voltage to 2.055V
to turn VR1 / VR10K by “-”driver.

⑤ VR2 / VR20K is a controller of aiming beam. Remove the electronic wire ⓐ, and then turn
on the device. Turn the VR20K to left completely by “-” driver. After that, connect the
electric wire ⓐ. Turn VR20K to right slowly till the aiming beam will be desired brightness.

•Chapter 6. Precautions

A. Due to the laser beam is not combined with the

aiming beam when the articulated arm is loosen,
check the articulated arm when the articulated arm
is loosen and laser power is lower .

B. Don’t grip the articulated arm strongly as the

picture due to the position of 7-mirrors in the
arm are broken away or broken. It is needed
Figure B 5~7days to repair.

C. Don’t push the articulated arm to the back of it.

The arm only moves and leans toward the
front part. It is needed 5~7days to repair.
