Recommended Frequency
Once every 3 months
Notes: In order to avoid the breakage of the glass laser tube due to the heat generated during laser excitation and water pump clogging, it is necessary to maintain the water-cooling effect with sufficient distilled water.

Preparation Items
Self-preparation:

7|Funnel
Maintenance Steps
0. Unlug the power
- Turn off the machine and unplug the power cord before changing or adding water.
- Use a Torx screwdriver to remove the two screws on both sides of the back cover, then lift the cover.
- The laser tube has two ends: the high-voltage side is near the screen, and the low-voltage side is near the reflective mirror.
- If the water is not overly dirty, you can skip steps 1 and 2. However, remember that the optical path must be realigned after moving the laser tube.
1. Disconnect the laser tube wires
a. Press the white terminal and pull out the ground wire (Photo above).
2. Remove the laser tube holders
Use a 3mm Allen key to loosen a total of 4 screws on the laser tube holders (Photo below).
3. Remove laser tube to drain water out
a. Place a towel or paper towel underneath the laser tube in case of leakage (Mind the laser tube's position and angle) > Move both pipe clips away from the hose connector with the needle nose pliers > Remove the joint from one of the hoses and immediately insert the hose plug > Repeat the same for the other hose >
b. Drag the longer hose to the bottom side (High-voltage side) of the machine and put the opening into the water container > Remove the hose plug to drain water (When the water outlet at the Low-voltage side is lower than the High-voltage side, the water will drain due to the Siphon Phenomenon) >
c. Lift the laser tube to drain the water completely. (Skip this step if choosing not to move the tube.)
4. Place the laser tube back and put it on the hose
a. Place the laser tube in position as in the photo above (Skip this step if choosing not to move the laser tube.)
b. Remove the plug at the High-voltage side and put on the hose.
c. At the Low-voltage side. Put the clip on the shorter hose > Remove the plug > Insert the joint on both hoses > Move both clips closer to each other to prevent leakage.
5. Connect the ground wire of the laser tube
a. To the Low-voltage side > Press down the white terminal and insert the ground wire > Release the white terminal > Gently pull the ground wire to check if it is firmly connected.
6. Fix the laser tube holders
Make sure the distance between the laser tube and the first reflective mirror is around 15mm (One finger's distance)
7. Power cord and start-up
Plug the power cord and turn on the machine.
8. Water pump take out

9. Water Filling
Open the cap of the pump with a double head wrench > Put in the funnel > Pour the water in slowly and keep it 50% full > Go to "Maintain Mode" and wait until it finishes homing > Press the "Pump" button to turn the water pump > When water tank's water decreases, pour in more water until the tank is 80% full.
10. Close the Water Pump Cap
Put back the pump's cap and tighten it with fingers only > Place the water pump back in position.
11. Reassemble the Plate
Fix the plate back by tightening these 4 screws with a Torx screwdriver.
