Recommended Timing
Depending on the power, hours of usage, room temperature, water temperature, and other conditions.
When to replace the tube?
-
The degradation of the laser tube.
-
The failure of the laser tube, which has no laser beam output as well as generates a cracking sound. The Laser tube is classed as consumable, and degradation is expected due to the use of power, storage time, and other factors. The higher the power setting, the faster the laser tube degradation.

Replacement Steps
0. Unplug the power and open the chassis
- Please unplug the power cord first, then replace the laser tube.
- Please use the Torx screwdriver to remove 6 screws on the back cover and lift the cover.
- You can remove the dust from the back chassis first and then replace the laser tube. Use a vacuum cleaner or high-pressure spray gun to remove the dust from the rear chassis, and then use a paper towel or rag with alcohol to wipe the dirty area and wait for the chassis to dry before proceeding with the next operation.
- The laser tube has two ends. The high-voltage ("High-voltage") side is near the screen and the low-voltage ("Low-voltage") side is near the reflective mirror.
- Please put a rag or paper towel on both sides of the high and low voltage to avoid damage to the machine due to water seepage.
1. Disconnect the laser tube wires
Unscrew and disconnect the white connector on the high-voltage side > Press the white terminal and pull out the ground wire on the low-voltage side.
2. Loosen the laser tube holders
Use a 3mm hexagonal wrench to loosen a total of 4 screws on the laser tube holders.
3. Take the laser tube out to drain
a. Use needle nose pliers to move the hose clamp from the low-voltage side toward the center of the water hose
b. Use diagonal pliers to remove the cable tie holding the water hose > Move the laser tube out of the chassis
c. Aim the water hose on the low-voltage side at the water container, and then pull out the hose to drain the water (when the water outlet position of the low-voltage side is lower than that of the high-voltage side, the liquid will be discharged due to siphon principle)
d. When the drainage is completed, clog the water outlet by a water pipe plug.
4. Remove the laser tube
a. To avoid water leakage, place a rag or paper towel under the high-voltage side > Use diagonal pliers to remove the cable tie fixing the water hose >
b. Pull out the water hose on the high voltage-side and insert a water pipe plug >
c. Remove the laser tube completely.
5. Place the laser tube and water hose in
a. Place the laser tube according to the picture >
b. Remove the water pipe plug on the high-voltage side and put the water hose on the glass tube > Remove the water pipe plug on the low-voltage side and put the water hose on the glass tube.
6. Fix the water hose on the laser tube
Fix the water hose at the high-voltage side on the glass tube with a cable tie > Tighten the cable tie and cut off the excess cable tie with a pair of diagonal pliers > Fix the water hose at the low-voltage side on the glass tube with a cable tie > Tighten the cable tie and cut off the excess cable tie with a pair of diagonal pliers > Put the metal hose clamp back.
7. Connect the laser tube wire
Connect the white connector on the high-voltage side with a red wire back and tighten it > Press down the white terminal on the low-voltage side and insert the ground wire firmly > Release the white terminal and gently pull the ground wire to check if it is stable.
8. Tighten the laser tube holders back
a. Place the laser tube in position, leaving a finger distance between the head and tail ends > Rotate the red terminal on the high-voltage side towards the inside of the machine chassis > Make sure there is no folds or kinks of the water hoses
b. Use a 3mm hexagonal wrench to tighten a total of 4 screws on the laser tube holders > Gently shake the laser tube to make sure it will not shift left and right and forwards and backward.
9. Plug in the power cord and start the machine
After confirming the installation is correct, you can plug in the power cord and start the machine.
10. Activate the“Pump”
After the machine is turned on, click “MAINTAIN” on the screen > Click “Pump” after the laser head is homed. Then the cooling water will start to enter the laser tube and the water level of the water pump will drop.
11. Turn off the machine and unplug the power cord
When the water level of the water pump is 1/4 left, turn off the machine and unplug the power cord before adding the water manually.
⚠️
1. Please do not touch the area near the high-voltage side of the laser tube after plugging the power cord in to avoid electric shock.
2. When using the "MAINTENANCE" page, avoid touching the laser switch or putting your hand at the laser tube tail end.
3. Please observe the water level carefully to avoid overflowing.
4. Please use distilled water to avoid impurities affecting the water-cooling effect.
12. Add water manually
Use the double-head wrench to open the water pump cap > Put in the funnel > Fill the water pump with distilled water.
13. Tighten the water pump cap back
Repeat steps 9 ~ 12 until the water pump level reaches 80% full and the water level no longer drops due to the adding into the laser tube, then use the double head wrench to tighten the water pump cap back to complete the laser tube replacement procedure.
⚠️
1. Too many air bubbles inside the laser tube will affect the heat-dissipation efficiency.
2. It is recommended to fill the water to more than 80% full or press the water hose when adding water, so it is less likely to produce air bubbles.
3. If the water pump cannot be activated, please contact your reseller.
4. After moving the laser tube, Optical Path Alignment has to be conducted.
