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.

2 | Water container
3 | Paper towel or rag
Included in the accessory box :
4 | Torx screwdriver
5 | Double head wrench
6 | Funnel
Maintenance Steps
0. Unlug the power
- Turn off the machine and unplug the power cord before replacing the cooling water.
- Use a Torx screwdriver to remove the six screws on 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. Take the honeycomb table out
- The mesh part of the honeycomb table is relatively sharp, so please be careful when holding it.
- Move the laser head to the upper right of the working range. If the laser head cannot be moved, go to the “MAINTENANCE” on the screen > “Motors” to release the motors.
- If the machine adopts the autofocus version, please press and hold the side button as shown in the bottom picture, to retract the laser head to prevent hitting the honeycomb table when taking it out.
2. Take the laser head out
Manual focusing : Unscrew the nozzle fastening ring > Take the laser head downward and forward out.
Autofocus : Press and hold the side button, move the laser head down to the bottom and release the button > Use 2.5mm hexagonal wrench to loosen the set screw on the left side of the laser head > Move the laser head down and out.
3. Unscrew the barb fitting and aim the laser head at it
a. Unscrew the barb fitting near the low-voltage side (near the reflective mirror) on the flow sensor >
b. Place the flow sensor inside the water container > Lift up the water hose near the low-voltage side slightly to let some water flow out >
c. Aim the laser head outlet at the barb fitting opening. Be sure to ask someone to assist in holding the flow sensor above the water container to avoid spilling water after the air pump is activated
4. “Air Pump” helps to drain the water
Click the “MAINTAIN” on the screen >Click “Air Pump” to activate the air flow, the cooling water will be drained from the water hose near the high-voltage side > After emptying the water, click “Air Pump” to stop the air flow.
5. Dry and install the laser head
Use paper towels or a rag to dry the laser head >: Put the laser head backward and upward > Tighten the nozzle fastening ring.
Autofocus: Insert the laser head under the Autofocus add-on and push the black air hose to the top > Use a 2.5mm hexagonal wrench to tighten the set screw on the left side of the laser head.
6. Connect the barb fitting back
Pre-turn the water hose by two turns to two and a half turns (the position of the hose clamp can be used as a reference) > Connect the barb fitting back to the flow sensor.
7. Turn off the machine and unplug the power cord
Turn off the machine and unplug the power cord before adding the water manually.
8. Add water manually to 50%
Use a double-head wrench to open the water pump cap > Put in the funnel > Fill the water pump with distilled water.
9. Plug in the power cord and start the machine
Plug in the power cord and start the machine.
10. Activate the“Pump”
After the machine is turned on, click “MAINTAIN” on the screen > After the laser head is homed, click “Pump”, then the cooling water starts to enter the laser tube and the water level of the water pump drops. If the water pump does not work, please contact your reseller.
11. Tighten the water pump cap back
Repeat steps 7 ~ 10 until the water pump level reaches 80% full and the water level no longer drops due to the adding into the laser tube, then you can use a double-head wrench to tighten the water pump cap back to complete the water change.
Please finger-tighten the pump cap in case of any damage to the tank.
⚠️
1. Make sure there is no folds or kinks of the water hoses to affect the water flow.
2. Please use distilled water to avoid impurities affecting the water-cooling effect.
3. Too many air bubbles inside the laser tube will affect the heat-dissipation efficiency. 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.
4. Please observe the water level carefully to avoid overflowing.
5. 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.
6. When using the "MAINTENANCE" page, avoid touching the laser switch or putting your hand at the laser tube tail end.
7. If the water pump cannot be activated, please contact your reseller.
