¶ 2. Cleaning Instructions
¶ Required Tools
- Alcohol
- Non-woven cloth
- Cleaning brush
- 2.0 mm Hex Key
- 2.0 mm Star Key
Always power off the device and unplug the power cable before performing any maintenance. Never disassemble or service the laser module while the device is connected to power.
¶ Step 1: Remove the Housing
Remove the distance sensor from the top. |
Use the Star Key to remove the 4 screws on the front cover, then detach the cover. |
Pull out and remove the bottom air nozzle. |
Use the 2.0 mm Hex Key to remove the 4 screws from the back plate. |
Gently slide the metal housing off the laser module. |
¶ Step 2: Detach the Driver Board
Use the 2.0 mm Hex Key to remove the 4 screws securing the main driver board. |
Use the Star Key to remove the 2 small screws on the sideto release the focus distance sensor. |
¶ Step 3: Remove the Fans
Use the 2.0 mm Hex Key to remove the 4 long hex screws securing the two cooling fans. |
Detach the fans. Collect the 4 silicone spacers located between the fans and the heatsink. |
CAUTION: Do not lose the 4 silicone spacers. They are critical for vibration dampening and maintaining proper fan spacing.
¶ Step 4: Deep Clean
Use the cleaning brush to thoroughly remove dust from the heatsink fins. |
Use the cleaning brush to sweep dust off both fan enclosures. |
Use a cotton swab dipped in alcohol to wipe away stubborn sticky residue from the fan blades. |
Use a non-woven cloth to wipe clean the interior of the metal housing. |
¶ Step 5: Reinstall the Driver Board
Place the driver board back into position and tighten the 4 securing screws using the 2.0 mm Hex Key. |
Re-attach the focus distance sensor to the side and secure it with the 2 Star screws. |
¶ Step 6: Reinstall the Cooling Fans
Insert the 2 long hex screws through the mounting holes of the first fan. |
Slide the silicone spacers onto the protruding ends of the screws at the bottom of the fan. |
Align the screws with the mounting holes on the heatsink and tighten them using the 2.0 mm Hex Key. |
Follow the same procedure to install the second fan. |
¶ Step 7: Final Assembly
Carefully slide the metal housing back onto the module. |
Secure the metal back plate using the 4 hex screws. |
Secure the front cover using the 4 Star screws. |
Reinstall and firmly seat the distance sensor on top. |
Re-attach the air nozzle to the laser emission end. |
WARNING: Ensure the side wires are neatly tucked into the slot. Be extremely careful not to pinch or crush any cables when sliding the metal housing back into place.
Success: The cleaning process is now complete. Your laser module cooling system is ready for use.
¶ Maintenance Recommendations
- Increase the cleaning frequency when processing wood or other dust-heavy materials to prevent overheating.
- Keeping the cooling system clean helps extend the lifespan of the laser module and improves engraving stability.
