3.1 Kutsegula ndi Kuyika
Carefully remove the laser engraver from its packaging. Place the machine on a stable, level surface in a well-ventilated area. Ensure sufficient space around the machine for air circulation and access.
3.2 Njira Yoziziritsira Madzi
The K40+ features a built-in water cooling tube. Connect the external water pump (if supplied) to the designated inlet and outlet ports on the machine. Fill the water reservoir with distilled water. Ensure water flows correctly through the system before powering on the laser. Incorrect hose connection can prevent operation.
3.3 Dongosolo Lothandizira Mpweya
The integrated 45° air assist system automatically adjusts airflow based on laser power. This system helps clear smoke and debris from the cutting area, protects the lens, reduces wood carbonization, and minimizes fire risk. Ensure the air assist nozzle is clear of obstructions.

5.2 Lens and Mirror Cleaning
Periodically inspect and clean the laser lens and mirrors using appropriate optical cleaning solutions and lint-free wipes. Contaminants can degrade laser performance and lifespan.
5.3 Water Cooling System Maintenance
Regularly check the water level and quality in the cooling system. Replace distilled water as needed to ensure optimal cooling for the laser tube and extend its lifespan. Consider using a laser coolant additive for enhanced performance and algae prevention.
6. Mavuto
This section addresses common issues encountered during operation.
- Laser Sikuwombera:
- Check if the lid is fully closed and the safety interlock is engaged.
