6.2.2 Cleaning the Water System
See your water cooling system's manual for reference to ensure that the water used remains cool,
clean, and pure.
6.2.3 Cleaning the Focus Lens
The lens has a durable coating and won't be damaged by correct and careful cleaning. You should
check the lens and the 3rd mirror daily and clean them if there is any debris or haze on their surface. If
not clean, your laser will be less efficient and heat buildup on the oil or dust itself can damage the lens.
Cleaning Frequency: After each use
Tools Needed:
• Lens-cleaning liquid
• Lens tissue or cloth
• The lens removal tool
• Disconnect the engraver from power before cleaning.
• Completely wipe dry the surfaces after cleaning.
• NEVER allow water to come into contact with the electronic elements.
• Be careful in all of the following steps not to directly touch the lens surface
with your hands or any dirty, oily, or abrasive surface. Use lens-safe gloves or
cloths only.
