Cleaning The Water System; Cleaning The Focus Lens - Omtech SH-G570 User Manual

6.2.2 Cleaning the Water System

NEVER touch or adjust your engraver's water supply while the pump is still
connected to power.
Because distilled water can leach chemicals from your tank and/or hoses and spread these possibly
corrosive particles to the laser tube, change your water each week regardless of its level or clarity to
maximize your laser's service life.
While changing the water, clean the tank and pump completely to minimize any buildup of residue or
chemicals.
1. Turn off the laser engraver and unplug the pump.
2. Open the water tank, remove the pump, and clean both.
3. Disconnect the pump's hose, allowing it to drain, and clean it if needed.
4. Reconnect the hose and replace the pump inside the tank.
5. Add your new water to the tank.
6. Plug the pump in again and allow it to run for 2–3 minutes to restore the water throughout the
engraver's cooling system.
Before starting the laser, visually confirm water is running through the laser tube without bubbles and
check the water temperature.

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 focus lens repair 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.
