The lens has a durable coating and won’t be damaged by correct and careful cleaning. If not clean, your laser will be less efficient and heat buildup on the oil or dust itself can damage the lens.

Cleaning Frequency: Daily, 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 the following steps not to touch the lens surface directly with your hands or with any dirty, oily, or abrasive surface. Use lens-safe gloves or cloths only.

Detaching the Focus Lens

1. Move the engraving table to a distance of approximately 4 inches (10 cm) under the lens holder.

   

2. Move the laser head into the center of the workbed and put a cloth under the lens holder so that the lens will not be damaged if it accidentally falls from its holder.

   

3. Remove the pressurized air hose by pulling it out.

   

4. Remove the laser guide connection by rotating it toward you and loosen it. The lens holder should be detached.

   

5. Remove the nozzle by rotating it toward you.

   

6. Remove the lens from the lens holder by turning the lens holder lock ring counterclockwise with the focus lens repair tool and letting the lens and its O-ring drop onto the cleaning cloth.

   When using the focus lens repair tool, ALWAYS use the end that matches the lens size to prevent scratching the surface.

   

    

Cleaning the Focus Lens and Its O-Ring

1. Examine the lens surface, remove coarse dust as well as possible by blowing air onto the lens surface and, if necessary, clean it with the lens cleaning liquid and lens tissue or cloth as below.

   a. Put the lens on a clean lens-cleaning tissue.

   b. Put some lens-cleaning liquid on one side of the lens.

   c. Leave the liquid to take effect for approximately one minute.

   d. Gently wipe the liquid away with lens-cleaning tissues soaked with lens-cleaning liquid.

   e. Dry this side of the lens with dry lens-cleaning tissues/cloth.

2. Repeat the same cleaning process on the other side of the lens.

   Note:  NEVER use a cleaning tissue twice. Dust accumulated in the cleaning tissue could scratch the lens surface.

3. Examine the O-ring and, if necessary, clean it with a cotton bud and a lens-cleaning tissue or cloth.

4. Examine the O-ring and lens to ensure they are clean. If any dirt remains, repeat the cleaning process until both are thoroughly clean.

   Note:  Do not touch the surface of the lens after cleaning.

Reattaching the Focus Lens

1. Carefully insert the lens into the lens holder, ensuring that its rounded convex side is facing upwards.

2. Put the O-ring on top of the lens.

3. Carefully reassemble the lens lock ring, the laser guide connection, and the pressurized air hose in reverse order.
