Warning!

• 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 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 clothes only.

Cleaning Frequency: Daily, after each use*

*What you are engraving will determine the frequency at which you must clean your focal lenses. However, we suggest cleaning your lens after each use for the best results.

Tools Needed:

• Pressurized air
• Hex Wrench
• Cotton swab
• Lens cleaning fluid
• Lens-safe cloth/tissue

Step 1: Move the workbed to about 4 inches (10 cm) beneath the bottom of the lens nozzle.

Step 2: Move the laser head into the center of the work and put a cloth under the lens holder to protect it if it falls loose from the holder.

Step 3: Unscrew the lens holder by rotating to the left.

Step 4: Remove the pressurized air hose and laser guide connections, if there are any.

Step 5: Once positioned over your clean lens-cleaning tissue, remove the lens from the lens holder by carefully turning the lens holder and letting the lens and its O-ring drop onto the cleaning cloth.

Step 6: Examine the lens’s O-ring and—if necessary—clean it with a cotton swab and lens-cleaning fluid.

Step 7: Remove any coarse dust from the lens as well as possible by applying pressurized air.

Step 8: Examine the lens’s surfaces. If it is necessary to clean it, begin by flushing its surfaces with lens-cleaning fluid.

Step 9: Hold the lens assembly by its edge with a lens-cleaning tissue and use a drop of lens-cleaning liquid. While holding the lens at an angle, flush both surfaces to wash away grime.

Step 10: Place the lens on a clean lens-cleaning tissue and apply some lens-cleaning liquid to one side of the lens. Leave the liquid to take effect for approximately one minute, and then gently wipe it away with lens-cleaning tissues soaked in the liquid. Dry this side of the lens with dry lens-cleaning tissues/cloth.

Step 11: Repeat the same cleaning process on the other side of the lens.

NEVER use the same cleaning tissue twice. Dust accumulated during the first use could scratch the other side of the lens during the second.

Step 12: Examine the lens’s surfaces again. Repeat the process above until no dust or haze is present.

Step 13: Carefully insert the lens into the holder, ensuring its rounded convex side faces upwards. Put the O-ring on top of the lens.

Step 14: Carefully reassemble the lens and laser head attachments in reverse order.
