Warning!

• Disconnect the engraver from power before cleaning.
• Completely wipe the surfaces dry after cleaning.
• NEVER allow the electronic elements to become wet.
• Be careful not to directly touch the lens surface with your hands or any dirty, oily, or abrasive surface. Use lens-safe gloves or cloth 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 to a convenient location and put soft material underneath so the lens will be protected if it falls loose during removal or replacement.

Step 3: Remove the air assist hose from the laser nozzle.

Step 4: Loosen the bolt in the upper part of the laser head that holds the middle part in place.

Step 5: Carefully slide the middle part of the laser head out and remove the lens from its casing.

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: Set it on a lens-safe cloth, apply more cleaning fluid, and allow about one minute for it to take effect. Gently wipe it clean with a lens tissue wetted with the cleaning fluid. Repeat the process on the other side of the lens.

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

Step 10: Examine the lens’s surfaces again. Repeat the process above until no dust or haze is present.

Step 11: Return the lens and its O-ring to their housing, being careful that the lens’s rounded convex side is facing upward away from the workbed.

Step 12: Carefully reassemble the laser head in reverse order and then restore the nozzle connections.
