# System Maintenance

## Reduce Fire Risk with a Clean Laser

* Cleaning the Fusion Pro is an excellent way to prevent fire with the laser.
* A buildup of cutting and engraving residue and debris is dangerous and can create a fire hazard in its own right.
* Keep your laser system clean and free of debris.&#x20;
* Regularly remove the Vector Cutting Table to clean any small pieces that have fallen through the grid.





## Cleaning the Optics

* Clean your laser optics periodically or if you notice dust buildup.&#x20;
* Accumulated contaminants like smoke or resin can reduce laser power and damage the lens.

{% hint style="success" %}
**When cleaning the optics, jogging the laser closer to the front of the machine will allow for easier access.**
{% endhint %}





### Cleaning the Lens

* The focus lens is contained within the lens tube.&#x20;
* The lens tube is a single assembly and is fairly easy to clean.
* Remove the lens tube from the machine for cleaning by unscrewing the captive screw on the front lens clamp using a screwdriver.&#x20;
* Hold the lens tube from the bottom while unscrewing the captive screw, as the tube may come out easily.

* Remove the captive screw, then the lens tube. Twist off the bottom cone piece to reveal the lens.

* To clean the lens, use a high-quality cotton swab moistened with the optics cleaner supplied in the accessory kit. Please read the label on the bottle carefully.

* Allow the optics to dry, then twist the cone piece securely back on to the bottom of the lens tube.

* Align the hole near the bottom of the lens tube with the air assist hole.&#x20;
* Ensure the top notch of the tube matches the insert on the assembly.
* &#x20;The tube should slightly shift when twisted. Wrap the clamp around the tube and tighten the screw.

### Cleaning the Mirror

* The mirror is located on the back side of the assembly and also has a simple cleaning process.&#x20;
* Start by opening the door latched onto the back of the assembly. The door will rotate counterclockwise to open.

*   Next, twist the knob on the right side of the assembly counterclockwise to loosen the mirror, preparing it

    for removal

## Replacing the Lens

* Replace the old lens with a new one by removing the lens tube from the machine.&#x20;
* Unscrew the captive screw on the front lens clamp using a screwdriver while holding the tube from the bottom.
* Insert the new lens tube and secure it properly.

* Insert the new tube into the assembly, aligning the hole at the bottom with the air assist hole, and the notch at the top with the insert.&#x20;
* The tube should only shift slightly when twisted. Wrap the clamp around the tube and tighten the screw.

## Cleaning the Exhaust Plenum

* Keep your exhaust blower in good shape. Clean the duct system often to get rid of debris.
* If you notice odors or smoke near the lens carriage, check the exhaust system for loose connections or blockages.
* Occasionally check the blower and duct work as shown in the following photos.



### Cleaning the Vents

Clean the vents inside the machine with a flexible or wire brush.
