Maintenance

It is recommended that you perform the following two key steps at least once a month.

1. Turn on and dry the device for 30 minutes.

Turn on your F2 Ultra UV and keep it running for at least half an hour. This operation allows the device to generate heat while running, automatically drying internal moisture and effectively protecting the UV laser core components that are sensitive to humidity.

2. Check the surfaces of the field lens and the galvanometer mirrors.

Ensure that the surfaces of the field lens and the galvanometer mirrors are clean and free of debris. Dust or dirt on these components can significantly reduce processing quality and may cause degradation or damage.

Why are the above operations important?

• Prevent irreversible damage: Your F2 Ultra UV is equipped with a precise ultraviolet laser. If the device remains unused for an extended period—for example, over six months—especially in humid environments, the aging of its critical components, such as the frequency-doubling crystal, could accelerate, potentially leading to irreversible performance degradation.
• Maintain consistent results: Keeping the field lens and galvanometer mirrors clean is fundamental to achieving optimal processing results.

Other maintenance tips:

• Use the device in a temperature-controlled environment (10–30°C or 50–86°F).
• Use the device in a dry and well-ventilated area. Avoid using it in humid environments.
• If the device will not be used for an extended period, store it in a dry environment.

Cleaning

1. Clean the field lens

When laser power attenuation occurs, for example, engraved patterns are shallow or materials can't be cut as expected, the field lens may get dirty. Clean it with the lint-free cloth moistened with absolute ethanol.

2. Clean the galvanometer mirrors

After removing the field lens from the device, never touch the two galvanometer mirrors located above it with your hands. Use a lint-free cloth moistened with absolute ethanol to gently clean them only if they appear dirty.

3. Clean the fan module

When smoke runs out of the protective enclosure, the fan module may be blocked by dust. Clean it to ensure proper smoke exhausting.

(1) Remove the magnetic fan guard from the smoke outlet.

(2) Open the cover, and then take out the fan module.

(3) Open the cover to access the fan.

(4) Use a brush or other tools to clean the fan module and the magnetic fan guard. Then, install them back to the main unit.

Dos and don'ts

Surface engraving lens and inner engraving lens replacement

Please follow the guidelines below for this precision operation.

1. NEVER touch the galvanometer mirrors with your hands! After removing the field lens, under no circumstances should you touch the two galvanometer mirrors inside the device with your hands.

2. The field lens and galvanometer mirrors must be kept absolutely clean.

3. To clean the field lens (surface engraving lens or inner engraving lens), use a lint-free cloth moistened with absolute ethanol.

4. To clean the galvanometer mirrors, use a lint-free cloth moistened with absolute ethanol to gently wipe them only if you confirm the presence of dirt or contamination.

Slatted panel

The slatted panel serves to provide support, guide airflow, and protect the device’s baseplate during use. When engraving thin or transparent materials, use the slatted panel to avoid damaging the device’s baseplate.

Riser for inner engraving

The riser for inner engraving serves as a support and positioning tool during use. During the inner engraving process of a glass workpiece, if the engraved model is low and the focal point is close to the riser top plate, there is a risk of damage to the riser top plate. Please use it with caution.

Emergency stop button

The emergency stop button is used to cut off the device's power supply in emergency situations. Do not use the emergency stop button as the device's power button.
