Operating Instructions
1. Preparing Milk for Frothing
For best results, use cold milk. Fill your cup or pitcher with the desired amount of milk. Do not overfill, as milk volume will increase significantly during frothing.
2. Frothing Process
- Submerge the frother head into the milk, ensuring it is fully immersed but not touching the bottom of the container.
- Press the Power Button to start frothing.
- Adjust the speed using the Speed Lever: push up for fast speed (10,000 r/min) or push down for slow speed (8,000 r/min).
- Move the frother gently up and down, keeping the whisk just below the surface to incorporate air, then deeper to create a consistent texture.
- Froth until the milk reaches your desired consistency and volume. This typically takes 15-30 seconds.
- Press the Power Button again to stop the frother.

3. Using the Smart Silicone Ring
The included silicone ring can be used for hands-free frothing or as a stand.
- Hands-Free Frothing: Slide the silicone ring onto the frother body and adjust its height to rest on the rim of your cup or pitcher. This allows the frother to operate independently while you prepare other ingredients.
- Stable Stand: After use, the silicone ring can be positioned to allow the frother to rest horizontally, keeping the whisk head elevated and clean.

Maintenance
1. Cleaning the Whisk Shaft and Head
- Immediately after each use, detach the whisk shaft from the frother body.
- Rinse the whisk shaft and frother head under running water.
- For thorough cleaning, you can briefly operate the whisk in a glass of warm, soapy water.
- Rinse again with clean water and allow to air dry completely before reattaching or storing.
- Caution: The frother body is not waterproof. Do not immerse the main body in water or other liquids.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Frother does not turn on. | Low battery. | Charge the frother using the USB-C cable. |
| Frother head spins weakly or inconsistently. | Low battery; whisk shaft not properly attached; obstruction in whisk. | Ensure frother is fully charged. Reattach the whisk shaft securely. Clean the whisk head to remove any debris. |
| Milk does not froth well. | Milk is too warm; incorrect frothing technique; type of milk. | Use cold milk. Ensure the whisk is submerged correctly and moved gently. Some milk types (e.g., skim milk) froth better than others. |
| Excessive splashing during frothing. | Whisk head too close to the surface; container too full. | Submerge the whisk head deeper into the milk. Do not overfill the container. Use the lower speed setting if necessary. |
