Operating Instructions
The KEENSTAR MK701A Milk Frother offers four distinct functions, easily selected by pressing the power button. Ensure the correct whisk is installed for your desired function.
Figure 3: Whisk Selection and Button Press Guide for Frothing and Heating.
General Operation Steps:
- Select Whisk: Choose the appropriate whisk for your desired function. The frothing whisk (with the spring) is for creating foam, while the heating whisk (without the spring) is for warming milk or chocolate without foam. Place the selected whisk securely onto the shaft at the bottom of the frother jug.
- Add Milk: Pour cold milk into the frother jug. Observe the internal MAX/MIN fill lines carefully.
- For frothing (thick or light foam): Do not exceed the lower "MAX" line (115ml / 3.9oz).
- For heating milk/chocolate without frothing: Do not exceed the upper "MAX" line (240ml / 8.12oz).
- Ensure the milk level is always above the "MIN" line (80ml / 2.7oz) for all functions.
- Place Jug: Place the frother jug securely onto the power base.
- Select Function: Press the power button located on the front of the frother repeatedly to cycle through the desired functions. The indicator light will illuminate to confirm the selected mode.
- Start: The frother will automatically begin operation after the function is selected.
- Completion: The frother will automatically stop when the process is complete. Carefully remove the jug from the base and pour your prepared milk.
Specific Functions and Button Presses:
- 1. Thick Warm Foam:
Use the frothing whisk (with spring). Press the power button once. This setting produces rich, dense foam, ideal for cappuccinos.

- 2. Light Warm Foam:
Use the frothing whisk (with spring). Press the power button twice. This setting creates lighter, airier foam, suitable for lattes.
Figure 5: Light Warm Foam preparation.
- 3. Warm Milk/Chocolate:
Use the heating whisk (without the spring). Press the power button three times. This function warms milk or chocolate without creating foam.

- 4. Cold Foam:
Use the frothing whisk (with spring). Press the power button four times. This function creates cold foam, perfect for iced coffees and other cold beverages.

Tips for Best Results:
- For optimal frothing, it is highly recommended to use fresh, cold milk with a fat content greater than 3% (e.g., whole milk). Lower fat milks may produce less dense or stable foam.
- Ensure the frother jug is clean and dry before each use to prevent residue buildup and ensure consistent performance.
- Avoid operating the frother for more than 5 minutes continuously. If multiple cycles are needed, allow the appliance to cool down for a few minutes between uses.

Cleaning and Maintenance
Proper cleaning and maintenance are essential to ensure the longevity and hygienic operation of your KEENSTAR Milk Frother.
- Unplug: Always unplug the appliance from the power outlet and allow it to cool completely before cleaning.
- Clean Jug Interior: The frother jug features a non-stick coating. Remove the whisk. Simply rinse the interior under running water and gently wipe it clean with a soft, non-abrasive sponge or cloth.
- Clean Whisks: Remove both whisks and wash them with warm soapy water. Rinse thoroughly and dry completely before storing or re-using.
- Clean Exterior: Wipe the exterior of the frother jug and the power base with a damp cloth. Do not use abrasive cleaners, metal scourers, or harsh chemicals, as these can damage the finish.
- Important: Never immerse the power base, power cord, or plug in water or any other liquid. The frother jug is also not dishwasher safe.
- Storage: Store the frother in a clean, dry place when not in use. Ensure all parts are dry before storage.

Troubleshooting
If you encounter any issues with your KEENSTAR Milk Frother, please refer to the following table for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Frother does not start or operate. | Appliance not plugged in; power outage; frother jug not correctly placed on the power base. | Ensure the power cord is securely plugged into a working electrical outlet. Check your home's power supply. Re-seat the frother jug firmly onto the power base. |
| Milk does not froth or froths poorly. | Incorrect whisk used; milk level too high or too low; type of milk (low fat content); whisk not properly installed; frother jug interior not clean. | Ensure the frothing whisk (with spring) is used for foam. Check that milk levels are within the MIN/MAX frothing lines. Use fresh, cold whole milk (fat content >3%) for best results. Ensure the whisk is securely attached to the shaft. Clean the frother jug interior and whisk thoroughly. |
| Milk overflows from the jug. | Milk level exceeds the MAX frothing line. | Always ensure that the milk level does not exceed the lower "MAX" line (115ml / 3.9oz) when preparing foam. |
| Milk is not warm enough. | Incorrect function selected; frother stopped prematurely. | Ensure the "Warm Milk" or "Warm Foam" function is correctly selected. Allow the frother to complete its full cycle. |
| Burning smell or milk sticks to the bottom. | Frother jug interior not clean; milk residue left from previous use; milk level below MIN line. | Clean the frother jug thoroughly after each use to prevent residue buildup. Always ensure milk is above the MIN line before starting. The auto shut-off feature is designed to prevent dry burning, but proper usage is key. |
