- When finished, slide the speed control back to "0" (OFF) and unplug the mixer.

Using HEATSOFT Technology
The HEATSOFT Technology allows you to soften ingredients like butter or cream cheese while mixing, eliminating the need to wait for them to reach room temperature.
- Follow steps 1-4 for general mixing.
- Press the HEATSOFT button. A gentle warming air will be directed towards the ingredients.
- Begin mixing at a low speed, gradually increasing as the ingredients soften.
- Continue mixing until desired consistency is achieved.
- When finished, release the HEATSOFT button, slide the speed control to "0" (OFF), and unplug the mixer.

Note: The HEATSOFT function is most effective for solid fats like butter and cream cheese. It is not intended for heating liquids.
Using the Boost Function
For an extra burst of power to handle thicker batters or to quickly incorporate ingredients, press and hold the BOOST button during operation. Release the button to return to the selected speed.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Mixer does not turn on. | Not plugged in; power outlet not active; speed control not set. | Ensure mixer is securely plugged into a working outlet. Check that the speed control is set to a number other than "0". |
| Attachments fall out during use. | Attachments not fully inserted; incorrect attachment type for opening. | Ensure attachments are pushed firmly until they click into place. Verify the correct beater/dough hook is in the corresponding opening (larger shaft in larger hole). |
| HEATSOFT function not working. | Button not pressed; nozzle blocked. | Press the HEATSOFT button firmly. Check the magnetic nozzle for any blockages and ensure it is properly attached. |
| Motor sounds strained. | Mixture is too thick; speed setting too low. | Increase speed setting or use the BOOST function for short intervals. If the mixture is excessively thick, consider adding a small amount of liquid or breaking down ingredients further. |
