Operating Instructions
The Mueller Immersion Blender is designed for ease of use. Follow these steps for optimal performance:
General Operation
- Ensure the blender is properly assembled with the desired attachment.
- Plug the power cord into a standard 120V AC outlet.
- Submerge the blade or attachment into the ingredients. For best results, ensure the blending head is fully immersed to prevent splashing.
- Press and hold the power button to start blending.
- Release the power button to stop.
Speed Control and Turbo Mode
The blender features a variable 8-speed control dial and a separate Turbo button for maximum power.
- Variable Speed Dial: Rotate the dial on top of the motor unit to select speeds from 1 to 8. Lower speeds (1-3) are ideal for softer ingredients like bananas or strawberries. Medium speeds (4-6) are suitable for items like garlic or peaches. Higher speeds (7-8) are for tougher ingredients such as nuts or raw meat.
- Turbo Mode: For an extra burst of power, press and hold the 'TURBO' button. This will activate the maximum blending speed regardless of the dial setting. Release the button to return to the selected dial speed.

The ergonomic handle features an intuitive 8-speed control dial and a dedicated Turbo button for enhanced blending power.
Using Attachments
- Blending Shaft: Ideal for pureeing soups directly in the pot, blending smoothies in a tall glass, or making baby food. The stainless steel blade housing helps reduce splashes.
- Whisk Attachment: Perfect for whipping cream, beating eggs, or mixing batters for pancakes and cakes.
- Milk Frother Attachment: Creates rich, creamy foam for lattes, cappuccinos, and other beverages.

The Mueller Immersion Blender is versatile for preparing a wide range of dishes, from smooth soups to whipped cream.

The contoured shape of the handle provides a secure and comfortable grip during use.
