Setup
- Unpack Components: Carefully remove all parts from the packaging. Retain packaging for future storage or transport.
- Wash Parts: Before first use, wash all blending vessels, lids, and the blade assembly in warm, soapy water. Rinse thoroughly and dry. The blender base should only be wiped clean with a damp cloth.
- Position Blender: Place the blender base on a clean, dry, and stable surface. Ensure the power cord is not obstructed.
Operating Instructions
Follow these steps for safe and effective blending:
- Add Ingredients: Fill your chosen blending vessel with ingredients. For best results, add liquids first, followed by soft ingredients, then harder ingredients and ice. Do not overfill past the MAX fill line.
- Attach Blade Assembly: Screw the stainless steel blade assembly firmly onto the open end of the blending vessel until it is tightly sealed.
- Place on Base: Invert the vessel and blade assembly, then place it onto the blender base. Align the tabs on the vessel with the slots on the base and twist clockwise until it locks into place.
- Start Blending: Press the power button on the front of the blender base. The Mighty 850 features an automatic 1-minute blend cycle. You can also pulse by pressing and holding the button for shorter bursts.
- Remove Vessel: Once blending is complete, twist the vessel counter-clockwise to unlock it from the base, then lift it off.
- Serve or Store: Unscrew the blade assembly. You can then attach a drinking lid, carry cap, or storage lid to the vessel for immediate consumption or storage.
