4. Setup and Assembly
Follow these steps to assemble your Uten Smoothie Blender:
- Prepare Ingredients: Wash and cut your fruits, vegetables, or other ingredients into small pieces.
- Fill the Cup: Place your ingredients into the blending cup. Do not overfill; ensure ingredients are below the MAX fill line. For best results, add liquids first, then soft ingredients, and finally harder ingredients or ice.
- Attach Blade Assembly: Screw the appropriate blade assembly (blending or grinding) onto the open end of the cup until it is securely tightened.
- Place on Motor Base: Invert the cup and blade assembly, then place it onto the motor base. Align the tabs on the cup with the slots on the base and twist clockwise until it locks into place. The blender will not operate if not correctly locked.
- Connect Power: Plug the power cord into a suitable electrical outlet.

5. Operation
The Uten Smoothie Blender features a control dial for different speeds and functions.
5.1 Speed Settings
- 'P' (Pulse): For short bursts of power, ideal for chopping or breaking down tougher ingredients. Turn the dial to 'P' and release.
- '0' (Off): The blender is off.
- '1' (Low Speed): Continuous low-speed blending for softer ingredients or gentle mixing.
- '2' (High Speed): Continuous high-speed blending for smoothies, crushing ice, or processing harder ingredients. The motor can reach up to 22,000 RPM.
5.2 Blending Process
- After assembly, select your desired speed setting ('1' or '2') or use the 'P' (Pulse) function.
- Blend until the desired consistency is achieved. For optimal results, blend in short intervals rather than continuously for extended periods.
- If ingredients are stuck, turn off the blender, unplug it, remove the cup, shake it, and re-attach before continuing. Do not use utensils to dislodge ingredients while the blender is running.
- Once blending is complete, turn the dial to '0' (Off) and unplug the appliance.
- Carefully remove the cup from the motor base by twisting counter-clockwise.
- Unscrew the blade assembly and replace it with the travel lid if you plan to take your drink on the go.

- Manual Cleaning: Wash the blending cup, blade assembly, and lids with warm, soapy water. Use a brush to clean around the blades carefully. Rinse all parts thoroughly and allow them to air dry completely before storing.
