- Clean: Before first use, wash the pitcher, lid, and tamper with warm, soapy water. Rinse thoroughly and dry. Wipe the motor base with a damp cloth.
- Placement: Place the motor base on a stable, flat, and dry surface. Ensure there is adequate clearance above the blender (approximately 23 inches) for the sound enclosure to open fully without obstruction.
- Assemble: Place the pitcher securely onto the motor base. Ensure it is properly seated. Position the sound enclosure over the pitcher and base, ensuring it is correctly aligned.

Operating Instructions
Basic Blending:
- Add Ingredients: Place your desired ingredients into the pitcher. Do not exceed the MAX fill line (80oz / 2.2L).
- Secure Lid: Place the lid firmly onto the pitcher and ensure the sound enclosure is closed.
- Select Speed: Turn the speed dial to the desired setting (1-15). For initial blending, start with a lower speed and gradually increase as needed.
- Pulse Function: For quick bursts of power or to break down larger chunks, use the Pulse button.
- Add Ingredients During Blending: If necessary, remove the small vented cap from the lid to add ingredients while the blender is operating. Use the tamper through this opening to push ingredients towards the blades if they become stuck.
- Finish Blending: Once desired consistency is achieved, turn the speed dial to 'OFF' and then press the power button to turn off the unit.
