Setup and Assembly
Before first use, ensure all packaging materials are removed and clean all removable parts as described in the 'Maintenance and Cleaning' section.
Assembly Steps:
- Prepare Ingredients: Add your desired ingredients into one of the 27oz blending cups. Do not exceed the 'MAX' fill line.
- Attach Blade Assembly: Screw the appropriate blade assembly (6-leaf for wet blending, 2-leaf for dry grinding) onto the open end of the blending cup. Turn clockwise until securely tightened.
- Place on Power Base: Invert the assembled cup and blade, then place it onto the power base. Align the tabs on the cup with the slots on the base.
- Secure the Cup: Twist the cup clockwise until it locks into place. The blender will not operate unless the cup is properly secured.

Operating Instructions
The KOIOS BL219B blender offers three blending options for various food types.
Blending Process:
- Ensure the blender is properly assembled and plugged into a power outlet.
- Twist the blending cup clockwise to lock it onto the power base. The blender will activate once locked.
- The blender features a Safety Lock mechanism, preventing operation if the cup is not correctly engaged.
- Select the desired blending mode by twisting the knob on the base. The 900W motor with 25000 RPM high speed can process ingredients quickly.
- Blend until desired consistency is achieved. For optimal results, blend in short pulses rather than continuous operation, especially for tougher ingredients or ice.
- Once blending is complete, twist the cup counter-clockwise to unlock and remove it from the power base.
- Unscrew the blade assembly from the cup and attach a to-go lid if you plan to take your drink with you.
Tips for Best Results:
- For smoothies, always add liquids first, then soft ingredients, and finally frozen items or ice.
- Do not overfill the blending cup. Leave some space for ingredients to circulate.
- If ingredients are not blending, remove the cup, shake it gently, and re-attach to continue blending.
- The 6-leaf stainless steel blade is designed to crush ice and frozen ingredients effectively.

Maintenance and Cleaning
Proper cleaning ensures the longevity and hygiene of your KOIOS blender.
Cleaning Steps:
- Unplug: Always unplug the power base before cleaning.
- Blade Assembly: Carefully unscrew the blade assembly from the blending cup. Rinse the blades under running water immediately after use to prevent food residue from drying. Use the included cleaning brush for hard-to-reach areas.
- Blending Cups and Lids: The blending cups and to-go lids are dishwasher safe. Alternatively, wash them with warm, soapy water and rinse thoroughly.
- Self-Cleaning Function: For quick cleaning, add warm water and a drop of dish soap to the blending cup, secure the blade assembly, and place it on the power base. Run the blender for 30 seconds. Rinse the cup and blade assembly afterward.
- Power Base: Wipe the power base with a damp cloth. Do not immerse the power base in water or any other liquid.

Troubleshooting
If you encounter issues with your blender, refer to the following common problems and solutions:
- Blender Does Not Start:
- Ensure the power cord is securely plugged into a working electrical outlet.
- Verify that the blending cup is properly assembled with the blade and securely locked onto the power base. The safety lock prevents operation if not correctly engaged.
- Ingredients Not Blending Smoothly:
- Add more liquid to the blending cup.
- Do not overfill the cup beyond the 'MAX' line.
- Remove the cup from the base, shake it gently to redistribute ingredients, and re-attach to continue blending.
- Ensure frozen ingredients or ice are broken into smaller pieces if necessary.
- Motor Stops During Operation (Overheat/Overload):
- The blender is equipped with overheat and overload protection. If the motor stops, unplug the unit immediately.
- Remove the blending cup and allow the motor base to cool down for at least 15-20 minutes before attempting to use it again.
- Reduce the amount of ingredients or add more liquid for easier blending.
- Leakage from the Blending Cup:
- Ensure the blade assembly is tightly screwed onto the blending cup.
- Check if the gasket within the blade assembly is properly seated and not damaged.
- Do not overfill the cup.
