4. Operating Instructions
Once the blade assembly and cup are securely attached to the blender base, you can begin blending.
- Plug In: Plug the blender power base into a suitable electrical outlet.
- Start Blending: Press down on the cup to activate the blending action. For continuous blending, twist the cup further clockwise until it locks into the "ON" position (if your blender model supports this).
- Blending Duration: Blend in short bursts (pulse) or continuously for up to 1 minute per cycle.
- Avoid Overheating: If more blending is required after 1 minute, release the cup, wait 1 minute, and then repeat the blending cycle. After three consecutive 1-minute blending cycles, allow the blender power base to cool for 3-5 minutes to prevent overheating.
- Finish Blending: Once desired consistency is achieved, release pressure on the cup or twist it counter-clockwise to the "OFF" position.
- Remove Cup: Unplug the blender. Twist the cup counter-clockwise to unlock it from the power base, then lift it off.
- Remove Blade Assembly: Carefully twist the blade assembly counter-clockwise to remove it from the cup.
Important: Always ensure the blender is unplugged before removing or attaching any parts.
5. Cleaning and Maintenance
Proper cleaning and maintenance will extend the life of your Sduck Replacement Blade Assembly.
- Immediate Cleaning: Clean the blade assembly immediately after each use to prevent food from drying onto the blades and seals.
- Hand Washing: Wash the blade assembly with warm, soapy water. Use a brush to clean around the blades carefully. Rinse thoroughly.
- Dishwasher Safe: The blade assembly is generally top-rack dishwasher safe. However, hand washing is recommended for longevity, especially for the rubber gasket.
- Drying: Allow all parts to air dry completely before storing or reassembling.
- Gasket Inspection: Periodically inspect the rubber gasket for any signs of wear, cracks, or damage. A damaged gasket can lead to leaks.
- Storage: Store the blade assembly in a dry place, away from direct sunlight.
6. Troubleshooting
| Problem | Possible Cause | Solution |
