Product Overview

This image displays the Robot Coupe 27138 S-Blade, featuring its distinctive coarse serrations designed for specific food processing tasks. The blade is constructed from durable metal, with a central hub for attachment to the food processor's motor shaft and two curved blades with serrated edges.
Installation Instructions
Follow these steps to safely install the Robot Coupe 27138 S-Blade into your compatible food processor.
- Ensure Power Off: Before beginning, ensure your Robot Coupe food processor is unplugged from the electrical outlet.
- Remove Bowl: Carefully remove the food processor bowl from the motor base, if it is already attached.
- Handle Blade Safely: Grasp the 27138 S-Blade firmly by its central plastic or metal hub. Do not touch the serrated cutting edges.
- Position Blade: Place the S-Blade onto the central shaft within the food processor bowl. Ensure the blade drops completely down and is securely seated on the shaft. It should not wobble or feel loose.
- Attach Bowl and Lid: Once the blade is securely in place, attach the food processor bowl to the motor base and then secure the lid according to your food processor's specific instructions.
- Verify Security: Before plugging in the appliance, gently try to lift the blade by its hub to confirm it is firmly attached to the shaft.
Refer to your specific Robot Coupe food processor manual for detailed instructions on bowl and lid assembly.
Operating Instructions
The Robot Coupe 27138 S-Blade with Coarse Serrations is designed for specific processing tasks. Always operate your food processor according to its primary instruction manual.
- Food Preparation: Cut larger food items into pieces that fit comfortably within the food processor bowl without exceeding the maximum fill line.
- Processing: With the blade, bowl, and lid securely in place, plug in the food processor. Use the appropriate speed settings for your desired consistency. The coarse serrations are ideal for tasks requiring a less fine chop or for processing tougher ingredients.
- Monitoring: Observe the food processing through the lid. Process in short pulses for better control over consistency.
- Stopping: Once processing is complete, turn off the food processor and unplug it from the power outlet before removing the lid or bowl.
- Removing Food: Carefully remove the blade by its central hub before emptying the processed food from the bowl.
Note: The coarse serrations are particularly effective for tasks like kneading dough, mixing batters, or coarsely chopping ingredients where a finer puree is not desired. Avoid using this blade for tasks that require a perfectly smooth consistency, as the coarse edges will leave a more textured result.
Care and Maintenance
Proper care and maintenance will extend the life of your Robot Coupe 27138 S-Blade.
- Cleaning: Always unplug the food processor before cleaning. Carefully remove the blade. Wash the blade immediately after use to prevent food from drying on it. Hand washing with warm, soapy water is recommended. Use a brush to clean around the serrations carefully. Rinse thoroughly and dry immediately to prevent water spots or corrosion.
- Dishwasher Use: While some components may be dishwasher safe, hand washing is generally preferred for blades to maintain sharpness and finish. Consult your food processor's main manual for specific dishwasher compatibility.
- Storage: Store the blade in a safe place where its sharp edges cannot cause injury and where it is protected from damage. Consider using a blade cover if available.
- Inspection: Periodically inspect the blade for any signs of wear, damage, or dullness. A damaged or excessively dull blade should be replaced to ensure optimal performance and safety.
Troubleshooting
If you encounter issues with your Robot Coupe 27138 S-Blade, consider the following:
| Problem | Possible Cause | Solution |
|---|---|---|
| Blade not processing food effectively. | Blade is dull or damaged. Incorrect food quantity. | Inspect blade for damage; replace if necessary. Adjust food quantity to recommended levels. |
| Blade wobbles or makes unusual noise. | Blade not properly seated on the motor shaft. | Unplug the appliance, remove the blade, and re-install ensuring it is securely seated. |
| Food processor not starting with blade installed. | Lid or bowl not properly locked. | Ensure the bowl and lid are correctly assembled and locked into place, activating the safety interlock. |
