1. Product Overview
The KTC NBE28 Quick Spinner is a specialized tool designed to enhance the efficiency of socket wrench operations. It attaches between a ratchet handle and a socket, facilitating rapid turning of the socket for quicker and more comfortable work. This tool is part of the Nepros series, known for its focus on lightweight, strong, and aesthetically refined tools. It is suitable for both tightening and loosening applications.

2. Setup and Installation
The NBE28 Quick Spinner is designed for easy integration into your existing 0.25 inch (6.3 mm) drive socket wrench system.
- Select Appropriate Tools: Ensure you have a 0.25 inch (6.3 mm) drive ratchet handle and the desired socket.
- Attach to Ratchet: Insert the square drive end of the Quick Spinner into the drive head of your ratchet handle. Ensure it clicks securely into place.
- Attach Socket: Connect the desired socket to the other square drive end of the Quick Spinner. Verify that the socket is firmly attached.
Once assembled, the Quick Spinner will be positioned between the ratchet and the socket, ready for use.

3. Operating Instructions
The KTC NBE28 Quick Spinner is designed to facilitate rapid rotation of fasteners once they are initially broken loose or before final tightening. It eliminates the need for continuous ratcheting when there is no resistance.
- Initial Loosening/Final Tightening: Use your ratchet handle to apply the necessary torque for initial loosening or final tightening of the fastener.
- Quick Spinning: Once the fastener is loose enough to turn by hand, or before it requires significant torque for tightening, use the knurled outer ring of the Quick Spinner to rapidly rotate the socket. This allows for quick engagement or disengagement of threads without operating the ratchet mechanism.
- Direction: The Quick Spinner can be used for both clockwise (tightening) and counter-clockwise (loosening) rotation.
This functionality significantly speeds up tasks involving fasteners that require many turns, such as long bolts or nuts.
4. Maintenance
Proper maintenance ensures the longevity and optimal performance of your KTC NBE28 Quick Spinner.
- Cleaning: After each use, wipe the tool clean with a dry cloth to remove any dirt, grease, or debris. For stubborn grime, a mild solvent or degreaser can be used, followed by thorough drying.
- Lubrication: Periodically apply a light coat of machine oil to the moving parts and square drive ends to prevent corrosion and ensure smooth operation. Avoid excessive lubrication.
- Storage: Store the Quick Spinner in a clean, dry environment, away from excessive moisture or corrosive chemicals.
- Inspection: Regularly inspect the tool for any signs of wear, damage, or deformation. Discontinue use if any significant damage is observed.
5. Troubleshooting
If you encounter issues with your KTC NBE28 Quick Spinner, consider the following:
- Difficulty Attaching/Detaching: Ensure that both the ratchet and the socket are clean and free of debris. Apply a small amount of lubricant to the square drive ends if they are stiff.
- Reduced Spinning Smoothness: This may indicate a need for cleaning and lubrication. Follow the maintenance guidelines in Section 4.
- Wobble or Loose Fit: While some tools may have slight manufacturing tolerances, excessive wobble could indicate wear on the drive ends of the Quick Spinner, ratchet, or socket. Inspect all components for damage.
If problems persist or if you suspect a defect, please contact KTC customer support for assistance.
