Setup
The KTC Quick Spinner BE4-Q is an accessory designed to enhance the functionality of your existing ratchet or extension bar. Follow these steps to set up the tool:
- Inspect the Tool: Before each use, visually inspect the Quick Spinner for any signs of damage, wear, or deformation. Ensure the drive square is clean and free of debris.
- Attach to Drive Tool: Insert the 12.7mm (0.5 inch) square drive end of the Quick Spinner into the corresponding drive opening of your ratchet or extension bar. Ensure it is fully seated and securely engaged.
- Attach Socket: Connect the desired socket to the square drive of the Quick Spinner. Verify that the socket is firmly attached.

Operating Instructions
The Quick Spinner is designed for efficient, rapid turning of fasteners in situations where minimal torque is required. It is not intended for applying high torque to loosen or tighten stubborn fasteners.
- Application: Use the Quick Spinner for fast rotation of nuts and bolts once they have been initially loosened or before they are fully tightened. It is ideal for quickly running fasteners in or out.
- Light Load Only: This tool is specifically for use under light load conditions. Applying excessive force or using it to break loose seized fasteners can damage the tool or the fastener.
- Angle Display: The red resin grip features an angle display. This allows you to visually monitor the rotation angle, which can be useful for tasks requiring precise turning increments.
- Rotation: Hold the red grip and rotate it with your fingers to quickly turn the attached socket and fastener.

Safety Precaution: Always ensure the fastener is not excessively tight before using the Quick Spinner. For initial loosening or final tightening, use a standard ratchet or wrench.
Maintenance
Proper maintenance ensures the longevity and reliable performance of your KTC Quick Spinner.
- Cleaning: After each use, wipe the tool clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, a mild solvent can be used, ensuring it does not damage the resin grip.
- Storage: Store the Quick Spinner in a clean, dry environment, away from excessive moisture or corrosive substances.
- Inspection: Periodically inspect the square drive and the resin grip for any signs of wear, cracks, or damage. Replace the tool if significant wear or damage is observed to prevent injury or damage to fasteners.
Troubleshooting
If you encounter issues with your KTC Quick Spinner, consider the following:
- Difficulty Turning: If the Quick Spinner is difficult to turn, ensure the fastener is not overtightened or seized. This tool is for light loads only. Do not force it.
- Loose Connection: If the Quick Spinner feels loose when attached to a ratchet or extension bar, ensure it is fully seated and the drive square is not worn.
- Damage: If the tool appears damaged (e.g., cracked grip, bent drive), discontinue use immediately to prevent injury or further damage.
