3. Setup and Usage Instructions
Proper setup and use are crucial for safety and optimal performance. Always ensure components are securely connected before applying force.
3.1. Extension Bars (BE3-050, BE3-075, BE3-150)
Extension bars are used to extend the reach of your socket wrench, allowing access to fasteners in deep or obstructed areas.
- Connection: Insert the square drive end of the extension bar completely into the socket or ratchet. Ensure a firm connection.
- Warning: Do not connect and use more than two extension bars simultaneously. Using more than two can lead to excessive leverage, potential bending, or breakage of the tools.
3.2. Universal Joint (BJ3)
The universal joint provides flexibility, allowing you to turn fasteners at an angle when direct access is not possible.
- Connection: Connect the universal joint between your ratchet/extension bar and the socket. Ensure the square drives are fully inserted into the base of the joint.
- Operation: The joint allows for approximately 90 degrees of angular movement.
- Warning: The joint part is vulnerable to impact and twisting. Be careful not to apply excessive force, especially when working at extreme angles, as this can cause damage to the joint.

3.3. Quick Spinner (BE3-Q)
The quick spinner is a dedicated tool for rapid turning of fasteners under light load, significantly speeding up assembly and disassembly tasks.
- Connection: Use the quick spinner in combination with a ratchet handle or extension bar for enhanced effectiveness. Connect the square drive fully.
- Grip Design: The grip features a tactile shape and grooves that indicate a 90° rotation angle, making it easy to understand the rotation. The surface also has angle markings every 30°. The grip is lightweight and made of resin.
- Warning: Do not connect and use more than two quick spinners or extension bars in series with the quick spinner.

4. General Operation Guidelines
- Always select the correct size socket for the fastener to prevent rounding or damage.
- Ensure all connections between tools (ratchet, extension, joint, socket) are secure before applying torque.
- Avoid using excessive force that could damage the tool or fastener.
- Wear appropriate personal protective equipment, such as safety glasses, when using hand tools.
- Keep tools clean and free from grease or oil to maintain a secure grip.
5. Maintenance
Regular maintenance will prolong the life of your KTC tools:
- Cleaning: After each use, wipe down tools with a clean cloth to remove dirt, grease, and debris.
- Lubrication: Periodically apply a light coat of machine oil to moving parts, such as the universal joint, to ensure smooth operation and prevent corrosion.
- Storage: Store tools in a dry environment to prevent rust. Keep them organized in a toolbox or tray to prevent damage and loss.
- Inspection: Before each use, inspect tools for any signs of wear, cracks, or damage. Do not use damaged tools; replace them if necessary.
6. Troubleshooting
Most issues with hand tools can be resolved by following proper usage guidelines:
- Tool Slipping: Ensure the socket is correctly seated on the fastener and that the square drive connections are fully engaged. Avoid using worn-out sockets or fasteners.
- Difficulty Turning: If a fastener is stuck, apply penetrating oil and allow it to soak. Ensure you are using the correct tool for the required torque. Do not over-extend tools beyond their intended use.
- Damage to Tools: Damage often occurs from using tools improperly, such as applying excessive force, using them as pry bars, or connecting too many extensions. Always use tools for their intended purpose.
