5. 사용 설명서

1. 패스너 준비: Ensure the fastener and its threads are clean and free of debris. Apply thread compound or grease if recommended by the component manufacturer.
2. Select Torque and Bit: As described in Section 4, select the appropriate bit and set the wrench to the required torque value (4, 5, or 6 Nm).
3. Engage the Fastener: Place the bit squarely into the head of the fastener. Ensure it is fully engaged to prevent cam-out.
4. 힘을 가하세요: Hold the T-handle firmly and apply smooth, steady pressure in a clockwise direction for tightening.
5. Listen for the Click: Continue applying pressure until you feel and hear a distinct "click" from the wrench. This indicates that the preset torque has been reached.
6. Stop Applying Force: Immediately stop applying force once the click is heard. Do not continue to tighten the fastener further, as this will over-torque it.
7. Remove Wrench: 렌치를 패스너에서 빼내세요.

For loosening fasteners, this torque wrench can be used as a standard T-handle wrench. However, do not use the torque mechanism for loosening, as this can affect its calibration.

6. 유지관리

• 청소: After each use, wipe the wrench body and bits with a clean, dry cloth to remove any dirt, grease, or moisture. Do not use harsh chemicals or solvents.
• 저장: Store the torque wrench and its bits in a dry, clean environment. The integrated bit storage helps keep the bits organized and protected.
• 구경 측정: Torque wrenches are precision instruments. While this model is designed for durability, periodic calibration checks by a qualified service center are recommended for professional users or if accuracy is critical.

7. 문제 해결

• 렌치가 클릭되지 않습니다: Ensure the torque setting is correctly aligned. If the fastener is already at or above the set torque, the wrench will not click. Verify the fastener's required torque.
• Bit is stuck in fastener: Ensure the bit is fully seated in the wrench's bit holder. Apply firm, even pressure when engaging the fastener. If a bit is stuck, gently wiggle and pull to remove.
• Inaccurate readings (suspected): If you suspect the wrench is not providing accurate torque, discontinue use for critical applications and consider having it checked for calibration.
