5.1. Setting the Torque Value

The torque wrench features an intuitive three-step system for setting the desired torque:

1. Кулпуну ачуу: Press down on the locking ring located at the base of the handle.
2. Тууралоо: Rotate the handle. Turning it clockwise increases the torque value, while turning it counter-clockwise decreases it. Align the desired torque value on the main scale with the zero mark on the micro-scale. For fine adjustments, use the micro-scale.
3. Кулпу: Once the desired torque value is set, release the locking ring to secure the setting. Ensure the locking ring springs back into place to prevent accidental changes during use.

5.2. Installing and Removing Sockets

The torque wrench is equipped with a quick-release mechanism for efficient socket changes:

1. Орнотуу: Press the quick-release button on the ratchet head and firmly push the desired socket onto the square drive. Release the button to lock the socket in place.
2. Алып салуу: Press the quick-release button again and pull the socket off the square drive.

6.1. Selecting Direction

The ratchet head allows for bi-directional operation:

• Move the switch on the ratchet head to the left for counter-clockwise operation.
• Move the switch to the right for clockwise operation.

6.2. Моментти колдонуу

1. Ensure the correct torque value is set and locked.
2. Attach the appropriate socket to the fastener.
3. Hold the wrench by the handle and apply steady, increasing pressure until you hear and feel a distinct "click." This click indicates that the preset torque has been reached.
4. Stop applying force immediately after the click. Do not continue to tighten the fastener beyond this point.

7. Техникалык тейлөө

• Тазалоо: After each use, wipe the wrench clean with a dry, soft cloth. Do not use harsh chemicals or solvents that could damage the finish or internal components.
• Майлоо: The internal mechanism is factory-lubricated. Do not attempt to lubricate the internal parts unless specifically instructed by a qualified technician.
• Сактагыч: Always store the torque wrench in its protective case in a dry, clean environment. Set the torque to its lowest setting (but not below) before storing to relieve spring tension and maintain calibration accuracy over time.
• Калибрлөө: Torque wrenches are precision instruments and should be recalibrated periodically (e.g., annually or after significant use) by a certified service center to ensure continued accuracy.

8. Кыйынчылыктарды

If you encounter issues with your torque wrench, consider the following:

• No "Click" Sound: Ensure the torque value is set correctly and locked. Apply steady, increasing force; a quick jerk might prevent the click from being felt or heard. If the issue persists, the wrench may require recalibration or service.
• Inaccurate Torque: Verify the torque setting. Ensure the wrench is used correctly (not as a breaker bar). Recalibration may be necessary if accuracy is consistently off.
• Difficulty Adjusting Torque: Check if the locking ring is fully disengaged. Clean any debris from the adjustment mechanism. If the mechanism is stiff, a small amount of light machine oil might help, but avoid over-lubrication.
