4.1 Attaching the Head

The torque wrench features an interchangeable head system. To attach a head:

1. Align the square drive of the desired 9x12mm head with the receptacle on the wrench body.
2. Push the head firmly into place until it clicks and is securely seated.
3. Ensure the head is fully engaged and does not wobble before use.

4.2 Ajuste del valor de torque

To set the desired torque value:

1. Descubrir: Slide the red torque locking ring downwards (towards the handle) to unlock the adjustment mechanism.
2. Ajustar: Rotate the handle. Turning clockwise increases the torque value, while turning counter-clockwise decreases it. Align the desired value on the main scale with the markings on the handle.
3. Cerrar con llave: Slide the red torque locking ring upwards (away from the handle) to lock the set torque value. Ensure it is fully locked before use; the handle should not be able to turn.

5. Instrucciones de funcionamiento

Once the desired torque value is set and the head is securely attached, you can proceed with tightening fasteners:

1. Select the appropriate interchangeable head for your fastener.
2. Place the wrench head onto the fastener, ensuring a snug fit.
3. Aplicar de forma constante e incremental.asing pressure to the handle in the tightening direction.
4. Continue applying pressure until you feel a distinct "click" and a slight release sensation from the wrench head. This indicates that the preset torque value has been reached.
5. Immediately stop applying force once the "click" is felt. Over-tightening can damage the fastener or the wrench.
6. Retire la llave del sujetador.

Important: This wrench is designed for tightening only. Do not use it for loosening fasteners.

6. Mantenimiento

• Limpieza: After each use, wipe the wrench clean with a dry, soft cloth. Do not use solvents or harsh chemicals, as these can damage the finish or internal components.
• Almacenamiento: Store the torque wrench in its original protective case in a dry, clean environment. Always set the torque to the lowest setting (3 Nm) before storing to relieve tension on the internal spring, which helps maintain accuracy over time.
• Calibración: Torque wrenches are precision instruments and require periodic calibration to maintain accuracy. It is recommended to have the wrench calibrated annually or after approximately 5,000 cycles of use, whichever comes first.
• Inspección: Regularly inspect the wrench for any signs of damage, wear, or corrosion. Do not use a damaged wrench.
