Información de seguridade

Always observe the following safety precautions to prevent injury and damage to the tool or workpiece.

• Usar o equipo de protección individual (EPI) axeitado, such as safety glasses, when using the torque spanner.
• Do not exceed the maximum torque capacity of 210 Nm. Overloading can damage the tool and lead to inaccurate readings.
• Ensure the fastener and socket are clean and free of debris before applying torque.
• Do not use the torque spanner as a breaker bar or for loosening seized fasteners. This can damage the internal calibration mechanism.
• Keep the tool clean and dry. Moisture and dirt can affect its performance and longevity.
• Store the torque spanner in its protective case cando non estea en uso para evitar danos.

2. Preparación para o seu uso

• Select the correct size socket for your fastener.
• Attach the socket firmly to the 1/2" square drive head.
• Ensure the fastener and mating surfaces are clean and free of oil or grease, unless specified by the manufacturer.

Instrucións de funcionamento

1. Axuste do valor de par

1. Desbloquear a manivela: Locate the locking mechanism (often a knurled ring or screw at the base of the handle) and turn it to the unlocked position.
2. Adjust the Torque: Rotate the handle to set the desired torque value. The main scale on the shaft indicates major increments (e.g., 40, 50, 60 Nm), and the smaller scale on the handle provides fine adjustments. Align the desired main scale value with the top edge of the handle, then rotate the handle until the fine adjustment mark aligns with the center line of the main scale. The magnifier window assists in precise reading.
3. Bloquear a manivela: Once the desired torque is set, turn the locking mechanism back to the locked position to prevent accidental changes during use.

2. Aplicación do par de torsión

• Coloque o encaixe no fixador.
• Apply a steady, smooth pull to the handle. Avoid jerky movements.
• Continue pulling until you feel and hear a distinct "click" or "break" in the handle. This indicates that the preset torque value has been reached.
• Immediately stop applying force once the click is felt/heard. Do not continue to tighten.
• Remove the torque spanner from the fastener.

Nota: For critical applications, it is recommended to tighten fasteners in stages (e.g., 50%, 75%, 100% of the final torque) to ensure even seating and accurate torque application.

Mantemento

1. Limpeza

After each use, wipe the torque spanner clean with a soft, dry cloth. Do not use solvents or abrasive cleaners, as these can damage the finish or internal components. Ensure no dirt or debris accumulates in the adjustment mechanism or drive head.

2. Almacenamento

When not in use, always store the torque spanner in its original protective case. This protects it from dust, moisture, and accidental impacts. It is recommended to set the torque value to its lowest setting (but not below the minimum) before storage to relieve tension on the internal spring mechanism, which can help maintain calibration accuracy over time.

3. Calibración

Torque wrenches are precision instruments and require periodic calibration to ensure accuracy. The frequency of calibration depends on usage, but generally, it is recommended to have the tool calibrated annually or after approximately 5,000 cycles, whichever comes first. Refer to a qualified calibration service for this procedure.
