2. Informació de seguretat

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

• Llegeix el manual: Familiarize yourself with all instructions and warnings before operating the torque wrench.
• Equip de protecció: Utilitzeu l'equip de protecció individual adequat, com ara ulleres de seguretat, quan utilitzeu l'eina.
• Aplicació adequada: Use the torque wrench only for its intended purpose of applying controlled torque. Do not use it as a standard ratchet or for breaking loose seized fasteners.
• Over-Torquing: Never exceed the maximum specified torque value (50 Nm) for this wrench. Over-torquing can damage the fastener, workpiece, or the tool itself.
• Neteja: Keep the tool clean and free from oil, grease, or other contaminants that could affect its accuracy or your grip.
• Emmagatzematge: Store the torque wrench in a dry, clean environment, preferably in its protective case, and set to the lowest torque value (or zero if applicable) to relieve spring tension.
• Calibració: Torque wrenches are precision instruments and should be periodically checked and calibrated by qualified personnel to maintain accuracy.

4. Configuració

1. Desembalatge: Traieu amb cura la clau dinamomètrica del seu embalatge. Inspeccioneu-la per veure si hi ha signes de danys.
2. Familiarització: Locate the torque adjustment mechanism, the scale, and the ratchet direction switch.
3. Adjunt: Select the appropriate socket or bit for your fastener and attach it securely to the square drive of the ratchet head.

5. Instruccions de funcionament

5.1 Setting the Torque Value

1. Unlock Adjustment: Rotate the green ring at the end of the handle to unlock the adjustment mechanism.
2. Adjust Coarse Setting: Rotate the handle to move the main scale indicator to the desired coarse torque value (e.g., 20 Nm).
3. Adjust Fine Setting: Use the fine adjustment scale on the handle to precisely set the final torque value. The audible and tactile clicks on reaching the scale values assist in accurate setting.
4. Ajust de bloqueig: Once the desired torque is set, rotate the green ring back to lock the adjustment mechanism. This prevents accidental changes during use.

5.2 Using the Torque Wrench

1. Ratchet Direction: Ensure the ratchet direction switch is set for clockwise rotation for tightening.
2. Aplicar força: Apply steady, smooth force to the handle. Avoid jerky movements.
3. Click Indication: Continue applying force until you hear and feel a distinct "click" from the wrench. This indicates that the preset torque value has been reached.
4. Atura: Immediately stop applying force once the click is felt/heard. Do not continue to tighten the fastener beyond this point.
5. Restablir: After each use, the wrench automatically resets for the next application.

6. Manteniment

• Neteja: Wipe the wrench clean with a soft, dry cloth after each use. Do not use harsh chemicals or solvents.
• Lubricació: The internal mechanism is factory-lubricated. Do not attempt to lubricate the internal components yourself unless specifically instructed by Wera.
• Emmagatzematge: Always return the torque wrench to its lowest torque setting (10 Nm) before storing to relieve tension on the internal spring, which helps maintain accuracy over time. Store in a protective case in a dry environment.
• Inspecció: Periodically inspect the wrench for any signs of wear, damage, or loose parts. Do not use a damaged tool.

7. Solució De Problemes

If you encounter issues with your Wera Click-Torque B1, consider the following:

• No Click Sensation:
  • Ensure the torque value is set correctly and locked.
  • Verify you are applying steady, increasing force.
  • The fastener might already be at or above the set torque.
• Lectures inexactes:
  • Check if the wrench has been dropped or subjected to impact.
  • Ensure the wrench is clean and free from debris.
  • Consider professional calibration if accuracy is consistently questionable.
• Ajust rígid:
  • Ensure the adjustment mechanism is unlocked before attempting to change the torque setting.
  • Clean any dirt or grime from the adjustment area.

For issues not resolved by these steps, contact Wera customer support.
