4. Configuració

4.1 Desembalatge

Carefully remove the torque wrench from its durable plastic storage case. Inspect the tool for any signs of damage. Do not use if damaged.

4.2 Setting the Torque Value

  1. Locate the locking ring/button near the handle.
  2. Unlock the wrench: Rotate the locking ring counter-clockwise or pull down the locking button to unlock the adjustment mechanism.
  3. Adjust the torque: Rotate the handle to set the desired torque value. The wrench features a dual scale (ft.-lb and Nm). For precise adjustment, it is recommended to use the imperial scale (ft.-lb).
  4. Conversió: If working with Newton-meters (Nm) and the primary scale is in ft.-lb, use the conversion formula: 1 Nm = 0.738 ft.-lb.
  5. Lock the wrench: Once the desired torque is set, rotate the locking ring clockwise or push up the locking button to secure the setting. This ensures the stability of the working torque.

5.1 Aplicació del parell de torsió

  1. Attach the appropriate socket to the 1/2-inch drive square.
  2. Place the socket onto the fastener (nut or bolt).
  3. Hold the wrench by the handle and apply steady, increasing pressure in the tightening direction.
  4. Continueu aplicant pressió fins que sentiu un "clic" distintiu de la clau. Això indica que s'ha assolit el valor de parell preestablert.

6. Manteniment

  • Neteja: Wipe the wrench clean with a soft, dry cloth after each use. The polished chrome finish resists rust and corrosion and is easy to clean. Do not use abrasive cleaners or solvents.
  • Emmagatzematge: After each use, always loosen the locking ring and reset the torque setting to the lowest possible value (e.g., 20 ft.-lb or 27.1 Nm) before storing. This relieves tension on the internal spring mechanism, preserving the wrench's calibration and accuracy over time.
  • Protecció: Store the torque wrench in its original durable plastic case to protect it from dust, moisture, and impact.
  • Calibració: Torque wrenches are precision instruments and should be periodically checked for calibration by a qualified professional, especially with frequent use.
