Maintenance
Reasons for Torque Wrench Malfunction
• Always ensure your torque wrench is maintained in a dry, clean environment.
• Store the torque wrench in the case in which it was provided.
• Use a soft cloth to clean the tool and the display.
• Dropping or shaking the torque wrench.
• Overloading the recommended torque.
• Not using the torque wrench for a long period of time.
• Using the torque wrench in serious hot or cold conditions (0˚<50˚C), humidity or
direct sunlight.
• Using it to break a bolt (undoing).
• Using it as a breaker bar.
Precautions:
• Never use an extension bar.
• Never use a length of pipe to extend the handle of your torque wrench.
• Never submerge the wrench in water.
• Never clean the wrench with organic solvents.
• Do not dismantle the wrench.
• Tighten in a slow and controlled manner and stop applying pressure immediately
the torque wrench indicates the required setting has been reached. Tightening too
quickly will result in an inaccurate final torque figure.
