In this article, we delve into the proper use of a pneumatic torque wrench and how to operate one safely in order to reduce the chances of sustaining a work injury.

What is a pneumatic torque wrench?

A pneumatic torque wrench operates in much the same way as an ordinary wrench, but with the added performance of an air motor and gearbox in order to absorb the torque and allow the user to remove nuts and bolts with little or no effort. They are an extremely useful devices, but can also be quite dangerous when used incorrectly.

The correct use of a torque wrench

  • First and foremost as with any dangerous tool or device, you should always wear the correct safety gear when operating a pneumatic torque wrench. The correct safety gear for using a pneumatic torque wrench consists of gloves, safety goggles, hearing protection, a hard hat, and protective footwear. Pneumatic torque wrenches have a standard operating noise level of around 103 dB so it is imperative to wear adequate hearing protection in order to reduce the chances of long-term damage to your hearing.
  • Never wear loose clothing or any jewellery when operating a pneumatic torque wrench. If you have long hair, you should consider tying this back before commencing use.
  • Before use, always inspect the device for damage, including the air hose and any associated fittings.
  • Use clean, dry air at around 90psi in order to safely operate the pneumatic torque wrench.
  • Do not over torque nuts and bolts. This should be done with a standard torque wrench.
  • Never carry a pneumatic torque wrench by the air hose.
  • Always disconnect the air hose before removing or inserting new wrench sockets or before routine maintenance.
