How many times should a torque wrench be pulled to warm it up properly?

3 times

6 times

8 times

10 times

A torque wrench should be pulled to warm it up properly to ensure accurate readings. The ideal practice is to pull the wrench multiple times, specifically up to 10 times. This process helps to stabilize the internal components of the wrench and allows lubricants to be evenly distributed, resulting in more consistent torque application.

This warming-up procedure is crucial because it helps remove any potential variances that could occur due to the differences in temperature, pressure, and the condition of the tool. By the time you pull it 10 times, you enhance the reliability and precision of the torque measurements you will obtain during actual tasks.

The other choices indicate a lower number of repetitions, which may not provide sufficient time for the wrench to reach a stable operating state. Thus, pulling a torque wrench 10 times is recommended for optimal performance and accuracy.
