Usage of a torque wrench
The use of a torque wrench figure is shown in Figure 3 -4. The following points should be paid attention to
when using it:
a) Confirm that the torque of the torque wrench is correct set before use;
b) Ensure that the angle between the torque wrench and another wrench (used to support a
connector or a cable) is within 90
o
before applying force;
c) Grasp the end of the torque wrench handle gently, and apply force in the direction
perpendicular to the handle until reaching the folding point of the wrench.
