3.9.2 Torque Application Procedure
Good torque application technique is essential if an accurate bolt torque reading is going to be
obtained.
Firstly the nut must be tightened smoothly. Any jerks or bumps can cause the torque reading to
be obtained prematurely.
The torque must be obtained while the nut is turning. If you stop to reposition the torque wrench
and then the required torque reading is obtained without the nut turning, the nut needs to be
loosened a little and then tightened again so the torque reading is obtained while turning.
Unless specified otherwise all torque settings given in this manual are “dry” – i.e. no special
lubricant is applied to the threads or parts. Where directed otherwise it is vital that the directions
are followed exactly.
