Unless other tightening parameters are given, during maintenance repair work apply
appropriate torque to tightening nut and bolt connections. Recommended tightening torque
values for the most frequently used bolt and nut connections are given in table (5.6). Given
values apply to non-lubricated steel bolts.
TIP
Hydraulic conduits should be tightened with a torque of 50 – 70 Nm.
