15.1.1 Tightening torques
− All tightening torques are indicated in Nm.
− Tightening torque tolerance: ±10%.
− The tightening torques are based on a friction coef fi cient of
0.12 with a lubricated thread of the fastening elements (screws
or nuts).
− After long operating times or use at temperatures above 80°C,
the breakaway torque can be considerably higher.
