Threaded Connections

Always use a torque wrench to tighten the threaded connections.
The tightening torques of all of the standard threaded connections can be found listed on
page 48.
IMPORTANT!
Damage to components caused by incorrectly tightened threaded connections
For this reason:
S If an impact wrench is used for the initial tightening, then the bolts may only be
tightened with a max. of 50% of the specified tightening torque.
S The final tightening stage may only be performed manually using a torque wrench.
