3 Screw dimensions of M8 or larger must be tightened with a torque wrench.
Screw dimensions of M6 or smaller may be tightened without a torque wrench
if this is done by trained and qualified personnel.
• Determine whether a standard tightening torque or special torque is to be
applied. The standard torques are specified in the following tables. Any
special torques are specified in the repair, maintenance or installation
procedure descriptions. Any special torque specified overrides the standard
torque!
• Use the correct tightening torque for each type of screw joint.
• Only use correctly calibrated torque keys.
• Always tighten the joint by hand, and never use pneumatic tools.
• Use the correct tightening technique, that is do not jerk. Tighten the screw
in a slow, flowing motion.
• Maximum allowed total deviation from the specified value is 10%!
Note
A special torque specified in the repair, maintenance or installation procedure
overrides the standard torque.
