If the grease quantity filled is not in accordance with the specified quantity,
the coupling may become an explosion hazard.
5.2 PROCEDURE BEFORE START-UP
Bolt tightening torques for the coupling and tightening torques for the
foundation bolts of the coupled machine must be checked before
startup. Enclosures (coupling protection, contact guard) must be fitted.
Overload conditions during startup cannot be excluded. If the
coupling breaks through overload, metal parts may fly off and cause
personal injury and/or material damage.
