Note
Specified grease quantity
For motors with
the option +K40 "regreasing system", the required grease quantity is stated

Danger to life as a result of parts of the body being drawn in and crushed
Operational motors can draw in body parts, crush them or cause other injuries.
• Only lubricate bearings if there is absolutely no risk to personnel.
• When working on an operational motor only wear clothes and accessories that cannot
be drawn in.
• Take the appropriate measures so that your hair cannot be pulled in by the motor,
• Only regrease the bearings at the slowest speed that can be adjusted
