9.3.6 Maintenance intervals
Please note the following in order to identify faults at an early stage, rectify them and avoid
follow-on damage:
• Maintain the machine regularly and carefully.
• Inspect the machine.
• Motors must be allocated a revision/inspection number after inspection.
NOTICE
Motor failure
Material damage can occur if the machine develops faults or is overloaded.
• Immediately inspect the machine if faults occur.
• An immediate inspection is especially necessary, if the three-phase motor is excessively
stressed, either electrically or mechanically (e.g. overload or short-circuit).
The machines are equipped with permanently lubricated rolling bearings. The machine may
be equipped with a regreasing device.
CAUTION
Skin irritations and eye inammations
Many greases can cause skin irritations and eye inammations.
• Follow all safety instructions of the manufacturer.
Measures, intervals and deadlines
Measures after operating period intervals or deadlines have elapsed:
Operating situations and characteristics can vary widely. For this reason, only general
maintenance intervals are specied here. Maintenance intervals should therefore be
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).
