CAUTION
Skin irritations and eye inflammations
Many greases can cause skin irritations and eye inflammations.
•
Follow all safety instructions of the manufacturer.
The machines are equipped with permanently lubricated roller bearings. A regreasing device
is optional.
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.
Operating situations and characteristics can vary widely. For this reason, only general
maintenance intervals are specified here. Maintenance intervals should therefore be
scheduled to suit the local conditions (dirt, starting frequency, load, etc.).
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).
