NOTICE
Machine damage
When carrying out the inspection, if you detect any impermissible deviations from the normal
state, you must rectify them immediately. They may otherwise cause damage to the machine.
9.3.5
Assessing the rolling bearings
To assess the rolling bearings, it is generally not necessary to dismantle the machines. The motor
only has to be dismantled if the bearings are to be replaced.
The state of a rolling bearing can be assessed by analyzing the bearing vibration. The
measured values provide an indication and can be assessed by specialists. In this case,
contact the Service Center (Page 12).
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.
The machines are equipped with permanently lubricated rolling bearings. The machine may
be equipped with a regreasing device.
Skin irritations and eye inflammations
Many greases can cause skin irritations and eye inflammations.
• Follow all safety instructions of the manufacturer.
Measures, intervals and deadlines
Measures after operating period intervals or deadlines have elapsed:
1PC134, 1PC136 crane motors SH 132 ... 315

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).
