NOTICE
Deviations from the normal state
If you detect any defects or malfunctions during the inspection, you must rectify them
immediately. They may otherwise cause damage to the machine.
9.2.4 Regreasing intervals
NOTICE
Damage to roller bearings
The regreasing intervals for roller bearings are different from the servicing intervals for the
machine. Failure to regrease the rolling-contact bearings at the specified intervals can result
in them sustaining damage.
● Comply with the regreasing intervals for roller bearings. The regreasing intervals are
specified on the lubricant plate.
9.2.5 Changing bearings when using permanently lubricated rolling-contact bearings
The replacement of the permanently lubricated roller bearing is determined by the number of
operating hours and is required around every three years.
9.2.6 Maintenance
When carrying out any work on the machine, observe the general safety instructions
(Page 13) and the specifications contained in EN 50110‑1 regarding safe operation of electrical
equipment.
9.2.6.1 Measuring the insulation resistance during the course of maintenance work
Measuring the insulation resistance and polarization index (PI) provides information on the
condition of the machine. It is therefore important to check the insulation resistance and the
polarization index at the following times:
● Before starting up a machine for the first time
● After an extended period in storage or downtime
● Within the scope of maintenance work
