9.2 Intervals for maintenance and inspections
The following intervals are guide values.
Adapt intervals to the respective operating conditions.
Agree on longer intervals with the manufacturer.
Before longer downtimes, lubricate all lubrication points.
For 3-shift operation or in case of heavy loading of the seals,
lubricate monthly. This may be necessary in roller mills due
to the special operating conditions (e.g. water, steam,
cinders, dust).
In case of use in paper machines with permanent operation,
lubricate the universal joint shafts every two months.
