6.1 Periodic Maintenance
Periodic (preventive) maintenance reduces
the risk of unexpected stoppages and
breakdowns. Follow the maintenance log in
this chapter in order to facilitate the
periodic maintenance.
6.1.1 Maintenance intervals
The following directions for periodic
maintenance give a brief description of parts to
be cleaned, checked and renewed at different
maintenance intervals.
The maintenance log for each maintenance
interval on page
43 gives a detailed list of
actions to be performed.
Inspection
An Inspection consists of an overhaul of the
separator bowl, inlet/outlet and operating
water device every 6 months or 4000 operating
hours.
Seals in bowl and gaskets in inlet/outlet device
are renewed.
Overhaul
An Overhaul consists of an overhaul of the
complete separator (including separator bowl,
inlet/outlet and operating device) every 18
months or 12000 operating hours. Seals,
bearings, friction blocks and flat belt in the
separator are renewed.
Oil change
The oil should be changed every 4000 hours, or
at least once every year if the total number of
operating hours is less than 4000 hours/year.
6.1.2 Maintenance procedures
At each Inspection and/or Overhaul, take a
copy of the maintenance log and use it to make
notes during the service.

Place the separator parts on clean, soft
surfaces such as pallets.
