Note:
The strainer on the suction side of the lubricating oil pumps must be checked and cleaned,
if necessary, 24 to 48 hours of operation after the start- up of a new installation or working
on the suction side of the lubricating oil piping system.
The oil change interval depends on the following:
• Lubricating oil quality
• Engine operating conditions
• Lubricating oil consumption
• Lubricating oil filtering and centrifugal purifying
• Quantity of lubricating oil in the system
The oil change interval can be extended if allowed by the results of the oil analysis. For per-
missible analysis values (see A4.05.08.nn, Regulations and Care, Engine Lubricating Oil).
