Notes: (1) The oil should be changed at these intervals, unless oil analysis results exceed the allowable limits. The frequency of changes will depend on the system cleanliness.

(2)Oil analysis should be done at these intervals as a minimum; the frequency of analysis will depend on system cleanliness.

(3)The oil filter(s) on a minimum must be changed at these intervals or annually if not run continuously. However, the oil filter(s) must be changed if the oil filter differential exceeds 12 psi or oil analysis requires it.

NOTE: See Motor Manual for proper lubrication procedures and service intervals.
