'Severe Service’ Conditions
Certain operating conditions can cause rapid degradation of the oil quality, either by the accumulation
of dirt particles, or by the absorption of water from condensation. If any of the ‘severe service’ conditions de-
scribed below apply, it is recommended that the oil and filter be changed twice as frequently as is listed in the
Maintenance Schedule.
