Section 1. Maintenance Inspection/Check

General

1.
To make certain the generator set is always ready for operation, it must be inspected and maintained
regularly and systematically so that defects may be discovered and corrected before they result in
serious damage to components, or failure of the equipment.
WARNING
Maintenance Schedule
2.
a. General
A periodic maintenance schedule should be established and maintained. A suggested schedule is
provided in Fig. 1 on the following pages. It may be modified, as required to meet varying operating
and environmental conditions. It is suggested that generator set and vehicle inspections be
coordinated as much as possible.
b. Maintenance Schedule Check Sheet
It is strongly recommended that the customer use a maintenance schedule check sheet such as the
one in Cummins Operation Manual. The check sheet will provide a record and serve as a guide for
establishment of a schedule to meet the customer's maintenance requirements for his specific
operation.
c. Time Intervals (See Fig. 1 and 2)
The schedule is based on both hours of operation and calendar intervals. These two intervals are
not necessarily the same. For example, in normal operation the oil change period, based on hours
of operation, will be reached long before the three months calendar period. The calendar period is
included to make certain services are performed regularly when the equipment is stored, or being
operated infrequently. Lubricating oil standing in engines that are stored, or used very little, may
tend to oxidize and may require changing although it is not dirty. Perform all services on
whichever-comes-first basis.
d. Identification of Interval Periods (See Fig. 1 and 2)
Each interval period is identified by a letter A, B, C, etc., (See Fig. 2). For example, services under B
schedule should be performed at the end of each 250 hours of operation, or every three months
period, BR service is performed during the BREAK IN period (first 50-150 hours). AR service is
performed AS REQUIRED.
STOP operations at once if a serious or possibly dangerous fault is discovered.
