Maintenance Guidelines - Overview
General Information
Cummins Inc. recommends that the system be maintained according to the Maintenance Schedule in this section.
If the system is operating in ambient temperatures below -18°C [0°F] or above 38°C [100°F], perform maintenance at
shorter intervals. Shorter maintenance intervals are also required if the system is operated in a dusty environment or if
frequent stops are made. For gas fueled generator sets, shorter maintenance intervals are also required, if operating
at loads below 70% for prolonged periods. Contact your local Cummins® Authorized Repair Location for
recommended maintenance intervals.
Some of these maintenance procedures require special tools or must be completed by qualified personnel. Contact
your local Cummins® Authorized Repair Location for detailed information.
If your system is equipped with a component or accessory not manufactured or supplied by Cummins Inc., refer to the
component manufacturer's maintenance recommendations.
OEM supplied equipment and components can impact on the performance and reliability of the engine if they are not
correctly maintained.
Use the chart provided in this section as a convenient way to record maintenance performed.
