MAINTENANCE GUIDELINES

Maintenance Guidelines -Overview

Cummins Inc. recommends that the engine be maintained
according to the Maintenance Schedule in this section.
If the engine 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
engine is operated in a dusty environment or if frequent stops
are made. 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 engine is equipped with a component or accessory not
manufactured by Cummins Inc., refer to the component
manufacturer's maintenance recommendations.
Use the chart provided in this section as a convenient way to
record maintenance performed.
