PERIODIC MAINTENANCE
SCHEDULE
Daily and periodic maintenance is
important to keep the engine in good
operating condition. The following is a
summary of maintenance items by periodic
maintenance intervals. Periodic
maintenance intervals vary depending on
engine application, loads, diesel fuel and
engine oil used and are hard to establish
definitively. The following should be treated
only as a general guideline.
Engines with Low Operating
Hours
Run the engine until it reaches operating
temperature and then perform the
following maintenance procedures:
• Check the engine oil level. See Checking
Engine Oil on page 39.
• Check the coolant level. See Checking
the Coolant Level on page 42.
• Check the low pressure indicator. See
Checking the Alarm Indicators on
page 45.
• Check the fuel level. See Filling the Fuel
Tank on page 34.
• Checking the battery electrolyte level.
See Check the Battery Electrolyte Level
(Servicable Batteries Only) on page 91.
• Clean the battery. See Clean the
Battery on page 110.
• Check for any leakage, rectify as
necessary. See Check for Leakage of
Fuel, Engine Oil and Engine Coolant on
page 108.
CAUTION
Establish a periodic
maintenance plan according to
the engine application and make
sure you perform the required
periodic maintenance at
intervals indicated. Failure to
follow these guidelines will
impair the engine’s safety and
performance characteristics,
shorten the engine’s life and may
affect the warranty coverage on
your engine.
