Chapter 7 MAINTENANCE SCHEDULE

How to use the maintenance schedule

Periodic inspection not only extends the service life of the engine but also serves to ensure safe operation. Be sure
to conduct inspections and maintenance according to the maintenance schedule.
The maintenance schedule shows the standard service intervals. If you notice any abnormalities such as abnormal
noise, black exhaust smoke, white exhaust smoke, extremely high temperature of exhaust gas, abnormal vibration,
and fuel, oil or exhaust gas leakage, make sure to conduct the inspection and maintenance work, regardless of rec-
ommended service intervals in the "Maintenance schedule."
Note: Appropriate service intervals vary depending on the usage and operating conditions as well as consumption
of fuel, oil and coolant. Check the operating record of the engine to determine the most appropriate service
intervals. (Feel free to consult a dealer of Mitsubishi Heavy Industries, Ltd. regarding service intervals.)
Service the items at multiples of the original requirement. For example, at 1000 service hours, also service those
items listed under every 250 service hours and every 50 service hours.
Items marked with * in the maintenance schedule require special tools or large equipment. For the servicing of
those items, contact a dealer of Mitsubishi Heavy Industries, Ltd.
