7 SCHEDULED MAINTENANCE
This chapter describes the scheduled maintenance schedule in which details of the scheduled maintenance and
its cycle are listed up.
How to Use the Scheduled
Maintenance
Scheduled maintenance not only extends the
service life of the engine but also serves to ensure
the safe operation. Be sure to conduct the
inspection and maintenance in accordance with the
"SCHEDULED MAINTENANCE". However, if you
notice abnormalities as shown below, be sure to
conduct the inspection and maintenance work
regardless of recommended service intervals in the
"SCHEDULED MAINTENANCE".
•Noise
• Significant black or white exhaust smoke
• Abnormal exhaust gas temperature
• Abnormal vibration
• Fuel leaks
• Engine oil leaks
• Exhaust gas leaks
• Appropriate service intervals vary with
usage and operating conditions as well
as conditions of fuel, oil, and coolant.
Check the results and shorten the
interval as necessary.
When a certain service interval arrives, check and
service the inspection and maintenance items not
only for the applicable interval but also for the
earlier intervals. For example, in the 2000 hour
interval, check and service the items listed in every
50, 250, 500, and 1000 hours.
Do not take actions for items
indicated as "Contact your MHIET
dealer" in the measure column in the
Scheduled Maintenance.
* Otherwise, serious accident, environmental
pollution, or damage to the devices may occur.
Be sure to contact your MHIET dealer.
Be sure to perform the pre-operation
check and scheduled maintenance as
instructed in this Operation &
Maintenance Manual.
* Failure to perform the pre-operation check and
scheduled maintenance may cause various
engine problems and breakage to parts, which
may result in serious accidents.
