Engine Operation
Correct operation and maintenance are key factors in
obtaining the maximum life and economy of the
engine. If the directions in the Operation and
Maintenance Manual are followed, costs can be
minimized and engine service life can be maximized.
Variable Speed Engine
The engine can be operated at the rated rpm after
the engine reaches operating temperature. The
engine will reach normal operating temperature
sooner during a low engine speed (rpm) and during a
low-power demand. This procedure is more effective
than idling the engine at no load. The engine should
reach operating temperature in a few minutes.
Gauge readings should be observed and the data
should be recorded frequently while the engine is
operating. Comparing the data over time will help to
determine normal readings for each gauge.
Comparing data over time will also help detect
abnormal operating developments. Significant
changes in the readings should be investigated.
Constant Speed Engine
Allow the engine to warn up before applying load.
Gauge readings should be observed and the data
should be recorded frequently while the engine is
operating. Comparing the data over time will help to
determine normal readings for each gauge.
Comparing data over time will also help detect
abnormal operating developments. Significant
changes in the readings should be investigated.
Reduction of Particulate Emissions
The engine is equipped with an aftertreatment
system in order to meet emissions regulations. The
system uses a Diesel Oxidation Catalyst (DOC) in
order to meet emissions regulations. The system is
passive and will not require any operation by the
engine user. The DOC will not require a service
interval in order to operate correctly.

Fuel Conservation Practices
The efficiency of the engine can affect the fuel
economy. The design and technology in
manufacturing provides maximum fuel efficiency in
all applications. Always ensure that genuine filters
are used. Follow the recommended procedures in
order to attain optimum performance for the life of the
engine.
• Avoid spilling fuel.
Fuel expands when the fuel is warmed up. The fuel
may overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
• Be aware of the properties of the different fuels.
Use only the recommended fuels. Refer to the
Operations and Maintenance Manual, “Fuel
Recommendations”for further information.
• Avoid unnecessary idling.
Shut off the engine rather than idle for long periods of
time.
• Observe the service indicator frequently. Keep the
air cleaner elements clean.
• Ensure that the turbocharger is operating correctly
so that the proper air/fuel ratio is maintained.
Clean exhaust indicates proper functioning.
• Maintain a good electrical system.
One faulty battery cell will overwork the alternator
and can consume excess power and excess fuel.
• Ensure that the belts are properly adjusted. The
belts should be in good condition. Refer to the
Specifications manual for further information.
