Engine Operation
General 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.
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.
NOTICE
The engine and emissions control system shall be
operated, used, and maintained in accordance with
the instructions provided. Failure to follow the instruc-
tions could result in emissions performance that does
not meet the requirements applicable to the category
of the engine. No deliberate tampering with, or mis-
use of the engine emissions control system should
take place. Prompt action is critical to rectify any in-
correct operation, use, or maintenance of the emis-
sions control system.

Engine Warm-up
1.
Run the engine at low idle for three to five minutes,
or run the engine at low idle until the jacket water
temperature starts to rise.
More time may be necessary when the
temperature is below −18°C (0°F).
2.
Check all of the gauges during the warm-up
period.
3.
Perform another walk-around inspection. Check
the engine for fluid leaks and air leaks.
4.
Increase the rpm to the rated rpm. Check for fluid
leaks and air leaks. The engine may be operated
at full rated rpm and at full load when the jacket
water temperature reaches 60°C (140°F).

Engaging the Driven
Equipment
1.
Operate the engine at one-half of the rated rpm,
when possible.
2.
Engage the driven equipment without a load on the
equipment, when possible.
Interrupted starts put excessive stress on the drive
train. Interrupted starts also waste fuel. To get the
driven equipment in motion, engage the clutch
smoothly with no load on the equipment. This
method should produce a start that is smooth and
easy. The engine rpm should not increase and the
clutch should not slip.
3.
Ensure that the ranges of the gauges are normal
when the engine is operating at one-half of the
rated rpm. Ensure that all gauges operate
properly.
4.
Increase the engine rpm to the rated rpm. Always
increase the engine rpm to the rated rpm before
the load is applied.
5.
Apply the load. Begin operating the engine at low
load. Check the gauges and equipment for proper
operation. After normal oil pressure is reached and
the temperature gauge begins to move, the engine
may be operated at full load. Check the gauges
and equipment frequently when the engine is
operated under load.
Extended operation at low idle or at reduced load
may cause increased oil consumption and carbon
buildup in the cylinders. This carbon buildup
results in a loss of power and/or poor
performance.

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 to
attain optimum performance for the life of the engine.
