Engine Operation
Proper 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 time that is needed for the engine to reach
normal operating temperature can be less than the
time taken for a walk-around inspection of the engine.
When idling after the engine is started in cold
weather, increase the engine rpm from 1000 to 1200
rpm. This idling will warm up the engine more quickly.
Maintaining an elevated low idle speed for extended
periods will be easier with the installation of a hand
throttle. The engine should not be “raced” in order to
speed up the warm-up process.
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.

Fuel Conservation Practices
The efficiency of the engine can affect the fuel
economy. Perkins design and technology in
manufacturing provides maximum fuel efficiency in all
applications. 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.
This fault will 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.
• Ensure that all of the connections of the hoses are
tight. The connections should not leak.
• Ensure that the driven equipment is in good
working order.
• Cold engines consume excess fuel. Utilize heat
from the jacket water system and the exhaust
system, when possible. Keep cooling system
components clean and keep cooling system
components in good repair. Never operate the
engine without water temperature regulators. All of
these items will help maintain operating
temperatures.
