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.

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.
•
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.
•
Maintain a good electrical system.
One damaged battery cell will overwork the alternator.
This will consume excess power and excess fuel.
•
Ensure that the drive belts are correctly adjusted.
The drive belts should be in good condition.
•
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.
