Engine Operation
Correct oper
ation 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 ca
n 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 r
ecorded 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.

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 a walk-around inspection. Check the
engine for fluid leaks and air leaks.
4. Increase the rpm to the rated rpm. Check for
fluidleaksandairleaks.Theenginemaybe
operated at full rated rpm and at full load when
the temperature of the water jacket reaches 60°C
(140°F).

Fuel Conservation P rac tices
The efficiency o
f the engine can affect the fuel
economy. Perkins design and technology in
manufacturing provides maximum fuel efficiency in
all applicati
ons. 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
air cleaner service indicator frequently.
Keep the air cleaner elements clean.
•
Maintain th
e electrical systems.
One damaged battery cell will overwork the alternator.
This will co
nsume excess power and excess fuel.
•
Ensure that the drive belts are correctly adjusted.
The drive be
lts 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 or
der.
•
Cold engines consume excess fuel. Utilize heat
from the ja
cket water system and the exhaust
system, when possible. Keep cooling system
components clean and keep cooling system
component
s in good repair. Never operate the
engine without water temperature regulators.
All of these items will help maintain operating
temperat
ures.
