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 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.

Engine Warm-up
Variable Speed Engine
1. Run the engine at low idle for 3 to 5 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 fluid
leaks and air leaks. The engine may be operated
at full rated rpm and at full load when the
temperature of the water jacket reaches 60°C
(140°F).
Constance Speed Engine
1. Run the engine for 3 to 5 minutes.
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, only then apply
the load.

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.
• 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 the electrical systems.
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.
