OPERATION INSTRUCTIONS (Continued...)
A-1C.
ENGINE OPERATION
After the engine starts, and at frequent intervals while the engine is operating, the gauges
should be observed. Determine the normal reading for each gauge. Investigate the cause
whenever there is a significant change in the reading.
Tachometer
The tachometer indicates engine RPM. The high idle RPM and the full load RPM are stamped
on the engine's information plate. The engine can be operated between these two speed
limits for long periods of time without shortening engine life. Prolonged operation at high idle
with little or no load can cause adverse engine operation.
Engine Oil Pressure
If the gauge reading fluctuates after the load is stable:
1. Remove the load.
2. Reduce engine speed to low idle.
3. Observe the oil level. Maintain the oil level between the ADD and FULL mark on the
dipstick. If the reading continues to fluctuate when the oil level is correct, stop engine and
call your Caterpillar dealer.
Engine Jacket Water Temperature
The engine should operate within the NORMAL (green) range. If the engine is operating in
the (red) range and steam becomes apparent:
1. Reduce the load and engine RPM.
2. Inspect for coolant leaks.
3. Determine if the engine must be shut down immediately; or if the engine can be safely
cooled by reducing the load. (See COOLING SPECIFICATION INSTRUCTIONS.)
CAUTION: Do not add cold water to a hot engine: Cracking of engine components may
occur. Allow the engine to cool, then add coolant.
