Engine Operation
Inspection after Starting the Engine
Check the pressure of the engine lubrication system by using the engine oil pressure gauge
mounted on the apparatus while the engine is in operation. If pressure decreases on oil
pressure gauge, immediately shutdown the engine. In addition, make sure that the recharge
alarm indicator lamp of the alternator is off while the engine is operating.
1. Tightly connect the +/- terminals to prevent gaps. The sheath of battery connection
cables should not be damaged or broken.
2. If the recharge alarm indicator lamp suddenly lights or blinks during engine operation
and the engine shuts down, fix the fault of the electric apparatus.
3. If color or odor of exhaust gas is unusual during operation, shutdown the engine,
diagnose the cause and fix the fault.
4. Check the engine status through the alarm indicator lamp and gauges mounted on
the apparatus during operation.
Engine Oil Pressure
If the engine oil pressure is not consistent at idle or does not reach the reference value
while the engine is operating at high speed, immediately shutdown the engine and check oil
level and leakage.
Coolant Temperature
Operating an engine with too low coolant temperature increases fuel consumption, abrasion
of the cylinder liner, and shortens the engine's life span.
Revolutions per Minute (rpm)
On an electronic control engine, the engine control unit (ECU) prevents the engine from
being operated at too high rpm over the specifications to protect the engine. The memory of
ECU has various functions which cannot be changed by operators, such as fuel flow control,
ignition time delay, and blocking of fuel and ignition.
