Checking The Operation Of The Diesel Engine; Starting The Generator Set - ETQ DG4LE Owner's Manual

Before you start the engine, please
fill the fuel tank and engine oil first.
Then, check to see if there are air
bubbles in the engine. If there are,
follow these procedures. Loosen the
connecting nut between the oil
injection pump and oil pipe. Bleed
the air from the system until there
are no more bubbles. Then replace
the connecting nut and tighten it.
2-3 Checking the operation of the
diesel engine
2-3.1 Low-pressure alarm system.
ETQ diesel engines have a low-
pressure sensor system where if
the oil pressure drops too low,
the sensor will shut the engine
off. The purpose of having this
system is to ensure that the
engine does not seize up. If there
is not enough oil in the engine,
the temperature of the oil will be
raised too high. On the contrary,
if there is too much oil in the
engine, the engine oil can slow
the engine down considerably.
