OPERATING THE DIESEL GENERATOR
2-2.5 Checking the generators
Before starting the generator, make sure the breaker is in the "OFF" position,
Starting the generator with the breaker in the "ON" position is very dangerous.
Use dry compressed air (with pressure about 1 96 x 105 Pa) to blow the dust
out in the control panel and at the surface of the alternator.
According to the electric wiring diagram, check to see whether the connecting
wire is correct and the connected place is firm.
WARNING
The generator should be grounded in order to prevent electric shock.
2-3 Checking the operation of the diesel engine
2-3.1 Low-pressure alarm system.
Dynamo Power 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.

When you purchase a brand new
engine, the engine must be properly broken in. The break in period is about 20
hours.
(1) Avoid overloading the engine when brand new. After primely start the
genset, please make the engine warm-up about 5 minutes. Do not load a
high-power device to the genset during breaking in. A speed of 3600rpm and 50%
load are recommended for breaking in.
(2) Change the engine oil according to specifications. An oil change for a brand
new engine is about 20 hours or one month, an older engine, the oil change is
about 100 hours or three months.(see fig 9)
