2.3 Inspection and Operation of the Diesel Engine
2.3.1 Low oil pressure alarm system/ breaking device
Diesel engine possesses the low oil pressure alarm system/breaking device. When the oil
pressure goes down, the device will automatically brake the diesel engine to avoid the
blocking-up of the diesel engine because the oil pressure is too low and the lubrication is
insufficient.
If the diesel engine is running under the condition that the lubrication oil is insufficient,
the oil temperature will go up too high. On the other hand, it is also dangerous if there is
too much oil. Because the machinery oil may be burned, this will make that the
revolution speed of the engine increases suddenly and results in "abnormal fast running".
For this purpose, it is necessary to check the machinery oil and the oil level should reach
the stipulated height.
2.3.2 Trial run operation
When your diesel engine is a new set, a large loading will reduce the engine's life. Within
the first 20 hours, it is necessary to carry out the trial run.
Avoid the overload. During the trial run stage, it is necessary to avoid the large load. It uses only 75%
of the rated load.
Change the machinery oil of the engine according to the stipulation. At the beginning of the use,
change the oil once each 20-hours or once a month. After this, change the oil once each 3-months or
once for each 100-hours.
2.4 Starting the Generator Set
2.4.1 Recoil start (manual start)
Start the engine according to the following procedures:
(7) Switch on the fuel oil switch (in "ON" position).
(8) Set the speed handle of the engine at "run" position.
(9) Draw out the buffer start handle.
Draw out the handle till you feel your hand has the
resistance force. Then relieve it and let it restore to the
initial position.
Press down the pressure reduction handle (when the buffer
starter is drawn, it will automatically be restored.).
Quickly draw out the buffer start handle by two hands.
While operating (or after the start), don't let the handle fly out of your hand to avoid that
it smashes onto the diesel engine. Slowly and lightly let the handle return its position to
avoid damaging the starter.
CAUTION:
When the diesel engine is running, never draw out the start handle otherwise it will
damage the diesel engine.
In the cold days, when it is difficult to start the diesel engine, unplug the rubber cock on
the rocker arm of the diesel engine and fill in 2ml machinery oil.
Plug the rubber cock before the start.
