Starting The Engine; Engine Operation - Bison BS-20KVA Operation Manual

(6) In the event of chill and freezing temperature, diesel engine must be put in a warm place resisting
cold and freeze. When engine is operating in the open air, warm up the oil pan and heat the cooling liquid
before starting the engine.

10.3 Starting the engine

(1) Don't start the engine until all the preparation works are completed complying with the
requirements. Start the engine as the following procedures:
Pull the locking-type switch to start the engine. To protect the starter and battery, each start cannot
exceed 15 seconds. For each failure of start, wait at least 120 seconds before another attempt. In the
event of three consecutive start failures, please find out the reasons and troubleshoot the failure before
another start.
When engine is started at a temperature lower than -5℃, please switch on the air inlet electrical heater
for 30 seconds before starting the diesel engine (The heater can be turned on during the engine start, but
it's better not to run it for more than 45 seconds in total).
Please release the start button immediately after the engine is started and put the locking-type switch
back to where it originally was.
(2) Check the oil pressure after the engine is started.
When engine is running at idle speed, make sure that oil pressure for BS-30KVA diesel engine and
BS-50KVA diesel engine must be respectively no less than 78KPa and 98KPa. For newly-assembled
diesel engine, please check the oil level for oil pan and add the oil if necessary to ensure that the oil level
is between the upper and lower mark of oil gauge.

10.4 Engine operation

(1) Run the engine at idle speed for 3 to 5 minutes and check the sealing performance for its joints of
fuel and water pipelines. Please repair it if any leakage is discovered. Make the engine run at the rated
speed with less than 30% load. Pay attention to the oil pressure (oil pressure for 4DW diesel engine and
4DX diesel engine must be no less than 280KPa and 350KPa) and temperature of cooling liquids. In the
event that the cooling liquid temperature is higher than 60 degree, run the engine with more load.
(2) For new engine or engine experiencing overhaul, don't run it with full load before 40 hours of
low-load operation.
(3) Don't operate the diesel engine at idle speed for long term, especially for supercharged diesel engine.
Excessively low oil pressure will increase the abrasion of its supercharger bearing.
