2.3 NORMAL SHUTDOWN PROCEDURE
Engine speed and load should be reduced gradually. The engine should run at
idle speed 2-3 minutes after the load has been disconnected before shutting
down. If possible, avoid extended periods of idling at unloaded conditions to
prevent turbocharger carboning and exhaust slobbering.
The lube oil priming pump should be turned on for 10-15 minutes as soon as the
engine is shut down to provide continued cooling for the turbocharger bearings.
This may be an automated function in some installations - if so, the operator
should check to make certain that it is functioning as intended.
Other steps to be taken after the engine has stopped are as follows:
a. Check to make sure the governor lever is in the 'STOP' position.
b. Open the indicator cocks for each cylinder
WARNING
There is a danger of injuries being caused by contra rotation of crankshaft if
turning is carried out without opening the indicator cock or explosion check
plug. Be sure to open the indicator cock or explosion check plug when
carrying out turning.
There is a danger of your hands being pinched by the gear and cam roller of the
engine.
Never insert your hands in the course of turning.
c. Rotate the engine for 3-4 revolutions to exhaust the combustion gas from
the cylinders.
WARNING
There is a danger of parts of the body being entangled into the rotating parts or
gears of turning device in the course of turning with the turning device.
Do not allow your hand, leg, etc. to gain access to the parts.
d. Turn off the electrical power at the monitor panel.
e. Shut off the fuel service tank.
f. Close the fuel inlet valve every time. If the shutdown period will be of
a long duration, the fuel tank (s) should be drained. Also observe the
instructions in Section 2.8 for extended shutdowns.
