OPERATING INSTRUCTIONS
4012/16 Diesel, February 1997 3

ENGINE SHUTDOWN
The engine is normally stopped by operating
an electric stop control via a key switch. In
this case it is only necessary to turn the key
in an anti-clockwise direction which de-
energises the stop solenoids to stop the
engine. The solenoids remain de-energised
until the engine is started up again.
NOTE: For engines fitted with Regulateurs
Europa 2100, Woodward UG 10 or 3161
hydraulic governors, the 'stop' solenoids are
built into the governors and they are
energised to stop (ETS) the engine and de-
energised shortly after the engine stops.
Should the engine stop due to the air shut-off
valves being operated, it is imperative that
the cause of the fault be investigated
immediately.
It is essential to allow the engine to run at no
load for 3 - 5 minutes before stopping to
allow the circulating lubricating oil to take the
heat away from the bearings and shafts, etc.
This is especially important with
turbocharged engines where extremely high
temperatures are experienced within the
turbocharger. Heat rise by suddenly
stopping an engine on load can cause
seizure of bearings and damage to oil seals.
NOTE: Excessive idling of the engine will
result in only partial burning of the fuel,
causing high carbon build-up on injector
nozzles, valves, piston rings, etc. Also
unburnt fuel will tend to wash the
lubricating oil from cylinder bores and
dilute the oil in the sump. This can
eventually cause inefficient lubrication of
bearings and result in seizure.
WARNING
DO NOT RUN THE
ENGINE AT LOW
SPEEDS OR LOADS. IF THE ENGINE IS
NOT BEING USED SHUT IT DOWN.
