Normal Starting Procedure; Engine Shutdown - Perkins 4006 User Handbook Manual

NORMAL STARTING PROCEDURE

Ensure any engine control switch is set to the
run position, with the load disengaged.
Manually set the air shut-off valve (if fitted) to
the run position (see Fig. 18). Turn the
keyswitch to the start position, which will
energise the solenoid allowing the engine to
crank over for a few seconds then start.
Check the instrument panel is showing
normal running oil pressure, and the
ammeter for charge to the engine batteries
(see pages 22-25).
Allow the engine to run for five minutes
checking the instruments are
correctly. Stop the engine and check the oil
and coolant levels, replenish if necessary
(see pages 19-20).

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 solenoid to stop the
engine. The solenoide remains de-energised
until the engine is started up again.
With the manual system the stop control
must be held in the stop position until the
engine stops. Manual stopping can be used
to override the
necessary.
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.

OPERATING INSTRUCTIONS
Fig. 18
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 the engine
on load can cause seizure of bearings and
damage to oil seals.
WARNING
EXCESSIVELY AT LOW SPEEDS OR
LOADS. IF THE ENGINE IS NOT BEING
USED SHUT IT DOWN.
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.
