Stopping The Engine; Emergency Jump Starting - Detroit Diesel 60 Series Operator's Manual

Avoid Unnecessary Idling
CAUTION:
Diesel engine exhaust and some
of its constituents are known to
the state of California to cause
cancer, birth defects and other
reproductive harm.
Always start and operate the
engine in a well-ventilated area.
If operating the engine in an
enclosed area, vent the exhaust
to the outside.
Do not modify or tamper with
the exhaust system or emission
control system.
During long engine idling periods with the
transmission in neutral, the engine coolant
temperature may fall below the normal
operating range. The incomplete com-
bustion of fuel in a cold engine will cause
crankcase dilution, formation of lacquer or
gummy deposits on the valves, pistons,
and rings, and rapid accumulation of
sludge in the engine. When prolonged
idling is necessary, maintain at least 850
rpm spring/summer and 1200 rpm
fall/winter.

Stopping the Engine

Normal Stopping
1. Decrease engine speed back to normal
idle and put all shift levers in the neutral
position.
2. Allow the engine to run between idle
and 1000 rpm with no load for four or
five minutes. This allows the engine to
cool and permits the turbocharger to
slow down. After four or five minutes,
shut down the engine.
NOTICE:
Stopping a turbocharged engine
immediately after high speed opera-
tion may cause damage to the tur-
bocharger, as it will continue to turn
without an oil supply to the bearings.
Emergency Jump
Starting
DDEC III and DDEC IV electronic con-
trol systems operate on 12 or 24 volts
DC. If a DDEC III or IV engine with an
electronic starting motor requires emer-
gency jump starting, do not exceed 32
volts DC.
NOTICE:
Jump starting with voltages greater
than those indicated or reversing
battery polarity may damage the
ECM (Electronic Control Module).
