CAUTION
DO NOT idle the engine for excessive-
ly long periods. Long periods of idling,
more than 10 minutes, can cause poor
engine performance.
Following these guidelines will help reduce
engine wear during idling and the
frequency of DPF regenerations.
Engine Shutdown
Prevent engine damage by following these
shutdown precautions.
NOTE
DO NOT shut off the engine immedi-
ately. A hot engine stores a great
amount of heat and it does not cool
down immediately after it is shut off.
Always cool the engine down before
shutting it off. You will greatly increase
its service life.
Idle the engine at 1,000 rpm for four
minutes. Then low idle for 30 seconds
before shutdown. This will allow circulating
coolant and lubricating oil to carry heat
away from the cylinder head, valves,
pistons, cylinder liners, turbocharger, and
bearings. This way you can prevent engine
damage that may result from uneven
cooling.
NOTE
For engines equipped with an elec-
tronic control module (ECM), ensure
the ignition switch is turned OFF for a
minimum of 100 seconds prior to dis-
connecting the continuous (unswitch-
ed) battery power supply. If the un-
switched battery power supply is dis-
connected in less than 100 seconds
after the ignition switch is turned OFF,
active fault codes and incorrect ECM
information may occur.
CAUTION
Failure to follow the correct shutdown
procedure may result in damage to the
turbocharger and shorten the turbo-
charger life.
Electromagnetic Interference
Information on electromagnetic
interference (EMI).
If not installed correctly, some vehicle
accessories (CB radios, mobile
transmitters, etc.) can generate and use
radio frequency energy that may cause
electromagnetic interference (EMI)
between the accessory and the
electronically controlled fuel system. Under
these conditions, PACCAR is not liable for
any performance problems with either the
fuel system or the accessory. EMI is not
considered by PACCAR to be an engine
failure and therefore is not warrantable.
System EMI Susceptibility
PACCAR products are designed and
tested for minimum sensitivity to incoming
electromagnetic energy. The fuel system
EMI susceptibility has been designed with
a high tolerance against EMI and in most
normal circumstances, if not all,
electromagnetic energy-emitting devices
that meet the Federal Communications
Commission legal requirements should
cause no interference.
