Starting Precautions, All Engines
WARNING
Never pour fuel or other flammable liquid into the
air inlet opening in the air intake in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury or property dam-
age.
NOTICE
Do not crank the engine for more than 30 sec-
onds at a time. Wait two minutes after each try to
allow the starter to cool. Failure to do so could
cause starter damage.
NOTE: Some starters are equipped with op-
tional overcrank protection. If overcranking oc-
curs, a thermostat breaks the electrical circuit to
the starter motor until the motor has cooled.
NOTICE
Protect the turbocharger during the start-up by
not opening the throttle or accelerating the en-
gine above 1000 rpm until minimum engine idle
oil pressure registers on the gauge. Failure to do
so could damage the turbocharger.
Cold-Weather Starting
Electronic engines do not normally require special
starting aids. At low temperatures, oil pan heaters or
water jacket heaters are sometimes used to assist in
starting. See the engine manufacturer’s operation
manual for starting aids that are approved for specific
engines.
Starting After Extended
Shutdown or Oil Change
An engine in storage for an extended period of time
(over winter, for example) may accumulate water in
the oil pan through normal condensation of moisture
on the internal surfaces of the engine. Oil diluted by
water cannot provide adequate bearing protection at
start-up. For this reason, change the engine oil and
filters after extended storage.
NOTICE
Failure to eliminate water-diluted lubricating oil
may lead to serious engine damage at startup.
Before engine start-up, complete the engine pretrip
and post-trip inspections and maintenance proce-
dures in
Chapter 11
.
Engine Break-In
Every engine is tested on a dynamometer before
shipment, eliminating the need for a break-in period.
Before running the engine for the first time, follow the
instructions in the engine manufacturer’s operation
manual.
Engine Operation
DANGER
Do not operate the engine in an area where flam-
mable vapors such as gasoline or diesel fumes
are present. Shut down the engine when in an
area where flammable liquids or gases are being
handled. Failure to observe these precautions
could result in serious injury or death.
All Freightliner diesel engines comply with the re-
quirements of the Federal (U.S.) Clean Air Act. Once
an engine is placed in service, the responsibility for
meeting both state and local regulations is with the
owner/operator.
IMPORTANT: EPA07 and EPA10 emissions
regulations apply to vehicles domiciled in
Canada and the USA at the time of printing this
manual. Vehicles that are domiciled outside of
the USA and Canada may not have EPA07- or
EPA10-compliant engines with an emission af-
tertreatment system, depending upon local
statutory emissions guidelines.
NOTICE
It is extremely important that the following points
be followed for vehicles with EPA07- or EPA10-
compliant engines, or damage may occur to the
aftertreatment device, and the warranty may be
compromised.
