if oil pressure does not build within approxi-
mately ten seconds. Check to determine the
cause of the problem. Operating the engine with
no oil pressure will damage the engine.
6. It is not necessary to idle the engine before en-
gaging or starting the operation, but load should
be applied gradually during the warm-up period
until the oil temperature reaches 140°F (60°C).
7. Apply load gradually during the warm-up period.
NOTICE
If the oil pressure gauge indicates no oil pres-
sure, shut down the engine within approximately
ten seconds to avoid engine damage.
8. Check the oil pressure gauge for any drop in lu-
bricating oil pressure or mechanical malfunction
in the lubricating oil system. Minimum oil pres-
sure at idle is 7 psi (50 kPa).
Cold-Weather Starting
See the engine manufacturer’s operation manual for
starting aids that are approved for specific engines.
Starting After Extended Shutdown
Before engine start-up, complete the engine pretrip
inspections in
Chapter 25 .
NOTICE
Failure to eliminate water-diluted lubricating oil
may lead to serious engine damage at startup.
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.
Engine Operation
Safety and Environmental
Considerations
WARNING
Do not operate the engine in an area where flam-
mable vapors such as gasoline or diesel fumes
are present. Shut off 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 engines on Freightliner vehicles comply with the
requirements of the Federal (U.S.) Clean Air Act.
Once an engine is placed in service, the responsibil-
ity for meeting both state and local regulations is with
the owner/operator.
IMPORTANT: Depending upon local jurisdic-
tional emissions guidelines, vehicles that are
domiciled outside of the U.S. and Canada may
not have engines and/or emissions aftertreat-
ment systems that are compliant with EPA10 or
GHG21 regulations.
NOTICE
It is extremely important that the following guide-
lines be followed for engines that comply with
EPA07 or newer regulations, or damage may
occur to the aftertreatment device, and the war-
ranty may be compromised.
•
Use ultralow-sulfur diesel with 15 ppm sul-
fur content or less.
•
Do not use fuel blended with used engine
lube oil or kerosene.
•
Use only engine lube oil with a sulfated ash
level less than 1.0 wt%; API CJ-4, CK-4, and
FA-4 oils meet this requirement.
A Top Tier
™
compliant fuel is recommended. Look for
the symbol that denotes a Top Tier compliant fuel;
see
Fig. 12.3 .
Adequate maintenance of the engine and the diesel
particulate filter (DPF) are the responsibility of the
owner/operator, and are essential to keep the emis-
sion levels low. Good operating practices, regular
maintenance, and correct adjustments are factors
that will help keep emissions within the regulations.
The driver should be familiar with the vehicle warning
system in order to bring the vehicle to a safe stop if
