Starting After Extended Shutdown or
Oil Change
NOTE: An engine in storage for an extended
period of time (over winter, for example) may
accumulate water in the oil pan. Oil diluted by
water cannot provide adequate bearing protec-
tion at start-up. For this reason, change the en-
gine oil and filters after extended storage.
Do the following steps after an oil change or
after the engine has been shut down for more
than three days:
1. Make sure the transmission is filled with the cor-
rect type of fluid, as recommended by the trans-
mission manufacturer.
2. Make sure the fuel tank is full. If air has entered
the fuel system, prime the fuel system, using the
engine manufacturer's instructions.
3. If the engine is equipped with a fuel/water sepa-
rator, drain off any accumulated water.
4. Check the drive belts to make sure they are in
good condition and properly adjusted. Replace
any drive belts that are cracked, worn, or glazed.
5.
Check the turbocharger for signs of oil or ex-
haust leaks. Correct any problems before starting
the engine.
6. Check the engine mounting bolts for tightness.
Retighten them if necessary.
7. Make sure the battery cable connections are
clean and tight. Check that the batteries are
charged.
8. Start the engine. See the "Engine Starting" head-
ing in this chapter.
Engine Operation
IMPORTANT: For cold-weather starting, engine
break-in, and cold-weather operation, refer to
the Cummins or Mercedes-Benz engine manu-
facturer's operator's manual, as applicable, for
detailed instructions.
Operating vehicles in areas where there are concen-
trated flammable vapors (such as diesel, gasoline, or
propane fumes) can create a hazardous situation.
These vapors can be drawn into the engine through
the air intake, and cause engine overspeed. Be es-
pecially cautious of low-lying or closed-in areas, and
always check for signs that flammable vapors may
be present.
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 diesel engines have been built to 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. Good operating practices, regular
maintenance, and correct adjustments are factors
that will help to stay within the regulations.
Adequate maintenance of the engine, which is the
responsibility of the owner/operator, is essential to
keep the emission levels low.
The driver should be familiar with the vehicle warning
system in order to bring the vehicle to a safe stop if
the engine malfunctions. If the driver doesn't under-
stand how the warning system works, an engine
shutdown could occur, causing a safety hazard. See
Chapter 3 for information on the control panel for
these engines.
Follow the directions in the Cummins or Mercedes-
Benz engine manufacturer's operator's manual and
in this manual for trouble-free, economical vehicle
engine operation.
NOTICE
Stop the engine at the first sign of malfunction.
Almost all malfunctions give some warning to the
operator before significant damage occurs. Many
engines are saved because alert operators heed
the warning signs (sudden drop in oil pressure,
unusual noises, etc.) and immediately shut down
the engine.
1. Cummins and Mercedes-Benz diesel engines are
designed to operate successfully at full throttle
under transient conditions down to rated rpm.
This is consistent with recommended operating
practices.
