its use, handling, and storage. Many starting flu-
ids are in capsules or pressure cans, and im-
proper usage can be dangerous.
Do not attempt to use any type of vapor-
compound start system near heat or open flame.
Engine damage due to an explosion or fire in the
intake manifold could result.
Do not breathe the ether fumes; doing so could
result in personal injury.
Turn the ignition switch to the on position. See
Fig. 7.7.
If the engine doesn’t start after 30 seconds of crank-
ing, turn the key to the off position and wait two min-
utes; then repeat the starting procedure.
If the coolant temperature is less than 64°F (18°C),
the engine will start up in the cold-start strategy. This
reduces the amount of fuel available to the injectors,
advances the timing, and controls white smoke emis-
sions. The engine remains in the cold-start strategy
until the coolant temperature rises above 64°F
(18°C), or until it has been running for 12 minutes.
IMPORTANT: Do not move the vehicle when it
is in the cold-start strategy. Power will be notice-
ably reduced.
After a cold engine start of less than 64°F (18°C),
Caterpillar electronic engines automatically idle at
800 rpm (for C–10 and C–12 engines), or 600 rpm
(for 3406E, C–15, and C–16 engines). These elec-
tronic engine systems will adjust the idle speed to
700 to 750 rpm when the engine is warm enough to
drive the vehicle.
Detroit Diesel S60
The engine may require the use of a cold-weather
starting aid if the outside temperature falls below
40°F (4°C).
Turn the ignition switch to the on position and start
the engine.
If the engine doesn’t start after 30 seconds of crank-
ing, turn the key to the off position and wait two min-
utes; then repeat the starting procedure.
Run the engine slightly above idle until oil pressure
shows on the gauge. If oil pressure doesn’t show on
the gauge within 30 seconds of starting, turn the key
to the off position and wait one minute; then repeat
the starting procedure.
Mercedes-Benz
CAUTION
Never attempt to start any Mercedes-Benz elec-
tronic engine using ether or any other starting
fluid. Serious engine damage could result.
The intake air preheater is activated by turning the
ignition switch to the on position. See Fig. 7.7.Ifthe
engine is at normal temperature, the INTAKE
HEATER indicator goes out after two seconds.
If the temperature is low enough to require the
heater, the INTAKE HEATER indicator stays on while
the intake air preheater warms up. After the indicator
goes out, start the engine. If the engine doesn’t start
after about 30 seconds of cranking, turn the key to
the off position and wait two minutes; then repeat the
starting procedure.
NOTE: If the engine doesn’t start on the second
try, wait at least five minutes before using the
intake air preheater again.
Starting After Extended
Shutdown or Oil Change—CAT,
Cummins, DDE S60, M-B
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 ad-
equate bearing protection at start-up. For this reason,
change the engine 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.
