Engine Starting

General Information
This engine chapter is to serve as a guide for best
practices only. Each make and model engine may
have operating characteristics that are unique to that
particular engine, and will be documented in the en-
gine manufacturer's literature. Always refer to specific
instructions and recommendations from the engine
manufacturer.
NOTE: Before starting the engine, read
ter 2 and Chapter 3
information on how to read the instruments and
operate the controls.

Normal Starting

WARNING
Do not use any starting aid, such as ether, in en-
gines with an air intake heater. This could cause
an explosion and serious personal injury or
death.
NOTE: Cummins engines are run on a dyna-
mometer before being shipped from the factory.
They do not require a break-in period.
IMPORTANT: Special break-in oils are not rec-
ommended for new or rebuilt Cummins engines.
NOTICE
If a vehicle does not start on the first attempt,
make sure that the engine has completely
stopped rotating before reapplying the starter
switch. Failure to do so can cause the pinion to
release and re-engage, which could cause ring
gear and starter pinion damage.
Moving a vehicle with the starter and/or using the
starter to bump the engine for maintenance pro-
cedures is strictly prohibited. Use of these meth-
ods to bump the engine over or move the vehicle
can cause the pinion to release and re-engage,
which could cause ring gear and starter pinion
damage.
IMPORTANT: Ring gear and starter pinion dam-
age caused by improper starting procedures is
not warrantable.

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.
NOTICE
If the engine is equipped with a turbocharger,
protect the turbocharger during start-up by not
depressing the accelerator pedal until normal en-
gine idle oil pressure registers on the gauge.
1. Before engine start-up, complete the pre- and
post-trip inspections and maintenance proce-
dures in Chapter 10.
2.
Set the parking brake.
3. Place the transmission in neutral.
4. Turn the key to the ON position and allow the
gauge sweep to complete. The audible alert will
sound for approximately four seconds.
During cold conditions, the WAIT TO START
lamp may illuminate. Wait until the lamp goes out
before turning the key to START.
5. After the gauge sweep has completed, turn the
key to the START position.
NOTICE
Do not rev the engine if the oil pressure gauge
indicates no oil pressure. Shut down the engine
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.
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.
7. 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).
