Engine Starting
This engine chapter is to serve as a guide for best
practices only. Each engine model may have operat-
ing characteristics that are unique to that particular
engine, and will be documented in the engine manu-
facturer’s literature. Always refer to specific instruc-
tions and recommendations from the engine manu-
facturer.
NOTE: Before starting the engine, read Chap-
ter 4 , Instruments , and Chapter 5 , Driver
Controls . Read the engine manufacturer’s oper-
ating instructions before starting the engine.
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
damage.
IMPORTANT: The starter can not be used for
priming the fuel system. If the fuel/water separa-
tor filter is replaced, and the fuel system needs
to be primed, see the engine manufacturer’s
operating instructions.
1. Before engine start-up, complete the pre- and
post-trip inspections and maintenance proce-
dures in
Chapter 23 .
2. Set the parking brake.
3. Place the transmission in neutral. On vehicles
with manual transmissions, fully depress the
clutch pedal.
NOTE: Depending on local jurisdictional emis-
sions regulations, vehicles may not be equipped
with the WAIT TO START lamp.
4. Turn the ignition switch to the ON position and
allow the gauge sweep to complete. See
Fig. 9.1 . The audible alert will sound for approxi-
mately four seconds.
During cold conditions, the WAIT TO START
lamp may illuminate. Wait until the lamp goes out
before turning the ignition switch to START.
NOTE: The length of time the WAIT TO START
lamp remains illuminated depends on the ambi-
ent temperature. The lower the ambient tem-
perature, the longer the lamp will be illuminated.
5. Once the gauge sweep has completed, turn the
ignition key to the START position. Release the
key the moment the engine starts.
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 10 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
pressure or mechanical malfunction in the lubri-
cating oil system. Minimum oil pressure at idle is
7 psi (48 kPa).
