Engine Starting
3. Connect one neg
ative end of the jump start cable
to the negative cable terminal of the electrical
source. Connect the other negative end of the
jump start cab
le to the engine block or to the
chassis ground. This procedure helps to prevent
potential sparks from igniting the combustible
gases that ar
e produced by some batteries.
Note: The engine ECM must be powered before the
starting mo
tor is operated or damage can occur.
4. Start the engine in the normal operating procedure.
Refer to thi
s Operation and Maintenance Manual,
“Starting the Engine”.
5. Immediate
ly after the engine is started, disconnect
the jump start cables in reverse order.
After jump
starting, the alternator may not be able to
fully recharge batteries that are severely discharged.
The batteries must be replaced or charged to the
proper vo
ltage with a battery charger after the engine
is stopped. Many batteries which are considered
unusable are still rechargeable. Refer to Operation
and Maint
enance Manual, “Battery - Replace” and
Testing and Adjusting Manual, “Battery - Test”.

After Starting Eng ine
Note: In ambie
nt temperatures from 0 to 60°C
(32 to 140°F), the warm-up time is approximately
three minutes. In temperatures below 0°C (32°F),
additional w
arm-up time may be required.
When the engine idles during warm-up, observe the
following c
onditions:
Do not check the high pressure fuel lines w ith the
engine or t
he starting motor in operation. If you
inspect the engine in operation, always use the
proper inspection procedure in order to avoid a
fluid penet
ration hazard. Refer to Operation and
Maintenance Manual, “General hazard Information”.
•
Check for
any fluid or for any air leaks at idle rpm
and at one-half full rpm (no load on the engine)
before operating the engine under load. This is not
possible
in some applications.
•
Allow the engine to idle for three to five minutes, or
allow th
e engine to idle until the water temperature
indicator begins to rise. Check all gauges during
the warm-up period.
Note: Gauge readings should be observed and
the data should be recorded frequently while the
engine
is operating. Comparing the data over time
will help to determine normal readings for each
gauge. Comparing data over time will also help
detec
t abnormal operating developments. Significant
changes in the readings should be investigated.
