After Starting Engine
1. Turn the start switch on the stalled engine to the
OFF position. Turn off all the engines accessories.
2. Connect one positive end of the jump-start cable to
the positive cable terminal of the discharged
battery. Connect the other positive end of the
jump-start cable to the positive cable terminal of
the electrical source.
3. Connect one negative end of the jump-start cable
to the negative cable terminal of the electrical
source. Connect the other negative end of the
jump-start cable to the engine block or to the
chassis ground. This procedure helps to prevent
potential sparks from igniting the combustible
gases that are produced by some batteries.
Note: The engine ECM must be powered before the
starting motor is operated or damage can occur.
4. Start the engine in the normal operating
procedure. Refer to this Operation and
Maintenance Manual, "Starting the Engine".
5. Immediately after the engine is started, disconnect
the jump-start cables in reverse order.
After jump starting, the alternator may not be able to
recharge fully batteries that are severely discharged.
The batteries must be replaced or charged to the
proper voltage with a battery charger after the engine
is stopped. Many batteries which are considered
unusable are still rechargeable. Refer to Operation
and Maintenance Manual, "Battery - Replace" and
Testing and Adjusting Manual, "Battery - Test".
After Starting Engine
After starting, the engine may be held at low speed
for a duration between 1 and 25 seconds to allow
engine systems to stabilize. The duration will depend
on ambient temperature, time since last run and
other factors.
Note: In ambient temperatures from 0°C to 60°C
(32°F to 140°F), the warm-up time is approximately 3
minutes. In temperatures below 0°C (32°F),
additional warm-up time may be required.
When the engine idles during warm-up, observe the
following conditions:
Do not check the high-pressure fuel lines with the
engine or the starting motor in operation. If you
inspect the engine in operation, always use the
proper inspection procedure to avoid a fluid
penetration 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
check may not possible in some applications.
• Allow the engine to idle for 3 to 5 minutes, or allow
the engine to idle until the water temperature
indicator begins to rise. Check all gauges during
the warm-up period.
Constant speed engines should be allowed to
operate at low idle for 3 minutes before used at
operational speed. If the low idle option is not
available, then operate the engine at operational
speed with no load for 2 minutes.
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 detect
abnormal operating developments. Significant
changes in the readings should be investigated.
