Improper jump start cable connections can cause
an explosion resulting in personal injury.
Prevent sparks near the batteries. Sparks could
cause vapors to explode. Do not allow jump start
cable ends to contact each other or the engine.
Note:
If possible, first diagnose the reason for the
starting failure. Refer to Troubleshooting, “Engine
Will Not Crank and Engine Cranks But Will Not Start”
for further information. Make any necessary repairs.
If the engine will not start only due to the condition of
the battery, either charge the battery, or start the
engine by using another battery with jump-start
cables. The condition of the battery can be
rechecked after the engine has been switched OFF.
NOTICE
Never attempt to start an engine from an external
power source such as electric welding equipment,
which has a voltage that is unsuitable for engine
starting and will damage the electrical system.
For 904D-E28T industrial engines, use a 12 VDC bat-
tery source to start the engine.
For 904D-E36TA industrial engines, ensure that a 12
VDC or 24 VDC battery source is used to start the
engine.
NOTICE
Using a battery source with the same voltage as the
electric starting motor. Use ONLY equal voltage for
jump starting. The use of higher voltage will damage
the electrical system.
Do not reverse the battery cables. The alternator can
be damaged. Attach ground cable last and remove
first.
Turn all electrical accessories OFF before attaching
the jump start cables.
Ensure that the main power switch is in the OFF posi-
tion before attaching the jump start cables to the en-
gine being started.
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
will
be
held
at
low
speed.
The
time
held
at
low
speed
will
depend
on
ambient
temperature
and
time
since
last
run.
The
procedure
is
to
allow
the
engine
systems
to
stabilize.
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.
• 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.
