NOTICE
Ensure that a 12 VDC or 24 VDC battery source is
used to start the engine. Never attempt to start an en-
gine from an external power source such as electric
welding equipment, which has a voltage that is un-
suitable for engine starting and will damage the elec-
trical system.
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.
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
Note:
In
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),
extra
warm-up
time
may
be
required.
When
the
engine
idles
during
warm-up,
observe
the
following
conditions:
• 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
action may not be possible in some applications.
• Operate the engine at low idle until all systems
achieve operating temperatures. 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.
