20. CIRCUIT BREAKERS
These circuit breakers provide separate overload
current protection for each 120V circuit at the 240V
single phase receptacle, each 120V single phase
receptacle, the 240V three phase receptacle, the
120VAC in the 14-Pin connector, the 42VAC in the
14-Pin connector and battery circuit overload protec-
tion.
21. 120VAC SINGLE PHASE RECEPTACLES
These two 120VAC (5-20R) receptacles with GFCI
protection provide 120VAC single phase for auxiliary
power. Each receptacle has a 20 amp total rating.
They are designed to protect the user from the haz-
ards of ground faults. When the GFCI has tripped
there will be no voltage available from the receptacle.
Refer to the AUXILIARY POWER RECEPTACLES
section in the installation chapter for further informa-
tion about these receptacles. Also refer to the AUX-
ILIARY POWER OPERATION section later in this
chapter.
22. GROUND STUD
Provides a connection point for connecting the
machine case to earth ground. Refer to "MACHINE
GROUNDING" in the Installation chapter for proper
machine grounding information.
23. 240VAC THREE PHASE RECEPTACLE
This is a 240VAC (15-50R) receptacle that provides
240VAC three phase auxiliary power. This receptacle
has a 50 amp rating.

ENGINE OPERATION

STARTING THE ENGINE

1. Open the engine compartment door and check that
the fuel shutoff valve is in the open position (lever to
be in line with the hose).
2. Check for proper oil level and coolant level. Close
engine compartment door.
3. Remove all plugs connected to the AC power recep-
tacles.
4. Set IDLER switch to "AUTO".
5. Set the RUN/STOP switch to "RUN". Observe that
the engine protection and battery charging lights are
on. The engine protection light may turn off after 5
seconds or remain on until the engine is started.
6. Within 30 seconds, press and hold the engine
START button until the engine starts. If the engine
does not start within 30 seconds the RUN/STOP
switch must be returned to the STOP position, then
return to step 5.
OPERATION
7. Release the engine START button when the engine
starts.
8. Check that the engine protection and battery charg-
ing lights are off. Investigate any indicated problem.
NOTE: The engine will go through a 3 minute warm-up
cycle if cold. If the engine coolant is still warm
from recent operation, the engine will go imme-
diately to high idle and then to low idle if the idle
switch is in the "AUTO" position.
COLD WEATHER STARTING
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about 0°F(-18°C). If the engine must be frequently
started below 10°(-12°C), it may be desirable to install
the optional ether start kit (K887-1). Installation and
operating instructions are included in the kits.

STOPPING THE ENGINE

1. Switch the RUN/STOP switch to "STOP". This turns
off the voltage supplied to the shutdown solenoid. A
backup shutdown can be accomplished by shutting
off the fuel valve located on the fuel line.
