18. WELD OUTPUT TER AND -
These 1/2” - 13 studs with flange nuts provide welding
connection points for the electrode and work cables. For
positive polarity welding the electrode cable connects to
the “+” terminal and the work cable connects to this “-” ter-
minal. For negative polarity welding the work cable con-
nects to the “+” terminal and the electrode cable connects
to this “-” terminal.
AUXILIARY POWER CONTROLS
(Items 19-23)
19. 120/240 VAC SINGLE PHASE RECEPTACLE
This is a 120/240VAC (14-50R) receptacle that provides
240VAC or can be split for 120VAC single phase auxiliary
power. This receptacle has a 50 amp rating. Refer to the
AUXILIARY POWER RECEPTACLES section in the
installation chapter for further information about this recep-
tacle. Also refer to the AUXILIARY POWER OPERATION
section later in this chapter.
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 ground
fault circuit interruption protection provide 120VAC
single phase for auxiliary power. Each receptacle
has a 20 amp total rating. They are designed to pro-
tect the user from the hazards of ground faults.
When the GFCI has tripped there will be no voltage
available from the receptacle. If the GFCI has
tripped, any device plugged into the GFCI recepta-
cle should be unplugged and the reason for tripping
the GFCI should be determined. If the device is
found to be damaged or defective, it should be
repaired or replaced before any further use. The
GFCI should be checked for proper operation prior
to each use by pressing the test button. The GFCI
can be reset by pushing the reset button. Refer to
the AUXILIARY POWER RECEPTACLES section in
the installation chapter for further information about
these receptacles. Also refer to the AUXILIARY
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 recepta-
cle has a 50 amp rating.
ENGINE OPERATION
STARTING THE ENGINE
1. Open the engine compartment door and check that
the fuel shutoff valve located to the left of the fuel
filter housing is in the open position (lever to be in
line with the hose).
2. Check for proper oil level. Close engine compart-
ment door.
3. Remove all plugs connected to the AC power
receptacles.
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. After 10 seconds, the engine protection light
will turn off.
6. Within 30 seconds, press and hold the engine
START button until the engine starts.
7. Release the engine START button when the engine
starts.
8. Check that the engine protection and battery charg-
ing lights are off. The engine protection light is on
after starting, the engine will shutdown in a few sec-
onds. Investigate any indicated problem.
9. Allow the engine to warm up at low idle speed for
several minutes before applying a load and/or
switching to high idle. Allow a longer warm up time
in cold weather.
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.
