ENGINE OPERATION
For added safety always operate the welder with the
doors closed. Further, leaving the doors open
changes the designed air flow and may cause engine,
generator overheating.
Do not adjust the high idle engine speed (rpm)
above the factory setting specification as this will
void warranty.
------------------------------------------------------------------------
STARTING INSTRUCTIONS
Be sure all Pre-Operation Maintenance has been
performed. (See INSTALLATION section of this
manual).
1. Press the “IDLER” switch to “RUN”.
2. Push (For 2 Seconds) & release the “START” but-
ton to start the engine. This switch has an amber
light to indicate glow. This engine will automatically
apply power to the glow circuit & indicator light will
turn off when is complete. This switch also has a
red light (Bottom of Switch) that will light up when
there are faults with the engine (Check engine light
comes on). Field Service shop will need to connect
to diagnostic plug to read detailed error codes.
General fault code numbers are displayed on dash
board gauge.
CAUTION
Do not attempt to use this equipment until you have
thoroughly read the engine manufacturer’s manual
supplied with your welder. It includes important
safety precautions, detailed engine starting, operat-
ing and maintenance instructions, and parts lists.
------------------------------------------------------------------------
ELECTRIC SHOCK can kill.
• Do not touch electrically live parts or
electrode with skin or wet clothing.
• Insulate yourself from work and
ground
• Always wear dry insulating gloves.
------------------------------------------------------------------------
ENGINE EXHAUST can kill.
• Use in open, well ventilated areas or
vent exhaust outside.
------------------------------------------------------------------------
MOVING PARTS can injure.
• Do not operate with doors open or
guards off.
• Stop engine before servicing.
• Keep away from moving parts.
------------------------------------------------------------------------
See additional warning information at the
front of this operator’s manual.
WARNING
3. If the engine fails to start in 60 seconds, wait 30
seconds and repeat the above procedure. Do not
allow the starter motor to run continuously for
more then 20 seconds.
4. Observe the oil pressure. If no pressure shows
within 20 seconds, stop the engine and consult
the engine operating manual. To stop the engine,
turn the “IDLER” switch to “STOP”.
5. If the engine protection warning light comes on
during cranking or after start up, the “IDLER”
switch must be turned “STOP” to reset the engine
protection system.
6. Allow the engine to run at high idle speed for sev-
eral minutes to warm the engine. Stop the engine
and recheck the oil level, after allowing sufficient
time for the oil to drain into the pan. If the level is
down, fill it to the full mark again. The engine con-
trols were properly set at the factory and should
require no adjusting when received.
COLD WEATHER STARTING:
Under NO conditions should ether or other start-
ing fluids be used!
------------------------------------------------------------------------
With a fully charged battery and the proper weight oil,
the engine should start satisfactorily even down to
about -15°F (-26°C), it maybe desirable to install cold-
starting aides.
Note: Extreme cold weather staring may require
longer glow plug operation.
STOPPING THE ENGINE
1.
Important:
Run the engine under low idle for 5 minutes
before shutting it off after a full load operation.
Note:
Failure to do so may lead to turbo charger
trouble.
2. Turn the “IDLER” switch to “STOP”
At the end of each day’s welding, check the crankcase
oil level, drain accumulated dirt and water from the
water separator and refill the fuel tank to minimize
moisture condensation in the tank. Also, running out
of fuel tends to draw dirt into the fuel system.
When hauling the welder between job sites, close the
fuel shut-off valve.
If the fuel supply is cut off or runs out while the fuel
pump is operating, air may be entrapped in the fuel
distribution system. If this happens, bleeding of the
fuel system may be necessary. Use qualified person-
