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. Turn the “IDLER” switch to “HIGH”.
2. Turn the “IGNITION” switch to “ON”.
3. Press the Glow Plug button for 20 to 30 seconds.
(maximum 60 seconds).
4. Press the Glow Plug and the Start button at the
same time. When the engine starts running,
release both buttons. If the engine fails to start in
20 seconds, wait 30 seconds and repeat the
above procedure.
Do not attempt to use this equipment until you
have thoroughly read the engine manufacturerʼs
manual supplied with your welder. It includes
important safety precautions, detailed engine
starting, operating 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 operatorʼs manual.
WARNING
5. Observe the oil pressure. If no pressure shows
within 30 seconds, stop the engine and consult
the engine operating manual. To stop the engine,
turn the “IGNITION” switch to “OFF”.
6. If the engine protection warning light comes on
during cranking or after start up, the “IGNITION”
switch must be turned “OFF” to reset the engine
protection system.
7. 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 -5°F (-20°C), it maybe desirable to install cold-
starting aides.
Note: Extreme cold weather staring may require
longer glow plug operation.
STOPPING THE ENGINE
1. Turn the “IGNITION” switch to “OFF”
At the end of each dayʼs 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-
nel to do this per the instructions in the MAINTE-
NANCE section of this manual.
