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, genera-
tor 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 Start button if the engine fails to start in
20 seconds, wait 30 seconds and repeat the
above procedure.
4. 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”.
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. 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.
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 starting
fluids be used!
------------------------------------------------------------------------
With a fully charged battery and the proper oil, the
engine should start satisfactorily down to 14°F(-10°C).
If the engine must be frequently started at or below
14°(-10°C), it may be desirable to install cold-starting
aides. The use of No. 1D diesel fuel is recommended
in place of No. 2D at temperatures below 14°F(-10°C).
Allow the engine to warm up before applying a load or
switching to high idle.
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 dis-
tribution system. If this happens, bleeding of the fuel
system may be necessary. Use qualified personnel to
do this per the instructions in the MAINTENANCE sec-
tion of this manual.
