ENGINE OPERATION
WARNING
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, 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 operator's
manual.
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.
CAUTION
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.
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 several 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
controls were properly set at the factory and should require no
adjusting when received.
WARNING

COLD WEATHER STARTING:

Under NO conditions should ether or other starting 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 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 personnel to do this per the instructions in the
MAINTENANCE section of this manual.
