ENGINE OPERATION

WARNING

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.

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 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:

WARNING

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.
