ENGINE OPERATION

CAUTION

Do not adjust the high idle engine speed (rpm) above the factory setting specification as this will overspeed the air compressor and void it’s warranty.

------------------------------------------------------------------------

STARTING INSTRUCTIONS

Be sure all Pre-Operation Maintenance has been per- formed. (See INSTALLATION section of this manual). Set the air compressor “ON/OFF” switch in the “OFF” position. To start the engine, place ignition toggle switch in the “ON” position. Engage the starter button. When the engine starts running, observe the engine oil pressure. If no pressure shows within 30 seconds, stop the engine and consult the engine operating man- ual. To stop the engine, place the ignition toggle switch in the “OFF” position.

When an engine is started for the first time, some of the oil will be needed to fill the passages of the lubri- cating system. Therefore, on initial starting, run the engine for about five minutes and then stop the engine and recheck the oil. If the level is down, fill to the full mark again. The engine controls were properly set at the factory and should require no adjusting when received.

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 or compressor overheating.

COLD WEATHER STARTING

WARNING

Never use any other starting aids, such as ether, when using the “Thermostart” system.

------------------------------------------------------------------------

When overnight temperatures are between 10°F (- 12°C) and freezing, use the standard “Thermostart” starting system installed on all engines. Follow the instructions on the start panel nameplate and in the engine manual shipped with the welder. With fully charged batteries and the proper weight oil, the “Thermostart” system operates satisfactorily even down to about 0°F (-18°C).

AIR COMPRESSOR (SAE400 WELD’N AIR only)

Cylinder head stud torque must be checked after initial 8 to 10 hours of operation. See compressor operator’s manual for details. Compressor mounting bolts should be checked for tightness after initial 8 to 10 hours of operation.
