! Air pressure is present at air shutoff valve whenever Air Pressure Gauge on front panel indicates air pressure.

13/4 in NPT Air Pressure Fitting

2Air Shutoff Valve

Connect air hose with 3/4 in NPT fitting (not supplied) to air shutoff valve.

Be sure valve is in open position when us- ing air compressor.

The compressor runs and air pressure is available whenever the engine is running and the front panel Compressor switch is moved to the On position (see Section 6-1).

Run engine at weld/power speed for maxi- mum air compressor output. Compressor output is reduced when engine is running at idle speed.

The air compressor will not start if still under pressure. If air compressor is turned off, wait for air pressure to bleed off (about 20 seconds) before turning air compressor on again.

.Using the air compressor does not sig-

nificantly affect weld or generator pow- er output.
