pressure.
1 3/4 in NPT Air Pressure
Fitting
2 Air 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.
