NOTICE
None of the panel lamps should be glowing when ma-
chine is operating. If they are, shut unit down and refer
to Trouble Shooting Section.
STOPPING
1. Close air service valve.
2. Allow the unit to run at idle for 3 to 5 minutes to
reduce the engine temperatures.
3. Turn Power Switch to “OFF” position.
4. When the engine stops, automatic blowdown
valve should relieve system air pressure. If
automatic blowdown valve malfunction is
suspected, open manual blowdown valve.
5. Never allow unit to sit under pressure when
engine is not running.
WARNING
Since the service valve is closed, air downstream of
the valve may be trapped. A vent hole in the service
valve will slowly bleed air from the hose. Do not discon-
nect hoses until all pressure has been vented.

Do NOT wire around or bypass a shutdown sensor or
switch.
