SECTION 5 - OPERATION Operating & Maintenance Manual
45
Close air service valves.
• Allow the unit to run at idle for 3 to 5
minutes to reduce the engine
temperatures.
• Turn Power Switch to “OFF” position.
• When the engine stops, automatic
blowdown valve should relieve
system air pressure. If automatic
blow-down valve malfunction is
suspected, open manual blowdown
valve.
• 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 disconnect
hoses until all pressure has been
vented.
NOTICE
Do NOT wire around or
bypass a shutdown sensor
or switch.
Machine has shutdown and sensors
as follows:
• Low Engine oil pressure, in the
engine.
• High engine coolant temperature, in
the engine.
Compressor Air/Oil Temperature:
• At the airend outlet.
• In separator tank.
UNITS WITH DIAGNOSTIC LAMPS
In a shutdown situation, the function of the
panel lamps is to indicate what specific
failure caused the unit to shut down. These
lamps will remain illuminated until the Power
Switch is turned “OFF”.
