Units With Optional Diagnostics
Lamps
NOTICE
None of the panel lamps should be
glowing when machine is operating. If
they are, shut unit down and refer to
Trouble Shooting Section.
Stopping
Close air service valve.
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.
Automatic Shutdown
This unit is protected with sensors (switches)
for high discharge air temperature, high
engine coolant temperature and low engine
oil pressure.
Should any of three situations occur, the unit
will stop. Before restarting the unit, check
these three areas for excessive heat and
fluid level. Other possible causes are listed
on the Trouble Shooting Chart.
All units in this family of machines are
protected by sensors or switches at the
following locations:
1. Low engine oil pressure, in the engine.
2. High engine coolant temperature, in the
engine.
High Discharge AIR Temperature
3. At the airend outlet.
4. In separator tank.
NOTICE
Do NOT wire around or bypass a
shutdown sensor or switch.
DANGER !
Even after pressure is relieved from
the receiver-separator system, any air
supply line from the compressor to a
tool or a machine could remain under
pressure and cause very serious
personal injury or death. After the
compressor stops, carefully open a
valve at any tool or machine to
exhaust the pressure in any line prior
to removal or servicing.
