Stopping
NOTICE
Whenever the machine is stopped, air will flow back into the compressor system
from devices or systems downstream of the machine unless the service valve is
closed. Install a check valve at the machine service valve to prevent reverse flow
in the event of an unexpected shutdown when the service valve is open.
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 switches as follows:
• Low Engine Oil Pressure
• High Engine Coolant Temperature
• High Airend Discharge Temperature
• High Separator Temperature
• Low Fuel Level (Optional)
