DURING OPERATION
• Check that the regulating valve is correctly
functioning, i.e. starts decreasing the engine speed
when reaching the working pressure.
• Check on abnormal noise.
• Check the alarm lamps.
AIR OUTLET PRESSURE
The air outlet pressure is set in the factory.
STOPPING PROCEDURE
1. Close the air outlet valves (AOV).
2. Run unloaded for 3 minutes.
3. Turn the start switch S1 counterclockwise (CCW)
to position 0.
4. Open the hood and switch the main switch at the
back of the control panel to “OFF”.
FAULT SITUATIONS AND PROTECTIVE
DEVICES
• A fault involving the engine, either oil pressure
(too low), coolant temperature (too high), will
always and immediately cause the engine to cut
out and the alarm lamp H1 will light up.
• When the air outlet temperature is too high the
alarm lamp H2 will light up. The alarm lamp will
stay on, until the compressor has been restarted
(start switch to position 3), or the contact is
turned off (start switch to position 0; also when,
due to cooling off, the thermocontact has closed
again (= memory function).
When the engine is running, the air
outlet valves (ball valves) must always be
in a fully opened or fully closed position.
The hood must be closed during
operation and may be opened for short
periods only.
Be aware not to touch hot parts when the
hood is open.
Modifying the set point above the
nominal working pressure can affect the
correct working of the unit and result in
failure. Only the Atlas Copco customer
center or an authorized distributor may
work on, or adjust the regulating valve!
Incorrect use/operation of the machine,
including modifying the working
pressure above the nominal pressure,
will void warranty.
Be aware not to touch hot parts when the
hood is open.

Do not open the air outlet valve when
machine is shut down. Remaining air
inside the vessel will automatically be
evacuated via a blow down valve!
If pressure is released from the vessel too
quickly, oil will start creating foam. This
foam could reach the oil separator
element resulting in oil carry over.
Failures caused by incorrectly shutting
down the compressor will not be covered
by warranty!
