22.7. Check of safety valve
Damage to the safety valve
could cause pressure to rise to
hazardous levels.
Never use the safety valve to
release the air pressure in the
air tank. This could damage the
safety valve. The valve is set to
the
maximum permitted
pressure by the manufacturer.
Never adjust a safety valve.
Venting compressed air poses
an injury hazard.
Wear safety glasses when
inspecting a safety valve.

Turn the screw on the safety valve several
rotations to the left until the safety valve
releases air.

Let the safety valve vent for only a few
seconds.

Turn the screw to the right until it seats, closing
the valve.

22.8. Compressor performance check

Turn off the compressor using the
STOP button.

Vent the air pressure in the air tank to
zero.

Turn on the compressor using the
START button.

Measure the time to fill the air tank
from 0 to 7 bar.

The measured value must be less than
the data provided in the “Technical
Data” table.
22.9. Check of non-return valve
operation
Compressed air line:
Check for the proper operation of all non-
return valves in the compressed air line and
the disconnection of pressure hoses from air
pumps.
One air pump must be running
at all times, while the others
may be shut off using the
current protection device in the
switchboard. No compressed
air may leak from the non-return
valves.
Air tank:
Check for proper operation of the non-return
valve on the air tank by disconnecting the
pressure hose from the valve.
Check the non-return valve
operation once the air tank has
come up to pressure and with
the
compressor off. No
compressed air may leak.
