Condensate drainage cock
open.
Close the condensate drainage
cock.
Rilsan hose not inserted
correctlyinpressureswitch.
Insert the Rilsan hose correctly
insidethepressureswitch.
Reductionofefciency,frequent
start-up.Lowpressurevalues.
Excessivelyhighconsumption.
Decrease the demand of
compressedair.
Leaksfromjointsand/orpipes. Changegaskets.
