ATTENTION: AS PRESSURE IN THE TANK GOES UP TO 0.77 MPA, THE COM-
PRESSOR IS SWITCHED TO IDLE RUNNING BY THE PRESSURE REGULATOR AND
TYRE INFLATION STOPS AUTOMATICALLY. FOR THIS REASON, CHECK THE PRES-
SURE OVER THE INDICATOR ON THE DASHBOARD FROM TIME TO TIME AND, IF
NECESSARY, REDUCE IT THROUGH THE CONDENSATE REMOVING VALVE!

- detach the hose from the tyre valve and from the air bleed fitting;
- turn off the pneumatic compressor 1 and screw in the winged nut or install cap 2
onto fitting 3 of the tyre inflation valve 4.
