CHECKING THE AIR SYSTEMS FOR LEAKS −Fill the air reservoir to the maximum pressure −With the engine stopped the air pressure must not drop by more than 10 kPa in 10 minutes. Perform the leak check daily before driving with a trailer or semitrailer. In case of a brake system failure or if the pressure drops below 450 kPa, the warning indicator on the dashboard will light up.
WORKING PRESSURE OF AIR BRAKES In the single- and double-hose version the air pressure at the double-hose coupling (2) (red cap) is 740 ± 20 kPa and at the single-hose coupling (1) max. 600 ± 20 kPa (at the moment the pressure controller relieves the compressor - blows out the air).
