Since the vehicle system is homologated according to European Code standards, it is mandatory to periodically check the efficiency
of system and related components with device 99305117.
These checks must be carried out with unmoving vehicle, using the compressed air into the tanks, recharged, with started-up
engine, by the compressor.
!
Always lock the vehicle, before any intervention. Periodically check the manometers by comparing them with a sample
manometer.

DEVICE
DENOMINATION
INTERVENTIONS
Compressor
Check of fittings tightening and compressor securing; make sure that
cooling fins are not dirty.
A.P.U. (Air Processing Unit)
Check by actuating a drain valve or by loosening a screw plug (with
integrated drain hole), whether the air drier correctly operates. In
this case air must go out of the tank without traces of condensate
water.
Air tanks
Humid
Front axle
Rear axle
Trailer + parking
Check of corrosion-preventing seal and protection.
Discharge the condensate from tanks by operating on the drain
valve.
Duplex distributor
Completely press the pedal; when the action ceases, the pedal must
immediately go back into its rest position.
Pressure limiting: 7.6
± 0.3 bar.
Check that the pedal gasket is not worn, that brake control tie-rods
are well tightened and lubricated, nor distorted. Check that lever
housings are neither worn nor oxidised.
Pressure relief valve
Check calibration pressure (see Characteristics and data table).
Check its functionality.
Relay valve
Check functionality and seal evaluating brake cylinders quick
intervention.
Engine brake control
operating cylinder
Check functionality and seal.
