Draining condensate from the air reservoir
Checking the air systems for leaks
Working pressure of air brakes
When the air-conditioning functions properly, water
condenses in the roof space of the cab and the
condensate is drained through hoses in the cab pillars and
runs out at the bottom side of the pillar. This is why you
must make sure that the condensate drain hoses will not
be blocked.

Draining is performed by deflecting or compressing the
protruding part of the valve.
The air reservoirs are located in front of the rear axle.
Th tractors are equipped with one air reservoir installed on
the left side of the tractor as standard or * two air
reservoirs positioned on the right and left side of the
tractor (if air-pressure brakes are in-stalled).

- fill the air reservoir to the maximum pressure (730 ± 20
kPa).
- 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 semi-trailer. In case of a brake system
failure or if the pressure drops below 450 ± 30 kPa, the
warning indicator on the dashboard will light up.
C15N131
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).
