MAINTENANCE INSTRUCTIONS

Draining condensate from the air reservoir

Draining is performed by deflecting or compressing the
protruding part of the valve. The air reservoirs are located
in front of the rear axle. The 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).

Checking the air systems for leaks

- 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.

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).
