Trailer and semi-trailer air brakes

Trailer (semi-trailer) air brakes control and tractor brakes
control is done in such a way that the braking effect of
both vehicles is synchronized.
When travelling with a connected trailer or
semi-trailer foot brake pedals must be connected and
secured with a flap! When braking with a single brake
pedal, air brakes of a trailer are not in operation.
Note: When travelling down a steep slope with a trailer or
semi trailer equipped with air brakes, it is necessary to
brake with a foot brake before the descent starts!
During connection of the hoses of air brakes of trailers and semi-trailers the lever of the hand
brake must be pulled.
Notification signalization of air pressure drop
If the air pressure in the air brake system falls under
a critical limit, a red indicator on the dash board comes on.
In case the pressure in the air-pressure system
drops under a critical limit (the indicator comes on),
the tractor with a braked trailer or semitrailer is not
allowed to continue operation until the air pressure
increases.
