FOOT BRAKES PEDALS
Foot brakes are disc, wet, mechanically-
controlled and two-pedaled.
When going on the road, both pedals
must be connected with a flap.

B - Pedals with flap for trailer air brakes
When going on the road, both
pedals must be joined with a flap.
Disconnected pedals for braking
the right or left wheel to be used
only when working in terrain and
on the field.
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!
NOTIFICATION SIGNALIZATION OF
AIR PRESSURE DROP
Drop in pressure under 450 kPa is sig-
nalized by a red control lighting up on the
dashboard.
The tractor with a braked trailer
or semi trailer must not continue
in travel with pressure drop in air
pressure system below 450 kPa
(control light up), if air pressure
does not go up.
