DRIVING OPERATION
Driving down the slope
Foot brakes
Air brakes of trailers and articulated trailers
Warning signalization of air pressured drop
Driving down the slope without engaged gear
speed is forbidden. If you travel from a longer slope,
shift the lower gear speed the steeper the slope is.
Shift the lower gear speed before the slope, if
possible.
Note:
The gear speed with which you easily overcome an
ascent, you will also successfully manage descent.
F11N021
They are disc, wet, hydraulically controlled, double-
pedalled with automatic pressure equalizer.
When driving on the road, both pedals must be
connected by valve. Use disconnected pedals for
braking right or left wheel only when working in
terrain or on the field.
Note:
When going down a steep slope with a trailer or
articulated trailer equipped with air or hydraulic brakes, it
is necessary to brake by a foot brake from the beginning
of descend.
When braking with one brake pedal trailer´s
brakes are not active!
FHD14N086
Control of air brakes of trailers (or semi-trailers) and
control of the tractor brakes is performed so that the
braking effect of both vehicles is synchronized.
The operating pressure is set by the pressure regulator to
the value of 740 ± 20 kPa. If the pressure drops below 550
- 40 kPa, secondary appliances are put out of operation by
the by-pass valve.
F11N022
Air pressure drop below 450 kPa is signalized by alit red
control bulb placed on a dashboard.
Tractor with braked trailer or articulated trailer
with pressured drop in air pressure system under 450
kPa must not continue in transport if there is not
increase in air pressure.
