DRIVING OPERATION
E224 G225 G226
FOOT BRAKES
The foot brakes are of the disc, wet, hy-
draulically controlled, double-pedal type
with an automatic pressure compensator.
During driving both the pedals must
be connected with a latch. Only
use unlatched pedals for braking
the right or left wheel separately
during terrain work and in the field
at low travelling speeds.
Note: When driving down a steep slope
with a trailer or semi-trailer equipped with
air or hydraulic brakes you must use the
foot brake from the beginning of the
slope already.
During braking with one brake
pedal the trailer brakes are not
in operation!
AIR BRAKES OF TRAILERS AND
SEMI-TRAILERS
The control of the air brakes of trailers
(semi-trailers) and the control of the trac-
tor brakes is designed in such a way that
the braking effect of both the vehicles is
synchronized.
During driving with a connected
trailer or semi-trailer the pedals of
the foot brakes must be con-
nected and secured with a latch.
During braking with one brake
pedal the air brakes of the
trailer are not in operation.
Note: In case of a pressure drop the re-
lief valve puts all the secondary devices
(differential lock, disengagement of the
front driving axle) out of operation.
WARNING INDICATION OF AN AIR
PRESSURE DROP
A pressure drop below 450 kPa is sig-
nalled by the illumination of the red indi-
cator and red TRACTOR symbol with the
STOP inscription on the dashboard.
In case of a pressure drop below
450 kPa in the air pressure sys-
tem a tractor with a braked trailer
or semi-trailer must not continue
travelling until the air pressure in-
creases again.
