DRIVE OPERATIONS
F108 F_02_39 F_02_55
FRONT CARDAN BRAKE
Front cardan brake is assembled as a
standard.
While braking with a single brake
pedal, the propeller shaft brake is
out of operation.
TRAILER AND SEMI-TRAILER
PNEUMATIC BRAKES
Control of the pneumatic brakes of trail-
ers (semi-trailers) and that of tractor
brakes are synchronized as for the
braking effect.
The pressure governor sets up the air
pressure to 740 ± 20 kPa. In case the
pressure drops below 550 - 40 kPa, the
bypass valve puts the secondary appli-
ances (differential lock, shifting-in of the
front driving wheels, pneumatic raising of
the three-point hitch, torque multiplier,
P.T.O shaft) out of operation.
AIR PRESSURE DROP WARNING
SIGNAL
Any drop of the air pressure bellow 450
kPa is signaled with the red signal light
on the instrument dashboard switched
ON.
In case the air pressure in the
pneumatic system drops below
450 kPa, the tractor towing a
braked trailer or semi-trailer may
not continue the transport until
the air pressure increases.
