Of The Shifting Lever When The Foot Brakes; Air Brakes Of Trailers And Semi-Trailers; During Normal Operation And Be-Warning Indication Of Air Pressure Drop - Zetor Proxima Plus Series Operator's Manual

FOOT BRAKES
The foot brakes are disk wet type, hy-
draulic-controlled, with two pedals and
automatic pressure balancer.
During travel both pedal have to
be coupled with a latch. Use un-
coupled pedals for barking of the
right or left wheel only when
working in terrain and on a field
at low travel speeds.
Note: When driving from a steep
downslope with a trailer or semi-trailer
equipped with air or hydraulic brakes it is
necessary to start braking by foot brake
already from beginning of the slope!
With braking by one brake pe-
dal the trailer brakes are not
activated!

AIR BRAKES OF TRAILERS AND
SEMI-TRAILERS
Air brakes of trailers (semi-trailers) and
brakes of the tractor are designed so that
braking effects of both vehicles are syn-
chronised.
When driving with a trailer or
semi-trailer the foot brake pedals
shall be coupled and secured by
a latch!
With braking by one brake pe-
dal the trailer air brakes are not
activated.
Note: In case of a drop of pressure the
transfer valve disables the secondary
consumers (differential lock, disengage-
ment of the front driving axle).
