AIR PRESSURE BRAKES FOR TRAILER,
(24)
4
fitting instruction
GENERAL (fig. 1):
Instructions for operating:
--- On the two hose system the trailer is connected to
two different couplings (9--11), which have been
marked as follows:
--- C o nt a i n e r li n e --- red cover
--- B r ak e l in e --- yellow cover
On one hose system the trailer is connected to the
coupling with black cover (brake line) (is used on
some marketing areas).
The couplings of the Duo---Matic system have no
colour code, because these couplings cannot be
confused.
--- From air pressure system it is also possible to get
press for external purpose (8 bar), e.g. for tyre/tire
filling, from the coupling (fig. 1, ref 3) which is situ-
ated on the right side under the cab. Through this
coupling the system can be filled, when needed,
by outside compressed air e.g. when the com-
pressor of the tractor is broken. By doing this the
coupling can not be turned to bottom.
--- When the couplings (1) of the trailer are not in use,
keep the shields on them.
--- When the a mbient temperature is colder than
+5°C, in t he antifreeze container (3) must be filled
with ethyl alcohol or methanol. The liquid stream-
ing valve lever (4) has to be open (position 1).
The container and s treaming valve lever are situ-
ated under the right cab corner in front of the cab.
The valve with the container can be inclined when
filling by loosening the wing screw of the holder.
CAUTION:Theremustbefullpressureintheair
pressure system, about 7-- 8 bar (pressure

panel), before you start driving a tractor which
has a trailer with air pressure brakes.
--- The pressure regulator (fig 1, ref 3) adjusts the sys -
tem pressure. The system pressure can, if necess-
ary, be adjusted w ith spring 11 adjusting screw.
