PRONAR T672ECO

mode is done manually by the machine
operator before starting the journey using
the lever (4).
Three work positions are available: A - ‘No
load’, B - ‘Half load’ and C - ‘Full load’.
PNEUMATIC CONNECTIONS
Pneumatic connections are equipped with
covers (2), protecting them against dirt and
dust entering the system. They are made of
coloured plastic (black connector - supply
and control air of a 1-wire system, red
connector - supply air of a 2-wire system,
yellow connector - control air of a 2-wire
system). The connectors are made in ac-
cordance with the recommendations of
DIN ISO 1728, which makes it impossible
to mistakenly connect the connectors to
agricultural tractor sockets. After uncou-
pling the trailer, pneumatic connections
should be placed in sockets prepared for
this purpose, located on the drawbar.
