Hydraulic connections
Connecting or disconnecting hydraulic
lines
Keep the hydraulic lines such that they can man-
age all movements when cornering etc. without
tensioning, kinking or rubbing. Before connect-
ing the hydraulic lines be sure that their screw
couplings are compatible with the sockets on
the towing vehicle. Do not use any tools when
connecting the hydraulic lines and do not climb
on any part of the vehicle.
Before coupling and decoupling the hydraulic
lines, the semi-trailer hydraulic system must be
depressurised and the trailer's tipper body
should be fully lowered. The semi-trailer hydrau-
lic system is only depressurised if the control
lever in the driver's cab is in the centre position
(STOP) and power take-off is disengaged. A few
drops of hydraulic fluid may escape when sep-
arating the hydraulic connections. Observe the
national work safety and accident prevention
regulations as well as the environmental pro-
tection regulations.
If the tipper semi-trailer is fitted with a two-line
system, connect the pressure line to connec-
tion
;
and the return flow line to connec-
tion
:
. If the return flow line is not coupled or
coupled incorrectly, it can result in damage to
the tipper semi-trailer's hydraulic system.
If the tipper semi-trailer is fitted with a one-line
system, connect the hydraulic line to connec-
tion
;
on your vehicle. Connection
:
for the
return line remains free in this case.
