WARNING
If you drive off with the tipper body raised, it
could get caught on buildings, bridges or
trees, for example. There is a risk of an acci-
dent.
Before pulling away, always ensure that the
tipper body is lowered and properly secured.
!
Different types of hydraulic fluid are rarely
compatible although they are mixed from the
same oil base. Mixing hydraulic fluid types
always affects their characteristics, perform-
ance and reactions. You must not mix the
semi-trailer hydraulic system's hydraulic
fluid. The hydraulic fluid for the trailer hydrau-
lic system must therefore match the hydraulic
fluid for the semi-trailer hydraulic system.
Otherwise, it can result in damage to the
semi-trailer hydraulic system.
!
Observe the following instructions for oper-
ating the semi-trailer hydraulic system:
R
the semi-trailer hydraulic system's operat-
ing pressure must not exceed the maxi-
mum permitted operating pressure for the
trailer hydraulic system
R
the tipper semi-trailer's hydraulic lines
must be connected
R
the low-speed splitter group must be acti-
vated
Otherwise, the semi-trailer hydraulic system
and/or the trailer hydraulic system may be
damaged.
General notes
If using the semi-trailer hydraulic system, you
many only operate tipper semi-trailers with a
one or two line system. You operate their
hydraulic system with a pick-up valve in the driv-
er's cab. The semi-trailer hydraulic system's
operating pressure is switchable between
170 bar (low pressure) and 250 bar (high pres-
sure).
The hydraulic line connections have screw cou-
plings of either 1 inch or DN 20.
The semi-trailer hydraulic system is filled at the
factory with a hydraulic fluid from HLP (HLP-D
Before operating a tipper semi-trailer, be sure
that:
R
the semi-trailer hydraulic system's operating
pressure does not exceed the maximum per-
mitted operating pressure for the trailer
hydraulic system
R
the hydraulic connections of both hydraulic
systems are compatible
R
the trailer hydraulic system's hydraulic fluid
matches that of the semi-trailer hydraulic sys-
