WARNING
When you switch off the hydraulic system, a
residual pressure remains in the hydraulic
system. This may cause attached equipment
to move or continue to run. There is a risk of
an accident and injury.
After switching off the hydraulic system,
R
always secure the attached equipment by
closing the cutoff valve on the equipment.
Insert the transport lock.

DANGER
If hydraulic connections of the same colour
are connected at the front and rear simulta-
neously, all hydraulic connections will be
pressurised to the same pressure. The equip-
ment fitted can then be set, uncontrolled, in
motion. Persons in the area of danger can be
seriously or even fatally injured.
Make sure that only one piece of equipment at
a time is ever connected to hydraulic connec-
tions of the same colour.
The working hydraulics may be fitted with up
to eight hydraulic connections at the front
and up to four connections at the rear. The
hydraulic connections are integrated into the
front and rear bumpers. The hydraulic con-
nections are colour-coded.
Hydraulic connections 1 to 8 can be propor-
tionally controlled with the control lever. You
can connect attached equipment with a con-
stant flow rate either to hydraulic connec-
tion 1 or hydraulic connection 3; switching
continuous consumers on/off (
