Original Instructions
NOTICE
Damage due to incorrect installed hydraulic
hoses
Incorrectly installed hydraulic hoses can result in severe
damage to property and the environment. The maximum
pressure of the leakage oil line is 10 bar.
u
Install hydraulic hoses such that they always pos-
sess sufficient play for turning and rotating motions
of the boom.
u
Always check the leakage oil line pressure when
mounting the hydraulic attachment to a carrier.
n
Install a separate leakage oil line along the hydraulic
hoses on the boom and secure with cable ties.
n
Install the separate leakage oil line (J) with leakage
oil filter (I) to the connection on the carrier's hydraulic
oil tank (K).
K
J
I
Follow the safety and operating instructions of the
carrier when connecting the leakage oil line to the hy-
draulic oil tank.
n
Attach the leakage oil line to the pre-installed connec-
tion on the hydraulic oil tank and tighten with the re-
quired tightening torque.
n
Install the leakage oil filter at an appropriate location
on the carrier.
5.5.4 Making the hydraulic connections
WARNING
Hydraulic hose flailing about
Pressurised hydraulic hoses will flail about when con-
necting fittings have come loose or have been loosened.
A hydraulic hose flailing about may cause serious in-
juries.
u
Depressurise the hydraulic system before discon-
necting a hydraulic hose (see chapter
Depressuris-
ing the hydraulic system
).
u
Tighten the hydraulic hose connection nuts with the
required tightening torque.
NOTICE
Faulty hydraulic installation
The carrier must have a suitable hydraulic installation to
operate the hydraulic attachment. Improperly installed
lines and incorrectly rated sizes may cause the oil to
heat up and the hydraulic attachment to be damaged.
u
Only use hydraulic lines of the rated sizes as in-
structed (see chapter
Technical Specifications
).
u
Check the rated size of the hydraulic lines on existing
hydraulic installations! All supply and return lines for
the hydraulic oil must have a sufficient inside diame-
ter and wall thickness.
u
Route all hydraulic hoses in a torsion-free manner.
n
Switch off the carrier.
n
Depressurise the hydraulic system according to the
manufacturer's safety and operating instructions for
the carrier.
n
Close all shut-off valves in the installation at the
boom, if no quick couplings are used.
NOTICE
Total damage to the hydraulic attachment
Polluted hydraulic lines and connections may enable
sand, fragments of material and dirt to penetrate the hy-
draulic attachment and damage it completely.
u
Clean the hydraulic lines and connections before
connecting the hydraulic hoses. Lay all hydraulic
hoses so that they are torsion-free.
n
Install the pressure and tank hoses.
n
Connect the pressure and tank hoses.
n
If no quick couplings are used, open the shut-off
valves in the installation at the boom.
n
Switch on the carrier.
