NOTICE Damage due to incorrect oil pressure setting
Incorrect oil pressure setting can result in severe dam-
age to property and the environment.
u Before installing the hydraulic attachment to the car-
rier check the oil pressure setting of pressure line
»P« with a hydraulic flow tester.
u Check the tank/return line pressure with an additional
manometer mounted between hydraulic flow tester
and tank line »T«.
u Ensure the technical specifications are fulfilled (see
chapter Technical specifications).
5.4.3 Install separate leakage oil line
The separate leakage oil line including separate leakage
oil filter must be installed from the shut-off valve on the
boom to the carrier's hydraulic oil tank. The operator
must pre-install a suitable connection on the carrier's hy-
draulic oil tank for the leakage oil line.
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).

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.
5.4.4 Making the hydraulic connections
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 by releasing the
carrier's hydraulic tank pressure.
n
Close all shut-off valves in the installation at the
boom, if no quick couplings are used.
NOTICE Damage to hydraulic parts
Polluted hydraulic lines and connections may enable
sand, fragments of material and dirt to penetrate the hy-
draulic attachment and damage the hydraulic parts.
u Clean the hydraulic lines and connections prior to
connecting the hydraulic lines.
n
Have dirty hydraulic lines rinsed through by a special-
ist company.
n
Clean dirty hydraulic line connections with a suitable
grease-dissolving universal cleaner.
n
Observe the cleaner manufacturer's information on
safety and use.
n
Connect the hoses of the pressure line »P«, the tank
line »T« and the hose for the function »magnet plate
on/off« at the boom.
n
Remove the screw caps from the connections »A«,
»F« and »G« of the Hydro Magnet and keep them in
a safe place.
