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 3 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 drum cutter 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.
5.4.3 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 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 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.
NOTICE Property damage due to unauthorised removal
of the check valve
Removing the check valve from the tank line of hydraulic
hammer systems leads to destruction of the hydraulic
motor of the drum cutter.
u Never remove the check valve from the tank line of
hydraulic hammer systems.
The drum cutter is supplied with 3 hydraulic hoses, al-
ready installed by the manufacturer:
• Pressure line to the drum cutter
• Tank line with check valve to the carrier
• Leakage oil line to the carrier
