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.
►
Only use hydraulic lines of the rated sizes as
instructed (see chapter
Technical Specifications
).
►
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 diameter and wall thickness.
►
Route all hydraulic hoses in a torsion-free manner.
♦
Switch off the carrier.
♦
Depressurise the hydraulic system according to
the manufacturer's safety and operating
instructions for the carrier.
♦
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
hydraulic attachment and damage the hydraulic parts.
►
Clean the hydraulic lines and connections prior to
connecting the hydraulic lines.
♦
Have dirty hydraulic lines rinsed through by a
specialist company.
♦
Clean dirty hydraulic line connections with a
suitable grease-dissolving universal cleaner.
♦
Observe the cleaner manufacturer's information
on safety and use.
Connecting hydraulic hoses for the functions
»Open / close«
♦
Remove the blank flange from the connections
»A«
and
»B«
at the upper part of the hydraulic
demolition cutter and keep them in a safe place.
The connection of function
»Open«
is marked with
an
»A«
, the connection of function
»Close«
with a
»B«
at the edge of the connecting plate of the upper
part.
♦
Check that the connections on the hydraulic
demolition cutter and on the hoses are not
damaged.
♦
Change any damaged connections.
♦
Grease the flange O-rings with Parker O-Lube and
insert them.
♦
Position hose flange for connection
»A«
.
♦
Fix the flange halves on both sides of the flange
with the fixing screws.
♦
Position other hose flange for connection
»B«
.
♦
Fix the flange halves on both sides of the flange
with the fixing screws.
When both input lines have the same operating
pressures,
♦
connect the two hoses at the boom in a
torsion-free manner.
If the two input lines have different operating
pressures,
♦
connect the hose connected to connection
»B«
to
the input line which has the higher operating
pressure in a torsion-free manner.
♦
Connect the hose connected to connection
»A«
to the input line which has the lower operating
pressure in a torsion-free manner.
WARNING Hydraulic hose flailing about
Pressurised hydraulic hoses will flail about if a bolted
connection comes loose or becomes loosened. A
hydraulic hose flailing about may cause serious
injuries.
►
Tighten the fastening screws with the right
tightening torque.
Tightening torque (see chapter
Bolt
connections/Tightening torques
