The adapter plate must not be stopped by the
mechanical stops in either position. Consult the Atlas
Copco Customer Center/Dealer in your area if the
adapter plate is stopped by a mechanical stop.
Making the hydraulic connections
WARNING Hydraulic hose flailing about
Pressurised hydraulic hoses will flail about when
connecting fittings have come loose or have been
loosened. A hydraulic hose flailing about may cause
serious injuries.
►
Depressurise the hydraulic system before
disconnecting a hydraulic hose (see chapter
Depressurising the hydraulic system
).
►
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 incorrect 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.
►
Lay all hydraulic hoses so that they are
torsion-free.
♦
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
Total damage to the hydraulic attachment
Polluted hydraulic lines and connections may enable
sand, fragments of material and dirt to penetrate the
hydraulic attachment and damage it completely.
►
Clean the hydraulic lines and connections prior to
connecting the hydraulic lines.
♦
Install the pressure and tank hoses.
♦
Connect the pressure and tank hoses.
♦
If no quick couplings are used, open the shut-off
valves in the installation at the boom.
♦
Switch on the carrier.
♦
Let the hydraulic oil run through the carrier oil filter
for approx. three minutes to make sure that the
hoses are clean.
♦
Switch off the carrier.
♦
Depressurise the hydraulic system according to
the manufacturer's safety and operating
instructions for the carrier.
♦
If no quick couplings are used, close all shut-off
valves in the installation at the boom.
♦
Disconnect the pressure and tank hoses.
♦
Remove the screw covers from the ports »P« and
»T« and save them for future use.
♦
Make sure that the connections to the hydraulic
compactor and/or the carrier are not damaged.
♦
Replace any damaged connections.
