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
before connecting the hydraulic hoses. Lay all
hydraulic hoses so that they are torsion-free.
◆
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.
WARNING Components bursting
Components of the swivel joint may burst. Metal
parts may become projectiles and cause serious
injuries and damage property.
►
Always check the swivel joint covers are fitted
properly when attaching the hydraulic breaker
to the carrier.
►
Tighten loosen screw connections (see chapter
Bolt connections / Tightening torques).
►
Immediately replace a defective swivel joint
cover.
◆
Remove the caps from the
ports »P« and »T« and save them for future
use.
The pressure port »P« has been marked with
red paint as an extra reference.
◆
Check that the ports and connections on the
hydraulic breaker and/or on the hydraulic hoses
are not damaged.
◆
Replace any damaged connections.
◆
Connect the pressure hose to port »P«, making
sure it is torsion-free.
◆
Connect the tank hose to port »T«, making sure
it is torsion-free.
WARNING Hydraulic hose flailing about
Pressurised hydraulic hoses will flail about when
bolted connections have come loose or have been
loosened. A hydraulic hose flailing about may
cause serious injuries.
►
Tighten the hydraulic hose connection nuts with
the required tightening torque.
Tightening torque (see chapter Bolt connections /
Tightening torques)
