Polluted hydraulic lines and connections may enable
sand, fragments of material and dirt to penetrate the hy-
draulic attachment and damage it completely.
u Clean the hydraulic lines and connections before
connecting the hydraulic hoses. Lay all hydraulic
hoses so that they are torsion-free.
n
Install the pressure and tank hoses.
n
Connect the pressure and tank hoses.
n
If no quick couplings are used, open the shut-off
valves in the installation at the boom.
n
Switch on the carrier.
n
Let the hydraulic oil run through the carrier oil filter for

WARNING Components bursting
Components of the swivel joint may burst. Metal parts
may become projectiles and cause serious injuries and
damage property.
u Always check the swivel joint covers are fitted prop-
erly when attaching the hydraulic breaker to the car-
rier.
u Tighten loosen screw connections (see chapter Bolt
connections / Tightening torques).
u Immediately replace a defective swivel joint cover.
n
Remove the caps from the ports »P« and »T« and
