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 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! Pressure and tank
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.
♦
If no quick couplings are used, close all shut-off
valves in the installation at the boom.
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.
