(6) Shut down the engine.
(7) Depressurise the hydraulic lines by alternately pressing
both buttons (4-11/2) at the pilot valve for working and
auxiliary hydraulics (4-10/1) several times.
(8) Pull off the protective caps from the hoses of the quick-
change device (6-4/1).
(9) Swing up the protective flaps of the quick-change
couplings on the multi-purpose bucket (6-4/3) and connect
them with the hoses of the quick-change device (6-4) by
tightly pushing them in.
CAUTION
When making connections, make sure that the
hydraulic connections are clean and completely
connected.
Dismounting
NOTE
When the uncoupled attachment remains in the
sun for a longer period of time, the hydraulic oil
in the cylinders will heat up. This will build up a
pressure in the hydraulic cylinder that makes it
much more difficult to connect the hydraulic lines
to the hydraulic connectors later.
To avoid this issue, we recommend the following
procedure of depositing the multipurpose bucket
on the ground:
(1) Completely lower the bucket arm.
(2) Fully tilt up the multipurpose bucket.
(3) Close multipurpose bucket to approx. 20 cm.
(4) Shut down the engine.
(5) Depressurise the hydraulic lines by alternately pressing
both buttons (4-11/2) at the pilot valve for working and
auxiliary hydraulics (4-10/1) several times.
NOTE
The multipurpose bucket closes unpressurised.
(6) Open the protectors of the quick-change couplings on
the multi-purpose bucket (6-4/3) and separate them from
the hoses of the quick-change coupling by strongly pulling
the knurled rings on the hoses of the multi-purpose bucket
(6-4/2).
(7) Fit the protective caps on the hoses of the quick-
change device (6-4/1).
(8) Start the engine and set the bucket safely to the
ground.
