By means of a further hydraulic cylinder, boom
adjusting cylinder (4) the placing boom can be
adjusted (1).
The adjusting equipment offers advantages both

- better attachment mobility;
- easy transport of machine on trailers;
- observance of prescribed dimensions during road
travel.
WORKING WITH BOOM ADJUSTING
EQUIPMENT
By depressing pedal (1) forward, the adjusting cylin-
der retracts.
By depressing pedal (1) backward, the adjusting cyl-
inder extends.
With a specific menu, it is possible to suit the work-
ing speed of the adjusting cylinder to the operator
personal requirements and particularly to the work
requirements. During this operation the pedal con-
trol radius is adapted (1).
MACHINE TRANSPORT WITH BOOM
ADJUSTING EQUIPMENT
The best transport height, when the machine is
loaded on the trailer is achieved with:
- the adjusting cylinder completely retracted;
- the digging cylinder completely extended;
- the bucket cylinder completely extended.
The lifting cylinders have to be retracted so that the
attachment can lay as far as possible on the trailer.
