6.8 CONFIGURATION FOR THE USE OF OPTIONAL EQUIPMENT
WITH UNIDIRECTIONAL OIL FLOW
WARNING
q
Some equipment that can be installed instead of the standard bucket make the machine unsuitable for
travelling on roads. Before travelling on roads, always make sure that the machine is homologated for
travelling with the equipment with which it is provided.
q
The installation and removal of the equipment that is not homologated for travelling on roads must be
carried out at the worksite or in any case in delimited spaces with no traffic.
6.8.1 DESCRIPTION AND CONTROL
The machine can be equipped with an independent hydraulic
circuit to be used for the operation of optional equipment that
may be installed on the backhoe instead of the standard bucket.
6.8.1.1 CONTROL (version with mechanically-
controlled backhoe)
The circuit is piloted by an additional hydraulic distributor that
is operated by means of a pedal (1) installed on the left side of
the backhoe control lever unit.
The additional circuit is operated as follows:
1 - When the pedal (1) is pressed with the toe, oil is delivered
to the right side of the circuit and discharged from the left
side of the same.
2 - When the pedal (1) is pressed with the heel, oil is deliv-
ered to the left side of the circuit and discharged from the
right side of the same.
The movements of the levers described at point "3.3.6.1 pos.
18/19 - BACKHOE CONTROL LEVERS (version with me-
chanical controls)" remain unchanged, except for the bucket
control, which is used for positioning the optional equipment.
This configuration includes also the fixed installation of the de-
livery and discharge pipes that convey/discharge the oil nec-
essary for the operation of the equipment and reach the
proximity of the equipment connection.
6.8.1.2 CONTROL (version with servo-assisted
backhoe)
In the version with servo controls, the additional circuit is oper-
ated via the buttons (2) and (3) positioned on the left joystick
lever. The movements of the levers described in "3.3.6.1 pos.
18/19 - BACKHOE CONTROL LEVERS (version with servo
controls)" remain unchanged.
The additional circuit is operated as follows:
1 - When the push button (2) is pressed, oil is delivered to the
right side of the circuit and discharged from the left side of
the same.
2 - When the push button (3) is pressed, oil is delivered to the
left side of the circuit and discharged from the right side of
the same.
IMPORTANT
q
All movements of the boom, the arm and the equipment
are inhibited when the safety button is in locking posi-
tion (see "3.3.2 pos. 12 - SERVO CONTROL LOCKING
BUTTON").
