6.4.2.1 INSTALLING AND CONNECTING THE EQUIPMENT
WARNING
q
The machine must be parked on a level surface, with the equipment resting on the ground.
q
When the connecting pins are removed or installed, chips may come off; always wear gloves, safety
goggles and helmet.
q
The change of the equipment must be carried out by two operators, who must decide together the words
and signals to be used during work.
q
Avoid using your fingers to align the holes, since the may be injured or even cut off.
q
Before carrying out any operation on the hydraulic circuit, stop the engine and completely drain the re-
sidual pressure from the pipes.
For the installation of the equipment it is necessary to connect the
mechanical constraints of the bucket as described in "3.3.14
CHANGING THE BUCKET" and to carry out the hydraulic con-
nections using the pipes provided.

After connecting the mechanical constraints, carry out the hydrau-
lic connections by proceeding as follows:
1.
Stop the engine and move the hydraulic controls in all direc-
tions, in order to release the residual pressures present in the
circuits of the machine.
2. Press the optional equipment control pedal to release the re-
sidual pressure from the delivery pipe.
3. Slowly loosen the hydraulic oil filling cap, in such a way as to
release the residual pressure from the tank.
4. Remove the plugs of the quick couplers of both the machine
and the equipment.
5. Connect the right (1) and left (2) pipes.
CAUTION
q
When connecting the pipes, pay the utmost attention, in or-
der to prevent any impurities from getting into them, then
extend the bucket completely to avoid any interference
with the lever (A).
6. Start the machine and perform several manoeuvres with the
equipment control pedal, in order to check the seals.
WARNING
q
Wear thick gloves and safety goggles during this check.
q
To check the system for leakages, use a piece of cardboard
or a wooden board.
6.4.2.2 MAINTENANCE
