uncontrolled movements.

The described procedures are valid also for the coupling of the mechanical connections of the
optional equipment.
1. Position the bucket on level ground, directing it so that the
flat part of its back rests on the ground.
REMARK
Make sure the bucket is resting on the ground slightly to make
the removal of the pins easier.

When the pins are removed, check and note the number of
spacers used to adjust the clearance as this will be required in
the assembly.
2. Remove first the tie-rod pin (1) and then the arm
connection pin (2).
3. Change the bucket, taking care to clean the pins, the
bushings and the seals perfectly and to grease the pins
slightly before reinstalling them.
NOTICE
Install first the arm connection pin, making sure that the
seals are in good conditions.
4. Put back all the safety pins (3) and lubricate by means of
the appropriate grease nipple.
