USING THE WORK EQUIPMENT
3.13.4 CHANGING THE BUCKET
DANGER
•
When the coupling pins are removed or installed, chips
may come off; always use gloves, goggles and helmet.
•
The change of the equipment must be carried out by two
persons, who must decide together the words and signals
to use during operations.
•
Do not use your fingers to center the holes, since they
may be injured or even cut in case of sudden or uncon-
trolled movements.
•
The described procedures are valid also for the coupling
of the mechanical constraints of the optional equipment.
1 - Position the bucket on a level surface, directing it so that the
flat part of its back rests on the ground.
2 - Remove the tie rod pin (1) and the arm connection pin (2).
3 - Change the bucket, taking care to clean the pins, the bush-
ings and the seals perfectly and to grease the pins slightly
before reinstalling them.

Install first the arm connection pin, making sure that the
seals are in good conditions.
