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.
IMPORTANT
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.
