3.3.13 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 si-
gnals 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 cou-
pling of the mechanical constraints of the optional equi-
pment.
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 bu-
shings and the seals perfectly and to grease the pins sli-
ghtly 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.
