PALLET FORKS
6.4.3.1 PREPARING THE PALLET FORKS FOR
USE
1 - Overturn the forks toward the front part of the machine.
2 - Lift the bucket and operate the control lever in such a way as
to swing it forward until releasing the forks from the bucket
teeth.
3 - Move the forks (1) sidewards to widen or narrow the distance
between them according to the width of the load to be
handled.
4 - Fold the bucket and manoeuvre the lifting arm until the forks
are in horizontal position.
5 - Lubricate the fork rotation pins (see "4.5.2 LUBRICATION
DIAGRAM (4in1 bucket and pallet forks)").
6.4.3.2 OVERTURNING THE FORKS
1 - Remove the safety pins (4) and the pins (3).
2 - When at rest, the forks may be arranged in two different
positions, and precisely:
• FOR TRAVEL ON ROADS
(Only for machines with approval for travel on roads):
make the forks slide towards the centre of the bucket, overturn
them and insert them in the supports (5) as shown in Figure A.
It is also compulsory to install the locks as described in
paragraph "3.1 SAFETY LOCKS".
• DURING WORK:
make the forks slide towards the outside of the bucket, overturn
them and insert them in the supports (5) as shown in Fig. B.
During work, avoid keeping the forks as represented in
q
Figure A, since they may make contact with the engine
hood.
3 - Put back the pins (3) and the safety pins (4).
4 - Make sure that when they are overturned in rest position the
forks are firmly secured inside their respective supports (5).
If any slack should be observed between the forks and the
safety pin (3), immediately carry out the necessary
adjustment.
The correct adjusting procedure is as follows:
- Release the stop nut (10) and loosen the adjusting screw (11)
until taking up the slack between the fork and the safety pin (3).
Use a 22 mm hex wrench.
- After the adjustment, tighten the stop nut (10) thoroughly. If the
adjusting screw (11) should be excessively worn, do not hesitate
to replace it.
The check and adjustment of the forks must be carried out
q
on both sides, with the forks at rest. Do not hesitate to
adjust the forks as soon as the presence of a slack is
noticed. Non-compliance with these instructions may lead
to dangerous situations for the operator and cause serious
damage to the machine.
Before carrying out any movement with the machine, make
q
sure that the safety pins (4) are correctly inserted.
