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 dis-
tance 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 FOR
TRAVEL ON ROADS
1 - Remove the safety pins (4) and the pins (3).
2 - Make the forks slide towards the centre of the bucket,
overturn them and insert them in the supports (5).
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 sup-
ports (5).
If any slack should be observed between the forks and the
safety pin (3), immediately carry out the necessary adjust-
ment.
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.
CAUTION
q
The check and adjustment of the forks must be carried
out 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.
q
Before carrying out any movement with the machine,
make sure that the safety pins (4) are correctly inserted.
