ANUAL LEVELLING OF THE
B
ASKET
The elevating work platform is provided with an automatic basket levelling device that was
designed so that the basket floor is always parallel to the ground independently of the move‑
ments of the arms.
However, due to causes such as leaks and malfunctions, it may be necessary to operate
manually to bring the basket to the optimal position. Proceed as follows to make such adjust‑
ments:
‑
try to move the basket to the travel position by closing the extensible structure comple‑
tely (this, only if the problem occurred while the basket was in a raised position);
‑
only carry out this operation if the basket angle exceeds 10°. If this is not the case, carry
out manual levelling at the minimum possible height, within the limit of 10°. The mini‑
mum height is reached by completely closing the 1st and 2nd arm, extension arm, jib
arm and, as much as possible, the 3rd arm;
‑
unscrew the safety screw, first loosening its lock nut
(two 13 mm fixed spanners are needed to perform this
operation) until releasing the control (see photo);
‑
raise the safety device against the accidental operation of the control and operate it very
gently until the basket is levelled, also lowering the engine speed;
‑
gently release the lever to the neutral point and put the safety screw back in position,
finally tightening its lock nut.
Basket levelling is subjected to some conditions:
‑
it is an exceptional manoeuvre to be performed only in case of slight malfunctions of the
self‑levelling procedure, therefore if the problem occurs frequently, have the basket
checked by an authorised workshop;
‑
the manual levelling control can be operated only from the basket, otherwise the opera‑
tor runs the risk of being injured following contact with moving parts of the machine;
‑
it is absolutely forbidden to use the levelling manoeuvre for purposes other than those
described herein (e.g. to lift objects, to increase the reach of the platform etc.), in order to
avoid serious and even fatal accidents.
