3.8 CONTROL PROTECTION
A protection structure is provided to protect the remote control against the accidental fall of
objects from above and involuntary activation by the operator.
Always make sure that this protection structure is intact before using the machine.
3.9 SPIRIT LEVEL
The spirit level is positioned on the turret and it is readily visi‑
ble from the basket and from the ground. The spirit level must
be used to make sure that during the platform levelling phase
the maximum allowable gradient of 1° is complied with. This
condition is met when the air bubble is inside the green area.
A second electronic spirit level contained in the control board
makes sure that this condition is effectively satisfied and checks the power supply to the con‑
trols for the aerial part.
Always check the correct levelling of the machine after every self‑levelling operation.
Approximate levelling outside of the limits set by the manufacturer is very dangerous and
can affect the stability of the platform, which represents a risk, even deadly, for the operator
and other persons working on the machine and near it.
Never intervene on the spirit level adjustments; this device is calibrated by the Constructor
during the inspection before sale. Only technicians authorised by the Constructor and in pos‑
session of suitable tools can intervene on the spirit level.
