SAFETY DEVICE

8.9. SPIRIT AND ELECTRONIC LEVEL

Fig. 21 Visible spirit level

The spirit level is positioned on the turret and it is readily visible 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 level contained in the control board makes sure that this con‐

dition is effectively satisfied and checks the power supply to the controls for the

aerial part.

Always check the correct levelling of the machine after every self le‐

velling 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 authori‐

sed by the Constructor and in possession of suitable tools can intervene on

the spirit level.
