PIRIT 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 condi‑
tion 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 controls 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 tamper with the spirit level; this device is set by the Constructor during testing before
sale. Only technicians authorised by JLG using suitable tools may adjust the spirit level.
