7.2.11. Inclinometer operation check
WARNING!
Usually the inclinometer does not need to be adjusted unless the electronic control unit is replaced. The
equipment necessary for the replacement and adjustment of this component is such that these
operations should be carried out by skilled personnel.
AS THIS OPERATION IS VERY IMPORTANT IT IS TO BE CARRIED OUT BY SKILLED TECHNICIANS
ONLY.
The inclinometer does not require any adjustment since it is
calibrated in the factory before the machine is delivered.
This device controls the chassis slope and when inclined over
the allowed value:
▪
It disables lifting.
▪
It disables drive when platform exceeds a given height
(varying according to model).
▪ It warns of the instability condition by means of an audible
alarm and a warning light located on the platform (see
chapter “General use instructions”).
The inclinometer checks the inclination with respect to the two
axes (X; Y). On machine models that have the same transversal
and longitudinal inclination limits, the control is carried out with
reference to one axis only (X-axis).
Check operation at least once a year.
To check the inclinometer operation according to the
longitudinal axis (generally X-axis ):
▪ Using the platform control panel set the machine so as to
place a shim of dimension (
A+10 mm ) under the two rear or
front wheels (see following table).
▪ Wait three seconds (operation delay set at factory) until the
danger red light and the platform audible alarm turn on. With
platform lowered (booms down, and jib at a height between
+10° and
– 70°) all manoeuvres are still possible. By lifting
one of the booms (excepting the Jib) and/or extending the
telescopic boom with respect to the horizontal, the control
system of the machine disables the lifting and drive controls.
▪
If the alarm does not go off CALL THE TECHNICAL
ASSISTANCE.

To check the inclinometer according to the transversal axis (normally Y-Axis ):
▪ Using the platform control panel set the machine so as to place a shim of dimension ( B+10 mm ) under the two side right
or left wheels (see following table).
▪
Wait three seconds (operation delay set at factory) until the danger red light and the platform audible alarm turn on. With
platform lowered (booms down, and jib at a height b10° and
– 70°) all manoeuvres are still possible. By lifting
one of the booms (excepting the Jib) and/or extending the telescopic boom with respect to the horizontal, the control
system of the machine disables the lifting and drive controls.

If the alarm does not go off CALL THE TECHNICAL ASSISTANCE.
