POSITION 5:
Position 5 displays the icon confirming that overhead
movements are enabled.
Figure 6-11.
This icon means that all conditions for using the overhead
movements have been checked and the aerial part can be
lifted. No icon on means that the aerial part cannot be
lifted.
In place of this icon, the basket overload icon may be
shown.
Figure 6-12.
When the load sensor measures a load exceeding the
allowed work load - 230 kg - the main screen disappears
for three seconds, replaced by the overload error display,
the audible warning is activated, then the overload icon
appears in position 5 in place of the icon enabling the
overhead movements.

stabilizers cannot be used and the track cannot be
extended. The machine, however, can travel even when
the icon is off, as long as all 4 stabilizers are lifted from the
ground.
