From each control box, a buzzer alerts the operator that the machine is not folded/stowed and
is positioned on a slope exceeding the slope allowed.
N.B.-:-The slope sensor is only active when the platform is not in the stowed position.
When the unfolded machine is on a slope greater than the rated slope, out of the stowed
position, DRIVE and LIFT functions are disabled(For CE and AS only).
All functions speeds are reduced.
In this case, fully lower the platform and reposition the machine on level ground before raising
the platform again.
To restore the disabled functions, perform the following movements :
