5.1.3.6.4 Danger red warning light (ZD)
It flashes quickly for 4 seconds together with the audible alarm at the machine start-up in case of fault during safety test on
controls (pedal, joystick control, switches, etc).
It is lit up steady together with the audible alarm when the chassis inclination exceeds the allowed value. All lifting operations
and telescopic extension are disabled (except JIB lifting). If the machine is lifted, drive is also disabled. It is necessary to lower
the booms completely and then place the machine onto a flat surface.
WARNING! The activation of this indicator warns of a dangerous situation since the machine has reached a
dangerous inclination level for the machine stability.
When the chassis inclination exceeds the allowed value, to prevent increasing the overturn risk, the
operator on the platform is recommended to retract the telescopic boom first and to lower it as the last
operation.
5.1.3.6.5 Overload red warning light (ZE)
Lit up flashing slowly with activation of audible alarm with a platform overload exceeding 20% the nominal load. If platform is
lifted, the machine is completely locked. If the platform is lowered all drive/steering operations are still possible but
lifting/rotation are disabled. Remove the overload before using the machine again.
Fast flashing in case of fault in the platform overload controller. With lifted platform the machine is completely locked. After
reading the manual instructions, trained staff can carry out an emergency manoeuvre for platform lowering.
WARNING! The activation of this indicator is a synonym of danger since the load at platform is exceeding
or no overload controller is active upon signalling.
For adjustment or activation in emergency situations read the MAINTENANCE chapter.
