7 - LONGITUDINAL STABILITY WARNING
UP TO MACHINE N°: 590612 AND EXCEPT FOR MACHINES N°: 589029 ; 589122 ; 589165
This device warns the operator of the lift truck’s longitudinal stability limits. However, lateral stability can reduce the load chart in
the upper part, and this reduction is not detected by the device.
The operator must respect the lift truck’s load chart.
A - VISUAL ALARM
A1 - A2 - A3: There is a significant reserve of longitudinal stability.
A4 - A5: The lift truck is approaching the limit of longitudinal stability, move with
care.
A6: The lift truck is very near at the limit of longitudinal stability. The alarm sounds
simultaneously with a slow intermittent sound. Move with care.
A7: The lift truck is very near at the limit of longitudinal stability. The alarm sounds
simultaneously with a fast intermittent sound. Move with extreme care.
A8: The lift truck is at the authorized limit of longitudinal stability. The acoustic
alarm simultaneously starts to beep. All “AGGRAVATING” hydraulic movements
are stopped. Only make hydraulic movements that increase stability in the
following order; retract and raise the jib.
B - SOUND ALARM
This allows you to switch off the sound alarm when using the lift truck with loading and
earth moving buckets. When it is switched off, the red warning light indicates that the
sound alarm has been cut off and that only the visual alarm is working. Under all other
operating conditions, the sound alarm must be switched on.
C - CUTTING OFF THE “AGGRAVATING” HYDRAULIC MOVEMENTS
This switch allows you use or not use the cut-off for the “AGGRAVATING” hydraulic
movements. The cut-off of “AGGRAVATING” hydraulic movements is automatically enabled
when the lift truck is started-up.
- Place the lift truck in the transport position, with the jib lowered and retracted.
WITH CUT-OUT OF “AGGRAVATING” HYDRAULIC MOVEMENTS: VISUAL INDICATOR C1 OFF:
NOTE: When the jib is retracted, the function for switching off “AGGRAVATING” hydraulic
movements is disconnected.
WITHOUT CUTTING-OUT “AGGRAVATING” HYDRAULIC MOVEMENTS: VISUAL INDICATOR C1 ON:
- To allow the use of loading or earth moving buckets, for example.
In this case, only the visual and sound alarm will inform the user.
D - STRAIN GAUGE
Disassembly or adjustment of the strain gauge is prohibited, this must only be done by specially trained
personnel, consult your dealer.
