13 - CUTTING-OFF "AGGRAVATING" HYDRAULIC MOVEMENTS
The function which cuts hydraulic movements is used to automatically stop dangerous movement of the jib when you are close to
the limit of longitudinal stability. However, lateral stability can reduce the load chart in its upper part and this reduction is not
detected by the longitudinal stability alarm.
The operator must respect the lift truck's load chart.
All attachments with a suspended load (winch, crane jib, crane jib with winch, hook, etc.) MUST be used with a lift truck equipped with
a working hydraulic movement cut-out device.
1st FITTING
OPERATION
Switch A allows you to cut off "AGGRAVATING" hydraulic movements or not.
WITH CUT-OUT OF "AGGRAVATING" HYDRAULIC MOVEMENTS: SWITCH A IN POSITION
A2 (VISUAL INDICATOR OFF):
Led B4 indicates that the lift truck has reached the authorized limit of longitudinal
stability and all aggravating hydraulic movements are neutralised.
The sound alarm goes off at the same time.
- To restart hydraulic movements, only perform de-aggravating hydraulic movements in the
following order: jib retracted and raised.
NOTE: When the jib is retracted, the function for switching off "AGGRAVATING" hydraulic movements is disconnected.
WITHOUT CUTTING-OUT "AGGRAVATING" HYDRAULIC MOVEMENTS: SWITCH A IN POSITION A1 (VISUAL INDICATOR ON):
To allow the use of loading or earth moving buckets, for example.
In this case, the user is only informed by the longitudinal stability alarm system B (see: 2 - DESCRIPTION: 5 - LONGITUDINAL
STABILITY ALARM SYSTEM).
Hydraulic movements are not cut off.
The sound alarm is disconnected.
See operator's manual for use and description.
NEUTRALIZATION OF HYDRAULIC MOVEMENTS: SWITCH A IN POSITION A3 (VISUAL INDICATOR PARTIALLY ON):
When driving on the road, it is highly recommended (mandatory in Germany) that you cut-off all the hydraulic movements.
2nd FITTING
OPERATION
Switch A allows you to cut-off "AGGRAVATING" hydraulic movements or not. The cutting-off
of "AGGRAVATING" hydraulic movements is automatically enabled when the lift truck is
started-up.
WITH CUT-OUT OF "AGGRAVATING" HYDRAULIC MOVEMENTS: VISUAL INDICATOR A1 OFF:
- Led B4 indicates that the lift truck has reached the authorized limit of longitudinal
stability and all aggravating hydraulic movements are neutralized.
- The sound alarm goes off at the same time.
- To restart hydraulic movements, only perform de-aggravating hydraulic movements in the
following order: jib retracted and raised.
NOTE: When the jib is retracted, the function for switching off "AGGRAVATING" hydraulic
movements is disconnected.
WITHOUT CUTTING-OUT "AGGRAVATING" HYDRAULIC MOVEMENTS: TAB 'C 'HELD DOWNWARDS AND SWITCH 'A' IN POSITION 'A1'
(VISUAL INDICATOR ON):
- To allow the use of loading or earth moving buckets, for example.
- In this case, the user is only informed by the longitudinal stability alarm system B (see: 2 - DESCRIPTION: SPECIAL ADAPTATIONS:
2 - LONGITUDINAL STABILITY ALARM SYSTEM).
NEUTRALIZATION OF HYDRAULIC MOVEMENTS: SWITCH 'A' IN POSITION 'A3' (VISUAL INDICATOR OFF):
- When driving on the road, it is highly recommended (mandatory in Germany) that you cut-off all the hydraulic movements.
