• FRONT ANTI-TIP-OVER CONTROL
The front anti-tip-over control device steps in when the machine is close to its longitudinal stability limit, and locks all
aggravating movements.
During handling operations, the system automatically detects and processes the position of the lifted load and the machine's
stability percentage. These values are shown on the display D) in the cab in 3 different ways:
- icon of the lifting position (indicator (219) green - yellow - red)
- led icon of the machine's stability condition indicator (210) (green - yellow - red)
- percentage icon (211) of the longitudinal stability limit
The number displayed at point (211) refers to 3 stability conditions:
• 0%-90% (Fig.1)
-
machine stable and no movement block
- indicator (219) is green
- graphic bar (210) has green LEDs on
• 90%-100% (Fig.2)
-
close to the longitudinal stability limit and no movement block
- indicator (219) on load chart is yellow
- graphic bar (210) has yellow LEDs on
- buzzer sounds intermittently in cabin. The sound becomes more frequent as it reaches 100% (red zone)
• over 100% (Fig.3)
-
longitudinal stability limit reached with consequent block of movements that may worsen the condition
- instrument panel warning light (54) comes ON
- indicator (219) on load chart is red
- graphic bar (210) has red LED on
- buzzer in the cab sounds continuously
To restore safe machine operating conditions (indicator (219) and led graphic
bar (210) - green), the telescopic boom must be retracted.
If either it's not possible to retract the telescopic boom or this manoeuvre is not
sufficient to restore safe operating conditions for your machine, turn operating
mode selector (6) to the "C" position and hold it in that position. Then proceed
slowly and very cautiously with non-aggravating manoeuvres until safe operating
conditions are restored (both warning light 54 and audible alarm in the cab are
off; indicator light (219) and graphic bar (210) - green).
WARNING!
Before working with the machine, test the warning and overload systems.
With the boom just above the ground, pick up a load and extend the boom
to the point of overbalance. In the event of malfunction do not use the
machine until the fault has been repaired.
