Zebra 16 Stab
2.3. OUTRIGGERS
The machine is fitted with four outrigger cylinders allowing the chassis to be levelled before
raising the work platform.
The outrigger control is only possible when the machine is lowered.
The chassis is always levelled in automatic mode.
Automatic levelling
1- Select the platform control station and start the heat engine.
2- Depress the enable pedal.
The green indicator lights up.
3- Within 5 seconds, push the switch forward to extend the outriggers:
The engine speed increases.
The red outrigger position indicator switches on.
4- Once the four outriggers contact the ground:
The green outrigger ground contact indicator flashes.
The engine speed slows down.
The levelling sequence starts.
5- Keep the switch pushed forward until:
The outrigger ground contact indicator is on steady.
The tilt indicator switches off.
An acoustic signal (2 quick beeps) sounds.
The outrigger movement stops automatically when the chassis is level.
6- To retract the outriggers, fully lower the platform then pull the switch backwards.
The engine speed increases.
As soon as the outriggers no longer contact the ground the red indicator lights up.
The outrigger movement stops automatically when they are fully retracted..
An acoustic signal (3 quick beeps) sounds
7- Drive movements are authorised.
Automatic levelling failure
1- Loss of contact with the ground during the automatic levelling sequence.
If an outrigger loses firm contact with the ground:
The levelling sequence is interrupted.
The red indicator for loss of ground contact lights up.
- Check the ground condition and resistance or that there are no objects under the
outrigger pads.
- If need be move the machine on firmer grounds.
Prior to restart a new automatic levelling sequence, the four outriggers must be retracted until
none of them contact the ground (system reset).
2- Outrigger cylinders reaching the end of their course or tilt aggravation detection.
If the outriggers reach the end of their course before the chassis is level or if the chassis tilt
gets worse instead of being corrected: the levelling sequence is interrupted.
- Check the ground condition and surface.
- If need be move the machine to a surface where it will be possible to level the machine.
