Note:
Do not perform two movements at the same time, perform only one movement at a time.
Note:
On the valve that controls the outreach there is an accessory to facilitate the retraction
procedure; the same device can also be installed on the valve that controls the movements of the
boom.
These operations are to be performed with:
1)
Combustion or electric engine off;
2)
Electrical system switched off (by disconnecting the switch-battery).
These operations simulate emergencies that can happen to the machine such as:
1)
Electrical system faulty;
2)
Hydraulic system faulty;
3)
Motors faulty.
ATTENTION:
During this procedure all the machine safety devices (load control, outreach control
and tilt control) are deactivated.
ATTENTION:
Carefully perform all movements as there is a constant danger of the machine
overturning and overloading of the structure.
It is therefore necessary to always perform the following sequence of movements:
1.
Complete retraction with extension of the telescopic boom;
2.
Full lowering of the JIB;
3.
Rotation of the slewing ring to bring the column back into a centred position (slewing ring
angle 0°);
4.
Complete lowering of the telescopic boom.
ATTENTION:
THIS MECHANISM MUST ONLY BE USED IN AN EMERGENCY, i.e.
ELECTRICAL OR HYDRAULIC FAILURE.
Transporting the machine in an emergency
To move or transport the platform using external equipment, refer to paragraph 2.5.
