Technical data
Wrong manoeuvring: the crane can fall break or overturn if the operator 
performs a wrong manoeuvre due to the lack of familiarity with the opera-
tion procedures (see manual of use and maintenance) or due to inadequate 
psychophysical conditions: we remind you that the directives in force impose 
a suitable training of the personnel before using these types of machines and 
require an adequate psychophysical condition to operate safely a lifting device 
that always implies the intrinsic danger of a lifted load.
Weather conditions: too high or too low temperatures may damage the 
components of the oleodynamic and electric circuits (See max and min conditions 
of use); it is forbidden to operate the crane during a storm with lightning hazards, 
so we recommend to fold it and put it to rest. Furthermore when the wind is too 
strong the crane can overturn or break down.
Shearing, entrapment: the crane has a lot of parts in movement that it is 
impossible to cover; therefore the operator shall always be aware of this residual 
risk and keep clear from the parts in movement, particularly from the load; the 
operator is held responsible not only for himself but also for those working in 
proximity of the crane and for those who may draw closer even if not authorized.
Electricution: the crane is not insulated from electric contacts and therefore it is 
not equipped to work under tension, even if the contact is accidental. Therefore 
be compliant with the min clearance prescribed by the national directives in 
force. Generally speaking the clearance from electric lines with a max tension 
of 38.000 volts should be at least 5 meters: Higher tensions require higher 
clearance to be verified case by case together with competent technicians and 
with respect to the environment conditions.
Manual extension overload: manual extensions are controlled by the moment 
limiting device only under the conditions described in the relative chapter; the 
control system of the manual extension overload must be activated by the 
operator as described.
Accessories: be careful when assembling and disassembling the accessories 
(extensions, buckets, baskets,…); first verify the weight, the securing systems 
and the instructions for assembly and dismantlement; then appraise their 
barycentre and provide for adequate provisional blocking systems in order to 
avoid sudden movements.
(!) ATTENTION (!)
IF IN THE FOLDING CONDITION THE HOOK IS OUT OF TRUCK SIZE, IT 
MUST BE TAKEN AWAY BEFORE TRAVELLING.
Breakdown of some sensors
The system "moment limiting device - intelligent type" is always monitored 
during ignition (the system, after having activated the various circuits, checks 
the presence of all the inputs for around 4 seconds) and then continuously 
monitors the operation and the efficiency of the limiting device (approx. every 
25 milliseconds).
For most of the components the system checks also the congruence of the 
incoming signal with the one the system expects.
Maintenance: maintenance is particularly important; the lack of it may damage 
things or hurt people.
Particular operations: if you are required to operate under particular conditions 
not illustrated in the manual of use and maintenance, analyse carefully the 
situation and always refer to an authorised Fassi shop or to the Fassi technical 
support service or to experienced operators before starting working.
