WARNING AND
INSTRUCTIONS
GRU FASSI
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.
The operator must consider the ambiental conditions: a wind gust can cause
the crane swinging, and so a contact with the electric lines.
The minimum distance of safety can differ according to typ of the electric line.
It's obligatory to respect the regulation in force in the country of use for to can
operate in safety.
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.
It's prohibited to overload the extensions over the indicated limits in the capaci-
ty plates.
In the chapter "3 Capacity plates" are indicated the maximum capacity of the
manual extensions.
ACCESSORIES
Be careful when assembling and disassembling the accessories (extensions,
buckets, baskets,…): verify the weight, the securing systems and the instruc-
tions for assembly and dismantlement, then appraise their barycentre and
provide for adequate provisional blocking systems in order to avoid sudden
movements.
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.
It's obligatory to replace the damaged or spoilt components for to work with
safety, and for to obtain the best performances of the crane.
MAINTENANCE
Maintenance is particularly important: the lack of it may damage things or hurt
people.
In the chapter "22 Maintenance instructions" are described all the operations
for to maintain efficient your crane, and to avoid serious damages to things and
persons caused by the crane malfunction for the scarce or null maintenance.
(!) ATTENTION (!)
The FASSI GRU declines every responsability for the spoilts, the breakin-
gs or the damages caused by the maintenance failing.
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.
