respect the instructions requested by the manufacturer of the lifting device, and those
highlighted in the safety data sheet of the product which must be weighed.
Laws and national norms
Before putting into service and while using it, the user must verify that all norms in force in the
Country where the instrument is used in regards to “safety and prevention of casualties” and
“metrology” are respected.
It is also important to take into account and respect the laws and guidelines for the safety
controls of the Country of use.
Carefully respect all the safety measures and maintenance
General warnings
The electronic crane scale is to be considered a scale, and
therefore use must be limited only to weighing needs. The
crane scale is not designed for cargo handling and
transportation. Once the load harnessing operation is done,
move away, and make sure that the load is well balanced lifting
it up only a few centimetres from the ground and then lift the
load down to the ground again. Remove the crane scale at the
end of the weighing operations.
Do not stand or pass under a suspended load

4
DO NOT exceed the nominal capacity of the crane scale.
(The illustration refers to the model 6t. Refer to the maximum
capacity of the purchased instrument).
The nominal capacity of the electronic crane scale must not be
lower than the maximum capacity of the lifting device.
DO NOT exceed the nominal capacity of any support element of
the load if lower than the capacity of the crane scale.
Use the scale EXCLUSIVELY for the lifting and the weighing of
suspended loads and for TENSION measurements.
Suspended loads which may cause applied torsion stresses
MUST be hung with flexible or swivelling bindings.
Carefully respect all the safety measurements established by
the manufacturer of the electronic crane scale, which are shown
in the instruction manual.

5

trained personnel. Entrust the execution of maintenance
operations only to trained personnel in security controls for
lifting devices.
DO NOT spill liquid on the instrument. Respect the IP degree
protection of the instrument.
DO NOT use solvents or industrial chemicals for cleaning the
instrument.
The crane scale is to be considered like a scale, and therefore it must be used only for
weighing needs. The crane scale is not designed for cargo handling and transportation.
Once the load harnessing operation is done, move away and make sure that the load is well
balanced lifting it up only a few centimetres from the ground and then lift the load down to the
ground again. Remove the crane scale at the end of the weighing operation. An improper or
different use than what is foreseen in this manual, will release the Manufacturer from all
responsibilities in case of damages caused to people or things.

-do not use the electronic crane scale where there is non-compliance with the safety
checklist.
-any maintenance, repair or cleaning should be done away from danger areas and with the
electronic crane scale turned off.
Daily monitoring
Each time the operator starts a new work cycle with the electronic crane scale, one must:
-check all instrument parts;
-carry out a general visual inspection of the whole system;
-Check the integrity and efficiency of all parts of the weighing system like the safety lever of
the hooks, the locking nuts screwed well with the pin, the shackles, etc..

12
Regular Maintenance
Maintenance should be carried out only by persons who have acquired the necessary
technical expertise and are specialized and trained for this purpose.
Every 3 months
-Check all dimensions of the parts which make up the
instrument;
-Check the wear on the handle or the eyelet, by
checking if there are any plastic deformations,
mechanical damages(irregular), cracks, corrosion,
damage to threaded portions and the twists;
-Check the tightness of the splice plate on the hook,
and the presence of defects, and ensure its proper
functioning;
-Make sure that the split pin and the shackle nuts are
firm;
-If other metrological and mechanical irregularities
are detected, have the electronic crane scale
repaired by qualified personnel (authorized
assistance service).
An incorrect measurement of weight may be a sign
of a mechanical problem with the crane scale. If the
crane scale weighs incorrectly, the crane scale must
be repaired by skilled personnel (Authorized Service
Center).
Do not for any reason carry out the repair by
yourself.
In case of non-compliance turn immediately off the
electronic crane scale.
All repair operations and the parts used are
classified and stored in the maintenance register.
Every 12 months
All of the elements that transmit the load, including the
load cell, should be checked by specialised personnel
qualified in inspection and maintenance of cranes and
bridge cranes.
It is of utmost importance that all the maintenance and repair operations, and the used
components are recorded and filed in the appropriate product maintenance registry.

Form and structure of the shackle:
The shackles should be examined regularly by a qualified person. The time interval from one
check to another depends on how much the instrument is used, but it is recommended to not
exceed six months.
Therefore, one must:
-always inspect the shackle before use;
-carry out regular visual inspections to look for nicks, cracks, wear or damaged areas,
damaged threads on the pivot and body; if it is necessary, carry out a magnetic test or non-
destructive testing;
-keep a file in regards to the accessory sheet and keep track of the checks;
-the shackles which do not fully or partially satisfy the requirements, must be discarded.

15
Maintenance registry
In order to cope with problems like the wear of the mechanic and electronic components, and
the grip load devices, it is necessary that one carries out a regular and systematic
maintenance.
The maintenance and respective time intervals must take place according to the indications of
the manufacturer shown in the instructions manual of the instrument.
The maintenance interventions must be made only by specialised and qualified personnel.
The maintenance person must have attended training courses and must know the safety
norms in the use of crane scales and concretely apply them.
In this booklet the user must document in chronological order all the maintenance interventions
carried out on the crane scale (inspection/control, revision, repair), as well as any fact or
particular event which might have influenced safety matters.
Upon receipt of the crane scale, or at least before the commissioning of the instrument, record
all dimensions of the hooks and shackles in the service manual. All subsequent dimensional
checks specified in the plan check and maintenance, will be compared with the first
measurements and the tolerance limits given in the above table, refer to the actual size
detected in the first inspection.
In the following pages of this booklet there is a “maintenance registry” in which all ordinary and
extraordinary maintenance interventions on your instrument, should be reported.
All information is very important and can invalidate the validity of the warranty in the case that
it’s not reported in detail and accurately. It is also advisable to make sure that:
- the internal responsible person carries out the quarterly verification and regularly records it on
this booklet;
- the authorised personnel stamps the appropriate box at the end of each annual maintenance
intervention.
