7.3 During operation
Locate and delimit the working area.
Make sure that no one is within the working area of the crane. Do not stop and
do not pass in the delimited area.
Choose the correct control position, making sure to have the complete visibility of
the
working area.
Stabilize the vehicle on a horizontal plane with a maximum tolerance of 1,5
degrees.
Check the vehicle inclination on the levelness indicator. The bubble must
be contained in the internal circle, and in any case it doesn't must to come out from
the external circle.
Make sure that the outrigger rams rest on a solid base. If necessary use larger
outrigger base plates (available on request) to avoid sinking. If you adopt other
means, make sure that they are suitably sized for the load they must bear.
(!) ATTENTION (!)
The stability of the unit (crane-vehicle) is only guaranteed by the complete
lateral extension of the outriggers and by the observance of the capacity
plates.
The values of the support force F are indicated in the table at paragraph "2.3 Technical
Data". Just as an indication it's enclosed the below table.
