In case of an electric black- out, as well as on machine turning off, the hydraulic pump stops completely in 40 seconds approx. and the
rotating arm begins its slow descent (Fig. 18). Therefore it is necessary that in such events the operator takes care not toleave anypart
of his body or any other object between the cutting table and the turning arm.

Device activation:
1) Lower the switch lever, placed on the electrical equipment box, to the Cutting Emergency position (Fig. 19).
In case of clicking presses equipped with a single potentiometer (SE Series):
2)Resetthepotentiometerand,afterhavingplacedthecuttingdieonthemachinecuttingtablewithoutanymaterial inbetween, bymeans ofthe
turning arm adjustment wheel place the turning arm at 15 ÷ 20 mm from the cutting die.

In case of clicking presses equipped with the three- push- button- unit and two potentiometers (S100 Series):
4) Reset thevalues ofboth potentiometersand, afterhaving positionedthe dieon themachine cuttingtable withoutany materialin between,by

For a good machine efficiency it is advisable to carry out the following maintenance operations periodically:
a) turn upside--down the cutting pad (for S/SE108: code 02001164; for S/SE116: code 02001209; for S/SE120C: code 02001185; for
S/SE120/124C/125C: code 02002625; for S124/125/125L: code 02001186; for S122: code02001563, tav.1) everyweek andplane itwhenever
there are wears or sinkings of approx. 2 mm;
