—    workpiece vacuum clamping as part of a front side turn table or of a panel loading device;
—    panel pusher;
—    independent panel pushers;
—    additional panel pushers mounted on the panel pusher carriage;
—    additional panel pusher with integrated label printer device;

—    device for automatic loading of thin panels;
—    device for base board unloading by gravity;
—    device for base board powered unloading;
—    device for panel unloading in limited space condition;
—    loading or pre-loading roller conveyors;
—    pressure beam with additional flaps to increase dust extraction efficiency;
—    saw blade cooling system by air or water-air or oil-air;
—    vibrating conveyor with/without trimming unit for offcuts management;
—    predisposition for top loading/unloading by an external system directly on the machine table and/or on the machine preloading roller conveyor and/or on the machine lifting table.
NOTE      base board is a support panel underlying the panel stack, to protect the panels from damages during transportation.
The machines are designed for cutting panels consisting of:
a) solid wood;
b) material with similar physical characteristics to wood (see ISO19085‑1:2021, 2);
c) gypsum boards, gypsum bounded fibreboards;
d) composite materials, with core consisting of e.g. polyurethane or mineral material, laminated with light alloy;
e) cardboard;
f) foam board;
g) matrix engineered mineral boards, silicate boards;
h) polymer‐matrix composite materials and reinforced thermoplastic/thermoset/elastomeric materials;
i) aluminium light alloy plates with a maximum thickness of 10 mm;
j) composite boards made from the materials listed above.
This document does not deal with hazards related to:
—    specific features different from those listed above;
—    the machining of panels with milling tools for grooving;
—    powered unloading of panels;
—    rear half of split pressure beam on the front cutting line;
—    the combination of a single machine being used with any other machine (as part of a line).
It is not applicable to:
—    machines intended for use in potentiall
