Case of use 1.2: Fortuitous contact with the disk
when turning without load in the resting position
Description of an accident of type 1.2.1: It occurs
when working with a machine that has been
manipulated or lacking guards. Under these
conditions the actuating element remains locked
such that the operator maintains the disk rotating
without load in the resting position and with the disk
being accessible. At the same time the operator's
hand enters into contact with the cutting disk whilst
carrying out operations in areas in the vicinity of the
disk (e.g. removing the cut workpiece, placing a
new workpiece on the table, etc.)
Case of use 1.3: Abrupt fall if the disk due to
breakage of the fastening spring in the resting
position
Description of an accident of type 1.3.1: There
occurs the drop of the counterweight of the movable
head sustaining the cutting disk due to breakage of
one or both of the counterweight springs or of the
anchoring thereof. At the same time the disk
remains rotating without load. At the same time the
operator has his/her hands under the cutting path.
Under these conditions the disk catches up with the
operator's hands that at that moment are carrying
out operations in that area.
2.Projection of the cut workpiece
Case of use 2.1: Abrupt fall if the disk due to
breakage of the fastening spring in the resting
position
Description of an accident of type 2.1: This risk
appears when operating on short workpieces with
fixed stoppers. After completing the cut and raising
the disk, the remnant wedged between the stopper
and the disk may be dragged thereby and projected
violently, and in the worst case even lead to a
breakage of the disk.

machine-specific risks
1.Preventing contacts with the cutting disk
1.1 Prevention during the development of the
cutting operation
1.The operator must mandatorily be sufficiently
trained and instructed, and know the present
manual in such a manner that he/she is able to
know if a machine or his/her working environment
are suspicious of not providing a perfect service.
Do not use the machine under these
circumstances!
2.Revise any lack of guards or any other
component of the machine. Never use a machine
that is not complete, not in a perfect condition and
not correctly installed. If the machine has been
manipulated, lacks pieces or is in a bad condition,
disconnect it, remove it from the working area, do
not use it and send it to the technical service.
3.Never put your hands or any other part of the body
nor garment upon or below the cutting area of the
ENGLISH
36
disk or within the cutting path of the disk.
4.Fastening the workpiece to be cut shall not be
carried out manually but with the assistance of
pushers, wedgers and clamps warranting a firm
fastening of the workpiece to be cut under any
circumstances (appearance of nods, etc.). By
putting this preventive measure into practice the
risk of contact with the disks during the
development of the operation is practically
excluded as it allows hands to remain distanced
from the hazardous area.
5.Always disconnect the machine when leaving it
alone.
6.The presence of one or more assistants will be
required for cutting workpieces being longer than
1.5 m.
1.2 Preventing fortuitous contacts with the disk
rotating without load in the resting position
Independently from that the disk, when resting,
stays protected by the safety guards as installed, it
is categorically advised against using the locking
switch so as to guarantee that disk does not rotate
without load in the resting position thereof.
1.3 Preventing abrupt falls of the disk due to
breakage of the spring
1.By means of a regular maintenance the machine
will always be in a perfect condition.
2.Check the area and the machine on each working
day and routinely test all movements visually with
the machine disconnected.
3.Check springs 32 and the bearings thereof on
each working, and have them checked
periodically by qualified personnel.
4.Make sure that the head perfectly ascends to its
upper position by the sole action of springs 32.
5.Check the upper locking system on each working
day by raising the head up to abutment and
checking locking and unlocking by means of
button 29, and have this periodically checked by
qualified personnel.
6.Never expose your hands or any other part of your
body to he cutting path.
7.Never allow the head that holds the disk to remain
in an undetermined position unless the operator
is mandatorily grasping the control grip 4.
8.For any break between cuttings, however short it
may be, always use the automatic lock of the
head in the upper position by raising the head to
the upper stopper.
9.Each time that the machine remains at rest, leave
it in the lower resting position by placing the head
at 90º vertical and 0º horizontal, protecting by
means of the stationary guard 34 and finally
locking it by lowering the head and pushing
button 30.
2.Preventing projections of the cut
workpiece
So as to carry out the cutting of workpieces using a
stopper, this latter must be foldable or movable.
Once the operator has selected the cutting range
and firmly fixed the workpiece to the table, he/she
