1.6 SAFETY PROCEDURE FOR FURTHER RISKS
– Do not force the machine unnecessarily: excessive
cutting pressure may lead to rapid deterioration of the

the clamps designed for this purpose: all workpieces
must be clamped down fi rmly.
– Avoid accidental starts: do not press the start button
while inserting the plug into the socket.
– Always use the tools recommended in this manual to

NOTE: When cutting aluminium the use of
protective earphones or ear plugs is absolutely
necessary. The use of this gear is also
recommended for all other uses.
1.8 INFORMATION ABOUT ELECTROMAGNETIC
COMPATIBILITY
The European regulations on safety and, in particular,
the 2004/108/EC contemplate that all the equipment be

1.9 MACHINE DESCRIPTION (Fig. 1)
The mitre-saw machine consists of three basic parts : the
machine body complete with motor 6 which is integrated into
lower part 3 by means of the joint 4 and the swivel support
5, and the upper work unit consisting of the work table 15,
the rest square 17 and the movable blade cover 16.
The base 3 is used as rest when cutting and butting
operations have to be carried out in the different available
angles; the upper table is used as rest when trimming
or sectioning wood tables of huge dimensions and, in
particular, when cutting wood along grain.
