Note: In case the saw is not used for a period of time, release

the blade tension to avoid useless stress.

The band saw is now ready to start work, bearing in mind that
the CUTTING SPEED and the TYPE of BLADE - combined with
a suitable descent of the head - are of decisive importance for
cutting quality and for machine performance (for further details
on this topic, see below in the chapter on “Material classifica-
tion and blade selection”).
- When starting to cut with a new blade, in order to safe-

guard its life and efficiency, the first two or three cuts
must be made while exerting a slight pressure on the part,
so that the time taken to cut is about double the normal
time (see below in the chapter on “Material classification
and blade selection” in the section on

Blade running-in).

- Press the red emergency button ( 1 ) when there are condi-

tions of danger or malfunctions in general, so as to stop ma-
chine operation immediately.

- Once you selected the function mode ( see paragraph 6.1 ),

place the piece to be cut inside the vice by moving jaw to
about 3 - 4 mm and lock with lever ( 8 ).

- Reach for handgrip ( 7 ) of the SAW FRAME control lever,

strike the push-button and check that the blade is turning in
the direction indicated ( if not, invert the two phase leads);

- Make sure that the cooling liquid flows regularly.

REGULATING
THE MACHINE

7.1 - Blade tension assembly

The ideal tension of the blade is achieved rotating the handwheel
until it stops against the microswitch button ( A ).
WARNING: the projection of the microswitch is factory set during
inspection, after having tightened the blade on the lengthening
values indicated by its manufacturer as per specific dimensions
set with the help of a special gauge. If, when replacing the blade,
the thickness and the width differ, it will be necessary to correct
the projection of the microswitch. For this purpose we suggest
to strictly select blades having the same features as the ones
mounted originally.

7.2 - Blade guide blocks

The blade is guided by means of adjustable pads set in place
during inspection as per the thickness of the blade with mini-
mum play as shown in the figure.
