7.1 - Blade tension assembly
The ideal tension of the blade is achieved rotating the handwheel
until it the microswitch, that actuates the operation of the machine
, is actuated.
WARNING: the position of this switch is factory set during in-
spection, after having tightened the blade on the lengthening
values indicated by its manufacturer as per specific dimensions
set with the help of a special instrument. If, when replacing the
blade, the thickness and the width differ, it will be necessary to
correct the projection of the switch. For this purpose we suggest
to strictly select blades having the same features as mounted
originally.

- Once you selected the function mode ( see paragraph 6.1 ),
place the piece to be cut inside the vice ( 9 ) by moving jaw to
about 3 - 4 mm and lock with lever ( 10 ).
- 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.
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 de-
tails on this topic, see below in the chapter on “Material classi-
fication 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 when there are conditions
of danger or malfunctions in general, so as to stop machine
operation immediately.

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.

Blade thickness should always be 0.9mm only. In fact, the blade-
guide pads have been especially adjusted for that very
thickness. Different blade thickness requires a re-adjustment
of the pads as follows:
- Use spanners (1=5mm), (2=4mm) and (3=12mm) to release
the screws and the nuts as shown here.
