Remember that there should be a magnetothermic
protective device fitted upstream of the mains to protect
all the conductors from short circuits and overloads.
This protective device should be selected according to the
electrical features of the machine listed below:
Nominal voltage ............................................... 230 Volt ~
Nominal frequency ....................................... 50/60 Hertz
Max programmed absorbed value ................. 2,5 Ampere
Nominal input power .......................................... 850 Watt
Power factor .............................................................. 0,92
Nominal speed ............................... 10.000-23.000 Giri/m’
Insulation ........................................................... Classe B
Type of service .............................. intermittent S4-60 %
In case of power failure in mains, while you wait for
power to be restored there is no danger hazard may
arise: in fact, the electronic governor O or main switch
D is also equipped with a reset function which prevents
the machine from restarting automatically.
The motor of your sawing machine (electronic version)
is equipped with a protective heat circuit breaker which
interrupts the power supply when the temperature of
the coils rises too high.
When the power supply is interrupted, wait for normal
reset.

ADJUSTING (Fig. 4-5-6-7-8)
3.1
TENSION OF THE BLADE (Fig. 4)
Turn the handwheel
B
in a clockwise direction until it locks.
ATTENTION: If the tension is too high, the blade
tends to escape from the guide. In this case,
slacken the blade tension by turning of one/
two turns the handwheel
B
in a anti clockwise
direction.
3.2
BAR STOP (Fig. 5)
Use the bar stop supplied if you have to do several cuts
on pieces of the same length.
In this way you do not have to repeat the same
measurement each time.
Screw rod
E
into the hole of the base and fasten it with nuts
F
. Slacken the handwheel
G
and place the stop
L
at the
correct distance from the blade. Tighten handwheel
G
again.
3.3
CUTTING ANGLE (Fig. 6)
The band saw can cut at an angle varying from 0 to 45
degrees: it is sufficient to slacken the handle
I
and turn the
swiwel support
J
towards the respective limit stops
H
and
K
.
For all intermediate angles, turn the swiwel support
J
until
the mark
M
on the support matches the corresponding
position on the plate.
Then lock the rotating support
J
again.
3.4
CUTTING SPEED (Fig. 7)
Two speed version
Depending on the type of material and its section (see
CUTTING TABLE) you can choose two different cutting
speed 60 or 80 m/min. by means of the switch
N
.
Electronic version
Your sawing machine is equipped with CESC (Constant
Electronic Speed Control), which allows gradual and
continuous variation of the cutting speed, adapting it to the
type and dimension of the material to be cut (see cutting
table).
To select the most suitable speed, use the speed control
knob
O
to increase or decrease the speed as you require.
Example:
Stainless Steel:
30 m/min.
position 1
Common Steel:
40-60 m/min.
position 2-3-4
Allum. Alloy:
80 m/min.
position 6
Pipes/sections:
70-80 m/min.
position 5-6
3.5
SLIDING BLADE GUIDE (Fig. 8)
The sliding blade guide
P
with integrated protection fitted
on your sawing machine is used to perform the cut while
guiding the necessary part of the blade and fully protecting
the part not used in the cutting process.
Slacken the knobs
Q
and slide the blade guide
P
so as to
move it closer to or further from the part to be cut, as
shown in the figure.
ATTENTION: If this adjustment is not done, the
part of the blade not used in the cutting process
will be exposed and this will create an extra
risk of contact, besides altering the quality of
the cut.
3.6
BEARINGS BLADE GUIDE (Fig. 9)
The blade-guide on the outside of the sawing machine are
eccentric and adjustable so as to simplify blade replacement
and to keep it guided as its best.
They must always touch the blade slightly, so that they
rotate when the blade passes, but must not be completly
locked.
In order to approach or remove the eccentric blade-guide,
gently turn the head of the screws
S
using a 10 mm.
wrenches key.

4.1
RUNNING IN THE BLADE
ATTENTION: If the correct running in procedure
is not performed, the blade’s cutting precision
may be irreparably compromised.
To obtain the best performance, the bi-metal blades fitted
on your sawing machine must be run in for a short period.
For this reason the first two or three cuts should be done
where possible on a solid piece D.40-50 mm, using a very
slight pressure on the blade, and gradually increasing
pressure in subsequent cuts. To gauge the correct pressure
in normal operating conditions defined by this manual (see
cutting table), consider for example that the first cut on
solid steel (eg. C40) D.50 mm should be done in about 4
minutes.
