according to the most advanced technologies and may be
used for all cutting requirements for metals commonly
used in industry and artisanship.

It can cut:
.COMMON STEELS (FE 37…)
.SPECLAL STEELS (C 40, 18NiCrMo5…)
.ALUMINIUM AND ITS ALLOYS
.BRASS
.BRONZE
.STEEL TUBING (FE 35, FE 52…)
.PROFILED SECTIONS IN SHEET METAL AND
ALUMINIUM
It is not suitable for cutting:

-WOOD AND SIMILAR MATERALS

-BONE AND SIMILAR MATERIALS

ATTENTION:The band saw has been developed and
manufactured to cut in dry condition; the use of any
cooler by lubricating oil makes the machine unusable.

Consult the relative sections for cutting capacities, the
speeds to use and the type of tools for use according to
the material to be cut and its section.(See list of contents).

1.4 STANDARD SAFEY PROCEDURS

-Do not use the machine in very damp places or in the
presence of inflammable liquids or gases.

-Do not use it in the open air when general weather and
environmental conditions are unfavourable (eg.
Explosive atmospheres, during a storm or rain).

-Wear suitable clothes, without wide sleeves or articles
such as scarves, chains and bracelets which could get
caught in the moving parts.

-Always use personal protection devices: protective
goggles as recommended by safety standards, gloves of
the right size, headphones or earplugs, and hairnets if
necessary.

-Use the tools recommended in this manual if you want to
achieve the best performance from your sawing
machine.

-Any power cable extensions must be type approved and
comply with safety standards.

-Avoid using the machine if your psycho-physical condition
are precarious or upset.

1.5 SAFETY PROCEDURS FOR FURTHER RISK

-Always keep processing residues away from the cutting
area.

-Always use the clamp. The parts to be cut must always
be held firmly in the clamp.

-Always keep hands away from the working areas while
the machine is moving: before loading or unlading the
part, release the run button on the hand grip.

-Do not force the machine unnecessarily : excessive

cutting pressure could cause rapid wear to the blade
and negatively influence the performance of the
machine in terms of finishes and cutting precision.

1.6 NOISE CONDITIONS

In normal conditions of use as described in this manual,
this belt sawing machine determines an equivalent level of
acoustic pressure:
Leq= 82dB(A) when operating unloaded;
Leq= 84.3 dB(A) during processing (eg. cutting of a steel
tube D.80mm thickness 5mm), at cutting speed of
80m/min., with a weighted operating cycle of 1 minute.

Measurement were obtained in compliance with UNI
7712, ISO 3740,ISO 3746 and CEE 89/392 regulation.

2.0 INSTALLAZIONE

2.1 REMOVING THE PACKING

Remove the wooden frame which protects the
machine during transit.

3

Try not to damage the frame as you may have to move
the machine long distances or store it for long
periods.

2.2 HANDLING (Fig.2)

As the machine is not heavy (Kg 16), it can be
lifted and moved by a single person by gripping it
from the machine body (5), duly clamped (see pint 2.3)

2.3 TRANSPORT (Fig.2)

It is necessary to low the saw body till the lower position
and fix it to the base : it is sufficient to insert the pin U in
the hole in the body , then lift the machine, gripping it as
showed in Fig.2.
For transport the machine, it is better to place it in the box
it was when purchased.
Ensure it is placed in the correct position indicated by the
arrows on the packaging.
Pay careful attention to the ideogram printed on the box as
they provide all necessary information for palletization and
stacking of boxes.
Tying the load down with ropes or safety belts is
raccomended during transportation to prevent the load
from sliding or falling.

2.4 POSITION/WORK STATION (Fig.3)

Place the machine on a sufficiently flat workbench so that
the machine has the better possible stability.
In respect of ergonomic criteria during cutting operations,
the workbench must be positioned at such a height that
the clamp level is between 90 and 95 cm from the ground
(see fig.3)

ATTENTION: Make sure that the machine is placed in a
working area with suitable environmental conditions
and lighting. The general conditions of the working
environment are of fundamental importance for
accident prevention.

2.5 ELECTRICAL CONNECTIONS

Check that the mains to which the machine is connected is
earthed in accordance with current safety regulations and
that the power point is in good condition.
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.................................1~,115 / 230V

Nominal frequency.............................50/60Hertz

Max programmed absorbed value .....3.8Ampere

Nominal input power..........................1250Watt

Power factor.......................................0.93

Nominal speed .................................14.000-19.000rpm

Insulation ...........................................Class 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 face,
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.

3.0 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.

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
CUTTINGTABLE) 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: 30m/min. position 1
Common Steel: 40-60m/min. position 2-3-4
Allum.Alloy: 80m/min. position 6
Pipes/sections: 70-80m/min position 5-6
