1 Operation
1.1Safety rules for stationary power tools.
Follow them to achieve best results and full benefit from your new machine
The very good craftsman respects the tools with
which he works. He knows they represent years
of constantly improved design. He also knows
that they are dangerous if misused.
This is the theme of a new safe-use program for
stationary power tools. The safety rules are
based on approved practices in industrial and
home shops.
1. Know your power tool. Read
the owner’s manual carefully.
Learn its applications and
limitations, as well as the
specific potential hazards
peculiar to this tool.
2. Keep guard in place
and in working order.
3. Ground all tools. If tool is equipped
with three-prong plug, it should be
plugged into a three-hole electrical
receptacle. If an adapter is used to
accomodate a two-prong receptacle,
the adapter wire must be attached to
a known ground. Never remove the
third prong.
4. Remove adjusting keys
and wrenches. Form habit of
checking to see that keys
and adjusting wrenches is
removed before turning it on.
5. Keep work area clean.
Cluttered areas and benches
invite accidents.
6. Avoid dangerous
environment. Don’t use
power tools in damp or wet
locations or expose them to
rain. Keep your work area
well lighted.
7. Keep children away. All
visitors should be kept in a
safe distance from work
area.
8. Make workshop kidproof with
padlocks, master switches, or by
removing starter keys.

6
17. Reduce the risk of
unintentional starting. Make sure
switch is in off position before
plugging in.
9. Don’t force tool. It will do the job
better and be safer at the rate for
which it was designed.
10. Use right tool. Don’t force
tool or attachment to do a job it
was not designed for.
11. Wear proper apparel. Wear no
loose clothing, gloves, neckties,
rings, bracelets, or other jewelry
which may get caught in moving
parts. Non-slip footwear is
recommended. Wear protective
hair covering to contain long hair.
12. Always use safety
glasses. Also use face or
dust mask if cutting
operation is dusty. Everyday
eyeglasses only have impact
resistant lenses. They are
NOT safety glasses.
13. Secure works. Use clamps
or vise to hold works, when
pratical. It’s safer than using
your hands and it frees both
hands to operate tool.
14. Don’t overreach. Keep proper
footing and balance at all times.
16. Disconnect tools before servicing and when
changing accessories such as grinding wheels,
polishing mops, grinding belts, blades, bits,
cutters, etc.
18. Use recommended accessories.
Consult owner’s manual for
recommended accessories. Use of
improper accessories may cause risk
of injury to persons.
15. Maintain tools with
care. Keep tools sharp and
clean for best and safest
performance. Follow
instructions for lubricating
and changing accessories.

1.2 WARNING!
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California to
cause cancer, birth defects or other reprodrctive harm. Some examples of
these chemical are:
· Lead from lead-based paints.
· Crystalline silica from bricks, cement and other masonry products.
· Arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: Work in a well
ventilated area, and word with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.

3 INSTALLAZONE
3.1 REMOVING THE PACKING
Remove the wooden frame which protects the machine during transit
Try not to damage the frame as you may have to move the machine long distances or
store it for long periods.
3.2HANDLING (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)
3.3TRANSPORT (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.

12
3.4 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)
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.
3.5 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 itted upstream of the
mains to protect all the conductors from short circuits and overioads.
This protective device should be selected according to the electrical features of the
machine listed below:
Nominal voltage................................. 230Volti
Nominal frequency ............................ 50/60Herlz
Max programmed absorbed value.... .2.5Ampere
Nominal input power.......................... 850Watt
Power factor ................................. .... 0.92
Nominal speed ............................ ..... 10.000-23.OOOrpm
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 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 rlses
too high.
When the power supply is interrupted, wait for normal reset.
4 ADJUSTING (Fig. 4-5-6-7-8)
4.1 TENSION OF TME 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.
4.2 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.

13
4.3 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 Iock the rotating support J again.
4.4 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: 30mlmin. position 1
Common Steel: 40-60m/min. position 2-3-4
AlIum. Alloy: 80m/min. position 6
Pipes/sections: 70-80m/min position 5-6
4.5SLIDING 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, a5 shown in the figure.
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.
4.6 BEARINGS BLADE GUIDE (Fig.9)
The blade-auide 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 completely 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.

14
5 USE
5.1 RUNING IN THE BLADE
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 (eq. C40) D.50 mm
should be done in about 4 minutes. After running-in , the same piece may easily be cut in
about 2 minutes. If the running-in process is done correctly, the finish and precision of the
cut will be of better quality and the blade will last longer.
5.2 WORKING(Flg.7)
Two speed version
Push the green button "1"of the main switch D to anable machine operation.
Electronic version
Turn the main switch D to position 1 :in doing the switch comes on and the machine is
ready for operation. Before starting any cutting operation, check that all the protections
are complete and in the correct position.
Once you have completed all the procedures and operations described so far, you may
start the working processes.
To perform the cut, move to the front of the machine and grip the handgrip with your right
hand.
Keep your left hand away from the cutting area and on no account try to reach it when
cutting Is In process. Using the index finger of your right hand, press the run button A
(Fig.4) and gradually lower the machine body until it comes lightly into contact with the
part to be cut. Now begin to apply gradual pressure on the part and compete the cut.
Always release button A between one cutting operation and another, while you are
positioning the part. Do not try to block it or alter its functional
characteristics in any way.
Electronic version
If the machine suddenly stops after numerous consecutive cuts, do not be alarmed. The
heat protector device of the motor has been activated, breaking the power supply when
the temperature of the coils reaches the threshold limit defined by the insulation class, to
prevent damage to the motor.
In this case, release the button A and wait for automatic reset which usually takes place
after a few minutes,
Your sawing machine is equipped with an electronic speed governor which also includes a
motor protection function obtained by means of an amperometric limiter, In this way it can
not absorb an amount of current greater than the set one, expressed by the maximum
value of absorption (see 2.5).
If the limiter trips while the machirl8 Is in operation, slighty decrease the cutting pressure
in addition, this enables to safeguard the blade life and performance and to obtain .aIways
a sharp and clean cut.

15
5.3 replacing the blade (Fig.9)
When you perform the operation, always wear protective glovesto avoid contact with the
teeth of the blade.
-check that the main switch D is at position O;
-slacken the handle Q and slide the blade guide P as far as it will go, following the
direction on the arrow (Fig.8);
-remove the protective casing unscrewing the four screws;
-slacken the blade tension, turning the handwheel B in a anti-clockwise direction;
-using a 10mm. Spanner, slacken the exagonal nuts R on the two blade guides on the
outside of the blade (Fig.9); -with the same spanner gently turn the head of the screws
on the same blade-guide in a anti-clockwise direction so as to move the bearinqs far
enogh away from the blade to enable you to extract it easily from the guides ;
-extract the blade first from the guides and then from the rubber coated pulleys;
-insert the new blade first between the guides and then onto the rubber coated pulleys,
with the teeth facing as showed in picture 9;
-put the blade under tension again as described in point
3.1 and reposition the two outer blade guides in slight contact with the blade, tuming the
head of the screws S
in a clockwise direction;
-lock the two exagonal nuts R again;
-replace the protective casing, being careful to insert the blade between the straps of the
protection T;
-reposition the blade guides Pin the correct position for the next cut.
