PRELIMINARY
• The band saw Mod. 91, has been designed, manufactured and patented for
metal dry cutting (in stationary mode), on a table, with fixed head in vertical
position, or in a vise with swivel head, manual operation (especially for pipes with
a maximum diameter of 150 mm).
It is absolutely forbidden to use the machine to cut any containers formerly
used for flammable or toxic substances.
The Manufacturer declines all responsibility for any injury or damage -caused by
uses other than the intended ones, failure to comply with the instructions
provided or misinterpretation of the good use, maintenance and safety
precautions contained in the present manual.
NOTE
• It is absolutely forbidden to modify the machine safety equipments and/or
devices.
Before operating the machine, make sure its use does not create hazardous
situations.
• The Manufacturer declines all liability for modifications or interventions, use of
non-original parts or parts not complying with the Manufacturer's quality
standards. All the previous situations invalidate the warranty.
• Extraordinary maintenance operations must be carried out exclusively by
qualified personnel and authorized Technical Service Centers.
GENERAL PRECAUTIONS
•Always make sure in advance that the minimum safety, placement and
operating standards are respected, taking note of the environmental conditions,
temperature, humidity, lighting, vibrations, suspended dust and the
appropriateness of the area to be used.
The saw may operate outdoors (work sites, open spaces in general, etc.) or
indoors (workshops, laboratories, etc.) where there is no risk of explosion or fire.
Before using the equipment, make sure that the surface where the machine will
be placed is flat, sufficiently sturdy and ergonomicall: for this reason we
recommend using a the optional machine bed (A-F.1).
Always make sure in advance that the work-piece is tightly clamped; in any case,
make sure that the start of the production cycle does not create hazardous
situations for people and/or property.
Dispose of processing waste in compliance with current regulations

3. SECURITY DEVICES
3.1 SAFETY SWITCH
In order to start the engine, it is not enough to press the
"trigger" (A),
but first it is necessary to lower the safety switch (B) (orange).
3.2 VERTICAL HEAD POSITION SENSOR MICROSWITCH
• When the head is overturned in vertical position, the pin (C)
operates on the underlying microswitch which inhibits the
safety switch positioned on the handgrip (F. 1).

3.3 EMERGENCYPUSH-BUTTON (D)
• It works only when the head is in vertical position and operates
on the underlying stop push-button.
3.4 HEAD LOCKING
PIN
• The pin (E) guarantees the locking of the head in vertical position
and prevents any accidental overturning.
3.5 FIXED GUARDS
• The fixed guards (covers) are fitted to the machine by means
of screws. Only the service personnel is authorized to open
these guards after cutting out the power. After each
intervention, the guards must be fitted back.
It is absolutely forbidden
to operate the machine without the guards in place:
A - Piece locking vice cover.
B - Pulley protection cover.
C- Mobile blade guide protection cover.
D- Electrical cable protection cover.
3.6 SAFETY PRECAUTIONS
IT IS ABSOLUTELY FORBIDDEN:
• to lubricate the blade (saw);
• to work without the blade guide properly positioned and
locked;
•to work without the rear guard;
• to hold the piece to be cut by hand;
• to have a second person holding the piece;
• to use clamps, adhesive tape, iron wire, etc., to lock
in position the start button in order to operate in
"automatic" mode;
• to let people under age, with disabilities, dearly unable,
drug or alcohol addicted operate the machine;
• to work without safety glasses or eyes protections;
• to work with bracelets, ties, scarves, loose sleeves,
unbuttoned working coats or any loose cloth;
• to leave the machine unattended with the "head" lifted.
Always lower the blade head at the end of the
processing.

4. INSTALLATION
• Place the machine on an adequately sturdy workbench.
• A
Before connecting the plug (B), check that the power
voltage corresponds to the voltage indicated on the
machine plate and that the plant mains is equipped with a
safety circuit breaker.
ssemble the piece locking device (A).
5. OPERATING THE MACHINE
5.1 PRE-OPERATION ACTIONS FOR SWIVEL HEAD CUTTING
• Lift the motor-driven head at its top end of stroke and release it;
making sure it does not lowers spontaneously. If necessary, tighten
the screw (A) to adjusts
the friction force on the lifting group.
• Try ti lower and lift the head a few times, acting on the handle: the
head should be slightly "frictioned". If necessary, act again on the
screw (A) until the head slides properly.
•Loose the knob (B) and shifting the piece locking vice along the
cylindric guides (C).
• Lock the vice in the required position acting on the knob (B),
Note: the machine described in the present manual has been
designed to cut pieces both on the right and hand side of the vice.
• Fit the piece supporting devices (D) and lock them with the screws
(E).
5.1.1 SLOPE CUTTING
• Position the motor-driven head according to the slope cutting to be
made acting on the screw (F) using the graduated scale as a
reference.
• After sleeting the required position, firmly tighten the screw (F).
5.1.2 ADJUSTING THE MOBILE BLADE GUIDE
• Loosen the lever (G).
• Slide the blade guide (H) fitted on the protection
Note: In some models, the lever
(G) can be replaced by a screw.

Note: always keep to a minimum the protruding (I) part of the b
(saw) lade
d
• Once the part of the "no-protected" part of the blade has been
adjusted to assure a safe operation, tighten the lever (G) or the
screw, when present).
5.1.3 BLADEALLIGNMENT ADJUSTMENT
Note: In order to machine properly and accurately, the blade (I)
should be perfectly positioned at right angles, that is parallel to the
axes of the sliding rollers (L).
•In order to carry out the adjustment proceed as follows:
- Moderately loosen the two screws (M).
- Operate on the dowels (grub -screw) (N) until the blade is in
perfect vertical position.
- Tighten the screws (M).
5.1.4 ADJUSTMENT OF THE CLAMP
• Loose the knob (O).
• Slide the rode (P) according to the length of the piece to be cut
then lock the knob (O).
• Lock the piece to be cut by the vice against the piece locking ro
(P) and firmly tighten the lever (Q) of the vice.
5.2 SETTING THE CUTTING SPEED
• Set the blade speed according to the material to be cut, acting
on the adjusting device (R).
5.2.1 CUTTING SPEED
MATERIAL m/rnin.
Stainless steel 20-50
Copper, aluminum and its alloys 50-80
Steel, etc. 80+110
Plastic materials

5.3 OPERATOR POSITION
• The placement of the machine in relation to the operator position must make it possible to observe
the results of the operation and maintain safety conditions.
• During this stage, make sure the start button (A) and speed regulator (B)
are easily accessible, and that there is sufficient visibility and lighting on
the tool, the surrounding area and base.
It is strictly forbidden to place and/or use the saw when
environmental conditions constitute a
hazard of explosion or fire. It is forbidden to use the machine for any
purpose other than that intended by the manufacturer.
Make sure that operation of the saw does not create hazardous
situations for people and/or property.
Should you encounter a malfunction, stop the machine immediately
and check the reason for and/or extent of the breakdown. Contact
the authorized Technical Service if necessary, it is strictly forbidden
to exceed the cutting capacity stated by the manufacturer.
5.4 STARTING
Release the mechanical safety switch by turning the lock (orange) down (C), then press the button (D)
pressure.and begin cutting using even The first time it is started, the machine will be fairly noisy, due to
the normal breaking-in stage of the transmission gears. This noise
will disappear after approximately 8 machine hours; in any case,
the measurable noise level is equal to and not greater than 78 dbA.
• Do not run the machine without a piece to be cut for long periods.
• Do not cut "hardened" or "cemented" steel parts.
• Do not use blades not provided by the Manufacturer.
» Do not use blades extremely worn or with damaged teeth.
• Do not use lubricants or cooling liquids for tthe blade: the machine is a
designed for dry cutting.

Note: when the lever (A) reaches the end of its
stroke, the blade will automatically position itself for cutting when the motor begins to turn.
Replace the rearguard and the guard (D) of the mobile blade
guide.
During the first 4-6 cuts (after replacing the blade) use slight cutting
pressures, to increase the duration and effectiveness of the blade
thereafter.
