1.4 - Machine description
The bone saw you have purchased is a safe and reliable machine that is simple to
use. The pulleys are in aluminum while its body and accessories are in stainless
steel type AISI 304. The bone saw has guards installed that are both mechanical
(housing, doors, etc.) and electrical (micro-switch, stop button, etc.), which are
meant to reduce the operator’s exposure to risks during its use to a bare minimum.
The tilting angle of the pulley can be horizontally and vertically adjusted, so as to
always ensure maximum blade adhesion. The engine is ventilated and well-
protected against water and intermittent operation. The control panel is installed in
an easily accessible position and features 24V control buttons. Special care has
been given to facilitate cleaning tasks when designing the machine, thanks in par-
ticular to the following technical measures:
- simple removal of the blade and upper pulley without the need for tools,
- Once the pulley is removed, the machine’s surface is smooth, making it easier to
clean and allowing dirt on the blade to directly deposit in its tray.
- all its electrical parts have been manufactured to provide the minimum safety
standard IP 56.
1.5 - Intended use
The bone saw has been designed and manufactured to cut bone and frozen fresh
meat and fish. Use the bone saw only on top of a table or on the stand supplied by
the manufacturer. Given its use to saw foodstuffs, the materials used to manufac-
ture the blade and all other components that may make contact with the cut prod-
uct have been carefully selected. The bone saw is an industrial appliance and only
skilled professionals should use the machine, after having carefully read this man-
ual. This equipment complies with the essential health and safety requirements of
directive 2006/42 / EC and the requirements of directives 2014/30/EU, 2014/35/
EU, 2006/42/EC, RoHs 2011/65/EU and Regulation 1935/2004/EC. The machine
was designed and built according to the requirements of EN 12268: 2014.
Since it is also suitable to cut frozen fish, the bone saw does not require special
environmental conditions. We nonetheless advi se you to store it away indoors,
protected against bad weather and abrupt temperature changes.
1.6 - Improper use
The bone saw must only be used as instructed by the manufacturer; more specifi-
cally:
- Do not use the machine if has not been correctly installed with all guards intact
and properly assembled, so as to avoid the risk of personal injury.
- Do not use the machine with a worn or unsharpened blade, as it may break.
- Do not climb with your feet onto the machine, even if is off, as this could dam-
age the machine, besides the risk for the operator of falling.
- Do not access the electrical components without having first cut off power to the
machine: danger: risk of electrocution.
- Do not use the machine to cut anything other than meat, bone or fish.
- Do not stop the blade with your hands, but wait for it stop of its own, so as to
avoid the risk of severe personal injury.
- Do not wear rings, wrist-watches, jewelry, loose or draping clothing, like shoes,
neckties, torn apparel, unbuttoned jackets our blouses with an open zipper,
which may get stuck in moving parts. Use approved safety clothing like non-slip
boots, safety goggles, work gloves, ear muffs or plugs, safety mask. Consult the
employer concerning the applicable safety regulations and the required personal
protective equipment.

that any hazardous and potentially threatening condition has been thoroughly
eliminated. If you notice any abnormal condition, stop the machine and immedi-
ately inform staff in charge of maintenance.
- Do not allow unauthorized personnel to perform tasks on the machine. The
emergency procedure to follow, should the machine operator suffer an accident
involving electrically conductive parts, is to first of all pull the operator away from
the power source (since usually the operator loses consciousness in this type of
accident). In this case, the operator is a live conductor: touching him would
mean suffering electrocution. Proceed to disconnect the contacts from the power
line valve or, if this is not possible, draw the victim away with the aid of insulating
materials (wooden clubs or PVC, fabric, leather, etc.,). It is advisable to immedi-
ately request medical staff to intervene and have the patient hospitalized.
- Do not perform any task on the machine if not duly authorized beforehand.
- Follow the procedures established for maintenance and technical assistance.

3.1 - Testing
The machine you have purchased has been tested at our facilities to ensure that it
works properly and is properly adjusted. Trial sawing drills have also been per-
formed as part of the tests, on the same type of material for which the machine is
normally used to cut.
3.2 - Machine delivery and handling
All the shipped materials have been accurately checked before they were handed
over to the courier.
Unless otherwise agreed with the customer or
in the event of especially costly transporta-
tion, the machine is packaged on a wooden
pallet protected by strapped cardboard. The
dimensions of the packing are shown in Pic-
ture 3.2.1.
Check that the packing is intact when you first
receive the machine.
If the packing happens to be torn or in any
way damaged, sign the delivery note includ-
ing the wording: “accepted with reserv ations” and the reason for the note.
Once you have opened the package, if certain machine components display evi-
dent damage, notify the courier thereof within three days from the date on the de-
livery note.

6 Using the bone saw
6.1 - Regulations
CAUTION Only authorized staff can operate the machine.
Before using the bone saw, the operator must check that all its guards are in place
and that the safety devices are installed and efficient. If they are not, turn the
machine off and contact staff in charge of maintenance. Have maneuvers with the f
machine empty only performed with the aid of specialized personnel, in order to
familiarize with the machine enough to use it safely.
6.2 - Preiliminary adjustmets (Pic. 6.2.1)
Scoop “2” must be adjusted based on the size of the
cut product.
- To adjust scoop “2”, loosen knob “1”, then move the
scoop to the desired distance from the cutting
blade, which will define the cutting width.
- Tiighten knob “1”.
- adjust the sliding blade protection (3) according to
the height of the piece to be cut, so as to leave
uncovered only the part of the blade involved in the
cutting.
6.3 - Using the bone saw
Perform the adjustments as described in par. 6.2.
The machine is now ready for use.
- Lay the piece you intend to cut “3” on the workbench, up
against scoop “1”
- Start the machine
- Using one hand, grab the pusher knob “2” and with the
other hand, guide the product while pushing it toward the
blade to cut it. When you have reached the last slice,
push the product toward the blade, using only pusher “2”,
without guiding the product with your hands.
IT IS FORBIDDEN TO SAW PRODUCTS THAN ARE SMALLER THAN 50 mm
6.4 Using the sliding surface of the meat grinder (optional)
The manufacturer can on request supply a stainless steel AISI 304 sliding surface
“2” to install on the fixed surface, which is very useful to cut meat.
By laying the piece of meat on the sliding surface and pushing toward the blade
with the aid of side board “1” (Picture 6.4. 1), you will considerably reduce the pres-
sure exerted by the meat on the workbench.
This will facilitate meat cutting tasks and
ensures the operator’s safety. If you wish to
use the sliding surface, simply turn it over.

Moreover, be sure to leave a wide space around the machine when laying it onto
the surface, considering the dimensions indicated in Picture 2.4.1. The space will
help operators to perform maneuvers more easily and will facilitate access to the
machine for service tasks.
Provide suitable lighting around the ma chine for operators who use the bone saw
to have clear sight of the machine and its surrounding
space.
The packing must be handled with the aid of a forklift or
other similar machinery, since the machine is supplied on a
pallet protected with cardboard (Pic. 3.2.1).
- Remove the 2 straps that hol d the cardboard fastened to
the pallet.
- Remove the two straps that hold the bone saw fastened
to the pallet.
- Remove the cellophane wrapped around the machine and
all other packaging material.

paragraph).
5 Start-up and stop
5.1 Checking the electrical connection
- Turn the differential circuit breaker installed upstream
of the machine to position “I”.
- The indicator light “2” must be on.
- Press start button “1” and stop button “3” right after it in
sequence, checking the direction of blade rotation.
The blade must rotate in the direction pointed to by
arrow “4” in Picture 5.1.1, i.e. toward the workbench.
If the blade is rotating in opposite direction, switch the circuit
breaker off by turning it to “0”. This will cut off power supply to
the machine.
Invert a power wire in the plug and repeat the above proce-
dure to check the electrical connection (par. 5.1).
Note:
In machines hooked to a single-phase line and accordingly configured, the direc-
tion of blade rotation is directly established by the manufacturer.
