1.2 Machine plate
Important data can be found on the following plate located on the machine:
1.3 Safety instructions for particular operating phases
The machine has residual risks that cannot realistically be eliminated by the manufacturer. Guards
cannot prevent access to the blade when cutting, not even if pushers or other safety tools are used.
Machine users must consequently keep in mind that sawing machines are among the most
dangerous of machines.
The machine must always be used with intelligence and good sense, adopting
all the precautions contained in this booklet.
CAUTION !!! RESIDUAL RISKS
In band saws access to the blade is always possible, even if the vertical blade
guard is properly adjusted and clamped in place 5mm above the piece to be cut.
The band blade is protected against accidental contacts during its entire length except for the
section that is strictly necessary to make the cut.
Therefore it is absolutely necessary:
When making cuts keep your hands away from the blade.
Always use a pusher to finish the cut.
Use special tools when pieces to be cut have uneven shapes:

(For example: for pieces which do not have a good support surface create
supports that house the piece to be cut).
Totally lower the blade guard at the end of work.
If the band breaks, even if the stop control is engaged, the upper flywheel is not braked.
To avoid all risks always wait until the flywheel is completely stopped.
It is always recommended to properly put the machine in place to increase its solidity and prevent
useless and damaging vibrations, even though the machine is rigid and massive and offers the
utmost guarantee in terms of solidity and sturdiness. The manufacturer is released from all
responsibility for any damage caused by negligence.
1.4 Safety regulations
1) Before connecting to electric mains make sure there is adequate protection upstream on the line
complete with circuit breaker, earth-leakage switch and a ground conductor.
2) Check that the voltage and frequency indicated on the name-plate correspond to mains voltage
and frequency.
3) Do not use non-standard or defective cables, extensions or plugs.
4) Make sure work is always done in safe conditions.
5) Always start to work with the machine firmly positioned.
6) Wear protective gloves, heavy-duty or safety shoes, work goggles and personal protection
devices to protect hearing.
7) Do not use the tool in the rain or expose it to the rain.
8) Correctly position the cable during work. Make sure it is distant from the work area and is long
enough to permit work to be done properly.
9) Always cut off from the mains connection when performing maintenance.
10) The machine must only be used by adult and qualified persons.
11) Comply scrupulously with the instructions affixed on the machine when working.

The vibration value is lower and does not exceed 2.5 m / s.
The measurements are made with new machines. Actual values may vary with site conditions, in
terms of:
Materials worked
Wear Machine
Lack of maintenance
Inappropriate tool for application
Tool in poor condition
Unskilled operator
Etc…
The exposure time to vibration is based on the performance of work (related to the adequacy
Machine / Tool / worked material / operator)
When evaluating risks due to hand-arm vibration, you need to take into account effective usage at
rated power of machine during a full day of work; quite often you will realise that effective utilisation
time represents around 50% of overall duration of work. You have to consider, of course, breaks,
water feeding, preparation of work, time to move the machine, disk mounting…

4 TRANSPORT
4.1 Security
The machine, given its exceptionally sturdy, can be easily shipped without requiring any
disassembly operation: however it is important to keep to the following precautions:
Make sure that hoisting or anchor cables do not rest on fragile parts, on protective covers or on
tubes that protect the electrical system;
For fixing the machine with strap or rope use exclusively through the appropriate place on the
frame (Fig.5);
Avoid sudden blows or jolts both during hoisting and when setting the structure back down;
During long trips on roads which are not particularly straight it is very important to firmly anchor
the structure to the transport vehicle to prevent accidents caused by speed during curves,
bumps or slopes;
All machines have special holes or hooks for hoisting. Please use these insofar as possible to
avoid the problems specified above.
4.2 Hoisting
The machine can be hoisted using a special hoisting hook. Use a standard market hoisting hook
connected to a chain or cable with a minimum hoisting capacity of 300 Kg. (fig.5).
The machine can also be hoisted by a lift truck, introducing the forks below the base of the
