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.

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 enbloc structure, 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 (Pic.1a);
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. (Pic. 1a).
The machine can also be hoisted by a lift truck, introducing the forks below the base of the
machine (Pic. 1b).
4.3 Moving small movements
Pull the drawbar all the way out (Pic. 2). Slightly lift the machine and push it in the desired direction.

VERS.2017.11.21 CB511_CB 651_MAN_EN
19
4.4 Stockage
The storage site must be clean, dry and at a constant temperature.
If the machine is not going to be used for a long period, please take the following measures:
Completely clean the machine
Incline the plate
To reduce its bulk the machine is generally delivered with the table inclined. To put the table in its
working position you must loosen the hex screw that blocks it, located below the table (Pic.3a pos.
A). Then lower the table and re-tighten the hex screw. Release the lever (Pic. 3b - pos.1) located
below the table, to free lengthwise travel.
Machine storage environment conditions are for temperatures between -15° and + 45°C. Avoid
corrosive environments (brine or acid).

5 OPERATING THE MACHINE
5.1 Positioning the machine
(Pic.4) An at least 1.5 meter space must be left around the machine for passage of persons and
property without the danger of blows and to permit normal maintenance procedures.
Any area inside and/or in the vicinity of a machine where the presence of an exposed person is a
risk for his health and safety is to be considered a dangerous area.
Any person who is located totally or partly inside a dangerous area is to be considered an exposed
person.
The person(s) charged with installing, operating, adjusting, maintaining, cleaning, repairing and
transporting a machine is to be considered an operator.
Before positioning the machine check that the floor is perfectly flat without slopes or impediments
that could jeopardize the perfect stability of the machine.
Also check that the load-bearing capacity of the floor is compatible with the weight of the machine.
5.2 Illumination
Machines are not equipped with illumination systems and consequently must be used in adequately
illuminated work sites. It is prohibited to use the machine when the operator does not have a perfect
view of the cutting line.
