electrical voltage and currents,
a circulating saw belt.
We have used construction resources and safety techniques to minimize the health risk to
personnel resulting from these hazards.
If the metal band saw is used and maintained by personnel who are not duly qualified, there
may be a risk resulting from incorrect or unsuitable maintenance of the metal band saw.
INFORMATION
Everyone involved in the assembly, commissioning, operation and maintenance must
be duly qualified,
and strictly follow these operating instructions.
In the event of improper use
there may be a risk to personnel,
the metal band saw and further property might be endangered,
the correct function of the metal band saw may be affected.
Always disconnect the metal band saw from the electrical power supply when performing
cleaning or maintenance works.
WARNING!
The metal band saw may only be used with the safety devices activated.
Disconnect the metal band saw immediately whenever you detect a failure in the safety
devices or when they are not mounted!
All additional devices installed by the operator have to be equipped with the prescribed
safety devices. This is your responsibility being the operating company!
 Safety devices on page 11

Safety
Version 1.2.4 - 2022-10-26 15Translation of original instruction
S275N | S275NV EN
S275N_S275NV_GB_1.fm
The inspection prior to initial commissioning is not required if the operator receives confirmation
from the manufacturer or installer that the electrical systems and operating equipment comply
with the accident prevention regulations.
Permanently installed electrical systems and operating equipment are considered constantly
monitored if they are continually serviced by qualified electricians and inspected by means of
measurements in the scope of operation (e.g. monitoring the insulation resistance).

2.1 Emissions
The generation of noise emitted by the metal band saw is 73 dB(A) at idle.
If the metal band saw is installed in an area where various machines are in operation, the noise
exposure (immission) on the operator of the metal band saw at the working place may exceed
80 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level.
Though there is a dependency between the degree of the noise emission and the degree of the
noise disturbance it is not possible to use it reliably to determine if further precaution measures
are required or not.
The following factors influence the actual degree of the noise exposure of the operator:
Characteristics of the working area, e.g. size or damping behaviour,
other noise sources, e.g. the number of machines,
other processes taking place in proximity and the period of time, during which the operator
is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
This information about the noise emission should, however, allow the machine operator to
evaluate the hazards and risks more easily.
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protection.
We generally recommend the use of noise protection and hearing protection.

3 Delivery, interdepartmental transport, assembly and
commissioning
3.1 Notes on transport, installation, commissioning
Improper transport, installation and commissioning is liable to accidents and can cause damage
or malfunctions to the machine for which we do not assume any liability or guarantee.
Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen-
sioned industrial truck or a crane to the installation site.
WARNING!
Severe or fatal injuries may occur if parts of the machine tumble or fall down from the
forklift truck or from the transport vehicle. Follow the instructions and information on the
transport box.
Note the total weight of the machine. The weight of the machine is indicated in the "Tech-
nical data" of the machine. When the machine is unpacked, the weight of the machine
can also be read on the rating plate.
Only use transport devices and load suspension gear that can hold the total weight of
the machine.
WARNING!
The use of unstable lifting and load suspension equipment that might break under load
can cause severe injuries or even death. Check that the lifting and load suspension gear
has sufficient load-bearing capacity and that it is in perfect condition.
Observe the accident prevention regulations issued by your Employers Liability Insur-
ance Association or other competent supervisory authority, responsible for your com-
pany. Fasten the loads properly.
3.1.1 General risks during internal transport
WARNING: TILTING DANGER!
The machine may be lifted unsecured by a maximum of 2 cm.
Employees must be outside the danger zone, i.e. the reach of the load.
Warn employees and advise them of the hazard.
Machines may only be transported by authorized and qualified persons. Act responsibly during
transport and always consider the consequences. Refrain from daring and risky actions.
Gradients and descents (e.g. driveways, ramps and the like) are particularly dangerous. If such
passages are unavoidable, special caution is required.
Before starting the transport check the transport route for possible danger points, unevenness
and faults.
Danger points, unevenness and disturbance points must be inspected before transport. The
removal of danger spots, disturbances and unevenness at the time of transport by other
employees leads to considerable dangers.
Careful planning of interdepartmental transport is therefore essential.

3.2 Unpacking the machine
Transport the metal band saw in its packing crate to a place near its final installation location
with a forklift before unpacking it.
If the packaging shows signs of possible transport damage, take the necessary precautions not
to damage the machine when unpacking. If any damage is discovered, the carrier and/or
shipper must immediately be notified of this fact to establish any claim which might arise.
Inspect the machine completely and carefully, making sure that all materials, such as shipping
documents, manuals and accessories supplied with the machine have been received.
Compare the delivery volume with the delivery note.
3.3 Requirements regarding the installation site
Organize the working area around the metal band saw according to the local safety regulations.
INFORMATION
In order to attain good functionality and a high processing accuracy as well as a long service life
of the machine, the place of installation should fulfil certain criteria.
Please observe the following points:
The device must only be installed and operated in a dry and well-ventilated place.
Avoid places nearby machines generating chips or dust.
The installation site must be free from vibrations also at a distance of presses, planing
machines, etc.
The substructure must be suitable for the metal band saw. Also make sure that the floor has
sufficient load bearing capacity and is level.
The ground must be prepared in a way that potential coolants cannot penetrate the floor.
Any parts sticking out such as stops, handles, etc. have to be secured by measures taken
by the customer if necessary in order to avoid endangering persons.
Provide sufficient space for the personnel preparing and operating the machine and
transporting the material.
Also make sure the machine is accessible for setting and maintenance works.
Provide for sufficient backlight (Minimum value: 500 lux, measured at the tool tip). At lower
illumination intensities, additional illumination has to be ensured e.g. by means of a
separate workplace lamp.
INFORMATION
The mains plug of the metal band saw must be freely accessible.
