2.2 Emissions
The generation of noise emitted by the metal belt saw is 73 dB(A) at idle.
If the metal belt saw is installed in an area where various machines are in operation, the noise
exposure (immission) on the operator of the metal belt 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, mate-
rial 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 eval-
uate 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.

3.1 Unpacking the machine
Transport the metal belt 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 ship-
per 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.
3.2 Transport
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 metal belt saw. Use only transport and
load suspension devices that can hold the total weight of the metal belt saw.
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 capacity and that it is in perfect condition. Fasten the loads properly.
Never walk under suspended loads!

3.4 Requirements regarding the installation site
Organize the working area around the metal belt 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 belt 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 trans-
porting 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 sepa-
rate workplace lamp.
INFORMATION
The mains plug of the metal belt saw must be freely accessible.
