2.8 Emissions
The generation of noise emitted by the metal band saw is 73 dB(A). 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 proper operating conditions.
Depending on the age respectively on the wear of the machine it is possible that the noise
behaviour of the machine changes. Furthermore, the factor of the noise emission is also
depending on manufacturing influencing factors, e.g. speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is the emission level and 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 the proximity and the period of time during which the oper-
ator 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 shall allow the
operator of the machine to more easily evaluate the endangering and risks.
CAUTION!
Depending on the overall noise exposure and the basic limit values the machine
operators must wear an appropriate hearing protection.
We generally recommend to use a noise protection and a 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.
