1.11 Safety during operation
WARNING!
Danger to life from electromagnetic fields. Electromagnetic fields (EMF) are generated by
the operation of electrical power equipment such as transformers, converters or motors.
People with pacemakers or implants are at a special risk in the immediate vicinity of
these devices/systems.
Ensure that the persons involved are the necessary distance away (minimum 2 m).
CAUTION!
Danger due to inhaling dust and mist that are hazardous to health.
Depending on the materials to be machined and the agents used, dusts and mists can
arise that are detrimental to health.
Ensure that the harmful dust and mist generated are safely sucked off at the point of
origin and routed away from the working area or filtered. To do so, use a suitable
extraction unit.
CAUTION!
Risk of fire and explosion by using flammable materials or cooling lubricants.
Extra precautionary measures must be taken before machining flammable materials (e.g.
aluminium, magnesium) or using combustible agents (e.g. spirit) to avert a health
hazard.
WARNING!
Before switching on the metal belt saw make sure that there are
no dangers generated for persons,
no objects are damaged.
Avoid any unsafe work methods:
Make sure that nobody is endangered by your work.
The rules specified in these operating instructions must be observed during assembly,
operation, maintenance and repair.
Do not work on the metal belt saw, if your concentration is reduced, for example, because

A second person must be present during work on live components to disconnect the power in
the event of an emergency. Disconnect the metal belt saw immediately if there is a malfunction
in the power supply !
Comply with the required inspection intervals in accordance with the factory safety directive,
operating equipment inspection DGUV, formerly BVG.
The operator of the machine must ensure that the electrical systems and operating equipment
are inspected with regards to their proper condition, namely,
by a qualified electrician or under the supervision and direction of a qualified electrician,
prior to initial commissioning and after modifications or repairs, prior to recommissioning
and at certain intervals.
The deadlines must be set so that arising, foreseeable defects can be detected in a timely man-
ner.
The relevant electro-technical rules must be followed during the inspection.
The inspection prior to initial commissioning is not required if the operator receives confirma-
tion from the manufacturer or installer that the electrical systems and operating equipment com-
ply with the accident prevention regulations, see conformity declaration.
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).
1.15 Inspection deadlines
Define and document the inspection deadlines for the machine in accordance with § 3 of the
Factory Safety Act and perform an operational risk analysis in accordance with § 6 of the Work
Safety Act. Also use the inspection intervals in the maintenance section as reference values.
1.16 Hydraulic system
The system is under a pressure of up to 280 bar.
WARNING!
Serious injuries from hydraulic liquid escaping under high pressure!
Possible loss of the eyesight!
Make sure the hydraulic system is depressurized before opening any component or line. Wear
safety goggles and protective clothing when carrying out any work on the hydraulic system.
Even after switching off the central power supply at the machine, the hydraulic system can still
be under stored pressure.
If hydraulic liquid squirts into your eyes, immediately rinse it with plenty of water. Immediately
seek medical assistance.

2.7 Emissions
The noise emission of the metal band saw is 76 to 80 dB(A). If several machines are operated
at the location of the metal band saw, the noise exposure (immission) to the operator of the
metal band saw at the workplace may exceed 80 dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. Depending on the age or wear of the machine, or the duty cycle of the
hydraulic unit, the noise behaviour of the machine may change. Furthermore, the noise emis-
sion also depends on production engineering factors, e.g. speed, material and clamping condi-
tions.
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 operator of the machine
to more easily evaluate the hazards and risks.
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protectors.
We generally recommend the use of noise and ear protectors.
