against unauthorised switching-on or switching-on by accident.
All machine parts as well as all dangerous voltages are switched off. Excepted are only the
positions which are marked with the adjoining pictogram.
1.15 Using lifting equipment
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
they have sufficient load carrying,
and that it is in perfect condition.
Observe the accident prevention regulations issued by your Employers Liability
Insurance Association or other supervisory authorities applicable to your company.
Fasten the loads carefully. Never walk under suspended loads!
1.15.1 Mechanical maintenance
Reinstall all protection and safety devices after any maintenance work once the work has been
completed.This includes:
covers,
safety instructions and warning signs,
grounding cables.
Check if they are working properly!
1.16 Accident report
Inform your supervisors and Optimum Maschinen Germany GmbH immediately in the event of
accidents, possible sources of danger and any actions which almost led to an accident (near
misses).
There are many possible causes for "near misses".
The sooner they are notified, the quicker the causes can be eliminated.
1.17 Electronics
Have the machine and/or the electric equipment checked regularly. Immediately eliminate all
defects such as loose connections, defective wires, etc.
A second person must be present during work on live components to disconnect the power in
the event of an emergency. Disconnect the machine 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.
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 set intervals.
The intervals must be set so that foreseeable defects can be detected in a timely manner, when
they occur.
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).
1.18 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.

2.1 Emissions
CAUTION!
The user must wear noise protection and hearing protection.
The A-weighted sound pressure level LpA is 84 to 87 dB.
The A-weighted sound power level LWA is 99 to 103 dB.
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 also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
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.
