capacity and are in perfect condition. Observe the accident prevention regulations
issued by your Employer s Liability Insurance Associ ation or other competent
supervisory authority, responsible for your company. Fasten the loads properly.
Never walk under suspended loads!
1.12.3 Mechanical maintenance work
Remove or install protection safety devices before starting any maintenance work and
re-install them once the work has been completed. This includes:
Covers,
Safety indications and warning signs,
Earth (ground) connections.
If you remove protective or safety devices, re-fit them immediately after the completing the
work.
Check if they are working properly!
1.13 Accident report
Inform your superiors 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 faster the causes can be eliminated.
INFORMATION
We point out the specific dangers when performing works with and on the milling machine
when describing such works.
1.14 Electrical system
Have the electrical milling machine/equipment checked regularly, at least every six months.
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. Immediately disconnect the milling machine if there are any
anomalies in the power supply!

2.10 Emissions
The generation of noise (emission) emitted by the milling machine is less than 74 dB(A).
If the Milling machine is installed in an area where various machines are in operation, the
noise exposure (immission) on the operator of the milling machine 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 chamber, 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
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 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.
