1.13 Rescuing persons in dangerous situations after the CNC retrofitting
If the machine was subject to a subsequent retrofitting with CNC controlled drives, the following
additional dangerous situations such as squeezing and sticking of parts of the body may result
hereof.
If the machine had been switched off in a dangerous situation using the Emergency-Stop function, it is no longer possible to actuate the axis by means of the electromotor in order to rescue
the squeezed person.
In this case it is necessary to release the machine manually.
This releasing of the X-axis and of the Y-axis is performed using an appropriate tool (e.g. a flat
wrench), which is inserted on the hexagon nut at the shaft end which is opposite to the drive.
It is only possible to release the Z-axis using a separate handwheel which is inserted on the free
shaft end of the manual crank drive.
WARNING!
It is imperatively necessary that the tools are available to release the machine in case of a
dangerous situation.
Therefore, keep the wrench and the handwheel always in close proximity of the CNC con-
trolled machine.

2.11 Emissions
The emission of the drilling-milling machine is below 76 dB(A). If the drilling-milling machine is
installed in an area where various machines are in operation, the acoustic influence (immission)
on the operator of the drilling-milling machine may exceed 85 dB(A).
INFORMATION
This numeric value had been measured on a new machine under conventional operating conditions. Depending on the age or wear of the machine, the noise behavior of the machine might
change.
Furthermore, the extent of the noise emission is also depending on manufacturing
influence factors, such as speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is an emission level and not necessarily a safe
working level.
Unless the degree of noise emission and the degree of noise disturbance are depending on one
another it is not possible to use it in order to reliably determine if it is necessary to take further
preventive measures or not.
The following factors influence the actual degree of the noise disturbance of the
operator:
• Characteristics of the working chamber, e.g. size or damping behavior,
• Other noise sources, e.g. the number of machines,
• Other processes proceeding nearby and the period during which the operator is exposed to
the noise.
Furthermore, the admissible pollution level may be different from one country to another due to
the national regulations.
This information regarding the noise emission should allow the operator of the machine to perform a better evaluation of the endangerments and risks.
CAUTION!
The machine operator has to wear an appropriate ear protection depe nding on the overall
stress caused by noise and on the basic limit values.
We generally recommend using a sound and ear protection.
