Do not work on the CNC machine, if your concentration is reduced, for example, because

you are taking medication.
Stay on the CNC machine until the program is termi-

nated.
The running program can be identified by means of
the signal lamp.
- Green light: Program run active
- Yellow light: Malfunction
- Red light: Actuated emergency stop push button
Safely and firmly clamp the workpiece before switching on the CNC machine.

Never change the dosing of the coolant supply during operation.

Never open the sliding door of the separating protective unit when the CNC-program is run-

ning.
WARNING!
When chipping magnesia materials (aluminium-/magnesium alloys), spontaneously
inflammable or explosive particles (powder, dust, chips) might be generated, which
might cause a fire and/or explosion (deflagration).
Magnesium is designated a dangerous material in the list of dangerous materials and
preparations according to para. 4a of the Ordinance of Hazardous Substances.
In case of a fire with magnesium, only use appropriate and admitted extinguishing
agents. Never extinguish using water. If burning magnesium is extinguished with water,
this might lead to dangerous reactions (hydrogen gas). Water would be decomposed in
its components hydrogen (H) and oxygen (O).
Only the following extinguishing agents are permissible:
solid extinguishing agent of fire class D (fires involving metals)

dry covering salts for magnesium

a mixture of sand and cast chips

argon (Ar) or nitrogen (N

If fine mist and smoke is generated at the workplace, suction units must be provided in
order to avoid the accumulation of ignitable mixtures and emissions.
We provide information about the specific dangers when working with and on the CNC machine
in the descriptions for these types of work.

Safety during maintenance

Inform the operators in good time of any maintenance and repair works.
Report all safety-relevant changes and performance characteristics of the CNC machine. Any
changes must be documented, the operating instructions updated and machine operators
instructed accordingly.
