LENSES
CAUTION: Lenses must not be touched.
Fused silica lenses are used in the F-Series laser system. If the lens has been soiled, it must
be thoroughly cleaned before any operation.
Scan Head Mirrors
WARNING: Never touch the mirrors of the scan head.
The mirrors are inside the scan head and there is a small risk of touching them when
cleaning the lens.
If the mirrors have been touched accidentally, wash hands thoroughly with water and soap.
Fumes and dust from Beryllium metal can be hazardous if inhaled.
Noise
All systems emit during operation a noise level lower than 80dB(A). No personal protective
equipment against noise is needed.
Crushing
There is a crushing hazard during installation and operation due to:
• Product moving along the laser head.
• Products moving into and out of protective housing.
• Doors and maintenance openings of protective housings.
Laser Marking Process
Potential fire risks could result from examples as listed below. This list is not considered to
be complete. Local conditions must be considered as well.
• Printing on not specified material (e.g. easily inflammable or explosive
materials).
• Invalid parameter settings (e.g. very low mark speed).
• Invalid parameter settings due to corrupted print data.
• Printing constantly on the same product (e.g. no product movement caused by
various reasons).
• Inflammable gases or materials inside the working area.
• In printing mode the laser beam is controlled by software which must be
considered as part of the risk assessment.
• Install a fire detector near the laser to monitor the marking process.
