Trotec ProMarker OEM Operating Manual page 21

Class 1
The accessible laser radiation of Class 1 laser systems does not pose any hazard for the skin or eyes.
In order to operate the Promarker as a Class 1 laser system, the following points must be observed:
Notice
– The entire course of the laser beam should be shielded to prevent radiation.
– Any covers providing access to laser areas which may be removed without using a tool
should be fitted with suitable safety latches.
– Inspection windows in the housing should be fitted with safety glass suitable for the laser
output and the shaft length of the laser (DIN EN 207).
Class 2 (US: class II)
The accessible laser radiation of Class 2 (US: Class II) laser systems does not pose any hazard for the skin.
Diffuse reflections as well as any short-term irradiation of the eyes (exposure time max. 0.25 seconds) also
pose no risk due to the low output power.
However, it is possible to suppress the natural eyelid closure reflex and stare into the class-2 laser beam for
a time long enough for the eyes to get injured.
The ProMarker uses a Class 2 pilot laser. In order to prevent irritation of the eyes during operation, the
operator should not look directly at the laser source. Diffuse reflections of the pilot laser are entirely
harmless.
