Working with the laser or setting the system to service mode without
supervision is not permitted.
4.
Many materials, especially non-anodized aluminium, copper, silver and
gold, cannot be engraved with the laser engraver due to the very low
absorption of laser radiation. This means that most of the energy of the
laser beam is reflected. Therefore those materials must not be present in
the laser beam path as otherwise a reflected laser beam could destroy the
cover of the laser unit.
5.
Beam adjustment may only be done by trained personnel. Otherwise there
could be uncontrolled emission of laser radiation. There are only limited
possibilities to adjust the mirrors due to a mechanic restriction. These
restrictions may only be altered by authorized personnel.
6.
Before starting to work check whether the engraving of the material can
cause harmful fumes and whether the filters of your exhaust system are
suitable for these fumes. It is emphasized that it is the user’s responsibility
to obey the national and regional threshold values for dusts, fumes and
gases. (The maximum concentration of harmful substances must not be
exceeded). Never use the laser engraver without an exhaust unit with
appropriate filters for the treated material, as cutting or engraving certain
materials can produce vapours. Materials causing toxic or carcinogenic
smokes or fumes must not be treated without an exhaust unit with
appropriate filters. Furthermore it is the user’s responsibility to ensure the
safe removal and disposal of the smokes and particles from the laser
machine according to the national and regional threshold v alues.
In the US reference should be made to Section 7.3 in the ANSI Z136.1 -
1993 Standard for the safe use of lasers, to the exposure criteria in CFR
1910 Subpart Z from the US government, and to the Threshold Limit
Values (TLVs) published by the American Conference of Governmental
Industrial Hygienists (ACGIH).
7.
Please refer to the manual of your exhaust system regarding the change
intervals of the filters. We recommend to make a note of the last change of
filters on an adhesive label.
8.
PVC (Polyvinylchloride) must not be processed with the laser engraver.
If you have any questions please contact your supplier or Trotec.
