1. Recommendations and safety regarding laser devices
Personnel safety
Recommendations
• The marking head and the Control Unit must be clean and protected from dust. Exterior optics must be verified
and cleaned if necessary.
• Position the Control Unit horizontally, in a dry, ventilated area, at least 20 cm (7.874 in) from the floor (Recom-
mendations for integration)
• Use the appropriate protection when equipment is used in a polluted environment. Use of these protections are
the user’s or the integrator’s responsibility.
• Never unplug a cable while the Control Unit is turned on.
• Grounding must be done according to the regulations in effect to ensure the safety of the personnel. The con-
nection to the single phase power supply is made with a standard, 3 pin plug with grounding. It must be equip-
ped with an adequately calibrated 30 mA differential cut-off and protection device.
• Do not use this marking equipment in an explosive environment.
Gravotech will not be held responsible for injuries resulting from disregard for the above operating instructions or
other general safety rules applicable to the use of this equipment or resulting from misuse. Furthermore, disregard
for the instructions will void the warranty.
This machine is equipped with a class 4 laser source. This laser can produce
dangerous diffuse reflections. It may lead to skin and eye injuries as well as a fire risk.
Its use requires extreme caution.
Laser radiation is invisible, but exposure, direct or scattered, is hazardous to skin and
eyes.
It is mandatory that the operator wear eye protection with the suitable filter lenses.
The area in which the machine is used must be limited to authorized and protected
personnel only.
The operator is not to wear reflective objects on his/her arms/hands (i.e.: jewellery).
Marking reflective materials (those with a copper, gold or silver base) or materials with
a polished surface represents a hazard both for the operator and the machine.
No inflammable material is to be close to the reflected beam (i.e.: operator’s shirt,
curtains, wall covering in non-synthetic material: fire hazard).
Only Gravotech personnel, or persons authorized by Gravotech may service the
elements that constitute the marking machine. Any intervention by unauthorized third
party would exclude Gravotech’s liability.
