AIntroduction
Technifor is a used, pending and/or registered trademark belonging to
Gravotech Group or one of its subsidiaries.
Thank you for choosing TD412 Technifor.
For more information on products, visit www.technifor.com website.
To ensure security and productivity, read this manual before starting-up the
equipment.
For help, contact Gravotech (see contact list, last page).
1. General Instructions
Laser safety
• Class 4 laser device designed for integration - See declaration of compliance.
• Observe norm EN 60825-1 concerning the controls and signage (access panels, doors, emergency stops...).
• Operators and service personnel must receive laser safety training. Carefully read the "Laser Safety" chapter.
For help, contact Gravotech (see contact list, last page).
• It is mandatory that the operator wear eye protection with the suitable filter lenses (DIR L6, 1064 nm - standard
EN207: 2010).
Marking head
• The optical fiber is not disconnectable on the marking head side, only on the CCU side.
• Electronic dimensional drawings available upon request
• The optical fiber, linking the CCU to the marking head, must respect a minimum bending radius of 90 mm
(3.543 in).
• Minimize shocks and vibrations on the marking head.
• The optical fiber must be connected before the Laser is started up (CCU side).
• Never ship the CCU connected to the marking head.
• Allow approximately ± 15 mm (0.591 in) for the focal point adjustment (list of accessories available upon
request: contact us).
• If the equipment is stored at a temperature inferior to 10 0C (50 0F) or superior to 35 0C (95 0F), leave it 24h at
a temperature between 15 0C (59 0F) and 35 0C (95 0F) before start-up.
Control Unit
• After unpacking the CCU, connect the optical fiber to the laser diode without delay (CCU side).
• In difficult environments (i.e.: oily mist, small dust particles, high humidity, high temperature...), place the CCU in
a filtered or even air-conditioned cabinet to protect it from damage.
• Allow clearance (connections and cables): analyse the CCU’s integration in order to avoid problems due to the
fiber’s minimum bend radius.
• Use a cooling system in a high temperature environment.
• In the event of power problems, install a UPS (power conditioner).

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 toskin 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.

General Instructions
Wearing safety glasses
Safety goggles and appropriate clothing providing efficient protection against laser radiation and its effects are
mandatory whenever in an area where laser radiation emission exceeds or equals class 3B AEL (accessible
emission limit).
As a user, it is mandatory to declare the use of class 4 laser station to current authorities and to follow their safety
recommendations.
• Avoid any exposure to laser radiation.
• Do not put hands or an object in the laser beam’s trajectory.
• Never stare into the primary laser beam.
• Avoid direct eye exposure to diode laser beam.
• Do not direct the beam towards other persons, openings or windows.
• Do not remove protection hoods or short-circuit the securities.
• Electrical interventions on the system can only be carried out by competent LT/HT
personnel.
• In the event of an incident or even doubts concerning the functioning of the instal-
lation, inform the person in charge of laser safety.

3. Potential hazards related to materials worked with
Fumes and toxic particles
The processing of parts using this type of Laser causes thermal and photo-electric (molecular) deterioration of the
material. Even micro-quantities of the by-product (soot or fumes), created during Laser marking, may accumulate
over a long period. Some of these by-products may prove to be hazardous to humans.
Health side-effects to the operators may include poisoning, allergies or cancer.
Here are some examples of the most sensitive materials:
• plastics and rubber
• painted materials
• anodized and galvanized metals
• ceramics
• materials containing lead or mercury
For a more detailed list of the risks related to the material worked with, consult Annex A of the ISO 11553-1:2005
norm.
In this case, adapt an extraction system (with filtration if necessary) to the marking station. This system vacuums
eventual emissions from the marking area.
It must be linked to:
• either a centralised vacuum system with an external evacuation.
• either an independent system dedicated to the marking station, which removes fumes and particles using
activated carbon filters.
The user must observe national legislation in force concerning chemical agent exposure limits.
For more information, contact us.
Examples of secondary radiation risks
The use of a class 4 laser device can generate:
• a risk of fire or explosion due to materials or inflammable substances
• UV radiation
•Xrays
• high intensity visible light when marking on certain materials
Laser marking certain materials emits dangerous fumes and particles that may be
toxic and/or damage the equipment.
In this case, adapt an extraction system (with filtration if necessary) to the marking
station.
