A. Foreword
1. Appreciation
ThankyouforchoosingLW2Touch-Gravotech.
Gravotech is pleased to count you among the users of its engraving and traceability solutions.
For help, contact Gravotech.
For more information on products, visit www.gravotech.com website.
2. Information
To ensure security and productivity, read this manual before starting-up the
equipment. It provides details about the installation and use of the equipment.
Keep this manual in case you need to refer to it.
Fortheattentionofusershavinganindividualcardiacassistdevice󰄈tted:
Our equipment is designed and manufactured with the greatest care in order to
guarantee their compliance with the EMC Directive currently in force. This means
that the levels of electromagnetic emissions produced by this equipment when in
operationarelimitedanddonotexceedthethresholdsde󰄈nedbytheDirective.
However, multiple factors make it impossible to guarantee the total absence of risk
forusershavingacardiacassistdevice󰄈tted.Consequently,itisrecommendedthat
standing for a prolonged period within less than 1 m (3.281 ft) of an operating machine
should be avoided.

Introduction
4. Workstationsafety
• Turno󰘯themachinebeforebeginninganycleaning,maintenanceorrepairprocedure.
• Never unplug a cable while the Control Unit is turned on.
• 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.
• In the event of power problems, install a UPS (power conditioner).
• ThemarkingheadandtheControlUnitmustbecleanandprotectedfromdust.Exterioropticsmustbe
veri󰘰edandcleanedifnecessary.
Warning: Hazardous moving parts
ControlUnit/markinghead
Formoreinformation,consultthemanualofthemachineinquestion(Fiber-Hybrid-Green-CO2Energy
Series).
Door motorization
Manipulate the door with caution before switching on:
1. Removethecover(See:Step1:Openingthecasing).
2. Remove2screwsinordertoreleasethecounterweights(See:Step 2).
Handling the machine
• In the event of an extended period of non-use, unplug the power cable and protect the machine.
• Neverpourorspillliquidonthemachine(drinks,cleaningproducts,etc.)exceptwhererecommendedby
Gravotech.
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.

G.Laser safety
1. Recommendations and safety regarding laser devices
Personnel safety
THIS MACHINE HAS A CLASS 4 LASER BOXED IN A CLASS 1 CASING. THIS MACHINE IS CONSIDERED
AS CLASS 2M DUE TO ITS VISIBLE LASER DIODE (RED).
• The machine is considered as Class 1 when the door is closed. In this case, the security enclosure of
theLW2TouchislockedandsealedagainstpotentialLaserradiationemissionsundernormalworking
and safety conditions. The modi󰘰cation of locking systems, or the removal of these systems or labels
designedforsafety,willresultinexposuretohazardsfromtheLaserbeam.Anymodi󰘰cationisprohibited.
The LW2 Touch isclosed,lockedandlabelledtoensurethatitworksincompletesafety.Thelabelsand
security devices must not be removed or concealed by the operator.
• ThemachineisconsideredasClass2Mwhenthedoorisopened(emissionpowerequaltoorlessthan
1mW).Inthiscase,thesecurityshutterintheLasermoduleclosestoavoidanyriskofLaseremission.
Themarkingcanonlybecarriedoutifthedoorisclosed.
Ifthemachineisbeingintegrated,theinstallerisresponsibleforensuringthe󰄈nalequipmentconforms
to current legislation. Observe EN 60825-1 standard concerning the controls and signage (access
panels,doors,emergencystops...).Example:applicationofsafetypictograms,installationofsuitable
guards, use of the electrical safety channel provided on the equipment (non-exhaustive list).
Only trained personnel aware of the risks posed by the machine are authorized to use it. 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.
Laser radiation is invisible, but exposure, direct or scattered, is hazardous to skin and eyes.
Donotusethismarkingequipmentinanexplosiveenvironment.Noin󰄉ammablematerialshouldbe
locatedwithinthemachineenclosurenearthere󰄉ectedbeam(operator'sshirt,curtains,wallcovering
innon-syntheticmaterial:󰄈rehazard).Forsafetyreasons,neveroperatethemachinewithoutconstant
surveillance.
This equipment is not suitable for use in locations to which children have access.
Thislasercanproducedangerousdi󰓐usere󰄉ections.Itmayleadtoskinandeyeinjuriesaswellas
a󰄈rerisk.Itsuserequiresextremecaution.Firepreventionandprotectionequipmentistheuser's
responsibility. Do not look at the Laser beam continuously when marking, even through the protective
glass. The light intensity may strain the eye.

Laser safety
General Instructions
• 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
installation, inform the person in charge of laser safety.
Wearing safety glasses
Under normal conditions of use, the machine operates at Class 1 - 2M: protective goggles are not necessary.
Laser radiation safety glasses are mandatory whenever in an area where laser radiation emission exceeds
class 3B AEL.
As a user, it is mandatory to declare the use of class 4 laser station to current authorities and to follow their
safety recommendations.

4. Potentialhazardsrelatedtomaterialsworkedwith
Fumes and toxic particles
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 󰄈ltrationif necessary) to themarking
station.
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-e󰘯ects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
standard.
In this case, adapt an extraction system (with 󰘰ltration if necessary) to the marking station. This system
vacuumschips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󰘰lters.
The user must observe national legislation in force concerning chemical agent exposure limits.

The use of a class 4 laser device can generate:
• Ariskof󰘰reorexplosionduetomaterialsorin󰘱ammablesubstances
• UV radiation
• X rays
• Highintensityvisiblelightwhenmarkingoncertainmaterials
Re󰘱ectedbeam
Specialintegrationisrequiredwhenmarkingsomematerialstopreventthebeamre󰘱ecting.
