injury
This Class 4 laser product emits invisible infrared laser radiation in
the 10.6 µm CO2wavelength band.
Do not allow laser radiation to enter the eye by viewing direct or re-
ected laser energy. CO2laser radiation can be reected from metallic
objects even though the surface is darkened. Direct or diuse laser
radiation can inict severe corneal injuries leading to permanent eye
damage or blindness. All personnel must wear eye protection suitable
for 10.6 µm CO2radiation when in the same area as an exposed laser
beam. Eyewear protects against scattered energy but is not intended
to protect against direct viewing of the beam—never look directly
into the laser output aperture or view scattered laser reections from
metallic surfaces.
Enclose the beam path whenever possible. Exposure to direct or dif-
fuse CO2laser radiation can seriously burn human or animal tissue,
which may cause permanent damage.
This product is not intended for use in explosive, or potentially
explosive, atmospheres.

Warning
serious
personal
injury
U.S. customers should refer to and follow the laser safety precautions
described in the American National Standards Institute (ANSI)
Z136.1-2007 document, Safe Use of Lasers. Procedures listed in this
Standard include the appointment of a Laser Safety Ocer (LSO),
operation of the product in an area of limited access by trained per-
sonnel, servicing of equipment only by trained and authorized person-
nel, and posting of signs warning of the potential hazards.
European customers should appoint a Laser Safety Ocer (LSO) who
should refer to and follow the laser safety precautions described in
EN 60825-1, 2007—Safety of Laser Products.
Warning
serious
personal
injury
Materials processing with a laser can generate air contaminants such
as vapors, fumes, and/or particles that may be noxious, toxic, or
even fatal. Material Safety Data Sheets (MSDS) for materials being
processed should be thoroughly evaluated and the adequacy of provi-
sions for fume extraction, ltering, and venting should be carefully
considered. Review the following references for further information
on exposure criteria:
ANSI Z136.1-2007, Safe Use of Lasers, section 7.3.
U.S. Government’s Code of Federal Regulations: 29 CFR 1910,
Subpart Z.
Threshold Limit Values (TLV’s) published by the American Confer-
ence of Governmental Industrial Hygienists (ACGIH).
It may be necessary to consult with local governmental agencies
regarding restrictions on the venting of processing vapors.
Warning
serious
personal
injury
The use of controls or adjustments or performance of procedures
other than those specied herein may result in hazardous radiation
exposure.
Hazard information
Warning
serious
personal
injury
The use of aerosol dusters containing dioroethane causes“bloom-
ing”, a condition that signicantly expands and scatters the laser
beam. This beam expansion can eect mode quality and/or cause
laser energy to extend beyond the connes of optical elements in
the system, possibly damaging acrylic safety shielding. Do not use air
dusters containing dioroethane in any area adjacent to CO2laser
systems because dioroethane persists for long time periods over wide
areas.

Synrad Firestar f-Series operator’s manual
Hazard information
Firestar®f-Series lasers should be installed and operated in manufacturing or laboratory facilities by trained
personnel only. Due to the considerable risks and hazards associated with the installation and operational
use of any equipment incorporating a laser, the operator must follow product warning labels and instruc-
tions to the user regarding laser safety. To prevent exposure to direct or scattered laser radiation, follow all
safety precautions specied throughout this manual and exercise safe operating practices per ANSI Z136.1-
2007 at all times when actively lasing.
Always wear safety glasses or protective goggles with side shields to reduce the risk of damage to the eyes
when operating the laser.
A CO2laser is an intense heat source and will ignite most materials under the proper conditions. Never
operate the laser in the presence of ammable or explosive materials, gases, liquids, or vapors.
The use of controls or adjustments or performance of procedures other than those specied herein may re-
sult in exposure to hazardous invisible laser radiation, damage to, or malfunction of the laser. Severe burns
will result from exposure to the laser beam.
Safe operation of the laser requires the use of an external beam block to safely block the beam from travel-
ing beyond the desired work area. Do not place your body or any combustible object in the path of the
laser beam. Use a water-cooled beam dump or power meter, or similar non-scattering, noncombustible
material as the beam block. Never use organic material or metals as the beam blocker; organic materials, in
general, are apt to combust or melt and metals act as specular reectors which may create a serious hazard
outside the immediate work area.
Other hazards
The following hazards are typical for this product family when incorporated for intended use: (A) risk of
injury when lifting or moving the unit; (B) risk of exposure to hazardous laser energy through unauthorized
removal of access panels, doors, or protective barriers; (C) risk of exposure to hazardous laser energy and
injury due to failure of personnel to use proper eye protection and/or failure to adhere to applicable laser
safety procedures; (D) risk of exposure to hazardous or lethal voltages through unauthorized removal of
covers, doors, or access panels; (E) generation of hazardous air contaminants that may be noxious, toxic, or
even fatal.
Disposal
This product contains components that are considered hazardous industrial waste. If a situation occurs
where the laser is rendered non-functional and cannot be repaired, it may be returned to SYNRAD, Inc.
who, for a fee, will ensure adequate disassembly, recycling and/or disposal of the product.
Additional laser safety information
The SYNRAD web site (http://www.synrad.com/LaserFacts/lasersafety.html) contains an online laser
safety handbook that provides information on (1) Laser Safety Standards for OEM’s/System Integrators,
(2) Laser Safety Standards for End Users, (3) References and Sources, and (4) Assistance with Require-
ments.
In addition, the Occupational Safety and Health Administration (OSHA) provides an online Technical
Manual (located at http://www.osha.gov/dts/osta/otm/otm_iii/otm_iii_6.html). Section III, Chapter 6 and
Appendix III are good resources for laser safety information.
Another excellent laser safety resource is the Laser Institute of America (LIA). Their comprehensive web
site is located at http://www.laserinstitute.org.

Agency compliance
The Agency compliance section includes subsections:
■Center for Devices and Radiological Health (CDRH) requirements
■Federal Communications Commission (FCC) requirements
■European Union (EU) requirements
SYNRAD lasers are designed, tested, and certied to comply with certain United States (U.S.) and
European Union (EU) regulations. These regulations impose product performance requirements related
to electromagnetic compatibility (EMC) and product safety characteristics for industrial, scientic, and
medical (ISM) equipment. The specic provisions to which systems containing Firestar f-Series lasers must
comply are identied and described in the following paragraphs. Note that compliance to CDRH, FCC,
and EU requirements depends in part on the laser version selected—Keyswitch or OEM.
In the U.S., laser safety requirements are governed by the Center for Devices and Radiological Health
(CDRH) under the auspices of the U.S. Food and Drug Administration (FDA) while radiated emission
standards fall under the jurisdiction of the U.S. Federal Communications Commission (FCC). Outside the
U.S., laser safety and emissions are governed by European Union (EU) Directives and Standards.
In the matter of CE-compliant laser products, SYNRAD, Inc. assumes no responsibility for the compliance
of the system into which the product is integrated, other than to supply and/or recommend laser compo-
nents that are CE marked for compliance with applicable European Union Directives.
Because OEM laser products are intended for incorporation as components in a laser processing system,
they do not meet all of the Standards for complete laser processing systems as specied by 21 CFR, Part
1040 or EN 60825-1. SYNRAD, Inc. assumes no responsibility for the compliance of the system into
which OEM laser products are integrated.
Center for Devices and Radiological
Health (CDRH) requirements
Important Note: Firestar f100 and f200 lasers are available in either Keyswitch or OEM versions;
Firestar f201 and f400 lasers are available only as OEM models.
Keyswitch models
Firestar f-Series Keyswitch model lasers comply with requirements for Class 4 laser products imposed
by the Radiation Control for Health and Safety Act of 1968. Under this Act, the U.S. Food and Drug
Administration (FDA) issued a performance standard in the Code of Federal Regulations (CFR) for laser
products. This performance standard, (21 CFR, Subchapter J, Part 1040.10) was developed to protect pub-
lic health and safety by imposing requirements upon manufacturers of laser products to provide an indica-
tion of the presence of laser radiation, to provide the user with certain means to control radiation, and to
assure that all personnel are adequately warned of potential hazards through the use of product labels and
instructions.
Product features incorporated into the design of Firestar f100 and f200 lasers to comply with CDRH
requirements are integrated as panel controls or indicators, internal circuit elements, or input/output signal
interfaces. Specically, these features include a Keyswitch (Keyswitch versions), lase and laser ready indica-
tors, remote interlock for power on/o, a laser aperture shutter switch, and a ve-second delay between
power on and lasing. Incorporation of certain features is dependent on the laser version (Keyswitch or
OEM). Table 1, Class 4 safety features, indicates which features are available on f-Series lasers, the type and
description of the feature, and if the feature is required by CDRH regulations.
