1 Safety Information
Thank you for choosing Raycus fiber laser. This User Guide provides important safety,
operation, warranty and other information. Please read it carefully before you use this product. In
order to ensure safe operation and optimal performance of the product, please follow the
warnings, cautions, operating procedures and other instructions accordingly.
1.1 Symbols Used in this User Guide
WARNING: Refers to a potential hazard that may leads to a personal
injury or death.
CAUTION: Refers to potential a hazard that may leads to general
personal injury or product damage.
1.2 Laser Classification
This series of lasers are classified as a high power Class 4 laser instrument according to the
European Community standards EN 60825-1, clause 9. This product emits invisible laser
radiation at or around a wavelength of 1080 nm, and the total power radiated from the laser is
greater than 8000W (depending on model). Direct or indirect exposure of this level of light
intensity may cause damage to the eyes or skin. Despite the radiation being invisible, the beam
may cause irreversible damage to the retina and/or cornea. Appropriate and approved laser safety
eyewear must be worn all the time while the laser is operating.
WARNING: You must use appropriate laser safety eyewear when this
device is operating. The laser safety eyewear is selected according to the
range of wavelengths emitted from this product. The end user must
ensure that the laser safety eyewear being used protects against light
emitted by the device over its entire range of wavelengths. Please verify
that the personal protective equipment (e.g. enclosures, viewing
windows or viewports, eyewear, etc.) being utilized is adequate for the
output power and wavelength ranges listed on the product.

1.3 Safety Labels
The position of the safety labels on products varies depending on the model of the
continuous-wave fiber laser, as shown in Figure 1:
Figure 1 Safety Label Locations of RFL-C8000S
These safety labels include warning labels, apertures through which laser radiation is
emitted and labels of certification and identification, etc. Specifications of these labels are as
follows:

1.4 Optical Safety
Any dust on the end of the collimator assembly can burn the lens and damage the laser.
CAUTION: If the output of the device is delivered through a lens with
an anti-reflection coating, make sure that the lens is of good quality and
clean.
1.5 Electrical Safety
(1) Make sure your product is grounded through the PE line of the AC power cord. The
grounding must be firm and reliable.
WARNING:Any interruption from the protective earth will electrify
the enclosure, which may result in personal injury.
(2) Make sure that the correct voltage of the AC power source is used.
CAUTION: Failure to connect the correct voltage could damage the
product.
1.6 Other Safety Rules
(1) Never look directly into the laser output port when power is supplied to the laser.
(2) Avoid using the laser in a dim or darkened environment.
(3) If this device is used in a manner not specified in this document, the protection provided
by the device may be impaired and the warranty will be voided.
(4) There are no operator serviceable parts inside, and all maintenance must be performed
in Raycus or by qualified Raycus personnel. Do not try to remove covers, or electrical shock
may be caused, and warranty will be void.

Remove all the contents from the packing case. Take extra care when removing the unit out
of the packing case to ensure that the fiber optic cable is not twisted, hauled or damaged. A
comprehensive packing list is included with the system documentation. Check all items against
the list and contact Raycus immediately if there is any missing item or evident damage to the
unit. DO NOT attempt to install or operate the laser, if there is any evident or suspected damage
to the unit.
It is recommended to keep the packing materials, as they will be necessary if you ever need
to ship the unit back for service at a later date.
CAUTION: The fiber optic cable and output head is precise optic
instrument, any vibration or impact to the output head, and twist or
excessive bend to the cable will damage the instrument.

Warning：
1) Ensure reliable grounded before using the laser.
2) The laser output is connected to the output cable. Please check the laser output carefully
to prevent dust or other contamination. Use special paper when cleaning the laser output
lens.
3) If the laser is used in accordance without the method specified in this manual, the laser
may be in abnormal working state and cause damage.
4) It is strictly forbidden to install the laser output when the laser is in operation.

Laser operating temperature range
Green area: The dew point temperature is 22℃that is lower than the laser
cooling water temperature, which can be used safely；
Red area: If the dew point temperature is higher than22℃ and exceeds the
laser cooling water temperature by 22℃, there must bedew condensation,
and measures must be taken.
Measure 1: Dehumidifier works for 10-15 minutes in standby mode(laser
power and cooling water should be on state );
Measure 2: Installing cabinet air conditioner to reduce ambient
temperature.
2.5 Precautions for Use
1) Before supplying the power to the device, make sure that the correct voltage of the AC
power source is used. Failure to connect power source correctly will damage the device;

2) Failure to follow the instructions may cause malfunction and damage to the device, such
damage is not covered by warranty.
3) It is very important to ensure the cleanness of the calibrated laser output head, otherwise
it will cause irreparable damage to the laser.
4) Please inspect the output head carefully for dust or other contaminations. Use
appropriate lens paper to clean it if necessary. Do not touch the output lens at any time; as well
as remember to cap the output head when it is not in use, and make sure the cap is clean;
5) Failure to follow the specified instructions may result in the loss of laser power, and
such loss will not be covered by the warranty.
