1.1 Symbols Used in this User Guide
WARNING: Refers to a potential personal hazard.
CAUTION: Refers to a potential product hazard.
1.2 Laser Classification
This model 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 9xx nm, and the total light power radiated from the optical
output is greater than 2000-3000 W. Direct or indirect exposure to this level of light intensity
may cause damage to the eye or skin. Despite the radiation being invisible, the beam may cause
irreversible damage to the retina and/or cornea. Appropriate and approved laser safety goggles
must be worn all the time while the laser is operational.

(6) Do not look into the output head directly. Wear appropriate safety goggles all the time when
operating the laser.
2.5 Announcements
Please make sure that the correct voltage of AC power source is used. Failure to connect
power source correctly will damage the device. Use of controls or adjustments other than those
specified herein may result in hazardous radiation and damage to the laser. It is critical to keep
the lens clean. Please cap the output terminal when it is not in use. Do not touch the output lens.
If necessary, you can use appropriate lens paper and alcohol to clean the lens. Failure to follow
the specified instructions may result in the loss of laser power. Such loss is not covered under
warranty.

turned on. Usually there are shorted contacts in the processing head, please check the head to
ensure that.
3.2 Installation Procedures
(1) Check if the power supply has the correct voltage (380VAC±10%，50/60Hz), and the earth
line is connected reliably.
(2) Place the laser firmly on the desirable position.
(3) Fix the casters at the bottom side of the laser.
(4) Check the output head and clean it if necessary. This procedure must be performed by
Raycus personnel or person authorized by Raycus.

Water temperature setting:
Summer (ambient temperature higher than 30℃): 29±0.5℃;
Winter (ambient temperature lower than 30℃): 25±0.5℃.
Purified water should be used. In order to prevent mildew growing, we recommend to add
alcohol about 10% of total volume. The cooling system should equip with filter. Check and clean
the filter every six months.
If the product is used in an environment that ambient temperature is between -10 ℃and
0℃, we recommend to use 30% alcohol, and replace it every two months.
If the product is used in an environment that ambient temperature is below -10℃, you must
use chiller with both heating and cooling functions, and keep it in full-time operation.
When connecting to the laser for the first time, ensure that the flow and return connections
are correct.
If you will not use the laser for a long time, water should be emptied from the laser, and
then block inlet and outlet. Failure to do so may lead to permanent equipment damage.
CAUTION: Please set the water temperature in strict accordance with the
requirements above. Too low temperature may lead to condensation in the
Laser module and the output head. This can cause serious damage to the
equipment.

CAUTION: The cooling system should be turned on 1 min earlier before
the laser is turned on. Check any water leakage and make sure that the
water temperature reach the set point before you start the laser.
