Congratulations on the purchase of your KERN LASER SYSTEM!
Everyone at Kern takes great pride in manufacturing a quality laser system and providing the best technical
support for years after the sale. Feel free to give us a call when in need of assistance with your Kern Laser
System.
Please take time to review the instructional videos posted on the kernlasers.com website. This will aid in
connecting all the components of the system and get everything aligned and calibrated before operation can
begin. All connections are labeled at the factory to help simplify the process. Everyone operating the laser
system must read and understand the Kern laser manual before using the system.
Installation of a phone next to the laser system is encouraged and will help in expediting troubleshooting and
answering any technical questions that may arise about our software or operation of the system.
All components need to be inspected during setup and installation of the system to make sure damage did not
occur in the shipping process. Please call Kern immediately at 218-631-2755 with any questions or concerns.
Safety
Please read through these basic safety guidelines before operating the laser system:
•Wear certified laser safety eyewear (wavelength 10.6 µm @ optical density 6) when operating or
viewing the laser system.
•Direct eye contact with the invisible output beam will cause serious injury and may cause blindness.
•Never leave the laser system unattended while cutting or engraving.
•Always wear rubber gloves or finger gloves when handling the optic lens. Lenses are made of zinc
solenoid and can be harmful to your health.
•Cutting acrylic or thicker material at slow speeds and/or low air pressure may cause fires.
•The 1” honeycomb grid and 1” ecolite grid must be cleaned on a regular basis and replaced if needed.
If material residue buildup accumulates in the grid work, materials may catch on fire during the
cutting and/or engraving process. Clean with detergent and water.
•Clean and remove any material buildup from the bottom of the table’s vacuum chamber. If the black
painted surface is worn, remove the grid work and recoat the worn spots inside of the table’s vacuum
chamber with hi-temp flat black spray paint. Wait for the paint to dry and fumes to subside before
operating the system.
•Laser cutting and engraving are extremely high temperature burning processes. Many materials may
emit harmful gasses when cut or engraved with a laser. Refer to the materials MSDS safety sheet to
verify if the material is safe to laser cut or engrave before proceeding.
•Use proper ventilation within the room housing the laser system. The exhaust air from the vacuum
blower may need to be filtered for certain types of materials.
•Do NOT oil or lubricate the Teflon coated lead screws. The black Teflon coating will flake off and jam
up the nut. A clean, dry, soft cloth can be used to wipe down the lead screw.
•The “DANGER” laser safety sign included with each system is required to be posted at each entrance
of the room that the laser is located in. If additional safety signs are needed, please call Kern.
•At least one person must be assigned as the Laser Safety Officer (LSO). Their duty is to fully
understand and train all other personnel on safe operating procedures and aspects of the laser
system. Call Kern with additional information regarding LSO training.
•It is imperative to understand the hazards of operating a motion control system equipped with a laser
without proper training.
•Do not stare at the laser beam when cutting or engraving. Small amounts of ultra-violet light can be
emitted from the vaporized material.
•Operators are not to be under the influence of drugs or alcohol.
•Wear close fitting clothing. Operators are not to be wearing loose clothing. Operators must remove all
jewelry (rings, bracelets, necklaces, or similar items) as they can be hazardous and can be electrical
conductive for burns.
•People with long hair are to tuck hair back possibly into a cap.
•If safety questions arise, please call Kern at 218-631-2755 for assistance.

Sealed Beam Path
Operators and maintenance personnel are protected from hazards on the machine by a sealed tube that
encloses the optical assembly of the laser.
This interlock is considered a necessary part of this machine. This interlock that controls access to the optical
assembly of the laser source is needed to protect maintenance personnel. This makes it possible to access the
laser source when maintenance personnel need to align the laser. The laser is only permitted to operate under
normal safety conditions. The hinged movable cover needs to be interlocked to ensure operators are not at
risk of exposure to reflected laser light or toxic fumes.
Operating Modes
Kern’s DHS model is normally operated in Automatic mode. In Manual mode it is possible to fire the laser
source, operate X and Y motion systems and check air pressure. Manual mode can only be used if all safety
interlocks are in operation. Manual Mode is normally used to test or calibrate the laser system.
Access to Manual mode is password protected
There is a need to operate the laser source while aligning the laser beam when the lid over the optical assembly
is open. This is made possible by introducing a Maintenance MANUAL mode of operation that can only be
accessed by entering a password. In Maintenance mode it is possible to operate the laser with the hinged lid
over the optical assembly open, but only under necessary enhanced safety conditions.
Laser Processed Materials and Applicable Standards
Laser material processing can generate by-products as air contaminants that can be noxious, toxic and even
fatal. The resulting vapors, fumes, and/or particles should be thoroughly evaluated and the adequacy of your
provisions for fume extraction, filtering and venting should be carefully considered.
Refer to Section 7.3 of the ANSI Z136.1-2007 “American National Standard for Safe Use of Lasers”, to the
exposure criteria in 29 CFR 1910 Subpart Z from the United States Government, and to the Threshold Limit
Values (TLV’S) published by the American Conference of Governmental Industrial Hygienists (ACGIH).
It may also be necessary to consult with state or local government agencies regarding restrictions on the
outdoor venting of vapors.
Before cutting or engraving any material, acquire the MSDS Safety Data Sheet for the material to verify the
product is safe to cut or engrave. Fumes from the cut material may be toxic.
CDRH Standards
This laser system complies with the requirements of the current version of the following:
U.S. Department of Health and Human Services, Title 21 Code of Federal Regulations, Subchapter J, Part
1040.10, Performance Standard for Laser Products.
The above regulation is sometimes referred to as the CDRH regulation, the FDA regulation or 21CFR 1040.
It is recommended to strictly follow the user requirements in the ANSI Z136.1-2007 “American National
Standard for Safe Use of Lasers”. These standards deal with such subjects as the appointment of a laser
safety officer, the operation of the system in a limited access area by trained authorized personnel and the
posting of signs warning of the potential hazard. The ANSI Standard manual is available from the Laser
Institute of America. Call 1-407-380-1553 or visit www.laserinstitute.org to obtain a copy.

Refer to the Kern website link http://www.kernlasers.com/pw/login.htm for system setup videos.
Safety eyewear must be worn during the setup process. Two sets of laser safety glasses are included
with the laser system. The recommended setup and operational testing is as follows:
Description
The DHS machine consists of a rectangular frame that is constructed from heavy angle section steel.
The frame has four uprights on each corner, which act as legs. These support a worktop tray that is
made of steel plate. The tray has a flat base and is welded on top of the legs. There are ribs that run
the full length of the worktop tray and stiffen the tray. These are structural members and are deep
enough to create a plenum for the extraction of dust or toxic fumes generated during engraving or
cutting operations. Aluminium ecolite and honeycomb grid layers form the worktop. Two flexible
ventilation hoses are connected to the end of the worktop tray and these are used to place the tray
under vacuum. A blower is provided to create a vacuum and collect dust and toxic fumes. Worktop
grids are designed to suit the various materials that can be cut or engraved by the laser system.
Materials to be cut or engraved must be flat to within 1 mm to 2 mm. This flatness will ensure that
the material will be held under vacuum. Crossbeams run between the legs at a lower level. These
are positioned above floor level and are covered by flat plates on three sides. The flat plates receive
the control system enclosure and a DC power supply and guide a cable chain conduit.
A gantry runs above the grids and spans the full width of the tray. The gantry is able to travel the
full length of the worktop tray. The gantry has two vertical columns at each end. These are
connected to a flat plate that runs in a clear space underneath the worktop tray. A linear bearing
block is mounted on top of this plate at each end. The bearing block is specially shaped and each
block runs along guide rails that are secured to the underside of the worktop tray. The gantry is
connected to a lead screw and a drive belt connects the lead screw to a servo motor. The servo
motor is mounted to the underside of the worktop enabling the gantry to be traversed in the X axis.
The lead screw has a spring loaded anti-backlash nut that is mounted on the underside of the gantry
and is manually lubricated with lithium grease. The lead screw runs in bearings blocks, one at each
end of the worktop, and these must also be lubricated manually using lithium grease.
The front of the gantry carries an optical head that travels the full width of the worktop tray. The
optical head consists of a laser tube containing a lens, a means of injecting an assist gas that is used
to keep the lens clean and an optical nozzle. The optical head is optically connected to a laser
source. The optical head is mounted on a carrier that runs the full width of the gantry. Linear bearing
blocks are mounted on each side of the carrier. The bearing blocks are specially shaped and run in
guides on each side of the carrier. The guides are bolted to the gantry frame. A timing belt that is
operated by a servo motor moves the carrier. The timing belt runs around sprockets and is
connected to the carrier on one side. The shaft of each sprocket runs in a bearing block, one at each
end of the gantry. This enables the carrier to be traversed in the Y-axis.
The optical head moves in a vertical plane and is guided by four guide rods that are supported by the
carrier. The optical head is connected to a lead screw and a timing belt connects the lead screw to a
servo motor. The servo motor is mounted on the carrier enabling the optical head to be traversed in
the Z-axis. The lead screw has a spring loaded ant backlash nut that is mounted on the side of the
optical head and is manually lubricated with lithium grease. The lead screw runs in bearings at the
top and bottom of the carrier and these must also be lubricated manually using lithium grease. Two
limit switches are used to determine when the optical head has been driven to its maximum upper
and lower limits of travel.
The top of the gantry carries a CO2laser source. The laser source is excited by a DC RF power
source. On water cooled models, the RF source must be water cooled. A chiller provides cooling
water and must be set to operate at a temperature of 20 to 21°C (68 – 70 °F). The HSE machine
must not be operated in a room at a temperature in excess of 27 °C (80 °F).
The laser is first directed at a collimator. In the case of 150 watt lasers the beam is passed through a
beam shaper. On leaving the collimator the beam is directed at a mirror that turns the beam through
8

90°. The beam is then directed at an alignment disk followed by a further mirror that turns the beam
through another 90°. These can be adjusted in two stages to focus the laser beam. The beam is
then directed through a further alignment disk followed by a further mirror that turns the beam
through another 90°and adds cross hairs. On leaving the optical head the beam is thereafter
directed at the work piece. There is a shutter on the output of the beam shaper that can be closed
mechanically to block the path of the laser beam and electrically shut off the KLMC box.
The DHS laser system operates from instructions that are loaded onto a computer. Various operating
menus are accessible through the computer and are presented in different windows. The control
system manages the position of the laser head, laser intensity, rates of acceleration and
deceleration, cutting speed and many other fine adjustments.
Cutting or engraving instructions on the computer are converted with the KCAM software into
information that is recognized by the machine. KCAM software is used to control all movements of
the machine and the intensity of the laser.
Any safety limitations such as maximum laser intensity, cutting speeds or limits of travel are
controlled by software and independently backed up by electromechanical control systems or
firmware to establish Category-3 architecture as detailed in EN13849-1.
The acceptable engraving speed range is from 0.01 inches per second to 25 inches per second for
non-metallic materials and 0.01 inches per second to 20 inches per second for metals. The
acceptable cutting speed range is from 0.01 inches per second to 10 inches per second for non-
metallic materials and 0.01 inches per second to 5 inches per second for metals. In one mode of
operation the modulation frequency sets the intensity of the laser. This ranges from 50 – 10000 Hz.
In another mode of operation a pulse rate sets the intensity of the laser. This ranges from 0 to 600
pulses per inch.
The 150W machine must be configured with metal cutting hardware to successfully cut metal. High
pressure oxygen must be passed through the optics to initiate a cut and achieve a clean edge. The
KCAM software and a pressure regulator valve control the use of oxygen. A 150 watt laser can cut up
to .090” mild steel and up to .075” stainless steel.
A blower pulls through two 4” ports at the back of the table. This blower removes fumes and small
debris that drops into the table chamber. A second blower is connected at the nozzle assembly.
Intended Purpose
The DHS machine is capable of operating at speeds of up to 25 inches per second using a laser beam
that operates at a consistent power level to provide high quality laser cutting or engraving over the
entire area of the laser worktop. A gantry, which spans the full width of the worktop, carries one
optical head. The machine can achieve resolutions from 50 dpi to 1200 dpi. Normally the machine is
offered with resolutions from 300 dpi and 600 dpi.
Cutting and engraving speeds are determined by the laser size, material being processed, and the
desired edge quality. The machine operates at its highest speed when cutting in straight lines, and
slows down when cutting patterns as they become more intricate. Typical cutting speeds range from
150 mm (6 inches) per minute up to 15 m (600 inches) per minute. Cutting speeds and laser power
are adjusted by selecting line colors that are generated by KCAM software.
The Kern DHS model is designed to cut wood, metal, and plastic. Other materials can be cut, but a
MSDS sheet must first be reviewed first. As a result of laser cutting and engraving operations, many
of these materials produce toxic fumes when they are heated therefore blowers are provided to
remove such material. Material that is collected must be removed by a dust extraction system
provided by the user. The required extraction rate is 42,475 Liters/minute (1500 cfm). See Material
Capability and Fume Extraction page. If there are any doubts, users should perform a hazard and
risk assessment on given material or contact Kern for advice.
9

The machine is capable of receiving flat material up to a thickness of 75mm (3 inches). Operating
instructions identify full details of the dimensions of the materials that can be handled.
This Kern DHS model is designed for use indoors in a normal working environment. The intended
operating temperature range is 16 - 32 degrees Celsius and a relative humidity range from 50 -
75%.
Lighting
Ambient lighting must be sufficient for operators to view all parts inside of the machine. Ambient
lighting is sufficient if maintenance personnel can see all internal parts when fixed or hinged sheet
metal access panels have been removed and there is no need to provide additional internal lighting.
Internal lighting should achieve a light intensity of 100 to 200 Lux (Lumens/m2).
It is recommended that local ambient lighting should achieve a light intensity of 300 Lux
(Lumens/m2) around the HSE machine and in the immediate vicinity of those parts of the machine
where maintenance must be performed.
Uncrating
Carefully inspect the crate before it is unloaded from the delivery truck. Note any damage to the
crate with the shipping company driver and call Kern immediately.
Open the crate using a drill with a Phillips head bit. Once inside the crate inspect the laser system
and all boxes inside for any visible damage. All boxes may then be removed from the crate.
Material Handling, Floor Space and Leveling
The center of gravity is located at the center point of the crate. A forklift with extensions may be
needed to move the wooden crate the machine is shipped in. The chart below shows the dimensions
and weight of the laser machine.
Approximately 2 – 6 feet of clearance around the machine is needed to safely operate and perform
maintenance on the laser system. Additional space will make loading/unloading of materials even
easier.
10

Leveling the table may be necessary using shims or leveling pads underneath the legs. Make certain
the bottoms of all legs are tight to the floor. Do not bolt the stand to the floor as this may twist the
table.
Computer
Remove the computer and monitor from their boxes. Place the computer beneath the laser system.
Mount the monitor on the computer arm using the four small bolts provided.
Verify that the computer and monitor are able to be connected to a 230V supply. Plug in the power
cables to both the computer and monitor. The electrical panel has outlets for the computer and
monitor for a 230V connection. Power information can typically be found on the back of the
computer and monitor.
The monitor has a USB cable that allows the two USB ports on the side of the monitor to be used.
These are useful for using thumb drives for loading files into the computer. The mouse and
keyboard cables can connect to the USB ports on the back of the computer tower.
Connect the USB DSP box to the back of the computer tower. Plug in the monitor cable to the
computer tower. Wires that run through the monitor arm can be accessed by removing the screws
from the plastic plates on the underside of the arm.
The computer is networkable so files may be accessed from other computers on the network. This
allows for file sharing between a design computer and the laser computer.
Control Boxes
Place the KLMC on top of the DSP unit and set them on the shelf on the front of the system. All
wiring harness connectors for the DSP and KLMC are labeled for ease of installation. The Kern KLMC
and DSP boxes may be installed according to the directions below.
