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.
