Safety Guidelines
The following general guidelines, together with the instructions provided
throughout this user guide, ensure user safety while operating and maintaining
the system. If the system is not operated as specified, the user's safety
may be compromised.
Printer Installation
➢ Installation and removal of the printer should only be done by qualified service
personnel.
➢ Connect the printer (and the UPS unit) to the electric outlet using a power
cable that is safety-certified.
➢ The electric outlet should be easily accessible, near the printer.
➢ Never connect the power plug to an outlet that does not have a ground (earth)
wire, and never disconnect the ground. Doing so might expose the operator
to serious danger from electric shock.
➢ Do not connect the power cable supplied with the printer to any other
equipment.
➢ The following safety statement is followed by translations to Finish,
Norwegian, Swedish and Danish, as required by local regulations:
“The machine must be connected to a grounded power outlet.”
❒ FI: Laite on liitettävä suojakoskettimilla varustettuun pistorasiaan.
❒ NO: Apparatet må tilkoples jordet stikkontakt.
❒ SE: Apparaten skall anslutas till jordat uttag.
❒ DK: Apparatets stikprop skal tilsluttes en stikkontakt med jord, som giver
forbindelse til stikproppens jord.
➢ Leave a minimum of 60 centimeters (24 inches) between the printer and walls
or other objects.
➢ For Japan: The power cable supplied is provided for connecting the printer
to the AC electric source. Do not use it with other equipment.
Printer Operation
➢ This printer should not be installed in locations where children are likely to be
present.
Cette imprimante ne doit pas être installée dans des lieux pouvant accueillir
des enfants.
➢ The printer should only be operated by persons trained by an authorized
Stratasys representative.
➢ All persons operating or maintaining the printer should know the location of
first aid and emergency equipment and how to use it. Never block access
to this equipment.
➢ Keep fingers and other body parts clear of the printer when closing the door.
➢ Never attempt to open the printer while it is working.
➢ Never override the interlock safety switch.

Stratasys J5 Series User Guide 2 Safety
DOC-09270 Rev. B 2-5
➢ If the interlock safety switch ever fails, do not use the printer.
➢ Several parts of the printer remain extremely hot even after it has stopped
operating. Avoid touching the print block.
UV Radiation
The UV light used in the printer emits dangerous radiation.
➢ If the UV light remains on when the printer is open, do not stare directly at it.
Shut down the printer and call your Stratasys service provider.
Printer Maintenance
➢ Service operations should be performed only by qualified personnel who
have been instructed in relevant safety precautions.
➢ Notify co-workers and those who have access to the printer before beginning
non-routine and hazardous work.
Report any potential dangers and safety-related accidents to your safety
officer or to other appropriate authorities.
Model and Support Materials
Model and Support materials are made of chemical substances. Although
precautions must be taken when handling these materials directly, all Model and
Support materials used by the printer are handled in sealed cartridges. Normally,
operators of the printer should never be directly exposed to hazardous materials.
In the unlikely event of a leak or spill, follow the instructions that are included with
the material cartridges used.
➢ Store Model and Support materials indoors, in a dry area with adequate
ventilation, between 15-25 degrees Celsius (59-77 degrees Fahrenheit).
Never expose them to flames, heat, sparks, or direct sunlight.
➢ Keep Model and Support materials away from areas where food and drink
are stored, prepared and consumed.
➢ Uncured printing material is considered a hazardous substance, requiring
certain precautions when directly handling it. To prevent skin irritation, wear
neoprene or nitrile gloves. If there is any chance that Model and Support
materials might splash into the eyes, wear safety goggles. Prolonged direct
contact with printing materials can cause an allergic reaction.
➢ When handling UV-cured models that may not be completely cured on the
surface, common latex gloves are adequate.
➢ To prevent respiratory irritation, ventilate areas where Model and Support
materials are used. If the printer is not equipped with an exhaust duct, the
room ventilation system should replace the air 4–6 times per hour.
➢ Clean up Model-material and Support-material spills with disposable towels
or other absorbent, non-reusable material, such as sawdust or activated
charcoal. Rinse the spill area with denatured or isopropyl alcohol (IPA),
followed by soap and water. Dispose of the absorbent material in accordance
with local regulations.

Stratasys J5 Series User Guide 2 Safety
DOC-09270 Rev. B 2-6
➢ Do not wash contaminated clothing at home; clothing should be
professionally laundered.
➢ Dispose of contaminated shoes, belts and other leather items in accordance
with any applicable regulations. Absorbed printing material may re-expose
the user when these items are worn.

Stratasys J5 Series User Guide 2 Safety
DOC-09270 Rev. B 2-7
First Aid for Working with Printing Materials
In general, try to avoid direct contact with uncured printing material. If skin or
eyes come into contact with it, wash the area immediately and thoroughly with
water, and follow these first-aid instructions.
The Material Safety Data Sheet (MSDS) that accompanies printing materials
contains important safety information. Keep this in an accessible place where
these materials are used and stored.
Contact with Skin
If uncured printing material comes in contact with skin, wash the affected area
immediately and thoroughly with soap and cool water, then remove
contaminated clothing. Pay particular attention to flushing the hair, ears, nose
and other parts of the body that are not easily cleaned.
➢ Use cool water to prevent skin pores from opening, so that the liquid material
does not easily penetrate the skin.
➢ Do not use solvents to clean skin.
➢ If large areas of skin have been exposed, or if prolonged contact results in
blisters, seek medical attention. In any case, if irritation persists, seek medical
attention.
➢ Avoid the accidental transfer of printing material from the hands to other
areas of the body, especially to the eyes.
➢ If protective cream was used, do not reapply it until the skin has been
completely cleansed.
Contact with Eyes
If uncured printing material comes in contact with the eyes, flush immediately
with large amounts of water for 15 minutes and seek medical attention.
➢ Avoid sunlight, fluorescent light, and other sources of ultraviolet radiation.
Wearing contact lenses when handling liquid printing materials is not
recommended. If the liquid splashes into the eyes when contact lenses are worn,
immediately remove the lenses and flush the eyes with water.
➢ Clean and disinfect the contaminated lenses.
➢ Do not wear contact lenses until eye irritation disappears.
Ingestion
If printing material is swallowed, refer to the instructions included with the
cartridge. Seek medical attention immediately.

Stratasys J5 Series User Guide 2 Safety
DOC-09270 Rev. B 2-8
Inhalation
Vapors from printing materials can be irritating to the respiratory system. If
respiratory irritation occurs, expose the victim to fresh air immediately.
➢ If the victim has stopped breathing, perform artificial respiration or
cardiopulmonary resuscitation.
➢ Seek medical attention immediately.
➢ Keep the victim warm but not hot.
➢ Never feed anything to an unconscious person.
➢ Oxygen should be administered by authorized personnel only.
Waste Disposal
Fully cured printed models can be disposed of as ordinary office trash. However,
special care is required when handling printer waste (uncured printing material).
➢ When removing the waste container from the printer, wear neoprene or nitrile
gloves.
➢ To prevent liquid waste from splashing into the eyes, wear safety goggles.
➢ Liquid waste from the printer is classified as hazardous industrial waste.
Therefore, printing-material waste must be packaged and disposed of in a
manner that prevents human contact with it and contamination of water
sources.
➢ Empty Model-material and Support-material cartridges contain residue of
their contents. Some leakage of this residue may occur through the broken
cartridge seal. Therefore, handle and store empty cartridges with care.
➢ Do not attempt to reuse empty cartridges, and do not puncture them.
➢ Dispose of used cartridges and waste containers in accordance with local
regulations.
➢ Discard contaminated clothing, shoes, empty containers, etc., in accordance
with any applicable regulations.
