Laser Safety Instructions - Omtech POLAR+ User Manual

• DO NOT operate this engraver with its cooling liquid hotter than 104 ℉ (40 ℃ ). If this temperature
is ever approached, stop using the laser but allow the exhaust and water-cooling systems to
continue running to clear and cool the machine.
• DO NOT leave this engraver unattended during operation. Observe the engraver
throughout the operation and, if anything seems to be operating strangely,
immediately cut off ALL power to the machine and contact either our customer
service or your dedicated repair service. Similarly, ensure the engraver is FULLY turned
off (including using the emergency stop switch) after each use.
• DO NOT allow minors, untrained personnel, or personnel suffering from physical or mental
impairment that would affect their ability to follow this manual and the software manual to
install, operate, maintain, or repair this engraver.
• Any untrained personnel who might be near the engraver while it is in operation MUST be
informed that it is dangerous and fully instructed on how to avoid injury during its use.
• ALWAYS keep a fire extinguisher or other flame-retardant system nearby in case of
accidents. Ensure that the local fire department's phone number is displayed nearby.
In the case of a fire, cut electrical power before dousing the flame. Familiarize yourself
with the correct range for your extinguisher before use. Take care not to use the
extinguisher too close to the flame, as its high pressure can produce blowback.

or non-intended use. Used or modified without care, they can cause serious property damage and
personal injury including but not limited to the following:
• The laser will easily burn nearby combustible materials
• Some working materials may produce radiation or harmful gasses during processing
• Direct exposure to the laser will cause bodily harm including serious burns and
irreparable eye damage
As such,
• DO NOT modify or disable this engraver's provided safety features. Do not modify or
