3.LASER SAFETY INSTRUCTIONS.
When used as directed, the machine includes a Class 1 laser system
that is safe for both users and bystanders. However, invisible lasers, laser
tubes, and their electrical connections are still very dangerous. They can
cause serious property damage and personal injury if not used or modified
with care, including but not limited to the following:
Lasers can easily burn nearby combustible materials.
Some working materials may produce radiation or harmful gases during
Processing.
Direct contact with the laser can cause bodily harm, including severe
burns and-irreparable eye damage.
Do not modify or disable the security features provided by this device. Do
not modify or disassemble the laser, and do not use the laser if it has
been modified or disassembled by anyone other than a trained and
skilled professional. Dangerous radiation exposure and other injuries
can result from the use of adapted, modified, or otherwise incompati-ble
equipment.
Never keep any part of the cabinet open during operation unless
(required) through doors. Never interfere with the laser beam, do not
place any part of the body on any part of the laser path during the
operation, and never attempt to observe the laser directly. When using a
pass-through door or otherwise risking exposure to a laser beam, take
steps to protect yourself from potentially reflected laser beams, including
the use of personal protective equipment, such as specially designed
protective eyewear, to filter engravers with an optical density (OD) of 5+
for specific wavelengths of lasers.
During operation, do not stare or allow others to stare at the laser beam
continuously, even if the lid is closed and/or protective glasses are worn.
Use this engraving machine only when its auto-shut-off function is
working properly. When you first get this engraver, if you subsequently
notice any issues, test it before doing any other work (see below). If
