3.6 Exhaust System

Install the provided exhaust pipe directly onto the fan. The pipe can be expanded to a full length of about 5 feet (1.5 m).
The other end should be connected to a dedicated purifier or (if the fumes are not hazardous and meet local
and national air safety standards) placed out a window. NEVER operate the laser if the vent is not purifying or
removing the fumes produced by the target material. Research materials before use and never operate the laser on
any (such as PVC, teflon, and other halogen-containing substances) that can produce corrosive, hazardous, or even
deadly fumes.

3.7 Main Power Connection

Confirm that the labeling beside the connection socket on the machine matches your power supply. Connect one end
of the main cable to the connection socket and the other end to a grounded outlet. Under NO circumstances should
you switch on the device if the voltages do not correspond.
Fluctuation along the line should be less than 5%. If this is exceeded, the fuses will blow. They are located in the
connection socket and are accessible from the exterior. Similarly, do not connect this device to standard extension
cords or power strips. Connect it directly to a grounded outlet or use a surge protector rated over 2000J.
3.8 Control Computer
See the software manual for details on the requirements for the control computer. The control computer can be
connected using the provided USB cable (via the port marked "USB Cable to PC"), using the provided Ethernet
cable ("Ethernet Cable"), or using the internet if the engraver has been connected to it using the Ethernet cable. If
the control computer is directly connected to the engraver, it should not be placed more than 15 feet (4.5 m) away
in order to avoid possible interference to the signal on its line. Familiarize yourself with the software's image design
features and laser control settings before using it to operate the laser.
