3.3 Safety instructions
Please be very cautious during any interaction with the
printer
. This printer is an
electrical device with moving parts and hot-temperature areas.
1. The device is for indoor use only. Do not expose the printer to rain or snow. Always keep
the printer in a dry environment at a minimum distance of 30 cm from other objects.
2. Always place the printer on a stable place, where it cannot fall or tip over.
3. The printer supply is household power outlet 230 VAC, 50 Hz or 110 VAC / 60 Hz. Never
connect the printer to a different power supply; it may cause malfunction or damage to the
printer.
4. Place the power cord so you cannot stumble on it or step on it, or otherwise expose it to
any potential damage. Also make sure that the power cord is not mechanically or otherwise
damaged. If so stop using damaged power cord immediately, and replace it.
5. When you disconnect the power cord from the socket, pull the plug rather than the cord to
reduce the risk of damage to the plug or to the AC outlet.
6. Never disassemble the printer power supply; it does not contain any parts that could be
repaired by an unskilled worker. All repairs must be performed by a qualified technician.
7. Do not touch the nozzle or heatbed when the printer is printing or warming up. Note that
the temperature of the nozzle is 210-300 °C (410-572 °F); heatbed temperature can reach
over 100 °C (212 °F). Temperatures above 40 °C (104 °F) can cause harm to the human
body.
8. Do not reach inside the printer while it is still in operation. An injury may be caused by its
moving parts.
9. Prevent children from unsupervised access to the printer even when the printer is not
printing.
10. Do not leave the printer unattended while it's still on!
11. Plastic is being melted during printing which produces odors. Set up the printer in a
well-ventilated place.
