Notes
1. Do not use the Printer in any other way not described herein in order to avoid personal injury or
property damage.
2. Do not place the Printer near flammables, explosives or heat sources. It is best to place it in a well-
ventilated, low-dust environment.
3. Do not expose the Printer to violent vibration or any unstable environment, because this will cause poor
print quality.
4. The filaments recommended by the manufacturer are preferred as to avoid clogging in the extrusion
head or Printer damage.
5. Do not use any other power cable except the one supplied. Use a grounded three-prong power outlet.
6. Do not touch the nozzle or hot bed during printing. Keep hands away from machine while in use to
avoid burns or personal injury.
7. Do not wear gloves or loose clothing when operating the Printer. Preventing the movable parts from
being involved in the squeeze or cutting injury to hunman boday or printer damage.
8. Clean off filament from the nozzle tip with the provided pliers before the nozzle cools. Do not touch the
nozzle directly. This can cause personal injury.
9. Clean the Printer frequently. Usually clean it while power-off, clean the body of the machine with a dry
cloth to remove dust, adhered printing materials and other material of the guide rails. Use glass cleaner
or isopropyl Alcohol to clean the print surface before every print for consistent results.
10. Children under 10 years of age should not use the Printer without supervision.
