NOTES
1. Do not use the printer any way other than described herein in order to avoid personal
injury or property damage.
2. Do not place the printer near any heat source or flammable or explosive objects. We
suggest placing it in a well-ventilated, low-dust environment.
3. Do not expose the printer to violent vibration or any unstable environment, as this
may cause poor print quality.
4. Before using experimental or exotic filaments, we suggest using standard filaments
such as ABS or PLA to calibrate and test the machine.
5. Do not use any other power cable except the one supplied. Always use a grounded
three-prong power outlet.
6. Do not touch the nozzle or printing surface during operation as they may be hot.
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. Such cloths may
become tangled in the printers moving parts leading to burns, possible bodily injury,
or printer damage.
8. When cleaning debris from the printer hotend, always use the provided tools. Do not
touch the nozzle directly when heated. This can cause personal injury.
9. Clean the printer frequently. Always turn the power off when cleaning, and wipe with
a dry cloth to remove dust, adhered printing plastics or any other material off the
frame, guide rails, or wheels . 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.
