The printer should be placed out of the reach of children or pets.
Only operate your 3D printer in room temperatures of 5-30℃ with an ambient humidity between 20%-70%
2. Electrical Safety
● Always use a properly grounded outlet and the cable provided to prevent damage to your printer.
● Please unplug the 3D Printer if it will not be in use for a while.
● Do not use outdoors, indoor use only.
● Always keep the printer in a dry environment and out of direct sunlight.
● Do not use the 3D Printer during thunderstorms.
3. Personal Safety
● Do keep your hair, clothing and gloves away from moving parts.
● Do not operate the 3D Printer while you are tired or under the influence of drugs, alcohol or medication.
● Parts of the 3D printer will get very hot during use, Do not touch the nozzle, hot end assembly or the build plate when the printer

4. CAUTION!
● Do not leave the 3D Printer unattended.
● Do not make any modifications to the printer other than any approved SainSmart upgrades.
● When removing a model be careful not to use excessive force.
● The 3D printer must only be operated in a well ventilated area, noxious gasses can be released.
● Do not exceed the maximum print temperature of your printer or the filament you are using.
● When loading or unloading filament make sure the printer nozzle is well clear of the build plate (>50mm).
