Safety Instructions

1)

Use caution during assembly and operation of the 3D printer to ensure 
no sharp edges will cut you. 
 

2)

Always operate the printer a safe distance away from inflammable items. 
Use in well-ventilated areas. 
 

3)

Heatbed, Hotend and cartridge heater become hot during operation. DO 
NOT touch hot surfaces, because they can cause severe burns. Allow the 
hotend to cool before touching it without proper tools. 
 

4)

DO NOT touch the chords of 3D printer if hands are wet.There are 
chances of getting shock. 
 

5)

Always use your 3D printer in a well-ventilated and clean area. Gas 
emitted by melting of Polylactide (PLA) or Acrylonitrile butadiene styrene 
(ABS) can contain contaminants that are harmful to breathe. Never 
breathe the air that comes directly out of the hotend. This air is not 
suitable for breathing. 
 

6)

Electrical pins and sensors are delicate. Handle with care. Unless 
instructed, DO NOT force components together. Read the instructions 
carefully to prevent damaging parts during assembly or operation.
