Do not use the printer any way other than described here in order to avoid personal injury or property damage.
Do not expose the printer to violent vibration or any unstable environment, as this may cause poor print quality.
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.
Do not use any other power cable except the one supplied. Always use a grounded three-prong power outlet.
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.
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.
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.
Children under 10 years old should not use the printer without supervision.
This machine is equipped with a security protection mechanism. Do not manually move the nozzle or printing platform mechanism manually while booting
up, otherwise the device will automatically power off for safety.
Users should comply with the laws and regulations of the corresponding countries and regions where the equipment is located (used), abide by professional ethics, pay attention to
safety obligations, and strictly prohibit the use of our products or equipment for any illegal purposes. Creality will not be responsible for any violators' legal liability under any circustance.
Before using experimental or exotic filaments, we suggest using standard filaments such as ABS or PLA to calibrate and test the machine.
Do not touch the nozzle, hotbed or motor while the printer is in operation, otherwise you may get burned.

4.8 Install X-axis passive block
A. Snap the brass sleeve on the left side of the X-axis timing belt into the extruder back support plate.
B. Fix the X-axis passive block to the X-axis profile. (Be careful not to screw it down and make sure the X-axis passive block can slide along the X-axis profile.)
C. After winding the X-axis timing belt around the X-axis passive block, snap the brass sleeve at its right end into the extruder back support plate.
D. Push the X-axis passive block to the right to tension the X-axis timing belt to the same state as the Y-axis timing belt, then tighten the set screw on the
X-axis passive block.
