10 Do not use the printer any way other than described here in order to avoid personal injury or property damage.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 expose the printer to violent vibration or any unstable environment, as this may cause poor print quality.Before using experimental or exotic filaments, we suggest using standard filaments such as ABS or PLA to calibrate and test the machine.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.Children under 10 years old should not use the printer without supervision. 11
12 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.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. 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.Do not touch the nozzle, hotbed or motor while the printer is in operation, otherwise you may get burned.

Before switching on the machine, please check the tightness of the pulley by gently toggling it with your hand and check if it is idling
or stuck (as shown in Figure A).
If yes, please use an open-end spanner to adjust the hexagonal eccentric isolation column to make it rotate smoothly.

7.Auto LevelingThe above interface is for reference only.
7.1 Click on "Prepare → Auto Leveling" in the main interface, and then click on "Start" after the machine has returned home,
and wait for the machine to detect the platform to finish the auto leveling.

13
7.Auto LevelingThe nozzle is too far away from the platform, so the filaments can not
adhere to the platform.
Filaments are extruded evenly, just sticking on the platform.
The nozzle is too close to the platform, leading to insuficient filament
extrusion, even scraping the platform.
7.2 Click on "Move " in the settings screen, observe the height value of the Z-axis, set the value to 0 and then click on "Move "
to return.
Click on "Z-offset" and observe the gap between the nozzle and the platform by adjusting the Z-axis compensation value
so that the distance between the nozzle and the platform are about the thickness of a piece of an A4 paper.
0.08-0.1MM
7.3 Observe the print result after starting printing, and adjust the Z-axis compensation again if any exceptions occur.
The above interface is for reference only.

8.1.Preheating Method
A. Preheating mode 1: Click "Prepare" and select "Manual " to input corresponding values in the column of nozzle
temperature and hot bed temperature respectively.
B. Preheating mode 2: Click "Prepare" to select "Manual", select "PLA Preheat" or "ABS Preheat" according
to the type of consumables, and click "More Preheat" for other types of consumables.
14
8.Filament InfillNote: The printing preheating parameter standard has been adjusted at the factory. PLA preheating standard: nozzle temperature 200 °,
hot bed temperature 60 °; ABS preheating standard: nozzle temperature 250 °, hot bed temperature 100 °. If adjustment is required due
to printing materials or other reasons, you can select "Preheat PLA" or "Preheat ABS" in "Tune - ADV.SET" to adjust the corresponding
temperature. Click "More preheat set" for the preheating temperature adjustment of other consumables.

8.2 Filament Infill
8.Filament InfillA.When you wait for the temperature to rise, hang the filament over the material rack.
15
B.Pass through the Filament Sensor, then press the extruder handle and insert the filament along the extruder hole to the nozzle position.
If the filament flows out of the nozzle when the temperature reaches the target value, the filament is properly loaded.
Replacement of filaments:
1.When the machine has just started printing, cut filaments near the extruder and slowly feed filaments until they are fed into the material barrel.
2.When printing has finished and the machine has cooled down, heat the nozzle to 185℃+, then draw the filaments out and replace them by
referring to step 1.
3.To change the filaments during printing, adjust the printing speed to 10% and refer to step 2 for replacement.
For smooth insertion of the
filaments, the end position
of the filaments should be
handled as shown in the figure.
