Personal Safety and Avoiding Machine Damage
1. Safety precautions
Only use the consumable recommended by the original manufacturer and do not use other manufacturer’s consumable willingly,
as this could clog the nozzle. Do not attempt to use the machine in any way not described in the instructions for use to avoid
causing personal injury and property damage.
2. Properly choose the location
The machine is suitable for placement in ventilated, cool, dry and dustless environments.
Pay attention to the heat dissipation of the surrounding environment of the printer and avoid placing it on a thick carpet or
against a wall. Do not place this machine near ammable materials or high heat sources. Do not place the machine in high
vibration or other unstable environments. Do not stack heavy objects on this machine.
3. Use the power supply according to the specication
Use the power cord supplied with this machine. Do not plug or unplug the power plug while your hands are wet. Use a qualied
three-hole socket with a ground wire.
Be sure to fully insert the power seat when using the plug.
Do not intentionally pull or twist the distribution line of this machine to prevent open circuit or short circuit.
4. Pay attention during the printing process
Be careful not to set the hot bed temperature too high to avoid burns when using the hot bed function.
Do not use this machine under the age of 10 without supervision by personnel to avoid personal injury.
Do not touching the nozzle head to anti-scald during printing and just after printing.
If abnormal noise occurs during printing, immediately turn off the power switch and stop the printer, then contact your purchaser.
Always do product maintenance and regularly dust and lubricate the machine.
Do not attempt to disassemble or modify the machine not described in this manual to prevent the printer from damage or other
more serious safety incidents.
Periodically clean the printer with a dry cloth to remove dust and sticky print material. If you must use a damp cloth to clean.
Do not use ammable solvents and prevent ammable solvents from contacting the printer’s internal circuitry to cause re or
electric shock.
Notice after printing
Power off in a timely manner after printing. Use the remaining temperature of the nozzle promptly to clean the consumable on
the nozzle with the tool. Do not directly touch the nozzle. Try not to scratch the hot bed board when using a blade to take the
model. Ensure the machine is well maintained. Dust removal and lubrication should be performed in a timely manner the later
period. The machine must be de-energized and be protected against dust when the printer is not used for a long time.
