Precaution: Before replacing this part, wait for the print head temperature to cool down to room temperature before starting the operation to prevent burns.
Before proceeding with the replacement, make sure to turn off the printer and disconnect the power to ensure safe operations.
Rotate the left Z-axis motor coupling clockwise to lift the Z-axis to the middle position as shown in the diagram below.
After the print head has completely cooled down, use your hand to pull the silicone sleeve off the hot end downward.
