- When the oil cup in the oil cup is filled with oil cup clean line, please clean the oil cup in time. The oil cup disassembly is as follows: hold the lower part of the oil cup with both hands, and remove the oil cup horizontally; After cleaning, install the oil cup in reverse order.(the oil cup is longer, please keep the level when the oil cup is removed so as not to overflow the oil.)

- Regularly replace the filter cotton. The attachment is equipped with 5 filter cotton for replacement. In order to ensure better steam cleaning effect, a replacement can be made every two years. Replace the filter cotton: open an Angle according to the direction on the lid of the water cup, then take out the water cup cover along the vertical direction. Remove the filter cotton at the filter junction.

- When the lighting is needed (by professionals), please remove the power plug first. Insert a small screwdriver into the gap between the lamp and the guide plate and gently pry open and remove the lamp. Replace the new lamps with the same specifications and install them in the mounting holes of the guide plate.
