Simple check of timer and irradiation time settings, etc. There are two types of irradiation lenses (images 4/6). Each setting seems to be functioning. The arm also moves. Requires specialized knowledge. We would like to request purchase by a professional. Note: We do not accept any claims after purchase. After purchase, please be at the buyer's own risk. Please purchase after understanding the above. I do not have specialized knowledge, so I cannot perform detailed checks. Please judge the condition from the images. Since it is a used item, there are scratches, dirt, rust, and paint剥げ (peeling). Image 2 shows the residue of masking tape, which I left as is because I judged that forcibly removing it would cause scratches. Accessories are as shown in the images. I do not know the usage time. Since cleaning has not been done, please judge the condition by looking at the images. No claims, no returns. Not recommended for those who are sensitive. ☺︎ Feel free to negotiate the price ☺︎ * Shipping will be 3-7 days after purchase as it takes time to pack. Packing will be only with air packing material as there is no box. The casters will be shipped in a bare state to facilitate movement. We would like to request purchase by those who understand the above.
