I'm struggling to find a replacement guide anywhere online unfortunately.
However, I did find that your model is associated with a recall for which you may be eligible to receive a replacement from Cosori at no cost: https://www.cpsc.gov/Recalls/2023/Two-Million-COSORI-Air-Fryers-Recalled-by-Atekcity-Due-to-Fire-and-Burn-Hazards
If you decide to get a replacement or take advantage of the recall, take it apart and make a guide for the next consumer!
