I see many questions about these compressors and I've watched several videos on them. I've found this to be one of the more in informative videos. However, don't expect the video to cover all areas of the compressor. The presenter claims this is his second Yong Heng and he's discussing his experience with it after 26 months of use. The title says "update" and he references an earlier video so he likely has others still up on YouTube. https://www.youtube.com/watch?v=dP2BnDSPneI Hopefully some of you find it useful.
