This is a parts list for the SR500/SR400. Although it is a parts list, it contains detailed exploded diagrams, and I think it can be used as a service manual or maintenance manual. There is some wear and tear, but there is no [erasure of characters] due to oil, nor [missing pages] due to tearing, which would cause problems in use. Parts lists and service manuals are very helpful when performing maintenance♪ Please use it as a companion during maintenance!
