My binder still has about every document warranty card for every item even stuff that's gone like Sony disc changer and Sony Trinatron TVs. If you don't have a good binder or file on phone ,PC ect. Start by the build sheet model #s, put pdf at the end works a lot of times. I have downloaded and printed generator repair and parts manual any other thing I run across and bookmarked tons of links and pdfs shared here.
See if instructions are in here.
