I have 2 Ryobi Weedeaters. Models 725r and 790r. I have looked for the numbers that match with the numbers listed on the parts breakdown. My 725r was bought as a reconditioned unit, and does not have any identifying labels. My 790r has a label on it that has the following information:
MOD 790R BLKDF
S/N 401009944 PPN500792
It also has 2 wing screws on the part that connects any accessories. I have looked at all of the part breakdowns and none of them has the same part.
Where can I find a parts breakdown for these units?
