Although I have the manual that came with my F4, I wanted to download the manual in pdf form to my computer so I could read it anytime I was using my computer. I have downloaded it from the Fisher website & other places and every time I get the same results - it is not the full manual only part of it. I think that maybe Fisher left out some of the file or it is something with my computer. It is 1.52MB in size. Here is the file http://www.fisherlab.com/hobby/documents/Manuals_FISHER/F4manual.pdf One of the dealers here on this forum I think Richard, was kind enough to scan one of his manuals and email it to me but somehow it got deleted off my computer. Thanks! Steve.
