I got one very old manual (pdf) for free but it's only a few pages (~30) and scanned VERY poorly as low quality jpegs so not text-searchable. Basically it was a waste of time.
I didn't get anywhere with those other guys since you seem to either be ignoring my request or refuse to give out their contact details for some reason and the guy I contacted wasn't very cooperative.
I solved the problem myself (also free) and this is a MUCH better solution too
I looked around for good quality manuals for the LR-15 without resorting to eBay and no such luck. I need a good parts manual and the electronics diagrams, etc.
I have one that's had some jibberish hackery done to it and I wanna try putting it back the way it was.
Had a very hard time with the door close sticking and the old yellow patt-lite sucks cause it doesn't come on with new bulbs in it.
isn't it better to ask local Okuma dealer for the diagrams and parts book? Any random diagram of that model lathe isn't accurate for your machine - they aren't equal.
