I recently acquired a Griggio PF 400 Jointer (was actually at a scrappers). I bought it for $440! I am now cleaning it up as it was outside in rain over about 3-4 days from what the scrapper told me (was just removed from a working shop that closed). I have searched and have seen a couple old posts on the Jointer. Wondering if anyone might have a manual they can send or to point me in the right direction. The tables are not adjusting and I believe will have to take them apart to clean everything up, to free them up. It's a 1985 model, 6.6hp 3-phase motor. I has a 5 blade cutter head. Any info / insites into this jointer I would appreciate it. As Griggio shutdown several years ago. So no information from them is available as far as I know.
