Hi @feinerl, have you gotten the manual yet? if you haven't, I'd recommend checking out a site like manualslib.com
manuals for a classic saw like the 084 can be tough to track down. You might be able to find a lot of the same information in the service manual for a similar model, like the 066 or even the 088. A lot of the teardown and reassembly procedures are the same across those old professional saws, so it could give you the info you need
