I bought a used Danuser F-8 post hole digger from a friend, and he bought it used, and who knows how many other people have owned this thing. I'm looking for an owner's manual to be sure I'm not doing anything wrong when I operate it. I found a parts manual and believe I need to replace the PTO input shaft bearings and seal. One of my questions is what type of lube goes in the gearbox? I put in some heavy weight gear oil, but there was a small note on the Danuser site about using grease when reassembling the gearbox after doing an upgrade from older models. I don't know if this means I should also be using grease, or gear lube. If I use grease, it will cure my leaky PTO seal, or at least make it so I don't have to keep filling the gearbox every few hours.
The Danuser web site does not have an owner's manual available for download, which is weird because all kinds of other things can be downloaded.
