Hi, Bob! Unfortunately, I don't think KA has online manuals for machines KD-19 and older. Bastards.
And here's something else sinister! I was going through old parts diagrams, and the "cheapening" of the KDI-21 and KDC-21 machines I sort of ranted about in another thread (the 700W heating element used for water heating AND drying, the plastic fan duct, etc) which I had pinned on WP actually happened in mid 1985 on HOBART'S watch, and until the WP nomenclature ("KUDS"), they were known as KDI-21A and KDC-21A. Mid-1986 is when the Hobart name disappeared off the parts and service literature.
Does anyone know how WP came to acquire the KA division from Hobart? Was Hobart in dire straits? Did WP make a deal Hobart couldn't refuse? Was there dirty work afoot? Inquiring minds want to know!
