I have an Olivetti Model 21 (basically a Studio 44) that I have de-gunked and cleaned, but have yet to oil. The problem is, I don’t know where to apply oil. I have cleaned up a few machines, but have hesitated to oil them in fear of putting too much, or in the wrong places. I’ve heard from more than one person to never oil the segment (the semi circle where all the type bars are attached), but I have no idea about anything else.
The Oli has a heavy action, and I’m wondering if it’s because I have never oiled the machine. Anybody out there done this before?
