I wasn’t going to include this in my recap but a reader insisted that the weird books I consume is one of the unexpected joys he gets when perusing the site (which apparently can get kind of “stuffy” with all the high-falutin’ literature or grim liberal non-fiction), so here you go. I got this repair manual as a way to bolster my knowledge after acquiring a gorgeous 1965 Olympia SM9 typewriter that types like a dream. It covers the basics on what parts are called and what they do, and how to go about troubleshooting. #1 tip is to keep your machine covered so dust doesn’t muck up the innards.
This section below is probably my favorite part of the manual, with frank guidance about how you can use this book to create your very own typewriter repair business. Yes, this was published in 1981.
