ユーザーズガイド、HiTorque ミニミル、エアスプリング付きソリッドコラム、3990

I was glad to have the manual printed out rather than just downloading it—the paper is thick enough that it won't tear easily on the shop bench. The section on setting up the air spring column clarified a few details I'd been guessing at.

The printed manual arrived in perfect condition and the section on setting the air spring preload was much clearer than trying to read a PDF on my phone. Having a physical copy to flip through while actually working at the mill saved me a lot of time.

I was a bit skeptical about paying for a printed manual when the PDF is free, but having the spiral-bound copy on my workbench is actually way more convenient for flipping through while setting up the air spring. The diagrams are clear and it covers everything from assembly to troubleshooting.
