OTC 4000 user directions

The book's about an inch thick. That and the fact that most of the operations to be able to use it for racing (which it was never meant to do) are undocumented procedures. I have a practically new one in the case, I don't even use anymore because I've forgotten most of the "special" steps.

That and the fact that it's an incredibly antiquated piece. Great for in the driveway troubleshooting, but sucks for performace monitoring!
