Looking for help with a Wilson Rockwell tester.

I was a real idiot this morning. I was using a Rockwell tester while taking to someone today, I ran the test first in the correct fashion. Then I automatically depressed the lever again to begin the test again. Then I panicked realizing what I had done, and I quickly turned the screw than controls the elevation of the specimen down, and then removed the specimen before the test was completed.

Now whenever i raise a part to the test head and attempt to apply the minor load/zero the dial, the screw that raises the part locks up as soon as the specimen touches the test head.

To be clear, the normal procedure is:

1. Place part on the anvil
2. Raise part to penetrator, then continue until small pointer on dial is vertical
3. Zero dial
4. Pull depressor handle
5. Wait until dial stops moving
6. Pull handle to the right of machine for results.

I did 1-6, and got a weird result as the indicator did a couple loops around the dial. Then without thinking I hit the depressor handle again, then quicky lowered the part, interrupting the test.

So that’s where I’m at. I’ve gotten a copy of the manual and I’m going through it, but I was hoping someone here might be able to help me out.
