Help with German Klopp shaper wiring

I picked up a Klopp 450 a while back. Got around to trying to get the motor working the other day. It has a 14-30 Nema 220v single phase, plug on it when I got it. I plugged it in and it runs very slow. Hardly starts without help. It is a 2 speed motor with 2 speed switch. The motor is wired for 220v on the motor posts.

I would ask if anyone knows how to read German, if they could decipher the motor plate s little. I know its 220/440v, 1.1 kw, RPMs and ramps, but not sure about "1.5 P.S." and if there is a significance to the "0.82 Cos" assuming that's Cosign. There is nothing I can see designating it as a 1 or 3 phase.

There is also a safety on/off switch on the side of the machine that the plug is wired into. It is currently wired as a "2 phase" according to the GE switch. Poles marked L1, L2, L3, with "phase 1" showing L1, and "Phase 2" on L3. It is currently wired with L1, and L2 have the hot wires and L3 has the neutral. I'm wondering if "L3, Phase2" should be the hot lead and L2 the neutral. It is currently wired closest to the center wiring diagram.

It probably came from a shop that had a 3 phase service with 1 phase grounded.
It was common years ago. Single phase breaker boxes were used.

I'm starting to think you may be right that it is wired for 3 phase. The two speed motor has 9 posts on each side totaling 18 posts. They are correctly wired for 220v, other than 18 posts, haven't found anything to indicate one way or the other.

Found this under the motor cover. Along with a photo of the current wiring. I'm starting to think that it is a 3 phase machine that they used a 14-30 plug with to run the 3 phase through.

Saying it is 3 phase, I could then just swap out the plug, plug into my 3 phase and go to town?

No other opinions?

The obvious check is to insure that all 3 phases are not grounded anywhere inside the machine before applying power.

Thanks, I'm going to give it a good once over, cross reference it with my 3 phase 2 speed drill press and if all looks kosher, give it a try. I'm hoping someone ether used that plug as a 3 phase plug, or installed the plug thinking it was single phase, and then gave up.

Turns out it was 3 phase, a plug swap and it was an easy fix. The wiring diagram under the switch plate showed 3 power lines in. Now I need to reverse a couple wires to get both speeds turning in the same direction.
