Just gonna echo some stuff:

Quoted from Cheddar:

That plunger shouldn't be pulled in but the arm could be stuck as detailed above.

This is correct - coil looks okay (from this angle), so I'd wager, if stepping up...

Quoted from zacaj:

So to step it up just use the other coil on the mech to step it up. At that point the small coil should move out and can then be pushed to step back down

should move the ratchet arm up and out of the way. If you examine the gear that the arms press against when you move the coil plungers, you should see the mechanical reason why the ratchet arm may or may not be moving. If there's no impediment to moving the arm, then there is dried grease or something on there. The ratchet arms are the reason why you may or may not be able to twist the 'spider' fingers or circular wiper discs from the front, btw.

Quoted from BleacherBum:

Good luck with your Pat Hand. I found this to be a fun game.

I didn't think much of the layout before I repaired one, but was pleasantly surprised by how fun the game was.
