Sorry if it's already here somewhere, I couldn't find the answer searching.
I just got my first Pachislo machine and after cleaning the sensors and replacing the stop board I finally got it working!

Just a couple things I can't seem to figure out.
1 - The spin reel knob doesn't already reset and I have to move it up before the reel stop buttons light up. Is there a good way to clean these or just a replacement?
2 - Is there any way to turn credit mode off where the coins drop when you win?

Thanks for any help you can give a new guy.
