Hi & welcome to the QB from Texas.
Here's some info on the Model SL2110 that was talked about here on the Quilting Board in 2015. Hope this helps you out. Looks like you've got all the parts & pieces including the manual & the cams.

Thanks, osewme! Unfortunately the suggested manual in that other thread was for a machine that is very similar but not the same, especially regarding pattern cams and buttonhole making.
So I am still hoping someone who has the Koyo Dial n Sew Model SL2110 manual can share it with me.

I'm glad to find QB regardless, it seems like a great community!

Owners Manual Dial n' Sew 3110
 

I have recently acquired this machine and am VERY excited to use it. But, it didn't come with any type of manual and I LOVE owners manuals. I keep all of them even when I'm very familiar with the appliance, etc.

Has anyone posted images of their manual? I'm willing to purchase a complete set of photos from someone, if they are will to post for or email to me.

New here! Thank you for reading :)
