White family Rotary
 

Seeking information on my White Family Rotary
I don’t know how to lift the machine to get under it so I can clean
Year made and a missing plate to find
thank you for your help and advice

Welcome to Quilting Board.

I believe that you machine will not take what is called a t-shirt plate. I'm not sure what the rectangular White plate looks like on the underside.

I think that the knob on the right side of the bed is what needs to be turned to release the head to raise it. Is the spring belt off the treadle fly wheel?

I have written several posts about White rotary sewing machines with several links to manuals, additional info and instructions for threading, both upper and lower. A couple of which are https://www.quiltingboard.com/7864633-post2.html and https://www.quiltingboard.com/8492340-post3.html

Hope something in the above links are helpful with what you are looking for.

Janey, Right on!

I may be wrong but I believe you push to the left or right (not spin) the knob at the front right near where the drive belt enters the wood cabinet. While pushing the knob push the machine away from you to access the bottom and clean or lube it.
