211W155 Marking Leather

[HH Supply]

Hey Everyone!

I tried searching but was unable to find what I was looking for. I’m hoping someone can help me understand some adjustments on a Singer 211W155 machine. 
 

I picked up this machine with a table and an already installed Sailrite Workhorse for $300. It was a deal I couldn’t pass up as my first machine to help me learn and speed up production over hand stitching. It runs great! The only problem I’m having is that it’s marring up the leather pretty bad. 
 

I’m going to apologize in advance for using descriptions of parts as I’m still learning the correct terminology as well. 
 

The part leaving a mark is the foot that the needle actually passes through. It’s a smooth bottom foot but when slowly moving the hand wheel, I can see this foot is pushing up tight against the feed dog with no space. If I run it with no material, I can even hear the feed dog click against it metal to metal. The pressure of this foot to feed dog is causing my marking. 
 

how can I relieve this pressure and raise this foot or allow for the spring pressure on this to be less intense so that it still feeds correctly, but it doesn’t smash my leather into oblivion and mar it to hades?

Do you mind posting a photo of the top of your machine?

there either is a big thumb screw OR a slotted screw (flush with the lid or a bit deeper) in about the same spot for adjusting the foot pressure. But if you dial in a too low foot pressure the friction between needle and leather may lift your sewing material when the needle bar is rising.
