That lever under the machine is called a knee lever. On many machines, the foot pedal is inside the cabinet, in a bracket that is activated by the knee lever. I'm not familiar with the specific machine you have, but on some machines you can push the foot pedal (also called a controller) out of the bracket and use it as a regular foot pedal.
That's your first step - figure out how what makes it run. The next step find a manual for it. Then, to oil and grease it. You'll need some sewing machine oil. It's generally available at any place they sell fabric. The gears will need grease.
I have no idea how to use a phone on this (or "any") site. You attach a photo on a computer by going down below (on a reply page) where is says "attach files". I'd try that and see if it works on a phone, as we really need a photo to figure out what machine you have and give good advice.
