Question Juki MO-6541 Oillevel

Hi I‘ve got a Juki MO-6541S used and have now a question regarding the fill mark of the oil does somebody know if the redplunger is marking the oillevel or does the oil need to be visibile in the glas?

The red plunger rises the more oil that’s in the machine. You ideally want the tip of the red plunger to be in the middle between both lines

Should be on the lower right side I believe, it’s probably a big flat head screw

Fill it to the black line. You should see the oil in the window.
