Oiling on Bernette (Ellen G)

[@BreadNButterArt]

Hi, I have 2 vintage sergers. Would you mind instructing me how to remove the plastic front/face cover plate (where the tension dials are attached to) so I can do a more thoural cleaning & oiling? I have only been able to take off the bottom plate. I have taken every screw that I can see that are attached to the cover plates, but no other plates are coming off. It looks like the front plate should come off next. I don't want to force & break it. Thank you.
