Drum removal question

Probably dumb question but after searching couldnt find anywhere which direction the adjuster should be turned with my flatblat screwdriver. This is for a 9" front driver side drum. Before disassembly the drum was seizing on very light pressure. Manual stock drum brakes.

Do I insert it down and rotate it upwards in the same way a bolt would need to be turned to get it to rotate away (lefty losey rule) ? It's stubborn and doesn't want to rotate much right now so gonna soak it in PB blaster for the day before I get a chance to try again tonight
