Pressure foot will not lift up - Juki DDL-8700

Do u have an automatic machine meaning ft is lifted by pressing ft pedal a certain dirtection. otherwise tilt machine and push knee lever. there should be a flat oval piece on top of lever rod. does it rise straight? it needs to contact the push rod on the machine presser ft. see if the line up by lowering the machine slightly. if not bend rod to aglin. your knee lift may need adjustment too and maybe the presser ft screw located by removing the rubber plug on side of machine or take off the plate by removing 3 screws. careful with gasket cause machine will leak if u tear gasket.. presser ft screw is easy to find. lower ft and tighten. make sure that the needle is centered in foot slot when adjusting presser ft screw. otherwise thread will break when needle hits side of presser ft. a very common problem that many do know about and someday i will charge the site. 35 years with juki and still going strong.
