hello first of all im new here and im from germany so my english isnt so good.. i hope you guys can understand me.. i just got me a pfaff 145. i cleaned and oiled the whole machine. its workin very good now, but im not sure if its working like its supposed to work... there are two things im not sure about... 1. the middle foot always pulls the material (1mm) to the back before it pulls it forwards... i made little clip https://www.youtube.com/embed/IOTqViOSdbk 2 the handwheel always goes a little harder as usual when the outer foot starts to lift? is this normal? because on my adler 30-1 it almost feels the same... i think its because of the tension from the presser foot but im not sure.. i want to make sure im right greets
