Presser foot does not lower and when raising foot, lever feels tight. Have oiled part. Does not help. If left long enough, about 5 minutes, presser foot will lower.

Hi, Don’t know about this machine but here’s the presser foot section from the service manual for a Bernini 930 that may help you to see what’s going on. To check if the adjustment on your machine is correct you may have to improvise as I cannot find the “feeler gauge” mentioned in the manual but maybe you can place a 7.5mm object under the presser foot as described. Sorry that I can’t be of more help on this.
