sewing machine oil - only
Definitely no WD-40 or 3-in-1 oil. Tri-Flow is okay for older vintage machines with all metal gears, but I would not let it near the Bernina 180. I would research before using it on a vintage Bernina, mostly because of the nylon gears. I only use it on my vintage Singers.
Tri-Flow has Teflon in it, IIRC. That vintage Bernina Yahoo group has had discussions on Tri-Flow from time to time. Sewing machine oil ~only~ for the computerized/electronic Berninas. It can be any reputable brand sewing machine oil, but please not a rubbish brand.
Depending on which format the 180 "reads" (.EXP or .ART), if it is .EXP you could buy the Embird basic software from that web site. (Embird can not save in .ART format, the proprietary format of Bernina) Embird's Basic package is inexpensive and then there are add-ons, a la carte.
There is a free download of ArtLink or somesuch version from Bernina's web site, but sometimes the newer softwares will not play nice with an older machine. Check with your dealer because I could very well be wrong about this.
Machine embroidery is an expensive hobby, all the stabilizers, purchase of designs, some sort of software, etc. etc. etc. You might be happy just using it as a sewing machine and have a bit of luck trying to sell of the embroidery module & hoops. And a fine sewing machine it is.
We see guys, from time to time, in the machine embroidery classes at the local sewing dealer. No big deal. Some of the best quilters and machine embroidery artists in the U.S. are men.
