Im looking for a user manual or instructions for my old pfaff Hobby 4260 sewing machine

Are you sure of the model number? Pfaff doesn't have a Tiptronic 1020, just a Hobby 1020. The manual for the Hobby 1020 is not on the Pfaff site: http://www.pfaff.com/en-US/Support-and-Updates/Support . There is a Tiptronic 2010 and that manual is here: http://www.pfaff.com/SiteMedia/PFAFF/Products/Machines/Support-manuals/Tiptronic_2010_2020-manual-EN.pdf?ext=.pdf . Some sewing machine parts vendors do offer the manuals for sale.

One source of the manual for the Hobby 1020 is https://www.sew4less.com/product/2072/Pfaff_Hobby_1020_Instruction_Manual . This store has the manuals for the Hobby 1020 and the Tiptronic 2010 is http://www.pfaffmanuals.com/Pfaff_Instruction_Manuals.htm . For the Tiptronic 2010 manual, another source is https://www.performancesewing.com/partsdatabase/instruction-books/pfaff-2010-manual.htm .

I hope this helps.

I would suggest that you call pfaff because if you do not have a pfaff dealer where you live then you will have to pack it up and ship it to a pfaff dealer that is near to you. Good luck oh and make sure to insure it. Hope that helps

Here's a manual for your machine.

Download the users manual here if you don't have one. PFAFF users manual.

it sounds like the buttonhole mechanism is seized up or gummed up with old grease. try following the linkages for buttonhole mechanism or button to see you can locate the stuck linkage.

otherwise it sounds like a tech job.
