When I begin sewing everything seems normal but after a few minutes the needle speed decreases gradually and eventually stops. It smells like burning rubber. This machine is only foot pedal controlled (I think).
I am searching for similar answers and the answer above seems extreme. I would think its possible you can burn up bearings, but what about the belt first? (hence rubber smell), sounds it's too tight, like other's answer.
When was the last time you oiled it?
Sewing machines need regular oiling as you use them - it sounds like you have or are close to seizing the bearings.
In future, when you smell burning and a machine that should operate at full speed slows down - stop, don't persist in using it.
It clearly has something wrong with it.
Your users manual should cover oiling the machine - there are predetermined points at which you drop the sewing machine or 3-in-1 oil into. Only a few drops are necessary, but you should oil it every few hours of use.
I did not see in the user manual where this function will occur automatically ... the button needs to be pushed manually288 views
