Sounds like as the machine builds up friction from extended use, some vital part is lacking lubrication and is seizing up. A good service person will remove ALL of the covers and thoroughly air clean and oil every moving part. Sometimes these dry points are hard to find and patience is required.

You can get a sewing machine oiler with a long applicator and put a drop of oil on anything that moves, but over oiling can be messy.

SOURCE: What needle type is used for the juki ddl 555?

Regular sewing machine needles. Choose the needle type and size according to the type fabric or thread being used.
