most important on deco is one drop of oil every day between hook and bobbin case,best to do without to much hassle is if you remove the plastic slide plate you will see a place on lh side where there are a couple of slots like cut out,put drop of oil between slots and you will see when moving handwheel oil will reach the hook area.just remember service on embroidery machine as well as good cotton and good qaulity needle is very important for nice results
