Check the conditions alongside each answer. Foot attachment, shank type and adapter requirements are separate; one does not establish universal accessory fit.
Presser feet and adapters
How do ordinary presser feet attach?
conditional
Native snap-on feet. Ordinary feet snap onto the presser-foot holder.
Raise the needle before changing the foot. Align the foot pin with the holder and lower the lifter. This establishes foot-to-holder attachment only.
Which Singer needle types and sizes does the manual list?
conditional
Singer 2020 needles: 11/80, 14/90, 16/100 and 18/110 for woven fabrics; Singer 2045: 11/80, 14/90 and 16/100 for knits.
Choose the type and size using the manual's fabric-weight and thread table. These are source-native Singer needle codes, not a normalized universal system claim.
Which way should bobbin thread unwind?: Place the bobbin in its case with the thread running clockwise.
Hold the bobbin in your right hand with the thread running clockwise.
Pull the thread through the slit in the case and then underneath the flat tension spring.
How is the bobbin case installed?: Install the case with its locating pin straight up and the thread toward you.
Hold the latch open, with locating pin straight up.
Slide the bobbin case onto the center spindle of the shuttle, with the thread toward you.
Be sure the locating pin fits into the locating groove at the top of the shuttle.
Which way does the needle face?: Insert the needle with its flat side toward the back and push it fully upward.
Always disconnect the machine from power supply
Insert the new needle into the needle clamp with the flat side toward the back.
Push the needle up as far as it can go.
How is the shuttle area cleaned?: Remove the bobbin case, move the two shuttle keepers aside, and remove the race cover and shuttle before brushing the feed dogs and shuttle area.
Where does the owner manual specify oil?: Apply one drop of sewing-machine oil to the shuttle center pin and shuttle race where indicated.
Remove the bobbin case from the shuttle.
Push aside the two shuttle keepers.
Remove the shuttle race cover and shuttle.
Clean the feed dogs and shuttle area with the lint brush.
Put a drop of sewing machine oil on the center pin of the shuttle and shuttle race
Which Singer needle types and sizes does the manual list?: Singer 2020 needles: 11/80, 14/90, 16/100 and 18/110 for woven fabrics; Singer 2045: 11/80, 14/90 and 16/100 for knits.

Which stitch settings can be adjusted?: Stitch length, stitch width and straight-stitch needle position can be adjusted with the control-panel buttons.
You can manually change the length, width or needle position for straight stitch
Some patterns offer more options for manual adjustments than others.

Multiple cited representations for one field share one row. SewGraph preserves every value and exact proof passage; it does not guess which representation is “raw” or “normalized” when the public projection does not label that distinction.
