Identity verified · evidence for each answer

Using and maintaining this machine

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

With power off, place the ordinary foot below its holder and lower the holder until its opening is above the foot pin; the foot engages automatically. To remove it, raise the foot with the presser-foot lifter and press the holder release lever.

  • This is the source-named attachment procedure. It does not establish a standardized shank class, universal foot fit, or adapter compatibility.

Source evidence · 1 unique proof passage: Profile Proof E1

Bobbins and hook

How is a bobbin wound?

conditional

Route the thread through the bobbin guide and clockwise around the tension discs, thread the bobbin, move its spindle right, wind to the automatic stop, then move the spindle left and remove the bobbin.

  • This sequence applies only to the exact models printed on the shared manual; it does not establish bobbin equivalence or class.

Source evidence · 1 unique proof passage: Profile Proof E2

How is the bobbin inserted?

conditional

With the needle fully raised and power off, insert the bobbin so it turns counterclockwise, route the thread through the case tension path, leave about 15 cm, and replace the cover.

  • The direction and routing procedure do not establish a standardized bobbin class or hook system.

Source evidence · 1 unique proof passage: Profile Proof E3

Needles and threading

Which needle types apply?

conditional

The OEM table assigns SINGER 2020 sharp needles to natural-fiber fabrics and SINGER 2045 ball-point needles to knits and stretch fabrics, including natural and synthetic fibers. It explicitly does not recommend 2020 for stretch fabrics.

  • The 2020 choice is explicitly not recommended for stretch fabrics. These are conditional alternatives, not one universal machine-wide needle type. Match size to fabric and thread.; Needle choice depends on fabric and thread. The printed table contains inconsistent size conversions (16/100 versus16/110); no universal size range or corrected conversion is asserted here.

Source evidence · 1 unique proof passage: Profile Proof E4

Which way does the needle face?

conditional

Insert the needle as far upward as possible with the flat side of its shaft facing the back, then tighten the clamp screw.

  • Switch off the machine before changing the needle.

Source evidence · 1 unique proof passage: Profile Proof E5

Care and ownership

How should the machine be cleaned?

conditional

Power off and unplug the machine, remove the needle plate and bobbin case as shown, brush the feed teeth and inside of the bobbin-case area, then reinstall the case and plate in the documented position.

  • Follow the manual's illustrated removal and reassembly order; the extraction does not support an added oiling instruction.
