Native snap-on feet. With power off and unplugged, raise the presser foot, turn the handwheel toward you until the needles are at their highest position, then press the white release button on the back of the presser-foot bar to remove the foot. Place the replacement foot pin directly under the ankle groove, lower the presser foot, and press the button so the foot snaps into place.
This proves only the documented foot-to-ankle pin/groove procedure; low-shank naming and optional or third-party foot fit remain unknown.
Start from the factory normal-condition pressure; turn the adjustment tool counter-clockwise for less pressure or clockwise for more, and always test on a sample before the garment.
Adjustment is only recommended when the fabric result requires it; the manual does not prescribe one universal pressure setting.
Turn power off and unplug, raise the needles fully, insert the left and/or right needle as far as it will go with the flat surface to the back, then securely tighten the corresponding clamp screw.
Use one or two needles as required by the selected stitch; preserve the exact manual's needle-system requirement.
Use 1.0 for normal fabric, move between 1.0 and 2.0 for stretch fabrics, or between 0.7 and 1.0 for lightweight fabrics, then test-sew for the material and desired result.
The setting depends on the fabric and desired result; test-sew before the project or garment.
Turn power off and unplug, open the front cover, and remove lint with the accessory lint brush; overlock cutting produces enough lint to require more frequent maintenance than a conventional machine.
The machine must be off and unplugged before cleaning.
With the left needle or both needles, the nominal width is 5.7 mm. With only the left needle, the cutting-width adjustment range is 5.2–6.7 mm. With only the right needle, nominal width is 3.5 mm and the range is 3.0–4.5 mm.
Width depends on needle position and fine adjustment with the cutting-width knob; plate graduations are a guideline.
Which needle system applies?: Use SINGER Overlock Needles, Style 2022; the specification lists size 14/90, while the fabric table also conditions 12/80 by fabric weight.
Which needle sizes apply by fabric?: The fabric table lists 12/80 for light fabric, 12/80 or 14/90 for medium fabric, and 14/90 for heavy fabric.
What is the maximum sewing speed?: Maximum sewing speed is 1,300 stitches per minute.
How should differential feed be set?: Use 1.0 for normal fabric, move between 1.0 and 2.0 for stretch fabrics, or between 0.7 and 1.0 for lightweight fabrics, then test-sew for the material and desired result.
set the differential feed adjusting lever to 1.0
number between 1.0 and 2.0

How should presser-foot pressure be adjusted?: Start from the factory normal-condition pressure; turn the adjustment tool counter-clockwise for less pressure or clockwise for more, and always test on a sample before the garment.
What overlock widths are supported?: With the left needle or both needles, the nominal width is 5.7 mm. With only the left needle, the cutting-width adjustment range is 5.2–6.7 mm. With only the right needle, nominal width is 3.5 mm and the range is 3.0–4.5 mm.

When only the left needle, or when both needles are used the stitch width is 5.7 mm.
When only the right needle is used the stitch width is 3.5 mm.
When only the left needle is used: 5.2 - 6.7 mm
When only the right needle is used: 3.0 - 4.5 mm
How should lint be cleaned out?: Turn power off and unplug, open the front cover, and remove lint with the accessory lint brush; overlock cutting produces enough lint to require more frequent maintenance than a conventional machine.
What owner oiling is required?: Turn power off and unplug, lubricate the diagram-marked moving parts often with sewing-machine oil, then wipe away excess oil before sewing.
An overlock requires more frequent maintenance
Turn off the main power switch and unplug the machine.
remove all the lint using the lint brush
must be lubricated often
Use sewing machine oil. Do not use any other oil
remove all excess oil before sewing
How does the ordinary overlock foot attach?: With power off and unplugged, raise the presser foot, turn the handwheel toward you until the needles are at their highest position, then press the white release button on the back of the presser-foot bar to remove the foot. Place the replacement foot pin directly under the ankle groove, lower the presser foot, and press the button so the foot snaps into place.
How should the needles be installed?: Turn power off and unplug, raise the needles fully, insert the left and/or right needle as far as it will go with the flat surface to the back, then securely tighten the corresponding clamp screw.
Turn off the main power switch and unplug the machine.

Can the machine sew with the front cover open?: The safety switch prevents the machine from sewing while the front cover is open, even if the foot control is pressed.
Specifications vary from country to country.
Use the foot control to adjust the sewing speed.
When the front cover is open the safety switch is activated and prevents the machine from sewing
