Question 1

How do I use the automatic needle threader on my Singer Model 1120?

Accepted Answer

First, raise the needle to its highest position and press lever (A) down as far as it will go. The threader will automatically swing to the threading position (B). Pass thread around guide (C), then pass the thread in front of the needle around the hook (D) from bottom to top. Release lever (A) and pull the thread through the needle eye. Remember to turn the power switch to 'O' (off) when performing these operations.

Accepted Answer

The basic upper thread tension setting is '4', which is appropriate for all stitch functions. To increase tension, turn the dial to the next number up; to reduce tension, turn it to the next number down. For the lower thread tension, the bobbin case should unwind about 1-2 inches when suspended by the thread if tension is correct. Adjust the screw on the side of the bobbin case if needed.

Question 3

How do I troubleshoot skipped stitches on my Singer Model 1120?

Accepted Answer

Skipped stitches are typically caused by an incorrect needle, bent needle, needle inserted incorrectly, improper threading, or wrong needle/fabric combination. To fix this, change the needle, re-thread the machine, and ensure you are using the correct needle type for your fabric.

Question 4

What should I do if the upper thread keeps breaking on my Singer Model 1120?

Accepted Answer

Upper thread breakage can result from improper threading, tension that is too tight, poor quality thread, a bent needle, or a burr on the needle plate. To resolve this, re-thread the machine, adjust the upper tension to a lower setting, use good quality thread, change the needle, and check the needle plate for any damage.

Accepted Answer

Always unplug the machine before cleaning. Remove the needle plate and clean out any lint or dust accumulation in the bobbin area with a brush. Wipe the exterior of the machine with a soft, dry cloth and do not use harsh chemicals or abrasive cleaners. The machine is designed to require minimal lubrication; over-oiling can attract dust and lint.

Always read all instructions before using the machine. Keep fingers away from all moving parts, especially the needle. Use the proper needle plate to avoid needle breakage, and do not pull or push fabric while stitching. Always turn the power switch to 'O' (off) when making adjustments in the needle area, and unplug the machine when removing covers or lubricating.

Question 7

How do I raise the bobbin thread on my Singer Model 1120?

Accepted Answer

Hold the upper thread with your left hand and turn the handwheel (1) towards you (counterclockwise), lowering then raising the needle. Gently pull on the upper thread to bring the bobbin thread up through the needle plate hole (2). Then lay both threads to the back under the presser foot (3).

Question 8

How do I fix fabric puckering on my Singer Model 1120?

Question 15

How should I handle fabric while stitching to avoid damaging the needle?

Never pull or push fabric while stitching, as it may deflect the needle and cause it to break. Additionally, keep your fingers away from all moving parts, especially around the sewing needle. Always use the proper needle plate, as the wrong plate can also cause the needle to break.

Question 16

How do I check and adjust the lower thread tension?

Accepted Answer

Remove the bobbin case and bobbin, then hold it by suspending it by the thread. Jerk it once or twice—the thread should unwind about an inch or two.
