Singer 438, 3116 Instruction Manual

To thread the Singer 438, place the spool on the spool pin, draw the thread through the thread guide, then down around the tension discs, back up through the take-up lever, and finally through the needle eye from front to back.
Check if the needle is inserted correctly and ensure it is appropriate for the fabric. Also, make sure the needle is not bent and that the machine is threaded properly.
Regularly clean the machine by removing lint from the bobbin area and feed dogs using a brush. Oil the moving parts as recommended in the user manual and ensure the machine is covered when not in use.
Skipped stitches can be caused by a dull or bent needle, incorrect threading, or incorrect tension settings. Ensure the needle is suitable for the fabric and replace it if necessary.
Adjust the tension by turning the tension dial located on the front of the machine. Higher numbers increase tension, while lower numbers decrease it. Test on a scrap fabric to find the right setting.
