I carefully threaded the needle and prepared to sew the hole in my son's jeans.
use a machine
The first thing you should do if the motor is turning, is check to see if your machine is threaded correctly. Then check to be sure your bobbin is in and threaded correctly. If it still won't sew, check both your upper and lower tension. Adjust until the stitches are even and tight, but not too tight. See related link below for more information on adjusting tension.

Sew
When using an overlocker machine, always keep your fingers away from the cutting blades and the needle area to prevent injury. Ensure that the machine is properly threaded and that the presser foot is lowered before starting to sew to avoid jams. Additionally, avoid wearing loose clothing or jewelry that could get caught in the machine. Finally, always unplug the machine when performing maintenance or changing threads.
