Before you can thread a Kenmore sewing machine, you need to wind the bobbin, or the bottom thread. Thankfully, most sewing machines can wind the bobbin automatically. The act of threading the top thread on the machine often involves little more than looping it through several thread guides and levers before inserting it into the eye of the needle. With a little time and practice, you'll be able to thread any Kenmore model with ease.
Wind the Bobbin
Place the spool of thread on one of the spool posts on top of the sewing machine. Pull thread from the spool and wrap it around the bobbin winding tension disc, located on top of the machine.
Bring the end of the thread through one of the holes on top of the bobbin and place the bobbin on the winding spindle, located on the top right of the sewing machine. Push the spindle to the right. It should click into place.
Turn the knob located inside the hand wheel on the side of the machine towards you until it clicks. Turning the knob will keep the needle from moving up and down when you wind the bobbin.
Turn the machine on and slowly push on the foot peddle to start the machine. The bobbin should spin and thread should wind around it. Hold the loose end of the thread with one hand until it snaps off to prevent it from tangling.
Pop the bobbin off the spindle once it is full of thread and cut thread to release it from the spool. Put the bobbin into the case and pull the thread through the slot on the case. Put the bobbin case into the shuttle, located under the needle. Push until the bobbin case locks in place. Turn the knob on the hand wheel away from you until it clicks.
Thread the Top Needle
Keep the spool of thread on the spool post. Turn the hand wheel towards you so that the needle is in its highest position. Raise the presser foot.
Pull the thread through the top thread guide, a small metal hook on top of the machine. Pull the thread down and around the tension area. The tension area may be a disc that you wrap the thread around or it may be a spring that catches the thread as you bring it up.
Slide the thread into the take up lever, working from right to the left. The take up lever is a metal loop that lifts and lowers when you turn the hand wheel.
Bring the thread down and slide it into the thread guide next to the needle. The needle's thread guide is a small wire loop on the left side of the needle. Insert the thread into the eye of needle, threading it through from the front of the machine to the back.
Hold the thread in one hand and turn the hand wheel towards you with the other. The needle will lower into the machine and catch the bobbin thread, bringing it back up with it. Lift up the top thread to bring the piece of bobbin thread all the way out of the machine. Trim the thread tails so that they both measure about 4 inches.
