Locate the presser foot lift lever at the back of the machine near the end of the sewing arm. My thumb is on it in the photo.
The foot lever is in the lowered position here:
Lift the foot lever. This opens the thread tension to make threading easier. Here the lever is in the up position.
Choose thread & grab an empty bobbin to fill with bottom thread.
Place Thread Spool on Pin at back of Sewing Machine.
Place your empty bobbin on the winding pin at the top right hand side of the sewing machine and push the fill tab over the base of the bobbin.
Pull thread across from right to left.
Pull thread clockwise around the winding thread guide like this.
Wind thread clockwise around the bobbin a few times so it bites down on itself.
Disengage the sewing arm from the motor by turning this inside wheel counter clockwise. This will allow the motor to wind the bobbin instead of working the needle up and down.
Use the motor (foot peddle) to wind bobbin. Bobbin Fill Lever will auto disengage when the bobbin is full. (I ran out of gold top stitch thread and had to switch to blue for this step) Sorry ;)
Clip thread and remove the bobbin.
Set bobbin, now full of bottom thread, aside.
Remember to engage the motor to the sewing needle by turning the inside wheel back clockwise this time.
Again pull thread from right to left to begin threading the needle with top thread.
Find this first thread guide on the back of the machine above the foot lever we lifted earlier.
Pull it under the arm until it's through the guide. Like this.
Pull thread through the thread tension disks inside this slot. If you raised the foot lever this should be easy and they will not pull against the thread.
Do you see the thread coming out of the Tension Slot?
Here it is.
Pull thread down to the 2nd thread guide. (Just above my index finger)
Pull from right to left.
Pull thread up to the sliding guide which should be in the up position. If it's not up, use the larger hand wheel on the right side of the machine to raise it. Always turn this counter clockwise.
Here is the thread going through the sliding guide.
Pull thread down to the left side of the needle thread guide & place it behind.
Insert your needle with this flat side facing away from you toward the back of the machine.
Use this knob to tighten the needle in place.
Insert a needle threader into the eye of the needle from back to front.
Push the thread through the threader.
Pull the threader out bringing the thread through the eye of the needle.
From front to back.
Choose your presser foot.
Fit the open end of the foot over a small cone shaped head on the foot arm.
Secure the foot to the foot arm by lowering this small catch lever.
Pull top thread under foot and to the back of your machine.
Open the bobbin case under the feed dogs. (Those little metal teeth under the presser foot)
Pull a small lever on the bobbin case from left to right to disengage it from the sewing machine & pull the bobbin case out.
Hold your bobbin like this with the end of thread facing you.
Place the bobbin into the bobbin case with the thread end sticking out.
You'll see a small notch on the lip of the bobbin case. Pull the thread down and to the left so the thread enters the case under a small metal flap.
Now it's in.
Grab the bobbin lever in the open position and replace it. Bobbin arm facing up and lever closing right to left. Now it should be locked in place.
Grab the top thread firmly but do not pull on it. You're going to lower the needle to grab the bottom thread, and you'll want to keep this thread end from disappearing.
Turn needle wheel counter clockwise (toward you). To move the needle down & back up.
Now if you pull on the top thread it should bring the bottom thread up like this.
Grab the bottom thread and pull it out to match the length of the top thread and move them both from front to back under the foot.
Now you're ready to sew.
