Summarize the following:
Locate the power switch on the side of your sewing machine, and switch it to the off position. Do this before you try to thread your sewing machine. You will be inserting the thread through moving parts of the sewing machine. If the machine remains on and you accidentally apply pressure while trying to thread the machine, you could seriously injure your fingers. Since the power is switched off, you will need to adjust the moving parts manually. Turn the wheel on the right side of your sewing machine in clockwise to move the needle upwards. Stop turning when the needle is at its highest point. If you keep turning the wheel, the needle will move back down again, so make sure to stop turning when it reaches its highest point. Locate the lever next to the needle base on your machine. Push this lever upwards to raise the presser foot. Having the presser foot in this position will make it easier to thread the machine because it will be out of the way.

Summary:
Turn off the sewing machine. Raise the needle using the hand wheel on the side of the machine. Lift the presser foot with the lever.
