How to thread a sewing machine – Singer 7258.
THREADING THE TOP THREAD
A. Raise the presser foot lifter. Always be sure to raise the presser foot lifter before threading the top thread. (If the presser foot lifter is not raised, correct thread tension cannot be obtained.)
B. Turn the hand wheel toward you until the needle is in its highest position.
C. Thread the machine with your left hand while firmly gripping the thread with your right hand in the following order as illustrated.
* Guide the thread through thread guide (1 ), and then pull it into the pre-tension guide (2).
* Pull the thread into the tension discs (which are located inside the machine) by first passing the thread to the left of plate (2). Then guide the thread to the bottom of the groove.
* Do a U-turn around the inside of the tab (3).
* Pass the thread through the thread take-up ( 4) from right to left.
* Pull the thread into the inside of the take-up lever until it reaches the eye of the lever.
* Guide the thread into the thread guide (5).
* Pass the thread through the eye of the needle (6) from front to back. (See following page for instructions on operation of the Automatic Needle Threader.)
IMPORTANT:
To verify that the machine is threaded properly in the tension discs, do this simple check:
1.) With the presser foot raised and the needle unthreaded, pull the thread. You should detect only a slight resistance and little or no deflection of the needle.
2.) Now lower the presser foot and again pull the thread towards the the back of the machine. This time you should detect a considerable amount of resistance and much more deflection of the needle. If you do not detect the resistance, this means you have not threaded the machine correctly and need to rethread it. .
