Threading The Top Thread - Singer 83933 Manual De Instrucciones

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 counter clockwise 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 guides (1 & 2), and then
pull it down along the groove (3).
* Guide the thread into the thread guide (4).
* Pass the thread through the eye of the needle (5) 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, pull the thread towards
the back of the machine. 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 you have mis-threaded the
machine and need to re-thread it.
