SINGER 12K Family - Manual (Page 3)

at the same time allowing the feet to move freely and lightly with
the motion of the treadle. Continue to do this until a regular and
easy movement is acquired and you are able to work the treadle so
that you can re-start the machine without the balance wheel
turning in the wrong direction.
When familiar with the working movement, lock the balance
wheel, and place a piece of material under the presser foot (23).
Lower the latter by means of the lifter (25) and again work the
machine, without its being threaded, until you are accustomed to
guiding the material.
TO SET THE NEEDLE.
Raise the needle bar (9) to its highest point and loosen the
needle clamj) nut (12). Hold the needle with the left hand and,
with its long groove towards you, place its point down through the
hole in the throat plate (31). Turn the wheel (88) slowly towards
you, while you guide the needle under the needle clamp (11), then
tighten the clamp nut (12). With the left hand insert the point
of a fine needle into the eye, resting it on the throat plate (31).
Loosen the clamp nut or screw (12), and pressing the fine needle
into the eye in a direct line from you, turn the wheel (88) slowly
until the line engraved on the needle bar (9) is level with the toj) of
the arm. Then tighten the clamp nut or screw (12).
TO THREAD THE NEEDLE.
Place a reel of thread on the spool pin nearest the balance wheel
and lead the end of thread through the guide (4), then down from
front to back under and between the tension discs (6), up and from
front to back through the hole in the check lever (15), down and
through the hole in the needle clamp (11), then from front to back
through the eye of the needle, leaving an end of thread three inches
long, which should be i)laced under and to the back of the presser
foot.
TO WIND THE BOBBIN.
Withdraw the left slide and turn the balance wheel until the
shuttle is in full view, then lift it from the machine and remove the
bobbin. Put a reel of thread on the spool pin, place the
bobbin in the spooler (41) and secure the end of the thread by
placing it between the end of the bobbin and the cup of the
spooler. Operate the machine and guide the thread upon the
bobbin slowly from one end to the other, always having the
thread a trifle higher at the ends than in the centre.
