Singer 144W204 - Thread, Needle, and Component Handling; Thread Twist Determination; Setting the Needle; Removing Bobbin and Bobbin Case

THREAD
Use left twist thread for the needle. Either left or right twist thread
may be used for the bobbin.
Fig. 6. How to Determine the Twist
Hold the thread as shown above. Turn the thread over toward you
between the thumb and forefinger of the right hand; if left twist, the strands
will wind tighter; if right twist, the strands will unwind.
TO SET THE NEEDLE
Turn the machine pulley over toward you until the needle bar moves
up to its highest point; loosen the set screw in the needle bar and put the
needle up into the bar as far as it will go, with its long groove toward the
left, the eye of the needle being directly in line with the machine bed, then
tighten the set screw.
TO REMOVE THE BOBBIN
Draw back the slide plate in the bed of the machine and turn the
rnuchine pulley until the bobbin case opener (M, Fig. 7) moves clear of the
bobbin. Wrth the forefinger or a screwdriver, raise the latch (l) to a ver-
tical position and lift out the bobbin.

Usually when the feed dog is at its highest position, it should show a
full
tooth above the throat plate.
Remove the throat plate; clean the lint and dust from between the
feed points and replace the throat plate; tip the machine back and turn
the machine pulley towards you until the feed dog is at its highest position;
loosen screw (U, fig. 20) in the feed lilting cam fork on the feed bar and raise
or lower the feed dog, as may be required, and retighten the screw (U).
When raising or lowering the feed dog, be careful that its underside
does not drop low enough to strike the sewing hook.
