CHANGING THE NEEDLE
Flat side
Always make sure needle is straight.
To check straightness of needle, lay needle on a flat surface and see
that needle is straight and parallel as shown m above diagram.
Turn hand wheel toward you to raise needle bar to its highest posi-
Loosen needle clamp screw and insert needle upward as far as it will
go, making sure flat side of needle is towards back of machine as
shown in the above diagram.
Tighten needle clamp screw with screwdriver.
Follow the same procedure for insertion of twin needle.
To make sure that needle has been inserted
wheel toward you and see that needle comes down through the
center of the needle hole in the needle plate as shown in the above
Stiteh selector dial must be set in straight stitch needle position
when checking needle alignment.
If skipped stitches occur, needle may be incorrectly inserted.
WINDING THE BOBBIN
TO DISENGAGE THE HAND WHEEL:
• Hold the hand wheel (1) with left hand, turn clutch (2)
counterclockwise with right hand to disengage as shown.
TO WIND THREAD ONTO BOBBIN:
* Lead thread through spring thread guide (4) and through the hole in
your bobbin from the inside out.
* Place the bobbin onto the bobbin winder shaft (3).
* Push the bobbin winder to the right.
Hold loose end of thread firmly and turn hand wheel to make thread

TWIN NEEDLE UPPER THREADING
• Follow threading instruction for single needle with these exception,
• Place thread, matching or contrasting in color, on both spool pins.
• Draw threads through thread guides as normal, but separate the
threads at the tension.
• Pass on thread through the left disc and one thread through the right
disc.
• Now treat both threads as one until you reach the needle eyes.
ZIGZAG DIAL: Set at desired width between "0" and "3," if you set
dial higher than 3, the needle will hit the needle plate and break.
STITCH LENGTH: Set at desired stitch length.
adjusting feed dog HEIGHT
Upper position of feed dog is used for normal sewing. To raise feed
dog.
Press drop feed button "Jk4k." located under shuttle cover to upper
position.
Lower position is used for Embroidering, Mending or Sewing on
Button. Press drop feed button "UT" to lower position.
PICKING-UP LOWER BOBBIN THREAD
Raise presser foot.
Holding upper thread, turn
hand wheel toward you
one rotation.
When take-up lever is at its
highest position, pull thread
to pick up loop of lower
bobbin thread.
Pull both upper and lower thread
"to the left of" presser foot ap
proximately 6 inches.
This will prevent jamming.
REGULATING PRESSURE
The amount of pressure that is applied to the fabric by the presser
foot is adjusted by the pressure cap (1). The upper position gives the
least amount of pressure while the lowest position gives maximum
pressure. ,
To increase the pressure, push down on the pressure cap to obtain
the desired setting. To decrease the pressure, press down on the
snap lock ring (2) to allow the pressure cap to return to its maximum
height. Then reset to the proper pressure.
Normally the pressure cap will be in the lowest position. If the top
layer of fabric tends to push out further than the bottom layer of
fabric, Pressure should be decreased. This often happens on bulky
fabrics, such as wools, and on knits.
