NEEDLE
The machine is set up to use Needle Cat. No. 4950 in si/e ranging lioni 18
to 29.
The thickness of tlie sewing thread, which must pass freely through the needle
eye, determines the size of the needle.
To insert the needle, turn the machine pulley toward you, until the needle
bar rise to its highest point, loosen the needle set screw (2) and put the needle
up into the needle bar as far as it will go, with the long groove of the needle,
or toward you. Then, tighten the needle set screw securely.
THREAD
Otdy left twist thread is to he used for
the needle, to test for twist, hold a length
of thread between thumbs and iiulex
fingers of your hands. Turn the thread
counterclockwise.
If it will twist tighter, it has a left .'twist.
If it unravels, it has a right twist.
The bobbin can be wound with either left or right twist thread.
WINDING BOBBINS (Figs. 2 and 15)
The bobbin winder is mounted on the table top with its pulley (5, Fig. 2)
in front of the driving belt so that the pulley will separate from the belt after
the bobbin has been wound with sufficient thread, push the bobbin on the
bobbin spindle (3 Fig. 15) as far as it will go.
Pass the thread from the thread stand downward through the eye (1, Fig. 1,5)
in the tension bracket.
Then, between and around the hack of the tension discs (2 Fig. 1,5) bring
the thread forward toward the bobbin and wind from below in clockwise direc
tion several times around the bobbin. Push bobbin winder lever (4, Fig. 15)
downward until the wheel (5) contacts the drive belt and start the machine.
After the bobbin is filled with thread, release will cause the wheel to disen
gage from the belt and winding will stop. Cut the thread and remove the
bobbin from the winder spindle.
The adjusting screw (A, Fig. 15) can be turned in or out to increase or
decrease the amount of the thread wound on the bobbin.
If the thread does not wind evenly on bobbins, loosen the screw (B, l ig 1.5)
and move the bracket to the right or left as may be required and tighten the screw.

See the instructions for SK machines.
ADJUSTING THE PRESSER FOOT PRESSURE (Fig, 7)
The pressure of the presser foot is regulated by the screw (1).
To incrca.se the pressure, turn it to the right and to the left to decrease the pressure.
GAUGE PARTS
There are three kinds of gauge parts (needle clarttps) as 3.5 mm 4.8 mm and
7.5 mm, wliich can be changed according to your purpose, replace it to the re-
(luired size.
ONE OR THREE NEEDLE MACHINE (SKM only)
One needle machine is used for decorative coarse straight stitching.
On three needle machine, either the right or left side (two needles) make
moccasin stitch and the other needle makes decorative coarse stitching.
I hree needle machine can also be used for only the decorative coarse stitciiing
I hese stitchings can be made by replacing the re.spective presser foot, needle
clamp, needle plate, and feeder.

needle bar raises to .'1.8 iiiiii from its lowest position.
Bring the hook point (I, I'ig. .’!(i) to the renter between two needles (2) and
(.'!), then tighten the hook screws, at the same time, set the clearance between
the needle and hook point 0.1mm to 0.2 mm.
ASSEMBLING THE HOOK RETAINER BRACKET
This must be done after adjusting
the clearance between the needle and
hook.
Let the retaining spring (2) contact
sufliciently, but not to bend, with the
hook (3) without any clearance, then
tighten the screw (4) securely.
Excess contact between the two
makes unnecessary wear and noise.

the feed dog to its highest position.
Loosen tite screws (I,
Fig. 41), adjust the height
of the feeder by raising or
lowering it to 1.4 mm
from the surface of the
needle plate to the feeder.
Tlicn tighten the said
screws securely.
Fig. 38
ADIUSTING THE HEIGHT OF THE NEEDLE BAR
This shotdd be made after the timing between the
needle and hook has been determined.
Turn the balance wheel toward you so as to fit
the center of the left needle to the hook point.
Loosen the screws (1, Fig. flH), adjust the needle
bar up or down so that the up|ier end of the needle
eye comes to 3.5 mm down from the book point,
at the same time, the two needles must be parallel.

TIMING BETWEEN NEEDLE AND FEEDER
The correct timing is as follows:
Adjust the feeding motion to the maximum and turn the balance wheel to
ward you, after the feed dog has finished its feeding motion and when teeth
of the feeder become equal height to the surface of the needle plate, the needle
reaches to the needle plate.
To adjust this, pull open the top cover (I), loosen three screws (3) out of
five on the feed eccentric adjusting flange coupling (2) and move the feed ec
centric adjusting flange (4) for the adjustment.
Fig. 43 Fig. 44
ADJUSTING THE UP AND DOWN TRAVEL OF THE FEEDER
The adjustment of the up and down travel of the feeder against its hack and
forth travel is made so that the teeth of the feeder rise to the highest point
at the middle position, when feeding travel is the largest.
Loosen two screws (5) and adjust it against the main shaft by moving the
feed lifting cam (6).
To make its up and down travel faster, turn the feed lifting cam toward
driving direction and to make it slower, turn the cam toward opposite direction.
Be sure to tighten screw pushing the screw against the rod (7) not to make
any clearance axialy.
ADJUSTING THE HEIGHT OF THE PRESSER FOOT
