TO KEEP YCIUR SEWING MACHINE RUNNING WELL, WITH IT 3U !N THE RIGHT WAY, AKE USING THE MACHINE, IT WILL
YOU MUST WORK
IF YOU FOLLOW THESE STEPS WHEN NOT GO WRONG SO EASILY, ON HOW TO USE
NOTE :
THESE ARE NOT COMPLETE INSTRUCTIONS THE MACHINE,
BUT STEPS TO TAKE CARE WITH,
THREAD MACHINE THE1, TURN THE WHEEL TOWARDS YOU TO RAISE THE TAKE-UP LEVER AS HIGH AS IT WILL GO,
2,
PUT A SPOOL OF SEWING COTTON ON THE SPOOL PIN,
3,
THREAD THE MACHINE LIKE
THIS:
SOME
MACHINES
OTHER
MACHINES

4,
MAKE SURE THE COTTON GOES AROUND THE TENSION SOME MACHINES REGULATOR LIKE THIS:MACHINES OTHER MACHINES
OTHER
TAKEOUTTHE BOBBINCASE1, SLOWLY TURN THE WHEEL TOWARDS YOU UNTIL THE NEEDLE GO, IS AS HIGH AS IT WILL
2,
OPEN THE COVER PLATE,
3,
USE TWO FINGERS
TO PULL
THE LATCH OF THE BOBBIN CASE n PULL THE BOBBIN CASE OUT OF THE MACHINE, WHEN YOU LET GO OF THE LATCH, THE BOBBIN WILL DROP OUT,
THREAD BOBBINCASE THE1, MAKE SURE THERE IS ENOUGH COTTON ON THE BOBBIN,
2,
HOLD THE BOBBIN CASE IN ONE HAND, USE YOUR OTHER HAND TO PUT THE
BOBBIN INTO IT, PUT Tb!!E BOBBIN IN WITH THELOOSE END OF CGTTON HANG1 NG DOWN IN FRONT (FACING YOU>,
3,
PULL THE THREAD INTO THE SLOT IN THE EDGE OF THE BOBBIN CASE,-SLOT
4,
PULL THE THREAD UNDER THE TENSION SPRING AND ENSION SPRING
I NT0 THE SMALL HOLE ON THE SIDE OF THE BOBBINCASE,
5,
PULL THE LATCH,
AND KEEP IT OPEN NOT FALL OUT,
SO THE BOBBIN WILL
PUT BACKTHE BOBBINCASE1 n HOLD THE BOBBIN CASE BY THE LATCH a PUT IT
IN PLACE,
HOLDING
IT UP THIS WAY:
2,
LET GO OF THE LATCH, THE BOBBIN CASE IN, HEAR A SMALL CLICK, STAY IN PLACE,
AND PRESS UNTIL YOU THIS
MEANS THE BOBBIN CASE WILL
PUT IN THE NEEDLE1, SLOWLY TURN THE WHEEL TOWARDS YOU UNTIL THE NEEDLE BAR IS AS HIGH GO, AS IT WILL
2,
LOOSEN THE NEEDLE CLAM? SCREW,
3,
HOLD THE NEEDLE WITH THE THICK TURN IT SO THE FLAT SIDE TO THE RIGHT, NOTE : ON A FEW MACHINES, SIDE TO THE BACK,
END
IS FACING
THE FLAT
OF THE NEEDLE MUST FACE SEE PAGE 61,
4,
PUT THE NEEDLE INTO THE HOLE AT THE BOTTOM OF THE NEEDLE* BAR m PUT IT IN AS FAR AS IT WILL GO,
5,
TIGHTEN
THE NEEDLE CLAMP SCREW,
CHANGE THREAD THE TENSIONS1, THE TENSION TENSION OF THE UPPER THREAD
SHOULD BE THE SAME AS THE OF THE LOWER THREAD,
RIGHT
BOTH THREADS SHOULD FASTEN TOGETHER
IN THE CENTRE OF THE SEWN CLOTH,LOWER THREAD

WHEN BOTH TENSIONS
ARE RIGHT,
THE STITCHES ON BOTH SIDES OFTHE SEWN CLOTH ARE THE SAME
SIZE,

TO GET THE RIGHT
TENSIONS,
YOU MUST:
I> BE SURE THE PRESSER FOOT IS DOWN WHEN YOU SEW II> USE THE SAME COTTON FOR BOTH THE UPPER THREAD AND THE LOWER THREAD,------------m_
NOTE :
THE THICKNESS
OF THE CLOTH YOU ARE SEWING MAY YOU WILL THEN NEED TO AS SHOWN BELOW,

TO KEEP YOUR MACHINE RUNNING WELL, BEFORE YOU START SEW1NG AGAIN o BE ESPECIALLY
CLEAN IT AND OIL AND OIL

OIL
THE MACHINE AT ALL THE PLACES SHOWN BY ARROWS,
OR AT ALL THE SMALL HOLES,
USE SEWING MACHINE OIL, DO NOT USE ANY OTHER KIND OF OIL,
PUT ONLY ONE OR ThO DROPS OF 01 L AT EACH HOLE, TOO MUCH OIL WILL GET ON THE SEWING,
2,
WHEN YOU HAVE PUT OIL ALL THE HOLES, THE NEEDLE, FEW MINUTES WILL PLACES IT
