CHAPTER1:INSTALLATION
FLY WHEELROTATION
While sitting infrontofthe machine and you putyour handon the top ofthe Fly
Wheel you havetopushthe flying wheel awayfromyou (backwards).
The FlyWheelmustturn clockwise.NEVERPULL !!
TRAINING
Tousethe CornelyLG3 isnotthatdifficult,the only thing you havetodo is
practising.
You havetobegin tosewonthe pieceofpaper on whichthe design isdrawn.
You havetofollowthisdesign by operating the crank.
The socalled hook(=needle) will punchalong thispre-traceddesign together with
the movementsoftheCrankC.00797 (Fig.1B).
After awhile you can handle itperfectly.
TOSTARTSEWING
You havetostartthe motor bypressing the pedal and the motor startsrunning.
The harderyou pushthe faster the motor will run.
Tostop the motor you havetoreleasethe pedal sothe speed willdecrease.

CHAPTER 2:MECHANICALADJUSTMENT
1.NEEDLESETTING
Selectcarefullythe needle according thethicknessofthe thread.
Screwtightlythe needle intothe needle holder C.01120 bymeansofthe flat
tweezer delivered withthe accessories.The needle should be positioned in theflat
opening ofthe needle holder.(Fig.A)
C.01120

The needle holder ispassing through the tube C.10273 and should beplaced in
the correctposition withthe screwC.10298 byhand andadjustthe heightsothat
the material can slide under the needlewithouttouching it.(Fig.B)

The crankC.00797 and the hookand the cone lever C.10033 mustbe placed in
the samedirection.(Fig.1A-1B)
Thismeansfor the Chain-stitch at6o’clock.

3.NEEDLEPLATESETTING
The needleshould pass theneedle platein one ofthe 12 foreseen holes.
Usethe hole justinfrontfromwhere the threaded needle iscoming outofthe
needle plate.
Chooseaconvenienthole sothatthe needle can passfreelythough the hole.The
needle must be exactlyin the middle ofthe hole.
Don’tusetoo large holes,especiallywiththin material.
Ifthisisnotthe case,do the following :
Toturn the plate:C.01707 (Fig.3),unscrewpartC.00056 (Fig.2) and usethe
curved pointknife.
Ifthe hole iscorrectlyplaced,screwpartC.00056 again.(Fig.2)

terylene,cellophane,plastics,metal threadsetc.
Workwithachain stitchand checkthatthe hookpointof the needle isin the same
placeasthe flatedge ofneedle tube.Then setthe braiding attachmentC.10288W

Placethe braid,cord or ribbon,etc.onthe spool L(Fig.9) abovethe head ofthe
machine. Usesmall ballchaplet topassthe braid through the needle tube,
entering top opening,going outof the needletube through the botton opening,then
passing through the suitable guideor nipple. (See Chapter 7.)
Nipple mustbe in the samedirection asthe hollowpartofthe needle tube
The nipple iscomposed offour parts :
-small tube tightened in the needle tube
-screw.
-Small spring for clothpressure (iftaping)
-guide
The braidmustslide freelyin thenipple butreasonable.When youaskfor anew

SEVERAL THREAD WORKS
Accessoriesare mounted onweavinggear C.10294 and are marked A&C,as
well ason the gear.(Fig.11)
Twothreadsworks are madebybraid curling around the chainstitchrowwhich
sewsiton the cloth.
Three threadsworksaremade withadditional stuffing between coiling and chain
stitch.
a.Twothreadsworks
Usethe following parts:
-Spoolholder C.10632Wmountedon the weaving gear C.10294
-Weaver C.10300W
-Nipple C.00601C...for 2threadsscrewed in lower tube (according
thickness)
(Fig.11).
The thread comesfromspool C.00635M, passesthrough the hole ofthe weaver
holder C.10302 through the eyeletC.00619 then intothe thread guide C.10304/1.7
or C.10304/3,according tothe thickness.
Letthe lacepass under the pressure foot. The thread tension isadjusted bythe
screwwhichisunder the spoolholder.
The weaverheightsettingswill be made when the machine isdisclutched andthe
nipple isin upperposition.Releasethe weaver assemblyholding screwandset
the lining withlower partofnipple.
Sincein twothreadsworks,the chain stitchiscompletelycoated bythe coiling
thread,machine mustbe setwitharather shortstitch.
b.Three threadsworks

-Spoolholder C.10632Wcomplete
-Weaver C.10300Wcomplete
-Nipple C.01127A… for three threads, sizeaccording tocord

Sameworksaswithtwothreads, plusa“Stuffing” thread whichmustcomethrough
the hookneedle holder.Itisbetter tousearather flexible material.
Putthe cranktowardsthe operator,the stuffing thread passage hole mustbe on
the oppositeside.The hookneedle will be screwed sothatitshookwill be on the
oppositeside ofthe flat part ofthe needleholder.The coiling thread comesfrom
spool C.00635Mand passesthrough holes.Followthe instructionsasfor 2
threads.The stuffing thread comesfromthe braiding attachmentC.10288W

working on circles orcurves.
WARNING:
For all thosekindsofworks,makesure thatthe weaving gear iscorrectlyset.
Tocheckthis,run the machineatfull speed tobe surethedeclutching iscorrect.

CHAPTER 5:ADJUSTINGTHETHREADTENSION
The thread tension can beregulated by 1.adjusting the needle height
2. adjusting the thread tension
a.Adjusting the needle height
Ifyou wantaverythin stitchyou havetolower theneedle.
Ifyou wantavery large stitchyou havetoupper the needle butnotTOO high
becausethiscan causelackofstitches.
b.Adjusting the thread tension
There isalsohereadifferencein adjusting the thread tension depending fromthe
Cylindrical orConical spoolholder.
The tensioncannotbe too high or too less.
For the cylindrical spoolholder you can regulatethe tension bythe lever C.00094
(Fig.6)
