control box and slowly open the rear cover.
A.Incaseofusingwith3-phase200Vto240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover con-
nector of FLT p.c.b. 1located on the side of the
Box Side of the control box.
• Connect the crimp style terminal of AC input cord
tothepowerplugasshowninthegure.
B. Incaseofusingwithsinglephase100Vto120V
• Changing the changeover connector
Connect to 100V the 100/200V changeover
connector of FLT p.c.b. 1located on the side of
the Box Side of the control box.
• Connect the crimp style terminal of AC input cord
tothepowerplugasshowninthegure.
(Caution) Securelyperformtheinsulationtreat-
menttotheredterminalwhichisnot
usedwithinsulationtapeorthelike.
 (Whentheinsulationisinsufcient,
thereisadangerofelectricshockor
leakagecurrent.)
C. Incaseofusingwithsinglephase200Vto240V
• Changing the changeover connector
Connect to 200V the 100/200V changeover con-
nector of FLT p.c.b. 1located on the side of the
Box Side of the control box.
• Connect the crimp style terminal of AC input cord
tothepowerplugasshowninthegure.

6.Installationofbobbincase
1) Lift up and hold bobbin case latch lever between
twongers.
2) Push the bobbin case into the hook so that it is
supported by the hook shaft 1and then snap in
the latch lever.
Press the bobbin case until the predetermined
position is reached, and it will click.
 1. Ifthebobbincaseisoutofthe
predeterminedposition,itcanjump
outfromthehooktocausethe
needlethreadtotangleonthehook
shaft.Checktobesurethatthe
bobbincaseisproperlyinstalledin
thecorrectposition.
 2. Thereisadifferenceintheshapeof
bobbincasebetweenthestandard
hookandthedryone.Theyhave
nothingincommonwitheachother.
Adjust the bobbin thread tension as given below when the bobbin thread is pulled up at the position where
thread slit 1of bobbin case comes up.
Purl stitch
Whip stitch
0.05 to 0.15N
0.15 to 0.3N
To such an extent that bobbin case quietly comes down when
holding thread end coming from bobbin case and shaking it quietly
up and down.
To such an extent that bobbin case barely comes down when
holding thread end coming from bobbin case and shaking it
somewhat strongly.
WARNING:
To protect againstpossible personalinjury dueto abrupt start of themachine, besure tostart the

Turning tension adjust screw 2clockwise will increase bobbin thread tension, and turning it
counterclockwise will decrease the tension.
Adjustthebobbinthreadtensiontolowerforsyntheticlamentthread,andtohigherforspunthread.
The thread tension is higher by approximately 0.05N when the bobbin case is set to the hook since idle-
prevention spring is provided.
 Whenbobbinthreadtensionisadjusted,checktheneedlethreadtensionsettingof
thememoryswitch.(SeeP.44.)
