NOTE:

The bobbin thread tension has already been adjusted at the fac- tory for general use. For most sewing applications, no adjustment is needed.

When sewing with thin thread on thin fabrics, the thread tension may not be adjusted adequately with the upper tension control dial. Therefore, the thread tension must be adjusted according to the procedure described below.

CBobbin tension is too loose.

Locks appear on the surface of the fabric.

Decrease the thread tension by turning the dial to a lower number. If the result is still not satisfactory, then adjust the bobbin thread tension as explained in C-1

C-1 Bobbin

Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.

Remember to return the screw to its original setting before starting your next project.

D Correct tension

Correct tension is important since too much or too little ten- sion will weaken your seams or cause puckers in your fabric.

NOTA:

La tensión del hilo inferior ya se ha ajustado en fábrica para los usos comunes. Por lo tanto, para la mayoría de las costuras, no se requerirá ningún ajuste adicional.

Sin embargo, al coser con hilo delgado en tejidos finos, no se puede ajustar correctamente la tensión del hilo mediante el disco de control de la tensión superior. En esos casos, la tensión del hilo ha de ser ajustada de acuerdo con el proceso descrito a continuación.

C.La tensión del hilo inferior es insuficiente.

Aparecen bagas en la superficie del tejido.

Disminuya la tensión del hilo al girar el disco hacia un número inferior. Si el resultado no le conviene aún, ajuste la tensión del hilo de la canilla tal como se indica en C-1.

C-1 Canilla

Aumente la tensión en la canilla girando el tornillo, con un pe- queño destornillador, en el sentido de las manecillas de un reloj. Sin embargo, no conviene dar más de una vuelta completa al tor- nillo.

No olvide volver a colocar el tornillo en su posición original an- tes de empezar otro tipo de costura.

D.Tensión correcta

Es importante tener una tensión correcta dado que una tensión insuficiente o demasiada tirante va a debilitar sus costuras o fruncir el tejido.

REMARQUE:

La tension du fil inférieur a déjà été réglée d’usine pour une utili- sation normale. Pour la plupart des applications de couture, il ne sera dès lors pas nécessaire de la régler.

Cependant, lors de la couture avec du fil fin sur des tissus légers, les réglages de tension du fil effectués à l’aide du disque de con- trôle de la tension supérieure sont insuffisants. Dans ce cas, régler la tension du fil selon la méthode décrite ci-dessous.

CLa tension inférieure est insuffisante.

Formation de boucles à l’endroit du tissu.

Diminuer la tension du fil en mettant le disque sur un chiffre inférieur. Si le résultat n’est pas encore concluant, régler la tension du fil de la canette comme expliqué au point C-1.

C-1 Canette

A l’aide d’un petit tournevis, augmenter la tension de la ca- nette en tournant la vis dans le sens des aiguilles d’une mon- tre, sans effectuer plus d’un tour complet.

Ne pas oublier de remettre la vis à sa position originale avant d’entamer un nouvel ouvrage.

DTension correcte

Il est essentiel de procéder à un réglage correct de la tension du fil pour avoir des coutures solides sans que le tissu ne fronce.

NOTA:

A tensão da linha inferior vem regulada de fábrica para trabalhos nor- mais de costura. Para a maioria das aplicações, não é necessário qual- quer ajuste.

Quando costurar tecidos finos com linha fina, a tensão da linha não pode ser adequadamente regulada apenas com o disco de regulagem da tensão da linha superior. É necessário regular a tensão da linha segundo o processo abaixo descrito.

CA linha inferior está muito frouxa.

Aparecem pontos com laçadas na parte superior (direito) do teci- do.

Diminua a tensão da linha girando o disco de regulagem da tensão da linha superior para um número inferior. Se o resultado ainda não for satisfatório, ajuste então a tensão da linha da bobina, da forma abaixo explanado em C-1.

C-1 Bobina

Aumente a tensão da linha na bobina girando o parafuso com uma pequena chave-de-fendas, para a direita. Todavia, não gire o para- fuso mais de uma volta completa.

Não se esqueça de repor este parafuso na sua posição inicial antes do seu próximo trabalho.

D Tensão correcta

Éimportante que a tensão esteja correcta porque se for excessiva ou insuficiente enfraquecerá as costuras ou provocará a ocorrên- cia de franzidos no tecido.
