Instructions for the

Differential Feed

Mechanism (Models with Differential Feed)

This serger is equipped with two sets of feed dogs under the presser foot to move the fabric through the machine. The differential feed controls the move- ment of both the front and the rear feed dogs. When set at 1, the feed dogs are moving at the same speed (ratio of 1). When the differential feed ratio is set at less than 1, the front feed dogs move slower than the rear feed dogs, stretching the fabric as it is sewn. This is effective on lightweight fabric that may pucker. When the differential feed ratio is set at greater than 1, the front feed dogs move faster than the back feed dogs, gathering the fabric as it is sewn. This function assists in removing the rippling when serging stretch fabrics.

∙To adjust the differential feed.

(1)Locate the differential feed adjustment lever on the left side of the machine.

(2)The normal setting is 1.0 on the differential feed adjustment lever.

(3)To set less than 1.0, move the lever back. (4)To set greater than 1.0, move the lever forward.

Instrucciones para el

mecanismo de alimenta- ción con diferencial (Modelos con alimenta- dor diferencial)

Esta máquina de coser está provista de dos series de alimentadores debajo del prensatelas para guiar el tejido por la máquina. El alimentador con diferen- cial controla los movimientos de los alimentadores delanteros y traseros. Al ajustarlo en 1, los alimentadores se desplazarán a una velocidad idén- tica (relación de 1). Al ajustar la relación del alimen- tador con diferencial en menos de 1, los alimentadores delanteros van a moverse más despacio que los traseros, estirando el tejido a medida que se cuese. Esta operación resulta muy eficiente al coser mate- riales finos que pueden arrugarse.

Cuando el alimentador con diferencial esté ajustado en un valor superior a 1, los alimentadores delante- ros van a moverse más rápido que los alimentadores traseros, juntando el tejido al coserlo. Esta función permite quitar las arrugas al coser tejidos que se estiran.

∙Para ajustar el alimentador diferencial. (1)Busque la palanca de ajuste del alimentador

diferencial en al lado izquierdo de la máquina. (2)El ajuste normal es de 1,0 en la palanca de ajuste

del alimentador diferencial.

(3)Para ajustar menos de 1,0, mueva la palanca hacia atrás.

(4)Para ajustar más de 1,0, mueva la palanca hacia adelante.
