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 movement

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.

差动送料装置说明

（带差动送料的型号）

这种锁边器在压脚下具有两套送布牙来让缝纫机移

动布料。差动送料可控制前后送布牙的移动。设

置为 1 时，送布牙以相同的速度移动（比例为 1）

。差动送料比例设置小于 1 时，前部送布牙比后部

送布牙移动速度慢，在缝制时会将布料伸展。这对

于容易褶皱的轻质布料有效。差动送料比例设置大

于 1 时，前部送布牙比后部送布牙移动速度快，在

缝制时会使布料收缩。该功能可在伸缩布料锁边时

去除褶皱。

• 调整差动送料。

(1) 请找到机身左侧的差动送料调整杆。

(2) 差动送料调整杆的正常设置为 1.0。

(3) 若要设置为小于 1.0，则向后移动调整杆。

(4) 若要设置为大于 1.0，则向前移动调整杆。
