Adjustment Procedures

Results of Improper Adjustment

1) Stitch length adjustment

1. When the stitch length adjusting window spring 

 is removed, the

lever setscrew 

 can be seen.

o Loosen the lever setscrew 

 to move the lever upwards and fasten

the lever setscrew 

 there. This action increases the stitch length.

o Loosen the lever setscrew 

 to move the lever downwards and fas-

ten the lever setscrew 

 there. This action decreases the stitch length.

(Caution) No graduation is available for the adjustment of the stitch

length.

2) Adjustment of differential feed amount

1. When the differential adjusting lever 

 is advanced in the reverse

differential direction (1 to 4), the differential ratio is decreased and

the sewed materials are extended.

2. When the differential adjusting lever 

 is retreated in the forward

differential direction (6 to 9), the differential ratio is increased and the

sewed materials are shrunk.

*

When fixing the differential adjusting lever 

, pinch it with two set-

screws 

 and 

.

When the stitch length is changed

o If the forward or backward move-

ment of the main feed dog is

changed, the amount of contact is

also changed in regard to the left

needle and the rear needle holder.

Since this can be a cause of stitch

skipping, the rear needle holder

should be readjusted.
