A). This eccentric pin adjusts the position of the Walking Foot front to rear. This enables you to align the Walking Foot teeth with the lower feed dog teeth.

B). This screw adjusts the Walking Foot movement in relation to the presser foot. The higher the bracket, the faster the presser foot will meet the needle plate, causing the Walking Foot to raise off the work faster. Lowering the bracket will cause the Walking Foot to raise off the work more slowly.

C). This eccentric pin primarily adjusts the position of the presser foot front to rear.

D). This shaft adjusts the position of the presser foot front to rear. It is used to adjust the clearance between the presser foot and the Walking Foot.

E). This screw holds shaft 'D'. Loosen it to free the shaft.

Any one of the above adjust- ments will slightly change one or more of the other adjustments. Take this into consideration when making any one adjustment. Before running the machine, turn it over by hand to check all clearances.;
