Slide sliding board 2 back into place after this adjustment is made. 1 2 3 4 5

Always turn off the power, unplug the machine and then well-qualified technicians should adjust the fabric edge. 1. Loosen screws 1. 2. To make a standard adjustment, move table board 3 as required in the direction of arrow A and then align end 2 of the guide with the center of the slot on the needle plate (see the illustration). 3. If the fabric edge protrudes from the seams produced by the left needle, move the end of the guide slightly in the direction of arrow B. If the fabric edge retracts into the seams produced by the left needle, move the end of the guide slightly in the direction of arrow C. The following adjustments should be made if the fabric edge protrudes from or retracts into the seams produced by the left needle. The fabric edge protrudes from the seams. The fabric edge retracts into the seams. 2 B C A 1 3 CCAAUUTTIIO ONN

Always turn off the power, unplug the machine and then well-qualified technicians should adjust the binder. Adjust the binder if it is difficult to position the fabric under the binder or the hem is not uniformly formed. 1. Loosen screws 1. 2. Move binder 2 in the direction of arrow A. Adjust clearance B between middle plate 3 and binder 2 according to the fabric (3mm is standard). ●If B is too small for the fabric, it is difficult to position the fabric under the binder. ●If B is too large for the fabric, the hem is not uniformly formed. 3. Tighten screws 1 after this adjustment is made. 1 2 3 B A CCAAUUTTIIO ONN

Always turn off the power, shut down the air compressor first and well-qualified technicians should adjust hem width. To adjust the hem width 1. Loosen screws 1 and 4. 2. Slide sliding board 5 in the direction of arrow A. Adjust the hem width while referring to the scale at the front or back end of sliding board 5. Tighten screws 4 after this adjustment is made. 3. Align the end of fabric guide 2 with that of binder 3. Tighten screws 1. ※ The scale should be used as the reference. To form the hem properly, check the finished hem and then make a fine adjustment. 2 1 3 CCAAUUTTIIO ONN 4 5 Scale (front) Scale (rear) A

3 Air blow 1･･･････To position the fabric along guide 8. If the air blow is too strong, jamming of the fabric tends to occur. If the air blow is too weak, the hem is not uniformly formed. Adjustment is made by turning knob 4. Air blow 2･･･････To position the fabric correctly under the binder. If the air blow is too strong or too weak, the fabric is not positioned properly under the binder. Adjustment is made by turning knob 5. Air blow 3 ････････････････････････････To remove the fabric when sewing is completed. Adjustment is made by turning knob 6. ※ To adjust each air blow, loosen nuts 7 first and then turn each knob. To increase the amount of air blow, turn each knob counterclockwise. To decrease the amount of air blow, turn each knob clockwise. Tighten nuts 7 after the adjustment is made. 4 5 6 7 2 1 8
