1 Adjusting the men's mode
S=0 mm
8
1) When turning ON the power switch under the men's sewing mode, carriage 8 should retrieve the origin
and stop at the position as shown in the figure.
To adjust dimension A to 122 ±1.5 mm (4.803" ± 0.059"),loosen the screw in origin detecting plate 4
and move the plate in the direction of the arrow until the specified dimension is provided. (If origin
detecting plate 4 is moved to the right, dimension A will be larger than 122 mm (4.803"). If the plate is
moved to the left ,dimension A will be smaller than 122 mm (4.803"). When dimension A is properly
adjusted, dimension B will be 3 ± 1 mm (0.118" ± 0.039") and dimension C will be 6 mm (0.236").)
2) To check the result of the aforementioned adjustment, turn OFF the power to the machine once, move
carriage 8 by hand to the left by 20 to 30 mm (0.787" to 1.181"), loosen the knob of slide bearing 6 and
set dimension S to 4 mm (0.157").
Now, turn ON the power to the machine, and the error message "CLAMP POSITION ERROR" will be
shown on the display after the machine stars retrieving the origin.
If the sewing machine fails to stop while indicating the above-stated error message, move presser
switch !3 to the left and re-turn ON the power to the machine. If the sewing machine, this time, stops
while indicating the error message, adjust the position of stopper !5 .
3) Turn OFF the power to the machine and set dimension S to 2 mm (0.079").As long as no error is
indicated in this state, the sewing machine is correctly adjusted under the men's wear sewing mode.
After the completion of checking procedure steps 2) and 3), be sure to move slide bearing 6 to the left
and set dimension S to 0 mm. Now, fix the slide bearing.
This completes the adjustment of the origin, presser switch and stopper under the men's wear sewing
mode.
