10. STANDARD ADJUSTMENTS 10-16. Adjustment of air pressure (for pneumatic) Increase pressure Increase pressure 2621Q 1. Air pressure should be 0.5 Mpa. The air pressure can be adjusted by pulling up and turning the control knob (2) on the integrator (1). After adjustment is complete, push the control knob (2) downward to lock it. 2. Adjust the air pressure for the reversal cylinder to stay within such a range that the presser crank (4) rotates reversely when pressing the sewing material with the pressure plate (3). (Approx. 0.3 Mpa) For adjustment, pull up and, turn the control knob (6) on the air regulator (5). After adjustment is complete, push the control knob (6) downward to lock it. 3. If water stands in the bottle of the integrator (1), turn the drain cock (7) in the direction indicated by an arrow to drain the water. 2622Q 10-17. Adjustment of inner clamping device Adjustment of the positioning plates Loosen the screws (2), and adjust the position of the positioning plate R (3) so that the label (1) can be evenly laid out between the front and back seams (A). Next, loosen the screws (4), and adjust the position of the positioning plate L (5) so that the presser plate can be evenly laid out between the left and right seams (B). 2623Q Adjustment of the presser crank horizontal position Loosen the nut (3) and push in or pull out the adjusting bolt (4) so that the presser crank (2) can be horizontal when the reversal cylinder piston rod (1) is moved to the left extreme. 2624Q 48 KE-434C,435C
