When stitching the curtain fabric, if the stitching is not firm, please release the lock nut and rotate the pressure-adjusting bolt to the right to increase the pressure. After adjusting the stitching pressure, tighten the lock nut. If the stitching pressure is too large, rotate the pressure regulating nut to the left to reduce the sewing pressure. After the sewing pressure is adjusted properly, tighten the lock nut.
By rotating the set screw, adjust the gap between the threaded roller and the stitching gear installed at the front end of the indenter. The initial clearance of the factory is about 0.5mm, and the adjustment should not be less than 0.3mm. When the curtain fabric has great thickness, properly adjust the gap and then tighten the butterfly nut to prevent the set screw from loosening
