When the treadle is not depressed [A], the work clamp is at the neutral position. (Figure 1) * The work clamp lifter height at the neutral position can be changed to between 1 mm and 13 mm using memory switch No. 05. (Initial value is 10 mm.) 2. When the treadle is depressed to the 1st step [B], the work clamp lowers, and when the treadle is returned to [A], the work clamp returns to the neutral position. * When memory switch No. 06 is set to off, the work clamp is lowered to its lowest position. (Figure 2) If memory switch No. 06. is set to between 0.1 - 8.0 mm, the work clamp is lowered to the height which has been set. This is useful for positioning the material. (Light work clamp) (Figure 3) 3. When the treadle is depressed to the 2nd step [C], the machine starts sewing. (Figure 4) 4. When the treadle is depressed backward to the position in [D], the work clamp rises to the height which has been set using memory switch No. 04. This is useful for inserting and removing the material. (Figure 5) * The work clamp rises while the treadle is being depressed backward, and it returns to the neutral position when the treadle is released. HE-800A 30
