- Insertion procedure: Switch off the main switch, lower the presser foot and insert the needle with its flat side toward the rear, pushing it fully upward. Hold the needle and tighten fixing screw 18 firmly.
Changing the needle Switch off the main switch To remove: Lower the presser foot and move the needle to its highest point. Now loosen the fi xing screw (18) and pull the needle downwards. To insert: The fl at side A of the needle must face to the rear. Lower the presser foot and insert the needle, pushing it up as far as it goes. Hold the needle and tighten the fi xing screw (18) fi rmly. Setting the needle thread tension Set the required needle thread tension (10) with the help of the mark A. The normal setting for sewing is 4 to 5. For embroidering, darning and buttonhole set the tension between 2 and 3. Dropping the feed dog For certain sewing work, e.g. darning the feed dog has to be dropped. To do this, open the bobbin case/hook cover and move slide A fully to the right. Now the feed dog is dropped.

What this passage proves
- Integrated dual feed: The IDT system feeds material from the top and bottom simultaneously.
- Idt condition: For sewing with the top feed, use only feet with a cutout at the back.
The Intigrated dual feed/IDT System (Models 1530 and 1540) PFAFF offers the ideal solution for sewing diffi cult materials: the intigrated dual feed. This system feeds the material from the top and bottom simultaneously as is done in industrial sewing machines. The fabric is fed precisely. When sewing light or diffi cult materials such as silk and rayon fabrics, the dual feed prevents seam puckering. Engaging the Intigrated Dual feed (Models 1530, 1540) Important! For all sewing jobs with the top feed, only use sewing feet with cutout at the back. Raise the presser foot. Then push the top feed (17) downwards until it snaps into place. Disengaging the Intigrated Dual Feed Hold the dual feed with two fi ngers at the marked places. Push the top feed (17) down a little and out to the rear, and let it move slowly upwards. The even feeding action also ensures perfect matching of checked and striped fabrics.

Inserting the bobbin Insert the full bobbin into the bobbin case. In doing so, pull the thread sideways through slot A, then under the tension plate B until it rests in the opening (see arrow). Check: When you look at the bobbin and pull the thread, the bobbin must turn clockwise. Inserting the bobbin case Lift lever F and slide the bobbin case onto the hook pin D as far as it will go. Opening E of the bobbin case must face upwards. Check: Pull the bobbin thread sharply. The bobbin case must not fall out of the hook.

Removing the presser foot Turn off the main switch Position the needle at its highest point Press the presser foot upwards at the front and downwards at the back at the same time so that it disengages from the presser foot holder (14) Engaging the presser foot Place the presser foot under the presser foot holder (14) so that when the presser foot lifter (19) is lowered, the pins of the foot engage in the presser foot holder. Check: Please check that the presser foot is properly engaged by raising the presser foot lifter.
