Make sure your hand is not underneath the presser foot when it is lowered by the pedal or lever. The presser foot can be manually raised when setting up the machine or to remove the material from under the presser foot in an emergency if the compressed air supply has been disconnected from the machine. Fig.
Operation Lowering presser foot: The presser foot can be lowered in two ways: 1. Manually turn hand lever to position(0). 2. Raise presser foot with pedal. Presser foot rises slightly, the hand lever lock disengages and the internal spring moves the hand lever back to position (0). 5.11 Setting presser foot pressure The adjusting wheel at the top left of the machine arm determines the contact pressure of the sewing foot on the material to be sewn.
Operation Fig. 24: Setting presser foot pressure ③ ① H ② (1) - Adjusting screw (2) - Counternut (3) - Auxiliary spring To increase presser foot pressure: 1. Release the counternut (2). 2. Turn adjusting wheel (1) to the right until the desired pressure is reached. 3. If the pressure is insufficient even when the adjusting wheel is fully tightened, use the auxiliary spring (3) provided in the machine accessories. 4. Completely unscrew adjusting wheel (1). WARNING Risk to injury to eyes.
Operation ATTENTION The auxiliary spring greatly increases pressure depending on material thickness. This can cause defects when sewing soft material or sewing over thicker areas in the material. If an auxiliary spring is not absolutely necessary due to the presser foot rising when the needle moves up, do not use one. 5. Insert auxiliary spring (3). 6. Screw in adjusting screw (1) and adjust the presser foot pressure. 7. Tighten the counternut (2).
Operation 5.12 Setting presser foot stroke The presser foot stroke has twelve levels of 1 mm each. Correct presser foot stroke setting Set the presser foot stroke as low as possible, but enough so that the material can pass through evenly with a consistent stitch length. In general, the thicker the material and the greater the changes in thickness over the course of the seam, the higher the pressure foot stroke should be.
Operation 5.12.2 Limiting presser foot stroke When the pressure foot contacts the material, dynamic force is generated that increases with thinner and harder materials. This force puts great strain on the machine and manifests itself through noise. The operator can adjust the pressure foot stroke to suit the material thickness according to the table, Table: Maximum presser foot stroke, page 110.
Operation Fig. 25: Presser foot stroke adjusting wheels ① ② (1) -Adjusting wheel for the normal sewing foot stroke (2) -Adjusting wheel for the increased sewing foot stroke To increase presser foot stroke: 1.
