Presser foot lowers. 4. When a seam is complete, press the pedal to position (-2). The machine cuts the thread and the presser foot rises. 5.
Operation 6. Press the pedal to position (-2). Thread is cut and presser foot rises. 7. Release the pedal to position (0). Presser foot remains raised until another seam is started. Operating mode: presser foot rises automatically every time the machine stops. 1. Press both keys on the OP1000 control panel (4) for presser foot position. Their signal diodes turn on – see Operating manual for eco/classic DAC control panel. Presser foot rises. 2. Press the pedal (3) to position (+1).
Operation 5.10 Raising presser foot with hand lever CAUTION Risk of crushing when lowering the sewing foot. 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 the machine or to remove the material from under the presser foot in an emergency once 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, hand lever lock disengages and the internal spring moves the hand lever back to position (0). 5.11 Setting presser foot pressure The regulator on the top left of the machine arm determines the pressure the presser foot applies to the material. The pressure can be adjusted continuously by turning the regulator.
Operation Fig. 24: Setting presser foot pressure ི + ཱ (1) – Adjusting wheel (2) – Counternut (3) – Auxiliary spring To increase presser foot pressure: 1. Release counternut (2). 2.

If the pressure is insufficient even when the regulator is fully tightened, use the auxiliary spring (3) provided in the machine accessories. 4. Completely loosen regulator (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. Tighten regulator (1) and set presser foot pressure. 7. Tighten counternut (2). Reducing pressure: 1. Loosen counternut (2). 2.
Operation 5.12 Setting presser foot stroke The presser foot stroke has 12 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 material thickness according to the table, Table: Maximum presser foot stroke, p. 99.
Operation Fig. 25: Presser foot stroke adjusting wheels ཱ (1) – Adjusting wheel for normal presser foot stroke (2) – Adjusting wheel for increased presser foot stroke To increase presser foot stroke: 1. Turn adjusting wheel clockwise. To reduce presser foot stroke: 1. Turn adjusting wheel counterclockwise. Operating Manual 967 version 00.
Operation 5.12.4 Quickly switching presser foot stroke with foot switch If the machine is equipped with an optional foot switch, it can be used to quickly switch presser foot stroke between two preset levels without having to stop sewing.

Operation Switching stitch length: Stitch length can be switched between the values set on the adjusting wheels (3) and (4) while the machine is off or on. 1. Press the key (1). Stitch length switches from the current length to the second length and the key illuminates/turns off. If the key illuminates, the longer length set on the top adjusting wheel (4) is in use. 5.13.3 Reverse sewing and seam bar tacking On Eco machines, seam bar tacking can only be done by hand.
Operation Manual seam bar tacking: 1. Move stitch regulator (5) to the bottom. The machine feeds the material in reverse as long as the regulator is depressed. Partially depressing the stitch regulator (5) shortens the stitch length in proportion to the distance of the regulator from its middle position. In middle position, feed is stopped completely. In the lower end position, the machine sews in reverse with the stitch length is selected using the adjusting wheels.
Operation 3. Finish the seam, then press the operating pedal (3) completely back at the end of the seam. Machine automatically sews a bar tack at the end of the seam. Selecting type of seam bar tacking and stitch count with automatic seam bar tacking: The machine's control unit allows selection between a single, double or multiple (quadruple) bar tack. The type of bar tack is selected using the keys on the OP1000 control panel – see Operating manual for eco/classic DAC control unit.
Operation 5.14 Quick functions on keypad Depending on the submodel, the machine has a keypad on the machine arm for activating specific functions while sewing. 5.14.1 Activating function keys Fig.
Operation Fig. 31: Function keys Key Function Reverse sewing key (2): When this key (2) is selected, the machine sews in reverse. Needle positioning key (3): When this key (3) is selected, the needle moves to a specific position. This position is determined individually via the parameter settings. The machine comes configured so that selecting the key (3) will bring the needle up.
Operation 5.14.2 Transferring a key function to the auxiliary switch You can transfer one of the key functions to the auxiliary switch. Select a function that you frequently use to be able to switch it on faster while sewing.
