Main clamp 1.1 Clamp drive belt The clamp must stand in home position (like shown in the upper picture). The drive belt (1) must have enough tension that it gives about 15 mm when loaded with 1 kg (in the middle between both belt disks). If required, loosen both fixing screws (2) and adjust the set screws (3). Tighten the fixing screws (2) again.
1.2 Adjust axial free play of the clamp arms The clamp arms (1) must be adjusted without free play. Although they have to move easily. Check the correct adjustment from time to time. If required, you can adjust the axial free play of the clamp arms with the screws (2). 1.3 Parallelity of the clamp arms to the sewing head This is adjusted in the factory and doesn’t have to be changed. 1.
1.6 Adjust main clamp height The main clamp height in insertion position must be 30 mm. To adjust this, loosen the nuts (1) at both clamp pressure cylinders and turn the piston pole (2) until the must height is present. 1.7 Adjust main clamp pressure The clamp pressure must be 3.5 bar. You can read it at the pressure gauge (1) on the clamp carriage. To adjust the pressure, pull out the black knob and turn it into the required direction. Press the knob down again. 1.
1.9 Clamp quick adjustment double/ single piping (option) An initiator is mounted at the insertion station, which recognizes the folder for double or single piping. The main clamps will be driven into the correct position dependant on the inserted folder. These positions are adjustable. Mount the folder for the double piping and move both inner setting rings (1) in a way that there is a distance of 1.5 mm between sole edge and main clamp edge (see lower picture).
1.11 Lateral clamp adjustment without quick adjustments Mount the folder for the double piping. Adjust the inner setting rings (2) (3) in a way that there is a distance of 1.5 mm between main clamp and sole. Mount the folder for single piping. Move clamp and setting rings (3) (4) to the outside until there is a distance of 1.5 mm between folder and sole. Now block the lateral escape of the clamp arms by fixing the setting rings. 1.
1.14 Adjust parallelity of folding slide In driven in state, the folding slide must be parallel to and 0.5 mm away from the edge of the main clamp. This can be adjusted with the fixing screws of the folding slide cylinder (1). 1.15 Adjust folding slide A turn movement of the folding slide must be assured which allows him to adjust to the strength of the sewing material. Adjust the screws (1) to adjust the folding slide with no free play axially. 1.
1.17 Opening path of the flap clamp The opening path of the flap clamps (4) must be adjusted in a way that the flap clamp presses with its complete length onto the main clamp, when the flap clamp cylinder is driven out. Loosen both allen screws (1) at the flap clamp to be adjusted and adjust the cylinder (2) correctly. Tighten both allen screws (1) again. 1.18 Photo cell foil A photo cell foil (5) is fixed to each clamp (3). This allows an always good detection of the flap.
1.20 Adjust clamp path 1.20.1Adjust front stop Drive the clamp carriage (1) into insertion position intil initiator 1 (2) switched dark. The distance (A) between the beam and the clamp carriage must be 19 mm. To adjust the distance, loosen the fixing screws of the initiator 1 (2) and move him in the desired direction.

Loosen the fixing screws in the mounting frame (see section 3.1) and level the sewing head exactly.
3.4 Top threat cutter (Beisler sewing head) The toip threats will be caught by the top threat catcher after the sewing during the clamp drives to the mitre cutting. The threats will first be clamped on the top side of the catcher and then cut on the backside. The threat clamp must hold the threats during the first stitches of the seam start to assure a clean sewing image at seam start. 3.
3.6.5 Height of center knife The front edge of the center knife (1) must stand (in switched on state and deepest position) 1 mm deeper than the top side of the stitch plate. To adjust it, loosen both fixing screws (2) and move the center knife. Tighten both screws again. 3.6.6 Shear angle of the center knife The center knife should stand slightly folded against the counter knife in the stitch plate.
3.7 Adjustments of the bobbin threat catcher (Beisler sewing head) 3.7.1 Catcher adjustment Turn the belt disk manually until the spool capsule lever stands as far as possible back into arrow direction. Fix the movable knife (4) temporarily with the screw (3) and press manually onto the top side of the knife (4) to move it. Tighten screw (3) when the distance between the top of the movable knife to the holder of the catcher is netween 0.05 and 0.2 mm.
3.9 Clean tactual head of the bobbin detector (option) There is a blowing system at the bobbin detector which blows the tactual head free of dirt. Clean the tactual head (1) with a clean and lint-free cloth from time to time. 3.10 Adjust piping detection 3.10.1Lateral adjustment The photocell (1) is equipped with a red light point (4 – illustrated by drawing), which indicates the exact switch point on the folding slide.
3.11 Swing up sewing head The sewing head can be swung up. First you will have to demount several parts: spooler, position actuator, belt protector; push sliding plate to the left. Loosen screw (1) and swing the sewing head upwards. Use the support (2). DANGER During maintenance duties at the swung up sewing head, the support must be locked completely at the oil reservoir. Otherwise it can slip away and the sewing head can cause severe injuries. 3.
4 Adjustments at the mitre knifes 4.1 Basic adjustment locked mitre knife (seam end) Between the mitre knife for the seam end and the basic holder a distance (A) of 21 mm must be adjusted. Loosen both screws (6 in this and in the picture at section 4.2) and move the mitre knife axially. Tighten both screws again. 4.2 Basic adjustment movable mitre knife (seam start) When the movable knife for seam start (1) has contact to the locked mitre knife, the distance between both holders must be 3 mm.
4.5 Pre-stabber The pre-stabber (3) at the mitre knifes is used as a protection. It prevents the piping and the flap to be damages during cutting. 4.6 Lateral adjustment To achieve an exact mitre knife cutting, the knifes must be adjusted also laterally.
