    Hints for repair and settings A t t e n t i o n , danger! Observe safety and operating instructions before realizing any maintenance and repair works. Failure to do so may result in heavy bodily injuries. Mounting the needle plate A t t e n t i o n ! Switch off machine electrically! Needle plates are set at works and can be replaced easily as complete kit.

  • Page 15: Remounting The Needle Plate

    Fig. 1 3.1.2 Remounting the needle plate Remount the needle plate in reversed order. 3.1.3 Setting the needle plate (Fig. 1) The theoretical needle radius of 43.6 mm should be 0.01 - 0.04 mm smaller at the needle slide plate; in other words, a checked needle is raised by 0.01 - 0.04 mm.

  • Page 16: Adjusting The Needle

    3.1.4 Adjusting the needle A t t e n t i o n ! Switch off machine electrically! The needle is adjusted in a lateral direction so that it is situated centrally in relation to the needle plate (i.e. between the two screw holes). 3.1.5 Replacing the needle slide plate (Fig.

  • Page 17: Needle Lever

    Needle lever A t t e n t i o n ! Switch off machine electrically! 3.2.1 Setting the needle lever path (Fig. 1) After removing the head cover and the thread tension adjustment button, the needle lever must be turned down so far, that the eccentric bolt (1) can be reached with a screw driver through the hole provided in the head.

  • Page 18: Stroke Of Loop

    Stroke of loop Stroke of loop means the needle race from its lowest position to the spot where the lower point is placed on top of the center of the needle. 3.3.1 Setting the needle stroke (Fig. 3) A t t e n t i o n ! Switch off machine electrically! Normally is a loop stroke of 2.8 mm.

  • Page 19: Looper

    Looper 3.4.1 Removing and re-mounting the looper (Fig. 3 + Fig. 4) A t t e n t i o n ! Switch off machine electrically! Dismantle the following parts: Cover (rear of head), needle, needle plate, angle lever (2) (Fig. 4) with bolt (5) and spring (1) (Fig.

  • Page 20: Setting The Shuttle In Relation To The Needle (Fig. 5)

    3.4.2 Setting the shuttle in relation to the needle (Fig. 5) The gap between the shuttle tip and a 90 needle must max. 0.2 mm. If it is necessary to adjust the shuttle, then this is done by slackening the cylinder head screw (1) and turning the eccentric bushing (2).

  • Page 21: Thread Tension - Bobbin Thread (Fig. 7)

    3.4.4 Thread tension - bobbin thread (Fig. 7) The leaf spring (2) regulates the bobbin thread tension. By turning the flat-head screw with catch (1), the leaf spring must be adjusted in such a way that when the bobbin is inserted, and the thread is correctly pulled under the leaf spring and the bobbin case is released, the latter, together with the bobbin, drops slowly down.

  • Page 22: Feed Motion

    3.5.1 Feed (bottom feed) (Fig. 9) The machine cl. 218D-TP-R is factory-fitted with a pyramid-teethed feed (3). 3.5.2 Setting the feed motion (Fig. 8) The feed cam (1) on the main shaft must be set so that feed begins when the eye of the needle is located 5 ±1 mm before centre of the plunger on its return...

  • Page 23: Presser Plate

    Presser plate When the initial stitch is made, the presser plate presses the sewn item from below against the needle plate. During feed, the presser plate should life 4 - 5 mm from the needle plate when working with thick sewing material, and 2.5 mm when working with thin to medium sewing material.

  • Page 24: Plunger

    Plunger The plunger forces the sewn material from underneath into the needle plate opening, so that the needle can penetrate the sewing material. 3.7.1 Removing the plunger (Fig. 10) A t t e n t i o n ! Switch off machine electrically! Unscrew threaded screw (2) with plunger check screw (3), until it is flushed with the plunger sleeve.

  • Page 25: Fitting The Plunger (Fig. 10)

    3.7.2 Fitting the plunger (Fig. 10) Fitting takes place in reverse order. However, the following points must be observed for precise adjustment: the cylindrical pin (1) must engage in the groove of the plunger sleeve. Turn stitch-depth adjustment knob (1) (Fig. 12) clockwise, as far as the stop (highest position).

  • Page 26: Adjusting The Digital Stitch Depth (Fig. 12)

    Fig. 11 3.7.4 Adjusting the digital stitch depth (Fig. 12) If the adjustment knob (1) is turned clockwise as far as the stop, the toothed wheel (6) must be screwed tightly onto the shaft of the helical potentiometer so that a value of between 003 and 006 is displayed on the digital display, and the distance to the toothed wheel (4) is approx.

  • Page 27: Setting The Plunger Lowering (Fig. 13, Fig. 14, Fig. 15)

    Setting the plunger lowering (Fig. 13, Fig. 14, Fig. 15) For larger sewing material thickening, sometimes the stitch depth of a stitch should be reduced over a shorter or longer section. By adjusting the scale on the right of the stand, the plunger can be lowered from 0 to up to 3.8 mm by pushing a button.
  • Page 28 Set the plunger to the highest possible point and adjust the eccentric (1) (Fig. 14) to approx. 15° at the stop of scale (2) (Fig. 14) at pin (3) (Fig. 14). Fix the scale in this position on the eccentric. Fig.
  • Page 29 Lever (1) (Fig. 15) on which the cylinder hangs must be set so that there is a free space of at least 0.5 to 1 mm between piston rod and eccentric (2) (Fig. 15). Secure lever (1) (Fig. 15) in this position on the eccentric with both threaded screws.

  • Page 30: Thread Spreader

    Thread spreader It is possible to produce a cross-stitch using the thread spreader. The two fingers of the thread spreader take hold of the thread between the sewing material and the eye of the needle and place it under slight tension, at an angle to the movement of the needle, in a groove in the needle plate.
