Threading the guide wire of the thread spool stand and the thread guides behind the carrying handle

The machine must be threaded correctly. First pull the respective threads through their corresponding guides (Figs. B and C).

Then thread the tensions in the following sequence:

  1. right looper (red)
  2. left looper (yellow)
  3. right needle (green)
  4. left needle (blue)

Figure B shows the threading path of the individual threads for thread guides 18. For threading the guides behind carrying handle 2, the handle must be pulled up (Fig. C).

After threading, carrying handle 2 must be pushed down again.

4-thread overedge seam

This seam is sewn with two needle threads and two looper threads.

The 3-thread overedge seam is described on page 17.

Threading the right looper:

Thread the right looper in sequence 1 to 9 and pull approximately 10 cm (4") of thread through the looper eye (the thread path is marked red).

Important: In order to obtain perfect sewing results, the thread must be pulled between the tension discs when threading the tensions.

Threading the right needle

Threading of guide wires 18 and of the thread guide behind the carrying handle is shown on page 7.

In the left-hand illustration the threading path is shown from the green tension (1) up to the right needle (6). At point 5 the thread must be pulled behind the thread retainer.

Threading the left needle

Threading of guide wires 18 and of the thread guide behind the carrying handle is shown on page 7.

In the left-hand illustration the threading path is shown from the blue tension (1) up to the left needle (6). At point 5 the thread must be pulled behind the thread retainer.

Thread spool change on threaded machine

Cut the threads close to the thread spool. Place new thread spools on spool holders 17. Tie the threads still in the machine and the new threads together. Pull the needle threads out of the needles. Now pull at the thread ends until the knots are about 15 cm past the last thread guide before the needles. Cut the knots off and pull the threads through the respective needle eyes. The looper threads can be pulled until past the looper eyes without interruption. Pull about 10 cm of thread through the looper eye.

Points to observe during sewing

Place the fabric completely under the sewing foot when starting to sew. (Also after the machine has been rethreaded.)

Sew the first stitches slowly.

Since the fabric is fed automatically, do not pull or push the fabric. Use your hand for guiding only.

natural_image Line drawing of a sewing machine needle stitching fabric (no text or symbols)

Sew approximately 5 cm beyond the end of the seam and use a scissors to cut the thread chain.

PFAFF hobbylock 786 - Points to observe during sewing - 2

natural_image Line drawing of a sewing machine needle stitching a fabric, showing hands operating the mechanism (no text or symbols)

Securing the seam:

Knot the thread chain. For knit fabrics, a crochet needle can be used to pull the thread chain into the seam.

Or:

Sew about 5 cm (2") beyond the end of seam. Then turn the workpiece around and sew a few stitches over the seam just sewn without cutting the thread chain.

Blocking the upper knife

Sewing very thick fabrics and workpieces with different thicknesses:

On this machine, all kinds of fabric from extremely thin to extremely thick can be processed. When sewing extremely thick fabrics or workpieces with different thicknesses, the screw of the upper knife must be tightened, as shown in the illustration.

By tightening the screw, axial movement of the upper knife is inhibited.

Note:

When sewing thin or medium fabrics, the screw of the upper knife holder must be loosened by about 2 turns, so that the upper knife can move axially.

Setting the standard thread tension N

The thread tension to be set depends on the fabric type and thread size used.

Set the N on the thread tension dials opposite the round symbol (see illustration below).

Make the correct adjustment after examination of the interlocking of threads (the illustration on the left shows a correct seam).

Page 16 lists examples for correction of the individual thread tensions.

Adjusting the differential feed on the hobbylock 786

The differential feed prevents inter-ply shift. It consists of two feed dogs, arranged one behind the other, which both pick up and move the workpiece at the same time.

The feed amount of either feed dog can be set separately. It is possible to have the workpiece moved more by the front feed dog than by the rear one and vice versa. Owing to that very good sewing results are accomplished. Set the differential feed according to the material you wish to process (see table on page 20). The following settings at button 23 are possible:

Setting 0.5 = Short stroke of front feed dog, long stroke of rear feed dog

Setting - N = Same stroke of both feed dogs

Setting 1.5 = Long stroke of front feed dog, short stroke of rear feed dog

Setting 2 = Front feed dog set for longest possible stroke, rear feed dog set for shortest possible stroke

The differential feed can be set infinitely from 0.5 to 2, also during sewing.

Note:

The following variants can be employed to obtain fashionable effects on garments:

The gather effect is obtained at a differential feed setting of 1.5–2 when light fabrics are processed.

The wave effect is obtained at a differential feed setting of 0.5 when medium to heavy elastic fabrics are processed.

This table indicates possible settings of the differential feed. In order to make sure about the setting required for the fabric you wish to process, a sewing test has to be made.

The differential feed can also be set during sewing.

Pull out the mains plug. Lower the sewing foot. Turn the hand wheel in the direction of the arrow until the needle bar is at its highest position. Use the needle change tool from the accessories (see p. 31, item 11) as follows: Insert the needle in hole M of the needle change tool. Loosen the set screw of the needle with the screw driver. Remove the needle by pulling it downwards.

Inserting the needle

Insert the needle in hole M of the needle change tool in such a way that flat side K of the needle shank faces surface L of the needle change tool. Then push the needle up into the needle holder as far as it will go.

Tighten needle set screw securely. Remove needle change tool from the needle.

Notes:

The following needles are used on these machines: System 130/705 H (75–90)

Although the correct needle size depends on the material and the thread size used, we recommend needle size 75–90.

An incorrectly inserted needle will cause thread breakage and skipped stitches.

Align the cutting edge of the lower knife so that it is flush with the needle plate surface.
Before tightening the retaining screw, align the pressure plate. Reset the upper knife to cutting position.

Oiling the machine:

Every time before you take the machine into operation, you should apply a little oil to the places indicated. The bushings and other important moving parts are made of special material and need to be oiled only once or twice a month. One to two drops of high-quality sewing machine oil are sufficient for oiling.
