To clean the housing and display of your PFAFF HOBBYLOCK 4860, use a dry, clean, and soft cloth which is free of fluff. To remove any stubborn dirt, use a soft cloth with alcohol or paraffin.

Please Note: Never use insecticides or chemical products such as petrol (gas) or thin chemicals to clean the housing.

Electrical Connection:

Connect the mains cord between the power socket (28) of the sewing machine and the wall socket.

Connecting the Foot Control:

Connect the plug of the foot control with the connection socket (30) of the sewing machine. The preset area of the sewing speed is regulated by pressing the pedal.

Caution: Do not put anything under the pedal.

When the main switch (29) is turned on, the sewing light and display (6) will turn on. The machine is now operational.

The free arm is particularly suited to sew tubular goods without any difficulty. To use it, pull the detachable work support (17) to the left. Insert the workpiece in the opposite direction.

To remove:

Grip in the recess beneath the accessory box (19) and pull it out in the direction of the arrow.

To open:

Open the accessory box (19) by pressing the two points marked “A”.

To insert:

Push the accessory box (19) into the appropriate opening until it catches. The words “PFAFF hobbylock” must be facing upwards.

1. Before the spools are attached, you must pull the spool stand (27) out fully in the direction of the arrow.

2. Extend the telescopic thread guide (23) fully.

3. To assure optimal thread take-up, the two upper telescopic extensions must be turned slowly until you hear the ball stops catch in place.

4. When you have finished sewing, push in the telescopic thread guide (23) and push the spool stand (27) in towards the machine, with or without the spools, until it catches in place.

To attach the waste box, insert the tabs on the waste box (46) into the notches on the looper cover (13) and press it down against the looper cover until you hear it catch in place. To take it off, reverse this process.

Push the looper cover (13) to the right until it catches in place and then swivel it down to open it. The individual threading paths and the converter setting are illustrated in colour on the inside of the looper cover.

When the machine has been threaded, you must close the looper cover (13) to operate the machine.

Note: The power supply is interrupted when the looper cover is open, so it is not possible to sew. “Close looper cover” will appear in the display, and the LEDs for the preset speed will flash.

1. Place thread spools on the spool pins (24). For smaller spools, it is recommended to attach a thread unwinding disc to the spool with the rounded end to the bottom.

2. Thread the thread guides (22) according to the color-coding.

3. With both hands, pull the thread through the thread guide (35) and the appropriate thread tension (1, 2, 4, 5).

4. Make sure the thread stays in the slot on the back thread guide (35). Set the thread tension to “N” and thread as indicated by the color paths:

1. Right overedge looper (pink)

2. Left overedge looper (yellow)

3. Right needle (green)

4. Left needle (blue)

Note: To achieve top sewing results, make sure that the thread is pulled between the tension discs when threading.

The slider on the converter (37) must be in the right-hand position B. Thread the right overedge looper (36) in the order 1 to 9, following the thread path marked in pink. Draw the thread to the left under the sewing foot.

1. Turn the hand wheel until the marking on it is in line with the marking on the housing.

2. Thread the left overedge looper (38) in the order 1 to 7, following the thread path marked in yellow. Pull the thread from thread guide 7 through the looper eye 8 and pull it a bit with your left hand.

3. Pull the end of the thread slightly and push the slider on the looper threader (39) to the left until it rests in place.

4. Pull the thread a bit more and at the same time let the slider slowly slide back. The thread is automatically inserted in guide 9.

5. With the tweezers, thread the thread through thread guide (10) and draw the thread to the left under the sewing foot.

Note: If the slider on the threader (39) cannot be moved, the marking on the hand wheel is not correctly set.

1. Lower the sewing foot with the sewing foot lever (32) and turn the hand wheel (31) until the needle is in its highest position.

2. Place the threader from the accessories with the needle between the two guide lugs B. Draw the thread through slot A on the threader and hold it a bit taut.

3. Slowly lower the threader behind the needle until the small hook C passes through the needle’s eye. Draw the thread from the bottom through hook D and the thread will automatically pass behind hook C.

4. Draw the threader back away from the needle’s eye. You can now pull the end of the thread through the eye to thread the needle.

Note: When threading the needles, make sure that the sewing foot lever (32) is in its highest position. This automatically releases the needle thread tensions and makes it easier to thread the needles.

Threading overedge needle A (left needle):

Thread the overedge needle A in the order 1 to 6. Draw the thread through the needle’s eye 7 with the threader. Draw the thread to the left under the sewing foot. The threading path for needle A is in blue (dots).

Threading overedge needle B (right needle):

Thread the overedge needle B in the order 1 to 6. Draw the thread through the needle’s eye 7 with the threader. Draw the thread to the left under the sewing foot. The threading path for needle B is in green (dots).

Cut the threads off close to the thread spool and put on the new spools. Tie the ends of the old thread and the new thread together. Pull the needle threads out of the needles. Lower the sewing foot. Now pull the threads through until the knots are about six inches through the thread guide before the needles. Cut the knots off and thread the appropriate needles. You can also draw the looper threads straight through the looper eye and to the left under the sewing foot. It is easier to pull the looper threads if you turn the looper tensions (4 and 5) to -5.

The sewing foot is raised and lowered with the sewing foot lever (32).

1. When the machine has been threaded, you should sew a test seam. First, raise the sewing foot.

2. Place a fabric remnant under the sewing foot right in front of the needle and lower the foot.

3. With the threads held slightly taut, slowly begin to sew. Since the fabric is automatically fed, you just need to guide the material with your hands (do not push or pull).

Note: Make sure that the threads interloop correctly when sewing (thread chain).

To use the thread cutter (25), you must sew over the end of the seam. Draw the thread chain that results to the front over the thread cutter.

There are various ways of securing the ends of seams:

1. Knot the thread chain.

2. With knitwear, you can pull the thread chain into the seam with a crochet needle.

3. Sew about 2 inches over the end of the seam. Turn the sewing round and sew back a few stitches in the opposite direction without cutting the thread chain.

The seam width adjusting knob (16) is released if it is pressed to the right. You can now set the seam width you require as indicated in the window (18). The range is from 3 to 5 mm and is infinitely variable. The standard setting N is 3.5 mm.

When you have set the seam width you require, press the knob to the right until it catches in place, as indicated by the arrow. This prevents the seam width being inadvertently changed while sewing.

Note: The seam width settings 3 to 5 are just for needle B (right needle). If needle A (left needle) is used, the amount that is set is increased by 2.2 mm (to a range of 5.2 to 7.2 mm).

Note: The upper knife must be locked when sewing very thick fabrics or fabrics with different thicknesses.

You can set the required stitch length by turning the stitch length adjusting knob (33). The setting is displayed in the window (7). The range is from 1 to 4 mm and is infinitely variable. The standard setting N is 3 mm.

The differential feed consists of two feed dogs that ensure the fabric is fed evenly and prevents displacement of fabric layers. The feed dogs can be set separately. You can set the differential feed by turning the adjusting ring (34). The range from 0.5 to 2 is infinitely variable and is indicated in the window (8).

The following settings can be set with the knob:

Position 0.5: front feed dog shorter movement, rear feed dog longer movement (creates a wavelike effect on rib knit).

Position N: same movement of feed dogs.

Position 1.5 – 2: front feed dog longer movement, rear feed dog shorter movement (creates a gathering effect on light fabrics).

The following table shows possible settings for the differential feed. Sew a test seam to determine the correct setting for your fabric. The differential feed can also be set while sewing.

First, switch off the main switch.

To remove:

1. Lower the sewing foot and put the needle in its highest position.

2. Push the needle changing aid (from accessories) from below right up until it catches over the needle.

3. Loosen set screws (A or B) with the red screwdriver and pull the needle down to remove.

To insert:

1. Insert the needle into the hole E of the needle changing aid, with the flat needle shank K facing towards the flat side L of the aid.

2. Insert the needle until it catches in place in the holder and tighten the needle set screw.

3. Remove the needle changing aid.

1. Lower the knife to the lowest position with the hand wheel.

2. Now turn the knob to disengage the upper knife (40) fully to the left (triangle on O).

3. The knife is now disengaged.

For extremely thick fabrics, you must tighten the axial lock screw on the upper knife with the large screwdriver from the accessories. This prevents the knife from being displaced by the material. Before doing this, remove the sewing foot and needle plate.

To sew light fabrics, the screw must be loosened by about two turns so that the knife can again move in an axial (sideways) direction.

Note: The screw for the upper knife must be loosened to change the cutting width.

You can change the sewing foot pressure depending on the thickness of the material with the lever (21).

Position 1: sewing foot pressure for very thin fabric.

Position N: sewing foot pressure for medium thickness fabric.

Position 3: sewing foot pressure for very thick fabric.

A serging seam is generally sewn with 3 threads. If you connect the converter, you can dispense with one thread and continue to sew with 2 threads, saving thread. A 2-thread seam is sufficient for elastic materials and materials that hardly fray. You can also make very effective fancy seams with the converter using mercerized cotton.

All seams that are sewn with the converter (37) are only sewn with the left looper thread (yellow thread path) and with one needle thread. The exception is Program 9, which is sewn with two needle threads and the left looper thread.

To switch on the converter:

1. Turn the hand wheel until the right overedge looper (36) is situated to the right of the needle.

2. To use the converter (37), you must cut off the right looper thread and pull it out of the looper eye.

3. The left hand thread that runs over the right looper must be pulled over the point of the right looper in the direction of the arrow.

4. Push the slide of the converter to the left until the triangles are in line. The point of the slide catches into the eye of the looper. This is position A (converter switched on).

To switch the converter off:

1. Turn the hand wheel slowly until the left hand looper thread jumps from the point of the right looper.

2. Switch the converter (37) off into position B.

3. Thread the right looper.

This applies to Program 1 or 2 (2-thread overlock seam, narrow or wide, FLATLOCK).

If looper thread E is too tight (yellow tension) or needle thread F is too loose (green or blue tension):

The two thread tensions must be turned accordingly to + or -.

If looper thread E is too loose (yellow tension) or needle thread F is too tight (green or blue tension):

The two thread tensions must be turned accordingly either to + or -.

A rolled/flat hem (Programs 3, 6, 13, or 16) is used for light, thin fabrics and also creates a decorative edge.

To do so, just convert the machine as indicated in the display for the selected program.

The rolled hem can only be sewn with needle B (right needle), and you must also replace the needle plate N with the rolled hem plate R.

The best suited threads are textured thread (bulk thread) as well as polyester thread. Only textured thread should be used for the looper.

For a 2-thread flat hem (Prog. 3) or 2-thread rolled hem (Prog. 13), the converter must be switched on.
