Machine cover
The machine cover protects the machine from dust and dirt. When the sewing process is finished, push the telescopic thread guide 32 together. The spool stand 34 must be pushed to its full extent in to the machine, regardless of whether a spool is attached. Place the cover over the machine.
The accessories should be stored in the accessory box or compartments behind the swivel plate.
8
Connecting the foot control
Connect the plug of the foot control to the connection socket 39 of the machine. The sewing speed is regulated by activating the foot control. You may also regulate the sewing speed by adjusting the slide on the front side of the foot control.
Setting 3 = half of final speed Setting 8 = full final speed
Electrical connection
Connect the foot control cord with the wall outlet.
Foot controls to be used:
AE040 - EU
AE044 - Australia
AE046 - United Kingdom
AE043 - USA/Canada
For the USA and Canada
This appliance has a polarized plug (one blade wider than the other).
To reduce the risk of electric shock, it is designed to fit into a plorized outlet only one way. If the plug does not fit correctly into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet.
Do not modify the plug in any way.
Master switch
When you turn on the master switch 38 the sewing lamp is illuminated. The machine is now operational.
9
Waste container
Insert the upper latch of the waste container 45 into the upper slot of the looper cover 7.
Apply pressure to the lower part of the container until the lower latches flick into place in the lower slots of the looper cover.
Looper cover
Push the looper cover 7 fully to the right and then swivel it down. Five types of stitches and their threading paths are portrayed in color on the inside of the looper cover.
Note: The electricity supply of the machine is cut off as soon as the looper cover or swivel plate 12 is opened, for safety reasons, i.e. sewing with the machine is no longer possible.
To remove the waste container, repeat this procedure in the reverse order.
10
Spool holder
Before placing thread cones/spools on machine you must pull the spool holder 34 fully away from the back of machine.
Thread net
Synthetic threads generally unwind too quickly from the thread spool. Thread nets have been included to allow easy use of these threads. Pull the thread net (located in the accessory box) over the spool from below. Place the spool on the spool holder catching the bottom of the thread net with the spool pin.
Telescopic thread guide
Pull the telescopic thread guide 32 upwards to its highest position.
To ensure optimum thread feed, turn the telescopic parts slowly until you hear the locking balls flick into place.
Thread unreeling disc
The thread unreeling disc (in the accessory box) is used for small spools/spools with notched or rough ends. Place the spool on the spool pin 35. Place the thread unreeling disc on top of the spool. Make sure the spool dise 37 is used under the spool.
11
Spool disc/cone thread adapter
It is advantageous to use the spool dise
37 when sewing with large spools (5,000 10,000 m). To do this, place the cone thread adapter 36 onto the spool pin 35. With synthetic threads, the spool discs help eliminate vibration of the cones/spools aiding in smoother feeding of the threads.
Presser foot lifter
The presser foot can be raised and lowered using the presser foot lifter 43. The maximum vertical lift of 6.5 mm for the presser foot for particularly thick fabrics can be achieved by pressing the presser foot lifter towards the rear.
Clip on thread guide
Use the clip on thread guide accessory when sewing with decorative thread. Clip this onto the telescoping thread guide 32 and thread the machine as shown in the illustration. Use the thread net and/or the thread unreeling disc if needed.
Once an initial thread chain has been created, the presser foot lifter no longer needs to be raised if you continue working with the same thread and presser foot. It is sufficient to gently lift the front part of the presser foot using your thumb. Slide the fabric under the raised part of the presser foot. The fabric is automatically taken up and fed into the machine when you activate the foot control.
12
Presserfoot
With standard presser foot 10 use setting ”A” on the spring loaded presser foot latch for the cover stitch (Prog. 02), the 2 thread chainstitch (Prog. 01), the 5 thread safety stitch seam (Prog. 09) and the 4 thread safety stitch seam (Prog. 08).
Transparent presser foot F from the accessories can also be used for the cover stitch (Prog. 02).
For all other programs use standard presser foot 10 and setting ”B” on the springloaded presser foot latch.
Changing the presser foot
Switch off the electrical power
To remove: Raise the needle(s) to the highest position by turning the hand wheel towards you. Raise the presser foot and press lever A at the rear of the presser foot holder. The presser foot will be released automatically from the holder. Pivot the presser foot clockwise until the front half of presser foot clears holder and remove by sliding foot away from you towards back of machine.
To attach: Place the presser foot behind and perpendicular to the presser foot holder. Pivot the presser foot counterclockwise until the pin of the foot is directly under the
presser foot holder clamp. Lower the presser foot lever and press lever A, if necessary, until the foot then clicks into place.
Check: Please lift the presser foot lever to ensure that the presser foot is properly locked into place.
13
Needle position
This machine has 4 needle positions and can sew with a maximum of two needles at any one time. The needle positions are 1 1, L2, R11 and R2. The fastening screw is located directly above the corresponding needle.
Note: If the needles 1 11 and L2 have been inserted, the left needle will be somewhat lower than the right needle.
The different needle positions are depicted in a schematic drawing in the instruction manual. Also refer to the examples above and below. Insert the needle(s) as shown on the program overview (see pages 40-43).
Note: If the needles R2 and 131 have been inserted, the left needle will be somewhat higher than the right needle.
14
Changing the needle
Switch off the electrical power
To remove: Lower the presser foot and move the needle(s) to the highest position by turning the handwheel towards you. Push the needle inserting tool (from the accessory box 49) from below upward fully over the needle. Loosen the fastening screw of the needle (without removing it) with the Allen key (behind the swivel plate) and pull the needle down to remove.
To insert: Insert the needle into hole E of the needle inserting tool, so that the flat needle shank K faces the flat side L of the inserting tool. Insert the needle fully into the holder and tighten the fastening screws. Remove the needle inserting tool.
Overlock needles types EL X 705, cat. no. 2002 are required for this machine.
15
Threading the thread guides
Place the spools on the spool pins 35. You will find information on the thread net, thread unreeling disc, spool disc and cone thread adapter on pages 9 and 10. Thread through the thread guides 31 from the back to the front following the colored threading paths.
Lift the carry handle 3 upwards. Thread through the underside of the carrying handle and through the rear thread guides 44 using both hands to pull the thread down until
it slips under the thread guide. Guide the thread through the tension discs and pull it down until it is positioned firmly between the tension discs. Return the carrying handle to its original position.
