7. 7.1 Machine operation Needle threading A A B C Attention! Danger of injury! Thread when the main switch is switched off and motor stopped! – – 12 Do the threading according to picture (A) and detail (B). When trimming the material edges, do the threading according to picture (A) and detail(C).
7.2 Hook thread winding A A 3 1 5 GB 4 2 B 3 2 – – – – – – – Fix the bobbin (1) on the winder. Do the threading according to picture (A), wind 5 times round the bobbin. Insert the thread under cutter (2) and tear off by pulling in the arrow direction (3). Pull the lever (4) in the arrow direction (5). Start the machine up. After the bobbin winding, wind the thread round the cutter (2) according to picture (B) and tear it off by pulling in the arrow direction (3).
7.3 Bobbin fixing and hook threading 8 6 5 2 3 4 2 1 2 7 Attention! Danger of injury! Switch the main switch off and wait for the motor stopping. – – – – – 14 Tilt the flap (1), grip it and pull the bobbin case (2) out of the hook. Put the bobbin (3) in the bobbin case with the thread end (4) oriented according to the picture (2). Draw the thread end (4) through the slit (5), pull under the spring (6) and pull into the slit (7).
7.4 7.4.1 Thread tension adjustment Needle thread tension adjustment 1 2 Secondary tensioner adjustment (1) – Adjust the secondary tensioner (1) so that it has as small tension as possible, but high enough so as the thread cannot be pulled out from the tensioner (1) at the material removing after previous trimming (when the tensioner (2) is opened - switched off). (The tensioner (1) is never switched off).
7.4.2 Hook thread tension adjustment 7 3 2 7 A B 8 4 6 1 5 C Attention! Danger of injury! Do adjustments when the main switch is switched off and motor stopped! – The hook thread tension depends on the adjustment of springs (1) and (2). Tension spring (1) adjustment – Remove the bobbin case (3) from the machine and insert a full-wound bobbin (4). – Do a complete threading according to picture (B).
7.5 Needle replacement 1 3 2 D Attention! Danger of injury! Do the needle replacement when the main switch is switched off and motor stopped. – – – GB Loosen the screw (1) and remove the needle (2). Fix a new needle and turn it so that the needle scarf (3) is oriented according to detail (D). Tighten the screw (1).
7.6 Foot lifting 1 2 3 Foot lifting with a hand lever – Lift the foot by pressing the lever (1) to a stop (foot remains lifted). – Lower the foot by returning the lever (1) to initial position or by pressing the knee lever (2) /if there is any/ and by its subsequent releasing or by the automatic foot lifting by means of the pedal and subsequent pedal releasing. – After the foot lifting by hand lever, the machine may be started up (e. g. when winding the hook thread).
7.7 Foot pressure setting 1 – – – Regulate the foot pressure by means of a screwdriver (1) which is supplied with the machine accessories. The pressure increases by turning in the arrow direction and vice versa. The foot pressure should be as small as possible, but strong enough so that the feeding is reliable even at a high sewing speed. – 7.8 Stitch length setting 3 2 1 – Turn the knob (1) so that the number (2) indicating the required stitch length in mm is opposite the screw (3).
7.9 Backtacking (reverse feed; closing up) 2 1 Backtacking with a hand lever(applies to manually controlled subclasses) – Press the lever (1) downwards. The machine will feed in the reverse direction until you release the lever. Backtacking with a microswitch (applies to automatically controlled subclasses) – Press the microswitch (2). The machine will backtack until you release the grip.
7.10 Setting of zig-zag stitch width (throw) and position C 3 2 1 A GB Attention! At setting the zig-zag stitch width (throw) and position the needle must not be inside the sewn material. There is a threat of the needle breaking! Setting of zig-zag stitch width – Press the lever (1) in the arrow direction (A) until it strikes the lever (2) - the lever arrest is released (2).
7.11 Starting up of manually controlled machine with clutch motor 2 1 3 – – – – 22 Start up the motor (1) with the switch (2) - the drive motor is running continuously. Tread the pedal (3). The drive friction clutch switches in this way and the sewing machine starts running. Regulate the sewing speed by pressure on the pedal (3). The friction clutch slip changes and thus also the machine speed changes in dependency on the pressure. Release the pedal(3). The sewing machine will stop.
7.12 Control of machine equipped with positioning motor and solenoid automatic control 7.12.1 Control pedal -2 -1 0 1 2 13 The pedal position is scanned with a proximity switch which distinguishes 16 levels.
7.12.2 Key control panel 2 1 Key 24 Function 1 Hand backtacking When the key is pressed at sewing, the sewn material is fed backwards.
8. Efka DC1550/DA321G positioning motor GB DA321G control contains all needed control elements for a function switchover and parameter setting.The operation is possible without the control panel, the sewing programming is not enabled. To the machine control also control panels V810 and V820 can be connected which are available as an attachment. By means of V820 control panel it is possible to program the sewing.
9. 9.1 Sewing with machine equipped with positioning motor Machine automatic functions The machine has functions stated below which are automatically carried out during the seam sewing dependent on: – pre-selection – pedal position (according to the machine operator s selection) – work phase of seam sewing Automatic function Pre-selection Needle positioning • needle down at machine seam-stop • needle up at machine seam-stop Note: After the seam finishing* the machine always stops with the needle up.
The automatic function pre-selections are described in the drive manufacturer s accompanying Instruction for Use. For Efka DA321G motor also see the drive manufacturer s Instruction for Use on website www.efka.net. Certain automatic functions can be pre-selected by means of keys. Their description is included in the publication Efka Instructions for Use, sections 4, 12, 13. Further automatic functions can be pre-selected through the drive parameter change. Every such function has its parameter number.
10. Maintenace 10.1 Cleaning and checking Attention! Danger of injury! Maintenance may be carried out only when the machine is switched off and the motor stopped! Attention! Maintenance must be carried out in prescribed intervals. Neglection of maintenance may result in malfunction requiring costly repair. 3 1 5 Mainenance operation 2 4 Maintenance interval Throat plate (1) disassembly.
