Machine operation Needle threading Attention! Danger of injury! Thread when the main switch is switched off and motor stopped! – 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).
Hook thread winding – 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).
Bobbin fixing and hook threading Attention! Danger of injury! Switch the main switch off and wait for the motor stopping. – 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).
Thread tension adjustment 7.4.1 Needle thread tension adjustment 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).
7.4.2 Hook thread tension adjustment 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).
Needle replacement Attention! Danger of injury! Do the needle replacement when the main switch is switched off and motor stopped. – 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).
Foot lifting 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.
Foot pressure setting – 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.
Backtacking (reverse feed; closing up) 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) –...

7.11 Starting up of manually controlled machine with clutch motor – 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.
7.12 Control of machine equipped with positioning motor and solenoid automatic control 7.12.1 Control pedal The pedal position is scanned with a proximity switch which distinguishes 16 levels. The meaning is in the table: Pedal position Pedal motion Meaning Heel fully backwards Command for thread trimming (seam finish) Heel slightly backwards Command for foot lifting...
7.12.2 Key control panel Function Hand backtacking When the key is pressed at sewing, the sewn material is fed backwards. Needle positioning in upper or bottom position By the parameter F-242 (DA321) the key function can be defined: 1 = needle up/down 2 = needle up 3 = one stitch (factory setting is 1)
Efka DC1550/DA321G positioning motor 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.
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...
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.
