6 6.1 Operation Threading the needle thread Caution: danger of injury ! Turn off the main switch. The needle thread may only be threaded with the sewing machine switched off. – – – – – – – – Put the thread reel on the thread stand and lead the needle thread through the unwinder arm. The unwinder arm must be in vertical position above the thread reels. Thread in the thread through threading guide 1 and 2. Conduct the thread clockwise around the pre-tensioner wheel 3.
3 14 2 1 5 4 Fig. A: Correct thread interlacing in the center of the material Fig. B: Needle-thread tension too low or hook-thread tension too high Fig.
6.2 Adjusting the needle-thread tension Pre-tensioner When the main tensioner 2 and supplementary tensioner 3 are open (e.g. when the sewing feet are raised) the needle thread must be under slight residual tension. This residual tension is produced by the pre-tensioner 1. The pre-tensioner 1 simultaneously affects the length of the end of the severed needle thread (the starting thread for the next seam). – Basic setting: Turn knurled nut 4 until its front is flush with the bolt 5.
6.2.1 Function of the thread main tension and the thread supplementary tension in relation to the sewing foot lifting Only Efka DC 1550 DA 321G The thread supplementary tension can, at any time, be switched on or off by actuating the switch key 1 (see chapter 6.17) on the key block of the machine. To this end, the parameter F-255 must be set on “7". Parameter Sewing foot lifting Sewing foot lifting withing a seam after thread trimming Thread main tension Thread supplement.
6.2.3 Function of the thread’s supplementary tension in relation to the stroke adjustment and the Speedomat Only Efka DC 1550 DA 321G The thread’s supplementary tension can, at any time, be switched on and off by actuating the key 1 (see chapter 6.17) of the machine’s keypad. To that end, the parameter F-255 must be set to “7". Parameter Setting F-197 F-197 F-197 F-197 = = = = stroke adjustment max.
6.4 Short stitch The short stitch can be set mechanically forward as well as backward. The short stitch is set by turning the stop screw 2 with an Allen wrench (size 3): Clockwise à forward. Counterclockwise à backward. 6.4.1 Short stitch at the seam beginning When sewing without initial bartack the reliability of the seam beginning can be increased by beginning the seam with a short stitch.
6.5 Switching the supplementary tension on and off with machines without thread trimmer 1 2 The supplementary tension is being switched on and off with lever 1. Switching on – Push the handle 2 of lever 1 to the left. Switching off – Push the handle 2 of the lever 1 to the right.
6.6 Adjusting the thread regulator 3 2 1 Caution: danger of injury ! Turn off the main switch. The thread regulator may only be adjusted with the sewing machine switched off. The thread regulator 1 controls the quantity of needle thread required for stitch formation. The thread regulator must be precisely adjusted for an optimum result. At the correct setting the needle-thread loop must slide at low tension over the thickest point of the hook. – Undo screw 2. – Adjust the thread regulator 1.
6.7 Winding on the hook thread 5 4 3 2 – – – – – – – – 1 2 6 Put the thread reel on the thread stand and conduct the needle thread through the unwinder arm. Conduct the thread through the thread guide 5, around the tensioner 4 and through the thread guide 3. Place the thread behind the blade 6 and sever it (in the arrow direction). Fit the bobbin 1 onto the bobbin winder. There is no need to wind the thread onto the bobbin by hand. Press the bobbin-winder lever 2 into the bobbin.
6.8 Changing the hook-thread bobbin 1 7 6 5 4 3 2 Caution: danger of injury ! Turn off the main switch. The hook-thread bobbin may only be changed with the machine switched off. Removing the empty bobbin – Raise the sewing foot. – Pull the hook cover 1 upwards and open it. – Lift the flap 5 and remove the empty bobbin 2. Inserting a full bobbin – Insert the full bobbin 2 so that it moves in the opposite direction of the hook when unwinding.
6.9 Setting the hook thread tension 1 2 Caution: danger of injury ! Turn off the main switch. The hook-thread tension may only be adjusted with the machine switched off. Setting the tension spring 2 – Set the tension spring 2 by turning the adjustment screw 1.
6.10 Inserting and changing the needle with single-needle machines 1 2 3 2 1 Caution: danger of injury ! Turn off the main switch. The needle may only be changed with the sewing machine switched off. – Turn the hand wheel, until the needle bar 1 has reached its highest position. – Loosen screw 2. – Pull the needle downwards out of the needle bar 1. – Push in the new needle into the hole of the needle bar 1 as far as it will go. Attention! The needle scarf 3 must point towards the hook.
6.11 Inserting and changing the needle with double-needle machines 1 2 3 4 Caution: danger of injury ! Turn off the main switch. The needle may only be changed with the sewing machine switched off. – Turn the hand wheel until the needle bar 1 has reached its highest position. – Loosen screw 3. – Pull the needle downwards out of the needle holder 2. – Push the new needle into the hole of the needle holder 2 as far as it will go.
6.12 Lifting the sewing foot 2 1 Subclasses 868-190020, 868-290020 The sewing feet can be lifted mechanically by actuating the knee lever 1. Subclasses 868-190322, 868-290322, 868-390322 The sewing feet can be lifted electro-pneumatically by actuating the pedal 2 or the knee lever 1. Raising the sewing foot mechanically (knee lever) – To adjust the position of the material (e.g. for corrective purposes), push the knee lever 1 to the right.
6.13 Locking the sewing feet in lifted position 1 1 – Push the lever 1 downwards. The sewing feet are locked in lifted position. – Push the lever 1 upward. The sewing feet’s position is unlocked. 2 Or – Lift the sewing feet pneumatically by pushing the knee switch. The lever 1 then moves back into its initial position. 6.14 Sewing-foot pressure The required sewing-foot pressure is set with the setting wheel 2. CAUTION ! The material must not ”swim”. Do not set a higher pressure than is necessary.
6.15 Sewing-foot stroke 2 1 3 The special sewing machine 868 has, depending on the subclass, as standard equipment two setting wheels for the sewing foot stroke. With the left setting wheel 2 the standard sewing foot stroke from 1 to 9 mm is selected. With the right setting wheel 1 an increased sewing foot stroke from 1 to 9 mm is selected.
Operation mode of the quick stroke adjustment The activation period of the maximum sewing foot stroke depends on the set operation mode. It is possible to choose between three operation modes. The individual operation modes are determined by the adjustment of the parameters F-138 and F-184 at the control panel (see enclosed instructions of the motor manufacturer).
6.16 Setting the stitch length 3 2 1 The special sewing machines 868 are, depending on the subclass, equipped with two setting wheels. Thus, two different stitch lengths can be sewn, that are activated by actuating a key (see chapter 6.17). The two stitch lengths are set with the setting wheels 1 and 2 on the machine arm. – Set the higher stitch length with the upper setting wheel 1. Setting 1 = min. stitch length Setting 12 = max.
6.17 Key pad on the machine arm 10 9 8 Key 7 6 5 4 3 2 1 Function 1 Supplementary thread tension If the key is lit up: Supplementary thread tension is switched on. If the key is not lit up: Supplementary thread tension is switched off. 2 2 stitch length If the key is lit up: Higher stitch length (upper setting wheel) is active If the key is not lit up: Smaller stitch length (lower setting wheel) is active 3 Recalling or suppressing the initial or final bartack.
LED Function 7 and 8 Display for empty bobbin with residual thread monitor (left/ right bobbin) 10 LED display “power on" The function of key 9 can be selected with the screw 6 underneath the key 5. – Select a function. Example: 5 = Manually sewing backward. – Turn in the screw 6 underneath the key 5 and turn it 90° to the right (the slot stands vertically). The function can now be called via both keys 5 and 9.
