3 Operation 3.1 Threading the needle thread Caution: Risk of injury! Switch off the main switch! The needle thread should only be threaded when the sewing machine is switched off. 1 12 2 11 3 10 4 9 5 8 6 7 Fig. 1 Fig. 2 – Place the thread reel on the thread stand and guide the needle thread through the unwinder arm. – The unwinder arm must be in a vertical position above the thread reels. – Thread in the thread through threading guides 1 and 2.
3.2 Adjusting the needle-thread tension 1 4 5 3 2 Fig. 3 Fig. 4 Fig. a: Correct thread interlacing in the centre of the material Fig. b: Needle-thread tension too strongorhook-thread tension too weak Fig.
Pre-tension When the main tensioner 2 and supplementary tensioner 3 are open 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 adjusting knob 4 until its front is flush with bolt 5. Shorter starting thread: – Turn adjusting knob 4 clockwise.
3.2.2 Function of supplementary thread tension in relation to the sewing foot lift and the Speedomat for subclass 667-180312 and 667-180332 Button 1 (see chapter 3.15) on the machine's keypad can be used to activate or deactivate the supplementary thread tension at any time. Parameter F-255 must be set to "7" for this to work. Parameter Adjustment F-197 = 0 F-197 = 1 F-197 = 2 F-197 = 3 Max.
3.3 Opening the thread tension Subclasses 667-180010, 667-180030 When lifting the sewing feet with the knee switch, main and supplementary tension are automatically opened. Subclasses 667-180112, 667-180132, 667-180312, 667-180332 The thread tension is automatically opened when trimming the thread. 3.4 Turning the supplementary thread tension on and off for subclasses 667-180312 and 667-180332 1 2 Fig. 5 The supplementary tension can be switched on and off with lever 1.
3.5 Adjusting the thread regulator 1 3 2 Fig. 6 Caution: Risk of injury! Switch 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. With correct setting the needle-thread loop must slide with low tension over the thickest point of the hook. – Loosen screw 2.
3.6 Winding on the hook thread 5 6 4 1 3 Fig. 7 2 2 Fig. 8 – Put the thread reel on the thread stand and lead the hook thread through the unwinder arm. – Pull the thread through guide 5, tensioner 3 and guide 4. – Place the thread behind the blade 6 and sever it. – Insert 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. – Start sewing.
3.7 Changing the hook-thread bobbin 1 2 Fig. 9 Caution: Risk of injury! Switch off the main switch.

Insert a full bobbin. – Insert a full bobbin into the bobbin case 3. 6 5 4 3 – Observe the direction of rotation of the bobbin.
3.8 Setting the hook thread tension 1 4 3 2 Fig. 10 Caution: Risk of injury! Switch off the main switch. The hook-thread tension may only be adjusted with the sewing machine switched off. Brake spring The brake spring 1 is responsible for preventing a bobbin overrun when the machine stops and when the hook thread is being cut. It cannot be adjusted! Setting the tension spring – Adjust the tension spring 4 with the adjustment screw 3. Turn until the required tension force is present.
3.9 Changing the needle 3 2 1 2 Fig. 11 3 Fig. 12 Caution: Risk of injury! Switch off the main switch. The needle may only be changed with the sewing machine switched off. – Turn the handwheel until the needle bar 1 reaches its highest position. – Loosen screw 2. – Pull the needle downwards out of the needle bar 1. – Insert the new needle into the hole of the needle bar 1 and push it until it stops.

The sewing feet are unlocked. or – Lift the sewing feet pneumatically or by using the knee lever. The lever 1 then swivels back to its starting position. 3.12 Sewing foot pressure The required sewing foot pressure is adjusted with rotary knob 2. CAUTION! The material should not "float".
3.13 Sewing-foot stroke 2 Fig. 16 1 3 Fig. 17 Depending on the subclass, the 667 special sewing machine is equipped with two adjusting knobs as standard for adjusting the sewing-foot stroke. Use the left adjusting knob 2 to select the standard sewing-foot stroke between 1 and 9 mm. Use the right adjusting knob 1 to set a higher sewing-foot stroke between 1 and 9 mm.
Operating mode for rapid stroke adjustment The activation time for the maximum sewing-foot stroke depends on which operating mode is set. You can select between three different operating modes. The individual operating modes are determined by the setting of parameters F-138 and F-184 on the operating panel (see enclosed instructions from the motor manufacturer).
3.14 Adjusting the stitch length 1 3 1 Fig. 19 2 Fig. 20 Depending on the subclass, the 667 special sewing machines are equipped with two adjusting knobs. These allow two different stitch lengths to be used when sewing, which can be selected by using button 4 (see chapter 3.15). The two adjusting knobs 1 and 2 on the machine arm are used to adjust the stitch lengths. – Adjust the longer stitch length with the upper adjusting knob 1. Position 1 = min. stitch length Position 9 = max.
