6. Operation 6.1 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. – – Place the yarn reels on the reel stand and pass the needle and looper threads through the unwinding arms. Unwinding arm 1 must be vertically above the yarn reels. Thread the needle thread as shown in the following illustration.
5 1 10 4 3 Fig. A: Correct thread loop in the centre of the material Fig. B: Needle-thread tension too low or Looper-thread tension too high Fig.
6.2 Adjusting the needle-thread tension Pre-tensioner When the main tensioner 4 and supplementary tensioner 5 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 2. The pre-tensioner 2 simultaneously affects the length of the end of the severed needle thread (the starting thread for the next seam). – Basic setting: Turn knurled nut 2 until its front is flush with the bolt 1.
6.4 Adjusting the thread regulator 4 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 3 controls the quantity of needle thread required for stitch formation. The thread regulator must be precisely adjusted for an optimum result. The thread-regulator setting depends on the following factors: – Stitch length – Material thickness – Characteristics of the sewing yarn in use.
6.5 Winding on the looper thread 4 3 2 – – – – – – – 1 5 Pull the thread through the guide 3 and the tensioner 4. Place the thread behind the blade 5 and sever it. Fit the bobbin 1 onto the bobbin winder. Hint There is no need to wind the thread onto the bobbin by hand. Press the bobbin-winder lever 2 into the bobbin. Sewing The bobbin-winder lever terminates the process as soon as the bobbin is full.
6.6 Changing the looper-thread bobbin 5 6 1 2 4 3 1 Caution: danger of injury Turn off the main switch. The looper-thread bobbin may only be changed with the machine switched off. Removing the empty bobbin – Raise the needle bar. – Lift the bobbin-housing flap 1. – Extract the upper part of the bobbin housing 2 together with the bobbin 6. – Remove the empty bobbin from the upper part of the bobbin housing 2. Inserting the full bobbin – Insert the full bobbin in the upper part of the bobbin housing 2.
6.7 Pre-setting the looper-thread tension 1 2 4 3 Caution: danger of injury Turn off the main switch. The looper-thread tension may only be adjusted with the machine switched off. Braking spring The braking spring 1 prevents the bobbin from running on when the machine halts and when the looper thread is severed and cannot be adjusted! Setting the tension spring – When the bobbin is full the top of the bobbin housing 2 should gradually descend under its own weight (see right-hand illustration).
6.8 Changing the needle 1 2 3 Caution: danger of injury Turn off the main switch. The needle may only be changed with the sewing machine switched off. – – – Undo screw 2. Push the new needle as far as it will go into the hole in the needle bar 1. CAUTION ! The throat 3 of the needle must face towards the shuttle tip. Tighten screw 2. CAUTION ! After changing to a needle of a different thickness the distance between the shuttle and the needle must be corrected (see servicing instructions).
6.9 Lifting the sewing foot 1 2 Subclass -170010; -180010 The sewing foot can be raised mechanically by operating the knee lever 1. Subclass -170115; -180115 The sewing foot can be raised electro-pneumatically by operating the foot 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 or press the pedal 2 half-way back.
6.10 Locking the sewing feet in the up position 2 1 Once they have been mechanically or pneumatically raised the sewing feet can be locked in the up position with button 1 (e.g. to wind on the looper thread). – With the machine at a standstill press the knee lever to the right or push the pedal half-way back. The sewing feet are raised. – Press button 1 and release the knee lever or pedal. The raised sewing feet are locked in the up position.
6.12 Setting the sewing-foot stroke 5 4 3 6 CAUTION ! Subclass -170010; -180010 has no automatic speed restriction. It is essential to reduce the speed when working with a large sewing-foot stroke (see the plaque on the sewing-foot-stroke lever). Excessive speed makes sewing noticeably noisy and causes damage to the machine. The required sewing-foot-stroke height is adjusted with the sewing-foot-stroke lever 5.
6.13 Setting the stitch length 3 2 1 4 Subclass -170010; -180010 The required forwards-stitch length is set with the knurled nut 1 in the manual stitch-setting lever 2. The required backwards-stitch length is set with the knurled nut 3 in the manual stitch-setting lever 2. Changing stitch length during sewing: The stitch length can be infinitely varied during sewing with the manual stitch-setting lever 2, within the limits of the stitch lengths set for forwards and backwards sewing.
