1. Description of product 1.1 Description of proper use The 1225/5 is a sewing unit which can properly be used for sewing light to medium-weight material. Such material is, as a rule, made of textile fibres. These materials are used in the garment industry. In general only dry material should be sewn on this machine. The material must not contain any hard objects. The seam is generally made with core thread, polyester fibre or cotton threads.
– – – – – Vertical cutter with suction for overlocking and serging in one operation Chain separator with suction, programmable Adjustable blowing nozzles in the table top for supporting the material feed Height-adjustable stand, infinitely variable from 850 mm to 1200 mm Integrated stacking device 1.
2. Optional equipment See annex 3. Switching on - Switching off - Program stop 1 1 3.1 Switching on – Switch on main switch 1 (turn in clockwise direction). The control loads the machine program. The basic display appears in the display of the control panel. – Switch off main switch 1 (turn counter-clockwise). 3.
3.3 Program stop 2 2 1 For an immediate stop in case of operating errors, needle breakage etc. the safety system of the 1225/5 provides the following measures: – Press program stop switch 2 at the control panel. The running operations are stopped immediately. – Turn main switch 1 counter-clockwise. The sewing unit drops out immediately; all movements of the sewing unit stop immediately. 3.4 Restart after program stop Caution: Risk of injury! Switch the main switch off.
4. Operation of the sewing machine head 4.1 General notes 1 The operation of the sewing machine head (needle insertion, threading of needle thread and hook thread etc.) is described in the attached separate Pegasus operating instructions. The instruction manual is included in the accessories of the sewing unit. Attention: Risk of injury! Please read the operating instructions of the sewing machine head carefully and observe all notes on safety.
4.2 Recommended threads Needle system: Recommended needle size: B27 Nm 80 for very thin material Nm 90 for thin material Nm 100 for medium-weight material High sewing security and good sewability are achieved with the following core threads: – Two-ply polyester endless polyester core-spun (e.g. Epic Poly-Poly, Rasant x, Saba C, ...) – Two-ply polyester endless cotton core-spun (e.g. Frikka, Koban, Rasant, ...
