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).
