Needle and Thread Setting the needle Use only System 705 needles. Needles with blunt points or bent needles should never be used. Turn handwheel towards you until the needle bar is at its highest. Hold needle between thumb and forefinger of the left hand, so that the long groove faces non! The flattened end of the needle shank must therefore be at the rear. Now loosen the needle holder screw by turning it in anticlockwise direction and insert needle until it strikes above. Then tighten needle holder screw by turning it to the right. It is important that the needle should be pushed right up to the needle stop and be firmly clamped by the needle holder screw. Correct needle and thread selection System 705 needles should be used exclusively on the BERNINA-Record, Model 730, 731 and 732. In order to obtain satisfactory results, use only these first class needles, as also highgrade thread. First select the thread suitable for the intended work, and then the needle to accommodate the thread, using tothisintent the table on the oppositepage as a guide. The relation between needle and thread is correct if the thread, when placed in the long needle groove, fills this latter well and can be freely moved to and fro. For sewing the usual needle sizes are no. 80, 90 and 100 whereas for darning use needles of the sizes no. 70 and 80.
