● Turn handwheel until the needle bar is approx. in the required position.
● Insert the adjustment pin 1 into the hole.

Setting the needle bar position 0.6 mm below TDC (feed motion timing):
● Fit adjustment gauge 3 onto bolts 4 and 5, ensuring that the right side (for 32 or 36 mm
needle bar stroke) is used.
