1. Loosen the screw t (at the U side on the pulley q), and turn the pulley q so that the mark w on the pulley is inside the
mark r of the belt cover e .
The pulley q stops later if it is turned clockwise; it stops earlier if it is turned counterclockwise.
The standerd needle up stop position is 6 mm below the needle bar dead point.
2. Timing between the needle and the feed mechanism is adjusted so that the feed mechanism srarts operating after the
needle comes out of the material sewn, and stops before the needle penetrates the material.
The screw y on the D side is tightened fully counterclockwise at the time of shipment.
3. The screw u cannot be adjusted because it is used for detecting the needle stop position.
