4995Q

Turn the machine pulley to align the tip of the rotary hook with the center of the needle, and then loosen the set screw (1) and turn the eccentric shaft (2) to adjust so that the clearance between the needle and the rotary hook is 0.01 0.08 mm.

7-7. Adjusting the shuttle race thread guide

3574Q

Install the shuttle race thread guide (1) by pushing it in the direction of the arrow so that the needle groove is aligned with the center of the needle plate hole.

NOTE:

If the shuttle race thread guide is in the wrong position, thread breakages, soiled thread or tangling of the thread may occur.

The position of the shuttle race thread guide is adjusted at the time of shipment from the factory. It should not be changed if possible.

7-8. Rotary hook lubrication amount

More oil

Less oil

The optimum position is when the head of the set screw (1) is aligned with the edge of the bed. The rotary hook lubrication amount can be adjusted within three turns to the right from that position.

If the set screw (1) is turned clockwise, the lubrication amount becomes smaller.

If the set screw (1) is turned counterclockwise, the lubrication amount becomes greater.
