9-9. Adjusting the wiper

1. When the thread wiper solenoid plunger (1) is driven to the full stroke, the wiper (2) should be 15 mm in front of the

needle center.    Loosen screws (3) and shift the entire solenoid bracket (4)up or down to adjust.
The standard height from the solenoid bracket (4) bottom to the needle plate top is approximately 112 mm.

2. When the wiper (2) is operated and aligned with the center of the needle bar, the distance from the wiper (2) to needle

tip should be approximately 2 mm. Loosen screw (5) and move the wiper (2) in or out to adjust. As shown in Fig. A,
make sure the wiper (2) does not strike the presser foot (6) or needle.

Note

Check that the wiper (2) is not touching the finger guard.

9-10.  Adjusting the needle up stop position

• The needle up stop position has been adjusted so that

the tip of the needle stops 17.5 – 19.5 mm above the
top of the needle plate.

• If adjustment is necessary, loosen the screw (2) at the

"U" mark of the machine pulley (1) and adjust the
position of the machine pulley (1). The machine pulley
(1) stops later if it is turned clockwise, and it stops
earlier if it is turned counterclockwise.

Note

• The screw (3) is used by the needle down

detection function and should not be loosened.

• The screw (4) is a screw for detecting the machine

top position, and should not be loosened.

• If the index mark is not inside the mark when be

displayed (when memory switch No.14 is on). Turn
the machine pulley to move the index mark to the
correct position and then start the sewing machine.
