Attachment of Lift lever and Adjusting plate assy
1. Insert the presser lift lever shaft into the lift lever holder assy, spring torsion (XE4040), lift lever and lift
lever holder assy, then attach the retaining ring E4 to the presser lift lever shaft. Attach the lift lever
holder assy to the upper unit holder assy with the screw (taptite, bind B M4x10) while pulling up the lift
lever.
*Key point
• Be sure to hang both ends of spring on the lift lever holder assy and lift lever.
• Make sure that the presser bar clamp assy is on the upper side of lift lever.
2. Set the spring (XC9435) to the tension release switch lever, and set it to the shaft of adjusting plate
assy, then attach the retaining ring E3. Hang the tip end “A” of spring (XC9435) on the tension release
switch lever, and hang the tip end “B” of spring (XC9435) on the adjusting plate assy. Pass the lift lever
through the hole of adjusting plate assy, and attach the adjusting plate assy to the upper unit holder
assy with the two screws (taptite, bind B M4x10).
3. Set the spring (XG0403) to the adjusting plate assy and the W presser adjust plate.
*Key point
• If the spring is attached in wrong direction, the spring interferes with the embroidery foot when it is attached,
resulting in spring coming off. Refer to the illustration below to attach the spring in correct direction.
