Disengagement Of Cam Follower - Janome JF1018S Servicing Manual

DISENGAGEMENT OF CAM FOLLOWER

Correct setting
Too narrow clearance between the cam follower and the top convex of zigzag cam may
often cause difficulty in turning of the pattern selector dial, selecting a correct pattern or
zigzaging in straight stitch setting.
To adjust
1. Remove the front cover. (See page 4.)
2. Attach the pattern selector dial, and set it at pattern "B". (5th cam as viewed from "C".)
3. Turn the balance wheel to put the cam follower onto the top convex of the zigzag cam.
4. Loosen the set screw.
5. Push the convex part of the cam follower releasing arm in the direction of arrow until
the cam follower releasing arm touches to position (A) of the pattern select cam, then,
tighten the set screw.
Note: After this adjustment, check that the clearance between the zigzag cam and the
cam follower is 0.3mm when the cam follower releasing arm has removed to
position (B) by turning the pattern selector dial counterclockwise, and also the
clearance between the cam follower and the zigzag cam should be 0.3mm.
6. Remove the pattern selector dial, and attach the front cover.
