(j] Adjusting knife and fixed knife
1. Attaching fixed knife
1) Attach the fixed knife so that the attached part parallels the rotary hook base. The movable knife
broadens
at part®. Make sure the fixed knife doesn't contact it at this part.
2. Knife timing
1) While pushing the cam lever 0 up with a finger, rotate the pulley @ in the direction of the arrow.
When
the knife @) begins to move, the pulley will become harder to turn. At this time, tighten the screw
of the 24 J gear e I fix the cam CD by hand so it does not rotate, and turn the pulley. The rotary hook
blade should be in the center of the rotary hook supporter@).
2) Tighten the screw of the 24 J gear e so there is no backlash of the cam in the direction of the lower
shaft. While pushing the cam lever 0 up with a finger, rotate the pulley @again. When the knife @)
begins to move, the blade in the rotary hook should be in the center of the rotary hook supporter @).
3. Knife position
Loosen the screw & and adjust the knife @) position so that its end projects 1 mm beyond the fixed
knife's tip.
After thread trimming, the knife should be in this position.
If the knife does not stop at the stop position, the upper shaft will be locked and it cannot make one full
revolution. In that case, move the knife to the stop position by hand.
4. Knife and fixed knife
1) With a marker, color the back of the knife @) and engage it with the fixed knife @) manually. Check that
the colored portion is shaved equally. This shows proper knife engagement.
2) If the engagement is wrong, loosen the screw @) of the fixed knife @) and adjust the inclination with the
lower set screw CD).
NOTE: The inclination of the fixed knife @)should be adjusted with the two top screws @) and the
bottom set screw CD).
NOTE: This is fine adjustment. Adjust carefully.
