[Adjusting the counter knife]
1) Properly installing the knife thread guide
Install the knife thread guide ❶ so that the needle enters exactly the center of its opening.
2) Properly installing the counter knife
1. The standard distance from the blade point of the counter knife ❷ to the knife thread guide ❶ , which is posi-
tioned so that the needle enters the center of its opening, is 0.5 mm.
2. The blade point of the counter knife ❷ is about 4 mm away from the center of the needle.
3. The sharpness of the counter knife ❷ depends upon the installing angle of the blade point of the counter
knife ❷ . The proper overlap of the counter knife ❷ blade with that of the moving knife ❸ will provide the best
sharpness.
4. Whenever the counter knife ❷ has been readjusted or replaced, be sure to check the sharpness of the count-
er knife ❷ , and adjust the installing angle of the counter knife ❷ .
