E - MACHINE ADJUSTMENT FOR THE ROUND EYE
4. ROUND EYE MACHINE EYELET DIAMETER OF CUTTING SPACE
CHANGE
To alter the eyelet diameter, without affecting the stitch bite, loosen the locking screw  and rotate the
eccentric adjusting screw  to the left 1 or right 2, as needed. Rotating left, decreases the diameter,
rotating right increases the diameter.
CAUTION! If a significant eyelet diameter change is performed, ensure the cutting knife and cutting
block are correct. Check the looper / spreader adjustment and reset if needed. Before sewing large
diameter buttonholes, manually rotate the handwheel to ensure the needle is not contacting the throat plate.
By every machine is mentioned, what is the biggest possible diameter of the buttonhole which can be sewn
on the machine if is not performed the change of standardly supplied round foot configuration.
5. CLAMP FEET USING FOR CORRECT BUTTONHOLE SEWING
The machine is equipped by the special round feet. The figure ex-
plains principle and construction of these feet.
For sewing bigger diameter buttonholes is necessary to use another
size of foot and cutting steel. The rule is so that external sewn diam-
eter of the buttonhole D was at least 2 mm smaller then external
diameter of the foot. Combination suitable feet and plates for thin or
thick materials with standard bite size 2,4 mm (0.094”) is mentioned
in table below.
