4-3. Needle size and gauge
When changing the needle size, it is necessary to adjust the hook and to replace the gauge.
(1) Adjustment
In the standard delivery state, the hook has been factory-adjusted to DP × 5 #14 needle for the S
type and to DP × 17 #18 needle for the H type.
When changing the thickness of the needle, perform the adjustment of
dle-to-shuttle relation" p.115
When changing the length of the needle, perform the adjustment of
"III-1-1. Adjusting the height of
the needle bar (Changing the length of the needle)" p.115
When the adjustment of hook and driver is not fit to the thickness of the needle, sewing trou
-
bles such as stitch skipping and the like or abrasion of the blade point of hook will be caused.
(2) Gauge
When changing the needle size, replace the gauge with the optional gauge of the correspondence table.
*1 There is a case where the sewing quality is increased by changing the gauge to other gauge in accordance with the sewing conditions.
Example 1 :
When stitch skipping occurs with the needle #14, change the intermediate presser from 14103352 to 14103253.
Example 2 : When stitches are not well tightened with the needle #19, change the intermediate presser from 40023632 to
B1601210D0BA.
1. The table above describes the typical optional gauges.
For the other special gauges, ask our sales distributors.
2. When using the gauge that is not fit for the thickness of the needle, needle breakage,
abrasion of components such as inner hook and the like, sewing trouble such as stitch
skipping and the like will be caused.
Example : When sewing the sports shoes with a big size needle guide or inner hook
presser, needle thread loop becomes unstable and stitch skipping or thread
breakage may occur.
