5-2. Needle thread clamp device
By actuating the needle thread clamp device, trouble of sewing at the high-speed start (needle thread
slip-off, stitch skipping or needle thread stain) is prevented, and can reduce gathering (bird's nest) of
needle thread on the wrong side of cloth while keeping stable sewing. Needle thread clamp device
operates in the state that thread clamp display LED is lit, and does not operate when it goes off.
Operation ON/OFF is changed over using
button. When the needle thread clamp device is OFF,
the machine automatically operates at slow-start.
When memory switch No. 35 is "1" (prohibited), the thread clamp does not work. In addi-
tion,
button is ineffective.
* Matters that demand special attention when using the needle thread clamp device
For the thread clamp unit, there are S type and H type in accordance with the sewing types. Refer the

1. When using the area 1510 with the standard method, the use of 3P pedal is the same as
that of 2P pedal. Refer to [In case of 2P pedal].
When using the pedal as 3P pedal by remodeling the presser or the like, it is necessary
to change the connecting procedure of the pedal and memory switches U81 and U82.
2. When the 2-step stroke function is used, the feeding frame can be stopped at an arbi-
trary intermediate position.
To use the 2-step stroke function, it is necessary to change the setting of the relevant
MEMORY switch. Refer to
