[ Warning ]
Before adjustments, always turn off the motor switch and check to make sure that the motor is in stop mode.
After all adjustments are made, place the thread properly
and check the followings before starting sewing.
The moving mes① should pass by the inner side of
the loopers③, ④. And the tip of the looper hook②
should pass in front of the looper thread.
When the moving mes① returns, the needle thread
and the looper thread should be caught by the hooks
②, ⑤ respectively. And the threads should be cut by
the fixed mes.
If the moving mes doesn’t operate properly, adjust
the distance between the left needle and the tip of the
needle thread hook at over 2.5~3.0mm (See [Fig. 76]
Adjustment of Moving Mes and Needle.)
