Turn handwheel slowly and observe the movement of needle. The blade of arc needle shall
be kept in line with the left needle guide groove and swing. Be sure not to touch the groove. (Pro-
cedure of adjusting the needle refer to the following relevant paragraph. ) Regulate the knob to its
orginal place, turn handwheel and observe the occurrence of the needle being crossing ridge form-
ing disc to avoid making the needle point mildewed. Make sure that all bent, blunt or mildewed
needles be replaced. Otherwise, it impaires the normal operational performance of the machine.

The right limit of needle depends (,n the limit of the needle throw. When the needle reaches
the right limit, the neeote-poim shall be in about 2mm distance from the right side of the needle
plate (Fig. 17). At this moment, the needle point is right put out of the limit point "E" of the
right needle guide groove(Fig. 17). If the positioning of location is incorrect, the limit of the nee-
die throw shall be regulated.
The regulating procedure is as follows:
Remove the upper arm cover, loosen lock screw "G" with screwdriver through the hole "H"'
on .the top of the upper arm.
Turn the eccentric ball shaft pin "F" with screwdriver to change the angle o( the needle shaft
throw. Thus make the limit of the needli: throw comply with the requirements (Fig. 18).
