(1) Adjust the timing between the needle and the hook as follow:
1) Turn the handwheel to bring the needle bar down to the lowest point of its stroke,and loossen
sntscrew.
* Adjusting the needle bar height
2) Pull the needle bar,you can see the pinhle basset 1/2 level through edge of inside hook(needle must
be position). Turn needle cover wire slot left,then tighten setscrew.
* Adjusting position a of the hook
3) First move the point of hook in direction, when running strap pulley needle bar risen from the
lowerst,Observe cooperate relation of the hook and needle.When hook point above Pinhole about
top of 1mm to 1.5mm and when plane of the hook point form plane of needle short bar 0.05mm(keep
the align hook blade point with the center of needle),tighten the hook setscrews.
(1)How to operate
1)The moment switch buttom
is pressed,the mahine performs reverse feed stitching.
2)The machine performs reverse feed stitching as long as the switch lever is held depressed.
3)The machine resumes normal feed stitching the moment the switch leveris released.

(1)Changing the stroke of thread take-up spring
1) Loosen setscrew
.
2)As you turn tension post
clockwise (in direction A),the stroke of thread take-up spring will
be increased.
3)As you turn the knob counterclockwise (in direction B),the stroke will be decreased.
(2)Changing the pressure of thresd take-up spring
1)Loosen setscrew
,and take out tension asm
.
2)Loosen setscrew
,and remove tension post
..
3)As you turn tension post
clockwise(in direction A),the pressure will be increased.
4)As you turn the post counterclockwise(in direction B),the pressure will be decreased.
注意
若间隙太小，会磨损梭尖，若间隙太大，则会引起跳针；
旋梭原来用的什么型号，调换后，也请使用原来的型号；
更换机针后注意机针必须安装到位且类型相同，如不同类型机针须检查配合关系。
*Precaution
If the clearance is too small,the tip of the hook will be abraded.
If it is too big,it will lead to skip over.
*Note that the type of hook to be substiuted for,when peplacing the hook.Shall be in
conformity with the very type of the hook installed in the sewing machine of original
assemblge.
After replacing the needle.the needle must be same type and install right pisition.If the
needle is different type need check match with relation.

）面线张力的调节：
1
）根据不同的缝制条件，用螺母
来调整面线张力。
2
）若把螺母
按顺时针方向（即
A
方向）转动时，面
线张力将增大。
3
）若把螺母
按逆时针方向（即
B
方向）转动时，面
线张力将减小。
（
2
）底线张力的调节：
1
）将夹线螺钉
朝顺时针方向（即
C
方向）转动时，
底线张力将增大。
2
）将夹线螺钉
按逆时针方向（即
D
方向）转动时，
面线张力将减小。
(1)Adjusting the needle thread tension
1)Adjust the needle thread tension using tension ad just nut
according to the sewing specifications.
2)As you turn nut
clockwise(in direction A),the needle thread tension will increase.
3) As you turn nut
counterclockwise(in direction B),the tension will decrease.
(2)Adjusting the bobbin thread tension
1) As you turn tension adjust screw
clockwise(indirection C),the bobbin thread tension will
increase.
2)As you rurn screw
counterclockwise(in direcrion D),the bobbin thread tension will decrease.
