3. HOW TO WIND THE BOBBINS
1
Put bobbin into the thread winder
shaft until it will go no further.
2
Pass thread through thread guide
plate
8
, open thread tension disk
7
and put the thread into the slit of
thread tension rod
4
.
3
Pass thread in the order as
shown in the figure, and wind the
thread onto bobbin by four or five
turns. (The direction of the arrow
corresponds to the direction of
rotation of the bobbin.)
4
Press bobbin thread guide
1
and
the bobbin rotates.
5
The thread winder will automatically
stop as soon as it has wound up
the bobbin to a predetermined
amount.
1. If you want to wind a bobbin, start winding it from recess
5
as illustrated in the figure above. If
you start to wind a bobbin from portion
6
, the detection of run-out of bobbin thread will fail to
be performed normally.
2. To ensure the appropriate remaining amount of bobbin thread, it is important to wind the bobbin
uniformly. Be sure to check that the bobbin is uniformly wound particularly at the start of
bobbin winding.
If the bobbin fails to be uniformly wound with thread, properly adjust the lateral position of
tension post socket
3
.
3. It is most suitable to wind the bobbin with thread to approximately 80% of the outer diameter of
the bobbin. The winding amount can be adjusted with winding amount adjustment screw
2
.
4. Do not press lever
1
except when winding bobbin thread. Motor continues to run and trouble
will be caused.
5. When abnormalities such as overload of the thread winding motor, etc. are delected, thermal
switch
9
is shut off. When thermal switch is shut off, turn ON thermal switch
9
again after
turning OFF it to return.
