ADJUSTMENT
Wa r n i n g :
When the machine is used for long time, the stitch density can be changed because of the
running of the main cam brake and main shaft brake. That is why it is necessary to adjust the brakes.
A d j u s t i n g m a i n c a m b r a k e
The main cam brake controls the density of stitches which is adjust in chapter 2. It is a producer specifica-
tion for setting the distance between stitches. Under normal use, the brake band will need to be adjusted
again. The reason is to run in the brake band:
1.
Loosen the locking nuts .
2.
By rotating the nuts is moving the brake band
(in direction
4
to increase the break pressure,
move the brake band in direction
3
to decrease the pressure).
3.
Tighten the locking nuts .
C A U T I O N !
If the main cam brake pressure is excessively high, the machine may malfunction. The
brake pressure is used for easy breaking of the main cam brake, so that the main cam brake is not moving
itself by rotary inertia.
H E L P :
Adjust the stitch density according to the chapter 2 to require density with loosen the brake. Then
lightly pull the brake, so that the number of stitches increase maximally to one stitch of length of the button-
hole. This will ensure correct function of the brake.
