B448/BA15 BUTTON SEW THROUGH THE BUTTON HOLE
ADJUSTMENTS & OPERATING INSTRUCTIONS
1)Adjust the button loading arm S07075-001 so that the tips of the pins in the button catch plate are just clear of the underside of the button latch plate S09582-001.
2)Adjust the button clamp height to line up with the button movement arm S07075-001.
3)Turn the machine by hand to make sure the button alignment is correct and there is no fowling between the finger opening
cylinder and the button loading parts.
switch on the unit and press the reset switch, the reset switch must be pressed each time the unit is switched~n for the time.
The button clamp is lowered in two steps, to adjust step 1, set the step switch to position 3. Place the garment under the sewing clamp with the button hole central. Press the start switch ONCE to lower the clamp to position 1.
Adjust the height of the clamp assembly so that the tips of the button hole opening fingers are approximately 1mm above the button hole. This is done by the screw in the end of the cylinder (photo.B).
4) OPENING FINGER LENGTH.
The length of the button hole opening fingers must be adjusted for optimum results. They must be long enough to penetrate the thickness of the button hole to maintain a positive action.
However, if these are left too long this will create excessive button stand off. The best length is approximately 0.5mm longer than the thickness of the buttonholed fabric. These must be filed to the correct length and re-polished.
3 POSITION SWITCH.
POSITION 1. Is for standard sewing.
POSITION 2. Gives 2 step action.
First press of the start switch lowers the clamp to the first position and opens the button hole.
Second press of the start switch starts the machine.
This facility is used for easy to handle garments and more experienced operators.
POSITION 3. Gives 3 step action.
First press of the start switch will lower the clamp to the first position to allow the fingers to be aligned with the button hole.
Second press of the start switch will lower the clamp to the second position and open the button hole.
Third press of the start switch will start the machine.
