Adjustment Procedures
Results of Improper Adjustment
1. Start the Test Mode I10 (IP-400) or CP-8 (CP-20).
2. Tread on the start pedal for origin retrieval, and make adjustments by
turning the sensor slit
so that the lines combining the center of the
intermediate presser lifting shaft
, the standard hole of the interme-
diate presser lifting cam
, and the center of the cam follower
become almost a straight line.
3. Press of the panel three times. Loosen the first screw
of the
drive bevel gear
of the intermediate presser variable shaft
.
Take out the drive bevel gear
from the flat part of the intermediate
presser variable shaft
and move it in the direction of the Arrow A.
4. Using the [+] key or the [–] key, turn the intermediate presser variable
shaft
until the second screw
of the intermediate presser vari-
able arm
settles in the center of the arm’s left-side hole C. (Insert
a hexagonal wrench to adjust positioning so that the arm comes in
the center of backlash deflection.)
5. Turn the intermediate presser lifting shaft
so that the second screw
of the intermediate presser lifting cam
comes just above. Press
the drive bevel gear
of the intermediate presser variable shaft
in the direction of the Arrow B to fix it.
6. After the completion of second origin retrieval, press of the
panel twice to secure the [timing adjustment position]. In this case,
confirm that the second screw
of the intermediate presser vari-
able arm
is positioned in the center of the arm’s left-side hole C or
below it. (If the screw seems to have been positioned above the cen-
ter, return to Step 4 and repeat the above-mentioned adjustments.)
7. If the second screw
of the intermediate presser variable arm
is
not positioned in the center (or lower), loosen the setscrew
of the
sensor slit
and turn this sensor slit
in the direction of the Arrow
A for fine adjustments.
8. Make origin retrieval and confirm that the the cam follower
is lo-
cated in the parallel section of the intermediate presser lifting cam
. When the condition has been found normal, fasten the setscrew
of the drive bevel gear
and the setscrew
of the sensor slit
regularly.
(Caution) For the prevention of the sensor
from destruction,
make origin retrieval after confirming that the slit of the
sensor slit
is positioned in the center of the sensor
.
o There will be a displacement
between the variable value of the
i n t e r m e d i a t e p r e s s e r l o w e r
position and the panel setup
value.
o If there is no cam follower
in
the parallel section of the interme-
diate presser lifting cam
at the
time of origin retrieval, stepping
out may occur in the intermediate
presser motor, thus causing de-
fective stitches, generation of
sound from the face plate section,
and destruction of parts.
o If adjustments of backlash are in-
sufficient for the drive bevel gear
, stepping out may occur in the
intermediate presser motor, thus
causing defective stitches, gen-
eration of sound from the face
plate section, and destruction of
parts. .
