1-3. Adjusting the vertical stroke of the intermediate presser
* Turn ON the power once, and turn OFF the
power again after making the intermediate
presser in the lowered state.
1) Remove face cover.
2) Turn handwheel to make the needle bar come
down to its lowest point.
3) Loosen hinge screw
and move it to the di-
rection A to increase the stroke.
4) When marker dot
is aligned with the right
side of the outer periphery of washer
, the
vertical stroke of the intermediate presser
becomes 4 mm. And, when marker dot
is
aligned with the right side of the outer periphery
of the washer, it becomes 7 mm. (The vertical
stroke of the intermediate presser is factory-set
to 4 mm at the time of delivery.)
By removing the rubber plug in the face plate
cover, adjustment can be performed without
removing the face plate cover.
1-2. Adjusting the height of the feeding frame
1) Loosen setscrews
located on the right and left
sides of feed bracket
. Moving cloth presser
link
to the direction A will decrease the height
of the feeding frame.
2) After the adjustment of the height of the feeding
frame, securely tighten the screws
.
If the feeding frame still interferes with the face
plate bearing and the feeding frame height does
not change after the adjustment of the position
of work clamp link, adjust the pressure applied
to the face plate bearing to lower it as far as no
lateral play of the feeding frame occur.
At the time of delivery, work clamp foot has been
moved up and down to adjust the torque (sliding
torque) of face plate bearing
to 0.98 to 7.84 N (100
to 800 g) applied when work clamp foot starts mov-
ing after face plate bearing
has come in contact
with the spring pin.
1. Loosen the setscrew
.
2. Lightly tighten the pressure adjusting screw
and give a pressure to the face plate
bearing
. At that time, move the presser
foot face plate
vertically, making sure that
uneven application of torque can be avoided.
3. Tighten the setscrew
.
1. When the setscrew
is tightened,
pressure kept applied to the face
plate bearing
is changed.
Therefore, when the setscrew
is
tightened, examine the amount of
the slippage torque.
2. The pressure adjusting screw
is
not attached to the sewing machine.
WARNING :
Turn OFF the power before starting the work so as to prevent accidents caused by abrupt start of
the sewing machine.
