󱢳
󱢴
1) Connect the terminals of power cord ❶of the
SC-950(951) to reactor-box PCB asm. ❷and
to reactor box mounting plate ❸.
Connect brown wire A to the rst connector
and blue wire Bto the third connector respec-
tively from the top of terminal block on the
reactor box PCB asm. using screws. Connect
green/yellow wire Cto reactor box mounting
plate ❸with earth setscrew ❹.
2) Attach cable clip ❺to the power cord of SC-
950(951). Attach the power cord together with
the cable clip to reactor box mounting plate ❸
with cable clip setscrew ❻.
3) Attach cord bushes ❽to input/output cables
❶and ❼of the reactor box. Attach both bush-
es in the same manner.
4) Attach reactor box cover 󱢳to reactor box
mounting plate ❸with four reactor-box cover
setscrews ❾.
At this time, x cord bushes ❽attached to
input/output cables ❶and ❼in the concave
section on reactor box cover 󱢳to eliminate a
gap between reactor box 󱢴and cover 󱢳.
5) Install reactor box 󱢴on the table stand with
four accessory wood screws 󱢵at the position
that is approximately 200 mm away from the
front end of table stand.
Adjust the installing position according to the
size of table stand so that the reactor box does
not protrude from the edge of table stand.
6) Fix input/output cables ❶and ❼of reactor
box 󱢴on the table stand using accessory cord
staple 󱢶.
At this time, take care not to cross the input-
and output-cables.

DANGER :
1. To prevent personal injuries caused by electric shock hazards or abrupt start of the sewing
machine, carry out the work after turning OFF the power switch and a lapse of 5 minutes or more.
2. To prevent accidents caused by unaccustomed work or electric shock, request the electric expert
or engineer of our dealers when adjusting the electrical components.
Securely x the cords to be connected
to CN20, CN21 and CN22 with cable
clamp ❸.
Check the connector markers of
CN21 and CN22 to prevent improper
connection.

2-8. Handling the cords
2-9. Attaching the connecting rod
1) Bring the cords under the table into the control
box.
2) Put the cord brought into the control box through
cord exit plate ❶ and x cable clip band ❷.
3) Install control box cover ❸with four setscrews ❹.
Arrange the cord so that it is not tensed
or hitched even when the machine head
is tilted. (See A section.)
1. If the screw is excessively loosened,
the spring will come off. Loosen the
screw to such an extent that the top
of the screw can be observed from
the case.
2. Whenever you have adjusted the
screw, be sure to secure the screw by
tightening metal nut ❺ to prevent the
screw from loosening.
1) Fix connecting rod ❶to installing hole Bof pedal
lever ❷with nut ❸.
2) Installing connecting rod ❶to installing hole A
will lengthen the pedal depressing stroke, and the
pedal operation at a medium speed will be easier.
3) The pressure increases as you turn reverse de-
pressing regulator screw ❹in, and decreases as
you turn the screw out.

The pedal is operated in the following four steps :
1) The machine runs at low sewing speed when you lightly
depress the front part of the pedal. B
2) The machine runs at high sewing speed when you further
depress the front part of the pedal. A(If the automatic
reverse feed stitching has been preset, the machine runs
at high speed after it completes reverse feed stitching.)
3) The machine stops (with its needle up or down) when you
reset the pedal to its original position. C
4) The machine trims threads when you fully depress the
back part of the pedal. E
* When the auto-lifer (AK device) is used, one more op-
erating switch is provided between the sewing machine
stop switch and thread trimming switch.
The presser foot goes up when you lightly depress the
back part of the pedal D, and if you further depress the
back part, the thread trimmer is actuated.
When starting sewing from the state that the presser foot
has been lifted with the Auto-lifter and you depress the
back part of the pedal, the presser foot only comes down.
• If you reset the pedal to its neutral position during the au-
tomatic reverse feed stitching at seam start, the machine
stops after it completes the reverse feed stitching.
• The machine will perform normal thread trimming even
if you depress the back part of the pedal immediately
following high or low speed sewing.
• The machine will completely perform thread trimming
even if you reset the pedal to its neutral position immedi-
ately after the machine started thread trimming action.

2) Fill the oil tank with the oil until the top end of
oil amount indicating rod ❸comes between the
upper engraved marker line Aand the lower
engraved marker line Bof oil amount indicating
window ❷.
If the oil is lled excessively, it will leak from the
air vent hole in the oil tank or proper lubrication
will be not performed. In addition, when the oil is
vigorously lled, it may overow from the oil hole.
So, be careful.
3) When you operate the sewing machine, rell oil if
the top end of oil amount indicating rod ❸comes
down to the lower engraved marker line Bof oil
amount indicating window ❷.
2-12. Lubrication
WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent accidents
due to abrupt start of the sewing machine,
2. To prevent the occurrence of an inammation or rash, immediately wash the related portions if oil
adheres to your eyes or other parts of your body.
3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children
cannot reach.

When polyester lament thread is used, if the indented part of the needle is tilted toward
operator's side, the loop of thread becomes unstable. As a result, hangnail of thread or thread
breakage may occur. For the thread that such phenomenon is likely to occur, it is effective to
attach the needle with its indented part slightly slanting on the rear side.
