@. SET-UP
SC-910N control box can be used for DD (direct-drive) system machine head and the belt-drive system
machine head by connecting the separately-available small-sized motor unit (M91).
When using the small-sized motor unit, it is necessary to install the motor unit to the control box before in-
stalling the control box to the table.
Install the motor unit to the control box following the instructions below.
SC-910N control box
M91 small-sized motor unit (separately-available article)
1. Installing M91 small sized motor unit
1) Lay down the control box while the rear cover is
placed under the control box.
2) Remove tie-mount A.
3) Adjust the hole section of the installing base of
M91 to the hole section of the installing plate.
4) Temporarily tighten ve places with counter-sunk
screws 1supplied with the unit as accessories.
5) Securely tighten them with hexagonal wrench
key 2 supplied with the unit as accessories.
(Caution) 1. When tightening the screw, se-
curely insert the hexagonal wrench
key into the screw hole section to
tighten.
2. Hexagonal wrench key is attached
to M91.
3. Be careful that the motor shaft does
not hit against anything. (If a strong
shock is given to the motor shaft,
there is the possibility that the mo-
tor is damaged.)

2. Installing to the table
1) Install the control box to the table with the tting
bolt (asm.) supplied with the unit as accessories.
At this time, insert the nut and washer supplied
with the unit as accessories as shown in the g-
ure so that the control box is securely xed.
2) Set the machine head to the table after installing the control box (or with small-sized motor) to the
table. (Refer to Instruction Manual for the sewing machine.)
3. Adjusting the belt (when M91 is used)
1) Adjust the belt tension by turning upper and lower
nuts 1 of the adjustment bolt and adjusting the
height of the center of the motor so that the belt
sags 15 mm (9.8N) when the center of the belt is
pressed by hand.
(Caution) 1. When the belt tension is exces-
sively low, medium or low speed
rotation becomes uneven, or stop
accuracy is deteriorated. When the
tension is excessively high, dete-
rioration of the motor is advanced.
So, be careful.

4. Adjusting the belt cover (when M91 is used)
1) Adjusting the clearance of the cover
Loosen cover setscrew 1and adjust so that the
left and right clearances between the belt cover
and the belt are equal to each other.
(Caution) 1. Perform the adjustment of the cov-
er with the hexagonal wrench key
supplied with the unit as accesso-
ries. At this time, be careful that the
screw is not excessively loosened.
2) Adjusting the roll-in prevention pin
Adjust the roll-in prevention pin with the hexago-
nal wrench key supplied with the unit as acces-
sories so that the clearance between the belt and
roll-in prevention pin 2is approximately 4 mm.
(Caution) 1. Be careful of the direction of rota-
tion of the motor and determine the
position of the pin. (Position shown
in the figure is the installing posi-
tion when the motor rotates in the
direction of the arrow mark.)
2. Perform the adjustment of the cov-
er with the hexagonal wrench key
supplied with the unit as accesso-
ries. At this time, be careful that the
screw is not excessively loosened.
3) Adjusting the off-belt prevention pin
Adjust the off-belt prevention pin with the hexag-
onal wrench key supplied with the unit as acces-
sories so that the clearance between the belt and
off-belt prevention pin 3is approximately 3 mm.
(Caution) 1. Perform the adjustment of the cov-
er with the hexagonal wrench key
supplied with the unit as accesso-
ries. At this time, be careful that the
screw is not excessively loosened.
4) Installing the belt cover
Adjust the notch section of the pulley outer cover
4to the gap of screw 5of the pulley inner cov-
er and insert the outer cover to the inner cover.
