For setup or handling of DLU-5494N-7 (1-needle, bottom and variable top feed lockstitch machine with
automatic thread trimmer), refer to the Instruction Manual for DLU-5494N-7.
In addition, for the details of handling of SC-910 (sewing machine controller) and IP-110, similarly, refer to the
respective Instruction Manuals.
SC-910 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 (M-91).
When using the small-sized motor unit, it is necessary to install the motor unit to the control box before
installing the control box to the table.
Install the motor unit to the control box following the instructions below.

(separately-available article)
2. SET-UP
1. PREFACE
(1) Installing M-91 small sized motor unit
1. When tightening the screw, securely
insert the hexagonal wrench key into
the screw hole section to tighten.
2. Hexagonal wrench key is attached to
M-91.
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 motor
is damaged.)
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
M-91 to the hole section of the installing plate.

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
gure 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.)
(2) Installing to the table
1) Adjust the belt tension by turning upper and
lower nuts 1of the adjustment bolt and adjust
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.
(3) Adjusting the belt (when M-91 is used)
Plain
washer
Spring
washer
Hexagonal nat
When the belt tension is excessively low,
medium or low speed rotation becomes
uneven, or stop accuracy is deteriorated.
When the tension is excessively high,
deterioration of the motor is advanced.
So, be careful.
Approx. 15mm / 9.8N
