2 Safety Instructions

- 3 -
Caution
1. Please remove your foot from the pedal when turning the power ON.
2. Always turn the power OFF when leaving the machine.
3. Do not inspect the control circuit with a tester.
4. Always turn the power switch OFF before tilting the sewing machine, replace the needle or threading the needle.
5. Always ground the grounding wire.
6. Do not use branched wiring.
7. The brakes may not function when the power is turned OFF or when there is a power failure during sewing machine operation.
8. Match the connector shape and direction, and insert securely.
9. Keep the signal wire as short as possible when connecting the external switch to the connector of control box. If it is long, malfunctions may
occur. Use a shield wire when possible.
10. Install the sewing machine away from sources of strong noise such as high-frequency welders.
11. An optical method is used for the detector's detection element so take care not to let dust or oils get on the detection plate when removing
the cover for adjustment, etc. If these do get on the plate, wipe off with a soft cloth and do not scratch the plate. Take care not to let oils
enter between the detector discs.
12. When the position detector connector or the belt has come off or when the sewing machine is completely locked, the motor will be
automatically turned OFF after a set time to prevent damage to the motor. (The motor may not turn OFF if the locking is not complete.)After
the problem has been resolved, turn the power OFF and ON and normal operation will be possible. The same operation should be taken
when the position detector or wires are broken.
13. Be sure to ground the lever unit when using it to separate from the control box.
14. Always turn off the power switch before connecting or disconnecting each connector
15. Do not alter this motor and control box including accessories to avoid any accident
The altered examples: To connect the power supply to the other device through the push button switch, to take out signals of the encoder
and the detector to use the external devices.
Our company does not assume the responsibility on any accident caused by altering.
16. A high voltage is applied inside the machine, so wait at
least 10 minutes after turning the power OFF before
opening the control box. There is a cable connecting the PCB
on the cover side with the PCB on the box side. When
disconnecting the cable, gently disconnect at the connector
section. Do not pull with force.
18. If the fuse blows, remove the cause, and replace the blown fuse with one having the same capacity.
(Front view of cover side PCB with control box cover removed.)
(Front view of box side PCB with control box cover removed.)
17. Remove the dust that has adhered on the motor's
dust-proof filter once every two to three weeks.
Dust-proof filter
If the motor is run while the
filter is clogged, the motor
may overheat and affect the
motor life.
3 Points of Caution
Always wait at least 10 minutes after
turning the power switch OFF before
opening the control box cover.

1. Installation of the motor
Open three 9mm holes on the table as seen from
the above. Install the motor securely using the
installation bolts, washers, spring washers and
nuts.
The installation bolts, etc., are included with the
motor as accessories.
3. Installation of the pulley
*To properly install, the protective cover A (motor side of the protective cover) must be
installed onto the motor before the pulley is installed. (Refer to "5. Installing the protective
cover”.)
Securely tighten the pulley.
Select the correct pulley diameter to ensure complete use of the motor performance.
Selection of the motor pulley:
Motor pulley
outer diameter (mm)
(*) The motor speed should be set at 3,600rpm. When the motor pulley diameter is selected with the above method
and the pulley diameter is too small, select the minimum pulley in the range that the belt will not slip.
(**) Refer to page 20 for the pulley diameter to be used when using the Mitsubishi thread trimming sewing machine.
4. Mounting of the belt To adjust the belt tension, press down on the center of
the belt with your hand, and turn the upper and lower nuts
of the adjustment nut to increase or decrease the center
height of the motor so that the belt dips approximately
15mm.
5 Installation
2. Installation of the control box
(1) Tighten the control box onto the motor.
(2) Insert the power cord from the motor into the connector on the
back of the control box. Insert the encoder cord from the motor
into the encoder connector on the front of the control box.
If the belt tension is too low, the medium
and low speeds will be inconsistent, and
the stopping precision will be poor.
When too tight, the motor bearings will
deteriorate.
Caution
For safety always turn the power
switch off, before adjusting the belt.
Caution
Use the JIS K6323 sewing
machine belt M-type.

2. Install the pulley and attach the belt. (Refer to "3. Installing the
pulley" and "4. Mounting of the belt".)
3. Install the "belt slip off prevention part mounting plate" onto protective cover B with the following procedures.
* Change the direction of the long and short side of the attachment plate according to the motor pulley outer diameter.
(a) For motor pulley outer diameter φ55 to φ80 (b) For motor pulley outer diameter φ80 to φ125
* Set the center of the washer to the pulley diameter indication scale and tighten the bolt.
* Confirm that the belt does not contact the attachment plate.
4. Install the "protective rod" onto the protective cover B with the following steps.
* Set the protective rod to the motor pulley rotation direction and install between the belt and motor pulley.
(a) For counterclockwise rotation (b) For clockwise rotation
* Set the center of the protective rod to the position at the center of the belt and motor pulley and tighten the bolt
5. Set protective cover B onto protective coverA,
and tighten with the four set screws.
* Confirm that the belt and motor pulley do not
contact the protective rod.
6. If necessary, adjust the position of the
"protective rod" and "belt slip off prevention part
mounting plate". Securely tighten after
adjusting.

1. Adjustment of stopping position
Adjust this position with the detector installed onto the sewing machine and while
stopping at the UP and DOWN positions.
For safety, disconnect the connector for the sewing machine.
(1) Adjustment of UP position
-Loosen the two set screws on the detector joint, and set the stop position by
rotating by hand.
-If adjustment is not possible by turning the joint, loosen the cross-recessed
screw A shown of the following figure, and turn all detector plates
simultaneously to adjust to the designated stop position.
(2) Adjustment of DOWN position
-The relation of the DOWN position and UP position will differ according to the
model, so adjust this according to the sewing machine.
-When changing the DOWN position, remove the detector cover, and turn only
the red detector plate to adjust to the designated stop position.
(The cross-recessed screw A does not need to be loosened at this time.)
-Always replace the cover after adjustment.
2. Adjustment of pedal toe down pressure, and heeling pressure
