SET-UP Install the motor unit to the control box following the instructions below. 1. Installing the motor unit Install the motor unit on the table with the fitting bolt asm. supplied with the unit as accessories. At this time, insert the nuts and washers supplied with the unit as accessories as shown in the figure so that the motor unit can be securely fixed on the table. 1 1) Press three bolts 1 supplied with the unit as accessories into the motor hanging bolt hole in the table and fix them. 2) Temporarily tighten convex washer, spring washer and nut on the side where two bolts are attached. Convex washer Nat Spring washer 3) Hang the motor unit to the washer which has been temporarily tightened, and attach convex washer, spring washer and nut to the other bolt on the opposite side. 4) After adjusting the installing position of the motor, securely tighten the respective nuts. 2. Installing the control box 2 1) Loosen four screws 2 supplied with the motor unit as accessories, tighten screws 2 after hanging control box unit 3 to the screws, and fix control box unit 3. 3 −1− 3. Installing the belt 1) The belt distance, between sewing machine pulley and motor pulley, must be parallel. 15mm (9.8N) 2) The belt tension should be adjusted by turning the tension adjust nuts to change height of the motor, so that the belt sinks down by about 15 mm (9.8N) when it is depressed by band at the center of the belt span. If the belt tension is not tight, speed is unstable at low-speed or medium-speed operation, and the needle will not stop exactly in position. Tension adjust nuts 4. Adjusting the pulley cover 1) After adjusting the belt tension, adjust the pulley cover 1 so that the clearances between the belt and the pulley cover 1, a and b should be the same. b Belt a 1 2) After the completion of adjustment, tighten screws 2 located on the side of pulley cover 1 and securely fix the pulley cover 1 so that it does not slip out of position. 2 1 −2− 5. Installation and adjustment for the protecting pin and the belt slip-off preventing bracket WARNING : To protect against possible personal injury due to abrupt start of the machine, be sure to start the following work after turning the power off and ascertaining that the motor is at rest. 1) Attaching hole for the protecting pin 23 To attach protecting pin 1, select either attaching hole A or attaching hole B in the motor pulley cover in accordance with the direction of rotation of the sewing machine and attach the pin in the selected hole using screw 2 and washer 3 supplied with the unit. 1 a) If the motor shaft rotates in direction A in the figure on the above: / Attach protecting pin 1 in attaching hole A . b) If the motor shaft rotates in direction B in the figure on the above: / Attach protecting pin 1 in attaching hole B .

Detailed explanation of selection of functions 1 Selection of the soft-start function (Function setting No. 1) The needle thread may fail to interlace with the bobbin thread at the start of sewing when the stitching pitch (stitch length) is small or a thick needle is used. To solve such problem, this function (called “soft-start”) is used to limit the sewing speed, thereby assuring successful formation of the starting stitches. 0 : The function is not selected. 1 0 1 to 9 : The number of stitches to be sewn under the soft-start mode. The sewing speed limited by the soft-start function can be changed. (Function setting No. 37) Data setting range 3 7 8 0 0 100 to MAX rpm <50 rpm> 2 Material end sensor (ED : optional) function (Function setting No. 2 to 4) This function is possible when the material end sensor (ED) is attached.

Changing procedure between 100V to 120V and 200V to 240V (Possible only for the voltage changeover type) WARNING : 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. To prevent accidents caused by unaccustomed work or electric shock, request the electric expert or engineer of our dealers when adjusting the electrical components. Voltage can be changed between single phase 100 to 120V and single phase/3-phase 200 to 240V by changing over the voltage changeover switch. (Caution) The voltage changeover switch is on the inside of the control box. When changing the setting, be sure to open the front cover after turning OFF the power switch and a lapse of 5 minutes or more. In addition, if the changing procedure is mistaken, the control box is damaged. So, be very careful. 1) Turn OFF the power with the power switch after checking that the sewing machine has stopped. 2) Draw out the power cord from the power receptacle after checking that the power switch has been turned OFF. Then wait for 5 minutes or more. 3) Remove two screws 1 fixing the front cover and slowly open the front cover. 1 Voltage changeover switch A 110V 220V Voltage changeover switch A 110V 220V Voltage changeover switch 110V 220V A 4) hanging procedure of the power voltage (Caution) When the voltage of the power changeover switch and that of the AC input cord are wrong, the control box is damaged.

These error codes interlock (or limit function) and inform the problem so that the problem is not enlarged when any problem is discovered. When you request our service, please confirm the error codes. 5 1 Checking procedure of the error code 1) Pressing switch 1 in the control box, turn ON the power switch. 2) LED becomes display 5 with the sound of “peep” and the latest error code is displayed. 3) Confirmation of the contents of previous error can be performed by operating switches 1 or 2. (Caution) When operating switch 1, one before the existing error code is displayed. When operating switch 2, one after the existing error code is displayed. 2 Error code list No. Description of error detected Cause of occurrence expected Items to be checked E000 Execution of data initialization • When the machine head is changed.
