1. Safety Precaution :
Please read this manual with sewing machine manual thoroughly and pay attention for the
following safety precaution.
˙Installation and operation must be done by the trained personnel, also turn off the power switch and remove the plug
from outlet and wait for 5 minutes before any installation.
˙This product is designed for the specific sewing machines and must not be used for other purposes.
˙Only use the power voltage as described on the name plate of the motor and control box in ±10 % ranges.
※Attention : If the control box is AC 220V system, please don’t connect to the AC 380V
power outlet, otherwise the error will occur and motor is not functional. If that
happened, please turn off the power switch immediately and check the power
voltage. Continue supply the 380V power over 5 minutes might damage the
fuses and burst the electrolytic capacitors and even might endanger the
person safety.
˙In order to prevent abnormal operation, keep the product away from the high frequency machines.
˙Don’t operate in direct sun light、outdoors area and the room temperature is 45°C above or 5°C under.
˙Don’t operate near the heater、dew area and the humidity is 30 % less or 95% more.
˙Don’t operate in dusty、evaporate、combustible gas area, and stay away from corrosive material.
˙Don’t apply heavy objects or excessive force on the power cord, also don’t bend or pull the power cord.
˙In order to prevent the static interference and current leakage, all grounding works must be done properly.
˙After power on the machine for the first time, use low speed to operate and check the correct rotation direction.
˙During machine operation, don’t touch any moving parts.
˙All moving parts must have protective device to avoid the body contact and objects insertion.
˙Maintenance and repair must be done by the properly trained technician, also all the spare parts for repair must be
approved or supplied by the manufacturer.
˙Don’t use any objects or force to hit or ram the product.

b). Adjust on position
1. Takes off hand wheel of sewing machine.
2. Turns the shaft gets the scale stop at highest point
(or the point of up position in sewing machine).
3. Turn the encoder disc and the screw (A) to aim at
wire outlet of motor.
Remark: above description is a standard of position adjustment,
if the position is not satisfy pleases adjust till it match
your requirement.

a). Motor Installation
1. Takes off the heat exhaust fan and pulley of sewing machine.
2. Puts coupling into shaft of sewing machine, heat exhaust fan
closes to shaft. Fix coupling in shaft by bushing.
Caution:in case the sewing machine dose not reserve screw hole
3. Fix the set screw of coupling。
Warning:clamp sets crew of coupling mustfix in flat surface of shaft or
carve.
4. Fix M 5 motor on fan cover.
Warning: there is against dull design for coupling of sewing
and motor, joint direction must pay more attention
on it.there is against dull design for coupling
of sewing and motor, joint direction
must pay more attention on it。
5. Fix fan cover of motor.
