INSTALLATION
Mounts speed control unit and control
box under the sewing machine table.
Motor Installation
1.Take off the pulley of sewing machine, remain the exhaust fan.
2. Put washer into the shaft of sewing machine then put it in the shaft of motor, to use screw to screw tight the shaft of the motor. Note: the red mark
on motor to fix on the shaft of sewing machine by set screw.
3. Fix motor on sewing machine.
4. Put a fixture to motor then set into motor shaft, push motor to sewing machine end face by a fixture.
Note: Motor shaft sticking strong magnet, pleases pay attention to powerful magnetic while force motor to sewing machine to avoid damage the
motor or hurt your finger. Pleases throw away the assemble tooling after assembled one machine. It is prohibit to use assemble tooling repeat.
5. Put motor pulley to motor shaft then tighten the screw.
Note: pleases turn the sewing machine to up position before tighten the pulley and fix the set screw on the pulley.
After that the needle at up position while motor is stop running. Pleases release the pulley to process micro adjustment on pulley if the needle stop
position is not satisfied.
