Setup and Installation
1. Mounting the Motor
The motor is designed for under-table mounting. Use the provided carriage bolts, nuts, and rubber vibration dampeners to secure the motor to your sewing machine table. Ensure the rubber dampeners are positioned between the motor and the table, with the small extension facing the motor, to minimize vibration transfer.

2. Belt Installation and Adjustment
Connect the motor's pulley to your sewing machine's handwheel using a V-belt (typically 3/8-inch width, 39-42 inches in length). Adjust the belt tension using the two nuts on the threaded rod of the motor's mounting bracket. The belt should be taut but not overly tight.

3. Foot Pedal Linkage
Attach the provided linkage rod to the motor's control arm and your sewing machine's foot pedal. This linkage translates foot pedal movement into motor speed control.
4. Electrical Connection
Plug the motor's power cord into a standard AC110V, 60Hz outlet. The motor also features a 110V outlet on its back for connecting a sewing light, which will turn on automatically with the motor.
Operating Instructions
1. Power On/Off
Use the red switch on the external power switch box to turn the motor on or off. The motor's digital display will illuminate when powered on.
2. Speed Adjustment
The motor's speed is primarily controlled by the foot pedal. For finer control or to limit the maximum speed, use the speed adjustment knob located on the motor's control panel. Rotate the knob to set your desired maximum RPM.

Maintenance
- Regularly inspect the motor and belt for any signs of wear or damage. Replace worn parts promptly.
- Keep the motor clean and free from dust and lint, which can accumulate and affect performance.
- Check electrical connections periodically to ensure they are secure.
- The motor is designed for long-term use with minimal maintenance. Carbon brushes are included as spares but typically do not require immediate replacement.
Troubleshooting
- Motor not starting: Check the power connection, ensure the power switch is on, and verify the fuse in the switch box.
- Irregular speed or power: Ensure the belt tension is correct and the foot pedal linkage is properly connected and moving freely. Check the speed adjustment knob setting.
- Excessive noise or vibration: Confirm the motor is securely mounted and the vibration dampeners are correctly installed. Inspect the belt for damage or misalignment.
- Motor running in wrong direction: Use the direction reversal switch on the motor to correct the rotation.
