3. Setup and Installation

3.1 Mounting

The Leeson Model 110142 motor features a rigid base designed for secure mounting on equipment. Ensure the mounting surface is stable, level, and capable of supporting the motor's weight and operational forces.

1. Position the motor on the desired mounting surface.
2. Align the motor shaft with the driven equipment.
3. Secure the motor using appropriate bolts and washers through the mounting holes on the rigid base. Tighten all fasteners evenly to prevent vibration and misalignment.
4. Verify that the motor is firmly attached and there is no wobble or movement.

3.2 Electrical Connections

This motor operates on 115/208-230 Volts, Single Phase. Refer to the wiring diagram located on the motor's nameplate or inside the terminal box cover for specific connection instructions. Always ensure power is disconnected before making any electrical connections.

• Confirm the supply voltage matches the motor's voltage requirements (115V, 208V, or 230V).
• Connect the power supply wires to the appropriate terminals as indicated by the wiring diagram.
• Ensure all connections are tight and secure to prevent arcing and overheating.
• Properly ground the motor frame to an earth ground.
• Close and secure the terminal box cover after connections are complete.

4. Operating Instructions

4.1 Pre-Operation Check

• Verify all mounting bolts are tight.
• Ensure all electrical connections are secure and properly insulated.
• Check that the motor shaft rotates freely without obstruction.
• Confirm that the driven equipment is ready for operation.

4.2 Starting the Motor

Once all pre-operation checks are complete, apply power to the motor. The motor should start smoothly and reach its rated speed of 3,450 RPM quickly.

4.3 Manual Reset Overload Protection

This motor is equipped with a manual reset overload protector. This feature safeguards the motor from damage due to excessive current or overheating. If the motor stops unexpectedly during operation, it may be due to the overload protector tripping.

• If the overload trips, disconnect power to the motor immediately.
• Allow the motor to cool down for at least 10-15 minutes.
• Investigate the cause of the overload (e.g., excessive load, low voltage, poor ventilation).
• Once the motor has cooled and the cause is addressed, press the manual reset button (typically a red button on the motor housing or terminal box) to reset the protector.
• Reconnect power and attempt to restart the motor. If the overload trips repeatedly, consult the troubleshooting section or a qualified technician.

5. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Leeson electric motor. Always disconnect power before performing any maintenance.

5.1 Cleaning

The totally enclosed, fan-cooled (TEFC) design and full gasketing significantly reduce the ingress of wood dust and shavings. However, external cleaning is still important.

• Periodically clean the exterior of the motor, especially the cooling fins and fan cover, to ensure proper airflow and heat dissipation.
• Use compressed air or a soft brush to remove accumulated dust and debris.
• Do not use water or liquid cleaners directly on the motor.

5.2 Inspection

• Regularly inspect the motor for any signs of damage, loose connections, or unusual wear.
• Check mounting bolts for tightness.
• Listen for any unusual noises during operation, which could indicate bearing issues or misalignment.
• Inspect the power cord and plug for damage.

5.3 Lubrication

Leeson motors are typically designed with sealed bearings that do not require periodic lubrication. Refer to the motor's nameplate or specific documentation for your model to confirm lubrication requirements. If your motor has grease fittings, consult a qualified technician for proper lubrication procedures and schedules.
