The recliner's movement is controlled by the included 2-button 5-pin hand control. This control typically features two buttons for extending and retracting the recliner mechanism.
- Extend: Press and hold the 'Extend' button (usually indicated by an arrow pointing outwards or a 'recline' symbol) to move the recliner to an extended position.
- Retract: Press and hold the 'Retract' button (usually indicated by an arrow pointing inwards or an 'upright' symbol) to return the recliner to its upright position.
Release the button once the desired position is reached. The motor is designed for intermittent use, as detailed in the specifications section.

4. Maintenance
Proper maintenance ensures the longevity and reliable operation of your motor actuator.
- Regular Inspection: Periodically inspect all cables and connections for signs of wear, fraying, or damage. Ensure connections remain secure.
- Cleanliness: Keep the motor and surrounding area free from dust and debris. Use a dry cloth for cleaning. Avoid using liquid cleaners directly on electrical components.
- Environmental Conditions: This product is designed for indoor use only. Avoid exposure to moisture, extreme temperatures, or direct sunlight.
- Intermittent Use: The motor has an interuptime rating of 0.5 minutes of operation followed by 4 minutes of rest. Avoid continuous operation for extended periods to prevent overheating and potential damage.
5. Troubleshooting
If your recliner is not functioning correctly, perform the following troubleshooting steps before seeking professional assistance.
- No Movement:
- Ensure the recliner is securely plugged into a working wall outlet.
- Check all cable connections between the motor, power supply, and hand control. Ensure the 5-pin connector is fully inserted.
- Verify that the power supply transformer is receiving power (some transformers have an indicator light).
- Intermittent Operation:
- Check for loose connections.
- Ensure the motor is not overheating due to prolonged continuous use. Allow it to cool down if necessary, adhering to the interuptime specification.
- Remote Not Responding:
- Inspect the hand control cable for any damage or kinks.
- Ensure the 5-pin connector is firmly seated in the motor actuator.
If issues persist after performing these checks, contact the seller or manufacturer for further support.
