3. Safety Information
Adherence to safety guidelines is crucial for preventing injury and damage to the product. Please observe the following:
- Always follow the manufacturer's instructions for installation and use of the recliner or lift chair.
- Do not exceed the maximum load capacity of 1200 N (264 lbs) for the actuator.
- Keep the power cord away from heat sources, sharp objects, and moving parts to prevent damage.
- Ensure all connections are secure before operating the chair.
- Disconnect power before performing any maintenance or troubleshooting.
- In case of any doubt or malfunction, contact a qualified technician or the manufacturer.
- Max Duty Cycle: 2 minutes ON and 18 minutes OFF (10%). Do not operate the actuator continuously beyond this cycle to prevent overheating.
4. Setup and Installation
The KDPT007-334 linear actuator is designed for straightforward replacement. While specific chair models may vary, the general installation steps are as follows:
- Disconnect Power: Unplug the recliner or lift chair from the wall outlet to prevent electrical shock.
- Locate Existing Actuator: Identify the old linear actuator under the chair. Note how it is mounted and connected.
- Remove Old Actuator: Carefully detach the old actuator from its mounting points. This typically involves removing pins or bolts. Disconnect the power cable and hand control cable from the old actuator.
- Install New Actuator: Mount the new KDPT007-334 actuator in the same position as the old one, securing it with the appropriate pins or bolts (often included with the replacement part).
- Connect Cables:
- Connect the 2-pin flat round male connector from the power transformer to the actuator.
- Connect the 2-pin flat round female connector from the motor to the power supply.
- Connect the 5-pin hand control cable to the designated port on the actuator.
- Test Operation: Once all connections are secure and the actuator is properly mounted, plug the chair back into the wall outlet and test the hand control to ensure smooth operation.

Note: Detailed assembly instructions for the chair itself are typically provided by the chair manufacturer. This manual focuses on the motor replacement process.
5. Operating Instructions
The Kaidi KDPT007-334 linear actuator operates in conjunction with your recliner or lift chair's hand control unit. To operate:
- Ensure the chair is plugged into a functional power outlet.
- Use the buttons on your chair's hand control to extend or retract the footrest and backrest.
- The actuator will move at a speed of approximately 25 mm/s.
- Avoid continuous operation for more than 2 minutes. Allow at least 18 minutes of rest for every 2 minutes of operation to prevent motor overheating and ensure longevity.
6. Maintenance
Proper maintenance ensures the longevity and smooth operation of your linear actuator.
- Cleaning: Wipe the exterior of the actuator clean with a dry cloth. Avoid using harsh chemicals or abrasive cleaners.
- Keep Dry: Ensure the actuator remains dry. Avoid exposure to liquids or excessive moisture.
- Inspection: Periodically inspect the power cord and connection points for any signs of wear, fraying, or damage. Ensure all mounting hardware remains tight.
- Lubrication: The internal components of the linear actuator are factory-lubricated and generally do not require additional lubrication. Do not attempt to open the actuator housing.
7. Troubleshooting
If you encounter issues with your linear actuator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not move | No power, loose connections, faulty hand control, motor overload. | Check power cord and wall outlet. Ensure all cables (power, motor, hand control) are securely connected. Test hand control if possible. Allow motor to cool if recently used for extended periods. |
| Actuator moves slowly or intermittently | Low power, excessive load, motor overheating. | Verify power supply. Reduce load on the chair if possible. Allow motor to cool down. Check for obstructions in the chair mechanism. |
| Unusual noises during operation | Obstruction, worn components, improper installation. | Inspect the chair mechanism for any obstructions. Ensure the actuator is securely mounted and not rubbing against other parts. If noises persist, contact support. |
If troubleshooting steps do not resolve the issue, please contact customer support for further assistance.
