2. Access Existing Motor: Carefully tilt the chair or remove any fabric coverings to gain access to the existing linear actuator.
3. Disconnect Old Motor: Disconnect the power cable and the hand control cable from the old motor. Note their positions for re-connection.
4. Remove Old Motor: Unbolt or unclip the old actuator from its mounting points on the chair frame. Keep any mounting hardware.
5. Install New Motor: Position the new MineCtrl R8123 actuator in the same location as the old one. Secure it using the appropriate mounting hardware. Ensure it is firmly attached and aligned correctly.
6. Connect Cables: Connect the 2-pin flat round power transformer cable to the power supply and the 5-pin hand control cable to the chair's hand control unit. Ensure all connections are secure.
7. Restore Power: Plug the power supply back into the wall outlet.
8. Test Operation: Carefully test the recliner's functions using the hand control. Ensure the actuator extends and retracts smoothly and fully.

If you encounter any issues during installation, refer to the troubleshooting section or contact customer support.

6. Operating Instructions

Once the MineCtrl RMT Linear Actuator R8123 is correctly installed, operating your power recliner or lift chair is straightforward using the existing hand control unit.

  • Test the hand control unit itself if possible (e.g., by connecting it to another working chair or testing its continuity if you have the tools).
• Incomplete Movement or Stuttering:
  • Check for any physical obstructions preventing the chair mechanism or actuator from moving freely.
  • Ensure the actuator is correctly mounted and not binding.
  • Verify that the stroke length of the installed actuator matches the original unit.
• Unusual Noises:
  • Inspect for loose components or foreign objects near the motor or shaft.
