3. Technical Specifications

Figure 2: Close-up view of the motor's identification label. This label displays critical technical specifications such as model number (DTSJ-002), rated voltage, input power, stroke length, speed, maximum load, and duty cycle. Verify this information matches your original motor before replacement.

4. Compatibility Verification

This linear actuator is a direct replacement for motors with the model number DTSJ-002, manufactured by Ding Tang. It is crucial to verify that your existing motor's model number matches DTSJ-002. This replacement motor may also be compatible with certain Mcombo recliner models that use the DTSJ-002 actuator.

Before ordering or installing, always check the label on your current motor to confirm the model number and specifications. Additionally, inspect the power supply and hand control connections to ensure they match the Fruhdi DTSJ-002's 2-pin flat round power connection and 5-pin hand control plug connection.

5. Installation Instructions

Safety First: Before beginning any installation, ensure the recliner or lift chair is unplugged from the power outlet to prevent electrical shock or accidental operation.

1. Prepare the Recliner: Carefully turn the recliner or lift chair onto its side or back to access the motor assembly. You may need assistance for larger or heavier furniture.
2. Identify Connections: Locate the existing linear actuator motor. Identify the power cable and the hand control cable connected to it.
3. Disconnect Cables:
   • Disconnect the 2-pin flat round power cable from the power transformer.
   • Disconnect the 5-pin hand control cable from the motor.

4. Remove Old Motor: Unbolt or unclip the old motor from its mounting brackets on the recliner frame. Note the orientation and how it was attached.
5. Install New Motor: Position the Fruhdi DTSJ-002 replacement motor in the same location and orientation as the old motor. Secure it using the existing bolts or clips. Ensure all mounting points are firmly attached.
6. Connect Cables:
   • Connect the 2-pin flat round power cable from the new motor to the power transformer.
   • Connect the 5-pin hand control cable to the new motor. Ensure all connections are secure and fully seated.
7. Test Functionality: Carefully return the recliner to its upright position. Plug the recliner back into a power outlet. Test the hand control to ensure the motor operates smoothly and correctly in both directions (extend and retract).
8. Final Check: Ensure no cables are pinched or obstructing the recliner's movement.

6. Operation

The Fruhdi DTSJ-002 linear actuator motor operates in conjunction with your recliner's existing hand control unit and power supply. Once properly installed, the motor will respond to commands from the hand control to extend or retract, thereby adjusting the recliner's position.

• Power On: Ensure the recliner is plugged into a functional power outlet.
• Using the Hand Control: Press and hold the appropriate buttons on your recliner's hand control to move the chair into the desired position. The motor will extend or retract the push rod to facilitate this movement.
• Duty Cycle: Note the maximum duty cycle of 2 minutes ON and 18 minutes OFF (10%). This means the motor is designed for intermittent use. Avoid continuous operation for extended periods to prevent overheating and potential damage.

7. Maintenance

The Fruhdi DTSJ-002 linear actuator motor is designed for minimal maintenance. However, periodic checks can help ensure its longevity and reliable performance:

• Visual Inspection: Periodically inspect the motor and its connections for any signs of wear, damage, or loose cables.
• Cleanliness: Keep the motor free from dust, dirt, and debris. Use a dry cloth to wipe down the exterior. Avoid using liquid cleaners directly on the motor.
• Cable Management: Ensure all cables are routed safely and are not pinched, tangled, or subjected to excessive tension.
• Lubrication: The internal components of the linear actuator are pre-lubricated and generally do not require additional lubrication. If you notice unusual noise or stiffness, consult a qualified technician.

8. Troubleshooting

If your recliner or lift chair is not operating correctly after motor replacement, consider the following troubleshooting steps:

• No Power:
  • Ensure the recliner is securely plugged into a working electrical outlet.
  • Check the power transformer and its connection to the motor (2-pin flat round connector).
  • Verify that the power outlet itself is functional by plugging in another appliance.
• Motor Not Responding to Hand Control:
  • Check the 5-pin hand control plug connection to the motor. Ensure it is fully inserted and secure.
  • Inspect the hand control unit for any visible damage or loose wires.
  • If possible, test the hand control with a known working motor or test the motor with a known working hand control to isolate the issue.
• Motor Makes Noise but Does Not Move:
  • Check for any obstructions preventing the recliner mechanism or the motor's push rod from moving.
  • Ensure the motor is securely mounted and not binding.
  • Verify the maximum load capacity (4000N) is not exceeded.
• Intermittent Operation:
  • This could be related to the duty cycle. Allow the motor to cool down if it has been operated continuously.
  • Check for loose connections in both power and control cables.

If these steps do not resolve the issue, it is recommended to contact a qualified technician or the manufacturer for further assistance.

9. Safety Information

Adhere to the following safety guidelines to prevent injury or damage:

• Always unplug the recliner from the power source before performing any installation, maintenance, or inspection.
• Do not operate the motor beyond its specified duty cycle to prevent overheating.
• Keep hands, feet, and clothing clear of moving parts during operation.
• Ensure children and pets are kept away from the recliner's moving mechanisms.
• Do not attempt to repair the internal components of the motor unless you are a qualified technician.
• Use only the specified power supply and hand control unit compatible with this motor.
