Before installing, it is critical to verify that this motor is compatible with your existing recliner or lift chair. Incompatibility can lead to improper function or damage.
- SKU Verification: Ensure the SKU "1.28.000.131.30" is present on the label of your old motor.
- Cable Connectors: Confirm that the shapes of the cable connectors on this motor match those of your existing unit.
- Motor End Shapes: Verify that the motor end shapes are identical to your current motor.

3. Troubleshooting Before Motor Replacement
Often, issues with a recliner or lift chair are not due to a faulty motor. Before replacing the motor, perform the following checks:
- Check the Switch/Remote: Test the chair's switch or remote control. If possible, try using a switch from a working recliner to rule out a faulty control unit.
- Check the Power Supply: Ensure the power supply unit is functioning correctly and providing adequate power to the chair.
These steps can help identify if the motor is indeed the component requiring replacement.

4. Installation Instructions
Safety First: Always unplug the recliner or lift chair from the power outlet before attempting any installation or maintenance.
- Prepare the Chair: Position the recliner or lift chair in a way that allows safe and easy access to the motor area. You may need to carefully tilt the chair or lay it on its side.
- Disconnect Old Motor:
- Carefully disconnect all electrical connections from the old motor, including the power transformer connection and the hand control plug connection.
- Remove the mounting bolts, R-clips, and gear clevises that secure the old motor to the chair frame. Note their positions for reassembly.
- Remove Old Motor: Once disconnected and unmounted, carefully remove the old motor from the chair.
- Install New Motor:
- Position the new Okin Deltadrive motor in the same location as the old one.
- Secure the new motor using the mounting bolts, R-clips, and gear clevises. Ensure all connections are tight and secure. Refer to the diagram for component identification.
- Reconnect Electrical: Reconnect the 2-pin flat round power transformer connection and the 5-pin hand control plug connection to the new motor. Ensure connections are firm.
- Test Functionality: Plug the chair back into the power outlet. Carefully test the recliner's functions (recline, lift) to ensure the new motor operates smoothly and correctly.

5. Connection Guide
The Okin Deltadrive motor features two primary electrical connections:
- 2-Pin Flat Round Power Transformer Connection: This connector supplies power to the motor from the chair's power transformer.
- 5-Pin Hand Control Plug Connection: This connector interfaces with the chair's hand control or remote, allowing user operation.
Ensure these connections are securely and correctly plugged into their corresponding ports on the chair's wiring harness.

6. Operation
Once the motor is correctly installed and all connections are secure, the recliner or lift chair should operate as intended using its original hand control or remote. The motor facilitates the smooth extension and retraction of the chair's mechanisms.
- Press and hold the appropriate button on your hand control to recline or lift the chair.
- Release the button to stop the movement at the desired position.
Avoid forcing the chair's movement manually, as this can damage the motor or the chair's mechanism.
7. Maintenance
To ensure the longevity and optimal performance of your Okin Deltadrive motor, follow these simple maintenance guidelines:
- Cleaning: Wipe the motor and surrounding areas clean with a dry or slightly damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Inspection: Periodically inspect all connections and mounting points for any signs of loosening or wear. Tighten as necessary.
- Avoid Overloading: Do not exceed the weight capacity of your recliner or lift chair, as this can strain the motor.
