4. Safety Information
Please read and understand all safety instructions before installing or operating the linear actuator. Failure to follow these instructions may result in electric shock, fire, serious injury, or property damage.
- Electrical Safety: Ensure the power supply matches the actuator's voltage (DC 12V). Disconnect power before any installation, maintenance, or troubleshooting. Avoid exposing electrical connections to moisture.
- Mechanical Safety: Keep hands, clothing, and other objects clear of moving parts during operation. Do not exceed the maximum load capacity of 900N (225lbs). Ensure the actuator is securely mounted to prevent accidental detachment.
- Environmental: The actuator is IP54 rated, meaning it is protected against dust ingress and splashing water. However, it is not designed for submersion. Avoid operating in extreme temperatures outside the specified range (-20°C to +65°C).
- Children and Pets: Keep children and pets away from the actuator during operation to prevent injury.
5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your linear actuator. Follow these general guidelines:
- Mounting: Use the provided mounting brackets to securely attach the actuator to a stable surface. Ensure the mounting points can withstand the maximum force exerted by the actuator. The actuator can be mounted in any orientation.
- Alignment: Ensure the actuator is properly aligned with the load it will be moving. Misalignment can cause excessive wear, reduced performance, and potential damage.
- Electrical Connection: Connect the actuator to a DC 12V power source. The actuator typically has two wires; reversing the polarity will reverse the direction of motion. Consider using a control switch or relay for easy operation and safety.
- Limit Switches: The actuator has built-in, non-adjustable limit switches that automatically stop the rod at its fully retracted and fully extended positions. Do not attempt to bypass or modify these switches.

6. Operating Instructions
Operating the linear actuator is straightforward:
- Power On: Connect the actuator to a stable DC 12V power supply.
- Extend/Retract: Apply DC 12V power to the actuator. The direction of the rod's movement (extend or retract) depends on the polarity of the voltage applied to the two wires.
- Stopping: The actuator will automatically stop when it reaches its fully extended or fully retracted position due to the internal limit switches. To stop the actuator at an intermediate position, simply cut the power supply.
- Reversing Direction: To reverse the direction of motion, reverse the polarity of the DC 12V power supply. This can be achieved using a DPDT (Double Pole Double Throw) switch or a motor control circuit.

7. Maintenance
The Homend DC12V Linear Actuator is designed for minimal maintenance. However, periodic checks can help ensure its longevity and optimal performance:
- Cleaning: Keep the actuator rod and housing clean from dust, dirt, and debris. Use a soft, dry cloth. Avoid using harsh chemicals or solvents.
- Lubrication: The internal components are pre-lubricated for life. Do not attempt to lubricate the internal mechanism.
- Inspection: Regularly inspect the mounting points, wiring, and the actuator rod for any signs of wear, damage, or corrosion. Tighten any loose fasteners.
- Environmental Protection: While IP54 rated, avoid prolonged exposure to direct heavy rain or harsh environmental conditions if possible, to maximize lifespan.
8. 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, incorrect voltage, loose wiring, overloaded, internal damage. | Check power supply (DC 12V), ensure secure connections, reduce load, inspect for damage. |
| Actuator moves in wrong direction | Incorrect wiring polarity. | Reverse the polarity of the power supply connections. |
| Actuator stops prematurely | Overload, obstruction, internal limit switch fault. | Reduce load, check for obstructions, ensure free movement. If problem persists, contact support. |
| Excessive noise during operation | Overload, misalignment, internal wear. | Reduce load, check alignment, ensure smooth movement. If noise is significant, discontinue use and contact support. |
