4. Setup Instructions
Follow these steps to set up your Richmat HJA58 Electric Linear Actuator system:
- Unpacking: Carefully unpack all components, including the linear actuators, control box, power supply, and hand controller(s).
- Mounting Actuators: Securely mount the linear actuators to your application (e.g., adjustable bed frame, sofa mechanism) using appropriate hardware. Refer to the external dimension diagram (Figure 2) for precise measurements.
- Connecting Actuators to Control Box: Connect each linear actuator to the corresponding port on the Richmat control box. The control box typically has labeled ports such as 'HEAD', 'FOOT', 'LUMBAR', and 'TILT'. Ensure connections are firm and secure.
Video 1: System Components and Connections
- Connecting Power Supply: Connect the power supply to the control box and then plug the power supply into a suitable electrical outlet.
- Connecting Hand Controller: Plug the hand controller into the designated port on the control box or branching device.
- Expanding Functions (Optional): If using additional accessories or actuators, connect them to the branching device, which then connects to the main control box.

5. Operating Instructions
Once the system is properly installed and powered, you can operate the linear actuators using the hand controller:
- Power On: Ensure the system is connected to power. The control box may have an indicator light to show it's active.
- Using the Hand Controller: Press the corresponding buttons on the hand controller to adjust the position of the connected actuators. Buttons are typically labeled for 'HEAD', 'FOOT', 'LUMBAR', 'TILT', 'FLAT', 'ZG' (Zero Gravity), 'TV', and memory presets ('M').
- Stopping Motion: Press the 'STOP' button to halt any ongoing movement.
- Phone Charging: If your system includes a USB socket, you can plug your mobile device into it for charging.

6. Maintenance
To ensure the longevity and optimal performance of your Richmat HJA58 Linear Actuator, follow these maintenance guidelines:
- Regular Cleaning: Keep the actuator and control box free from dust and debris. Use a soft, dry cloth for cleaning. Avoid using harsh chemicals or abrasive materials.
- Inspect Connections: Periodically check all electrical connections to ensure they are secure and free from damage.
- Lubrication: The internal components are pre-lubricated and generally do not require additional lubrication. If you notice unusual friction or noise, contact support.
- Avoid Overloading: Do not exceed the maximum push/pull force specified for the actuator (8000N push, 4000N pull). Overloading can lead to premature wear and failure.
- Environmental Conditions: Ensure the actuator operates within its specified IP20 rating (drip-proof). Avoid exposure to excessive moisture or extreme temperatures.
7. Troubleshooting
If you encounter issues with your linear actuator, try the following steps:
- No Movement:
- Check if the power supply is securely plugged into both the control box and the wall outlet.
- Verify that all actuator cables are correctly and firmly connected to the control box.
- Ensure the hand controller is properly connected and its batteries (if applicable) are functional.
- Intermittent Movement:
- Inspect cables for any signs of damage or loose connections.
- Ensure the actuator is not obstructed or experiencing excessive load.
- Unusual Noise:
- Check for any obstructions around the actuator's moving parts.
- Ensure the actuator is securely mounted and not vibrating against other surfaces.
- Actuator Overheating:
- Reduce the duty cycle or allow the actuator to cool down if it has been operating continuously under heavy load.
- Ensure adequate ventilation around the actuator and control box.
If the problem persists after performing these checks, please contact Richmat customer support.
8. User Tips
- Installation Planning: Before installation, carefully review the external dimension diagram (Figure 2) to ensure proper fit and clearance for the actuator's stroke.
- System Compatibility: When connecting to other Richmat products or accessories, ensure compatibility to avoid electrical or mechanical issues.
- Cable Management: Route cables neatly and securely to prevent pinching, snagging, or accidental disconnection, which can prolong the life of your system.
