Setup and Installation
Follow these steps carefully to replace your existing actuator. It is recommended to have a second person assist with lifting and positioning the bed frame if necessary.
- Prepare the Bed: Disconnect the adjustable bed from its power source. Ensure the bed is in a stable position, preferably flat or slightly elevated to access the actuator.
- Identify the Actuator: Locate the existing actuator on your adjustable bed. Confirm it is the HJA58 model by checking its label.

- Remove Old Actuator: Once disconnected, carefully remove the old actuator from the bed frame.
- Install New Actuator: Position the new Richmat HJA58 actuator in the same location and orientation as the old one. Secure it using the existing mounting pins or bolts. Ensure all connections are firm and stable.

- Connect Power: Reconnect the actuator's power cable to the bed's control box or power supply. Ensure the connection is secure.
- Test Functionality: Reconnect the adjustable bed to its main power source. Carefully test the bed's functions (e.g., foot or head elevation) to ensure the new actuator operates smoothly and correctly.
Operating Instructions
The Richmat HJA58 Actuator operates in conjunction with your adjustable bed's existing control system (remote control or integrated panel). Once properly installed and connected, the actuator will respond to commands from the bed's control unit to raise or lower the specific section of the bed it is attached to.
- Ensure the bed is connected to a stable power supply.
- Use the bed's remote control or panel to activate the desired movement (e.g., foot up/down).
- Do not exceed the maximum load capacity of the bed or actuator (Max. Load: push 6000N).
- Observe the duty cycle (Max. 2min ON/18min OFF) to prevent overheating and prolong the actuator's lifespan. Avoid continuous operation for extended periods.
Maintenance
The Richmat HJA58 Actuator requires minimal maintenance.
- Cleaning: Wipe the exterior of the actuator with a dry cloth to remove dust and debris. Do not use liquid cleaners or abrasive materials.
- Inspection: Periodically inspect the actuator and its connections for any signs of wear, damage, or loose fittings. Ensure the power cable is not pinched or frayed.
- Lubrication: The actuator is factory-lubricated and does not require additional lubrication.
Troubleshooting
If you encounter issues with your Richmat HJA58 Actuator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not move. | No power to the bed; loose cable connection; remote control issue; actuator overload/overheat. |
|
| Actuator moves slowly or with difficulty. | Excessive load on the bed; mechanical obstruction; low voltage. |
|
| Unusual noises from the actuator. | Internal mechanical issue; loose mounting. |
|
If the problem persists after attempting these solutions, please contact the seller or manufacturer for further assistance. Do not attempt to disassemble the actuator.
