Richmat HJA58 Head Actuator Replacement Manual
Model: HJA58
Introduction
This manual provides essential information for the installation, operation, and maintenance of the Richmat HJA58 Head Actuator. This actuator is designed as a replacement part for adjustable beds and hospital beds, specifically for the head section. Please read this manual thoroughly before installation and use to ensure proper function and safety.
Safety Information
- Always disconnect power to the adjustable bed before attempting any installation, removal, or maintenance of the actuator.
- Ensure all connections are secure and correct before restoring power.
- Do not attempt to open or repair the actuator yourself. Refer to qualified service personnel.
- Keep hands and loose clothing clear of moving parts during operation.
- Verify the model number (HJA58) on your existing actuator matches this replacement part to ensure compatibility.
- This device is designed for intermittent operation: 10% max 2min ON/18min OFF. Do not exceed this duty cycle to prevent overheating.
Product Overview
The Richmat HJA58 is a linear actuator designed to provide motorized movement for the head section of adjustable beds. It consists of a motor housing, a linear shaft (piston), and connection points for mounting and electrical supply.
Installation Instructions
- Preparation: Ensure the adjustable bed is unplugged from the power outlet. Position the bed to allow easy access to the existing actuator.
- Identify and Remove Old Actuator: Locate the actuator responsible for the head section movement. Note how it is mounted and connected. Typically, actuators are secured with pins or bolts at both ends and have a power cable connected to the bed's control box. Carefully remove the retaining pins/bolts and disconnect the power cable.
- Verify Compatibility: Before installing the new actuator, compare its physical dimensions and connection points with the old one. Confirm the model number on the new actuator is HJA58.
- Mount New Actuator: Align the new Richmat HJA58 actuator with the mounting brackets on the bed frame. Insert the retaining pins or bolts through the actuator's eyelets and secure them. Ensure the actuator is freely movable at its pivot points.
- Connect Power Cable: Carefully connect the actuator's power cable to the corresponding port on the bed's control box. Ensure the connection is firm and secure.
- Test Functionality: Once installed, plug the adjustable bed back into the power outlet. Using the bed's remote control, slowly test the head section movement. Observe for smooth operation and ensure the actuator extends and retracts fully without obstruction.
- Final Check: Before regular use, double-check all mounting points and electrical connections for security.
Note: If you encounter any difficulties during installation, it is recommended to consult a qualified technician or contact the seller for assistance.
Operation
The Richmat HJA58 actuator operates in conjunction with your adjustable bed's existing control system (remote control). Once installed, the actuator will respond to commands from the remote to raise or lower the head section of the bed.
- Press the "Head Up" button on your remote to extend the actuator and raise the head section.
- Press the "Head Down" button on your remote to retract the actuator and lower the head section.
- Avoid continuous operation for extended periods. Adhere to the specified duty cycle of 10% (2 minutes ON, 18 minutes OFF) to prevent motor overheating and ensure longevity.
Maintenance
The Richmat HJA58 actuator is designed for low maintenance. However, periodic checks can help ensure its longevity and proper function.
- Cleaning: Use a soft, dry cloth to wipe down the exterior of the actuator. Do not use abrasive cleaners or solvents. Ensure no liquids enter the motor housing.
- Inspection: Periodically inspect the mounting points and electrical connections for any signs of wear, looseness, or damage. Ensure the actuator's shaft is clean and free of debris.
- Lubrication: The actuator is pre-lubricated and generally does not require additional lubrication. If you notice unusual noise or stiffness, consult a professional.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Actuator does not move. | No power to the bed; loose electrical connection; faulty remote control; actuator motor failure. | Check if the bed is plugged in. Ensure all cables are securely connected. Test with another remote if available. If issues persist, contact seller. |
| Actuator moves slowly or with difficulty. | Overload; obstruction; low voltage; worn components. | Ensure no weight exceeds the bed's capacity. Check for obstructions around the actuator. Verify power supply. If problem continues, contact seller. |
| Unusual noise during operation. | Loose mounting; internal wear; foreign object. | Check and tighten all mounting bolts/pins. Inspect for any foreign objects. If noise persists, discontinue use and contact seller. |
| Actuator stops working after short use. | Overheating due to exceeding duty cycle. | Allow the actuator to cool down for at least 18 minutes before resuming operation. Adhere to the 10% duty cycle. |
If troubleshooting steps do not resolve the issue, do not attempt further repairs. Contact the seller or a qualified service technician.
