Operating Instructions
The Richmat HJA67S actuator motor operates as an integral part of your adjustable bed base. Its function is controlled directly by the bed's remote control or integrated control panel. There are no direct user controls on the motor itself.
- Use your adjustable bed's remote control to raise or lower the head and/or foot sections of the bed.
- The motor will activate to move the bed frame to the desired position.
- Avoid placing excessive weight on the moving parts of the bed, which could strain the motor.
Maintenance
- Cleaning: Periodically wipe the exterior of the motor with a dry, soft cloth to remove dust. Do not use liquid cleaners or abrasive materials.
- Inspection: Regularly inspect the motor and its connections for any signs of wear, damage, or loose cables. Ensure all mounting bolts remain tight.
- Lubrication: The motor is factory-lubricated and generally does not require additional lubrication. If you notice unusual noises, consult a professional.
