Setup, Compatibility & Care
To set up your Coulax Pro M304, charge the unit fully using the provided USB cable until the indicator light signals a full charge. Attach a DuPont head by firmly pressing it onto the metal shaft until it clicks into place. For maintenance, rinse the brush head thoroughly after every use and wipe the handle with a dry cloth. Periodically clean the base of the brush head to prevent mineral buildup. Ensure the charging port is completely dry before connecting to a USB power source to prevent corrosion or electrical faults. Brush heads should be replaced every three months or when the bristles begin to fray.
