The subject invention is a cooling system of an internal combustion engine having a wet-sleeve cylinder liner that improves heat reduction efficiency as compared with traditional cylinder liners. The system includes an accumulator, a cylinder actuator mechanically interconnected between the carrier frame and the boom assembly, and a metered orifice connected in fluid communication to restrict a fluid flow between the accumulator and the cylinder actuator. The message center includes a speaker, a microphone, and a display. The codes are scanned by a mobile computing device for entry into the system.
