Machine General Information
The vibratory system assists with the initial compaction of the paving material during paving operations. The auxiliary pump provides the hydraulic oil flow to operate the vibratory motors on the screed. When the vibratory system is in operation, the vibratory motors rotate eccentric weight shafts. The speed of the motor rotation determines the vibratory frequency. The vibratory system is designed to operate continuously when material is being laid. A programmable time delay allows the machine to begin moving before the vibratory system starts.Note: The machine electronic control system logic prevents the vibratory system from operating while the propulsion mode is set to travel.Note: These machines are configured with one of two different engines. One engine meets US EPA Tier 4 Final and EU Stage IV emission standards. The second engine meets US EPA Tier 3, EU Stage IIIA, and China Stage II emissions standards. Illustrations throughout this section may show components unique to either configuration. Components relevant to this section are discussed as required.
