The RJ6W uses a high-pressure commercial-grade air-hydraulic pump mounted to the side of the bridge jack. The system requires 125 psi and 10 to 20 CFM, and a convenient foot pedal activates the jack so the vehicle can be raised to the desired height in seconds. Three lock levels help users match the jack height to the job. The locks engage automatically as the scissor arms rise and release together as the arms are lowered, giving technicians a practical balance of speed, control, and mechanical support during wheel-service work.
