Info

The cab is pressurized to keep out dust, and the filtered ventilation system combines with automatic climate control to maintain a constant, comfortable environment. The monitor provides full-color graphic displays with comprehensive machine information presented in either an English or ISO format. The monitor provides fluid level checks when the engine is started, can list approaching service intervals and can display real-time fuel consumption information numerically. Flexible power modes—high power or economy—allow the operator to adjust machine performance to the task. Both modes provide the same digging forces, but the economy mode allows the machine to work with fuel-saving efficiency when production requirements are less critical. For the operator‘s convenience, height of the controllever consoles is adjustable, and the response and modulation of the electro-hydraulic joysticks can be adjusted through the monitor. The control-pattern changer, also accessible through the monitor, allows the operator to select preferred lever functions. In addition, the monitor displays images from the 390D L‘s optional rearview and Wide Area Vision System cameras, the latter mounted on the boom or side of the machine. To diminish heat and noise in the cab, the hydraulic control valve, pumps and reservoir are positioned on Issue 04 | 2010 NEWS & REPORTS the right side of the machine away from the operator‘s station. Standard halogen lights provide exceptional jobsite illumination but can be replaced with optional High Intensity Gas lights on the boom and upper cab if more illumination is required. Cab Lights are time delayed to allow safe exit from the machine at night. And to maintain good communication, the 390D L‘s cab is two-way radio ready. Service Improvements The 390D L uses an electric fuel priming pump, which simplifies filter changes. A dual-element air cleaner with a double radial seal is standard. All filters, except for the high-pressure fuel filter, are accessible from the left side of the machine. Service safety features include a 24-volt service light receptacle and wider, 500-mm walkways that provide sure-footed access to maintenance points. To facilitate easier, environmentally sound routine maintenance, the 390D L is equipped with protected, valve-controlled fluid-drain ports and self-contained hoses for fuel, coolant and lubricant systems. Easy-tochange spinon filters are used in the fuel and lubricant systems, and pressurized fluid sampling ports (in all pressurized fluid circuits) assure reliable fluid samples. www.advanced-mining.com 144

Lift Capacity* An electronic warning system alerts the operator if the air filter or hydraulic filter is approaching restriction limits. The Electronic Power Control (EPC) has been relocated from the cab (its position in the 385C) to the 390D L‘s air cleaner compartment, allowing the cab floor to be washed without risk of damage to the EPC. For further reliability, the EPC and its electrical terminals are weather-proof.
