User manual KOMATSU WA380-6 BROCHURE

[. . . ] Auto L mode is for fuel saving operation with the gear shift timing set at lower speeds than Auto H mode. Therefore Auto L mode keeps the engine run in a relatively low rpms range for fuel conservation while yielding adequate tractive force by depressing the accelerator pedal. WA380-6 WA380-6 High Performance SAA6D107E-1 Engine Electronic Heavy Duty Common Rail fuel injection system provides optimum combustion of fuel. This system also provides fast throttle response to match the machine's powerful tractive effort and fast hydraulic response. Shift mode selection switch Variable displacement piston pump & CLSS New design variable displacement piston pump combined with the Closed-center Load Sensing System delivers hydraulic flow just as the job requires preventing wasting hydraulic pressure. New Variable Displacement Piston Pump: The pump delivers only necessary amounts minimizing waste loss. Net: 142 kW 191 HP Low Emission Engine This engine meets EPA Tier 3 emission regulations and EU Stage 3A emission regulations, without sacrificing power or machine productivity. Low Fuel Consumption The fuel consumption is reduced greatly because of the low-noise, high-torque engine and the large-capacity torque converter with maximum efficiency in the low-speed range. Pump Valve Quick movement Feedback Feedback Pump Valve Slow movement Dual-Mode Engine Power Select System This wheel loader offers two selectable operating modes-- E and P. [. . . ] A specially designed two-spoke steering wheel allows the operator to easily see the instrument panel. Maintenance Control and Troubleshooting Functions Action code display function: If the loader has any troubles, the monitor displays action details on the character display at the center bottom of the monitor. Monitor function: Controller monitors engine oil level, pressure, coolant temperature, air cleaner clogging, etc. Replacement time notice function: Monitor informs replacement time of oil and filters on LCD when it reaches replacement intervals. Trouble data memory function: Monitor stores abnormalities for effective troubleshooting. Ease of Radiator Cleaning If the machine is operating in adverse conditions, the operator can reverse the hydraulic cooling fan from inside the cab by turning on a switch on the control panel. Cathion Electrodeposition Primer Paint/ Powder Coating Final Paint Cathion electrodeposition paint is applied as a primer paint and powder coating is applied as topcoat to the exterior metal sheet parts. This process results in a beautiful rust-free machine, even in the most severe environments. Some external parts are made of plastic providing long life and high impact resistance. Automatic Reversible Fan (option) The engine fan is driven hydraulically. The fan revolves in reverse for 2minutes every 2 hours intermittently. (Default setting) Sealed DT Connectors Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance and dust resistance. B: Manual Reverse Mode A: Normal rotation Mode C: Auto Reverse Mode 6 7 WA380-6 W HEEL L OADER WHEEL LOADER OPERATOR ENVIRONMENT Easy Operation Automatic Transmission with ECMV Automatic transmission with ECMV automatically selects the proper gear speed based on travel speed, engine speed, and other travel conditions. The ECMV (Electronically Controlled Modulation Valve) system engages the clutch smoothly to prevent lags and shocks when shifting. This system provides efficient machine operation and a comfortable ride. Kick-down switch: Consider this valuable feature for added productivity. With the touch of a finger, the kick-down switch P E One push power-up function kick-down switch 1st 2nd PE 1st hold 2nd 3rd 4th WA380-6 WA380-6 Comfortable Operation Variable Transmission Cut-off System The operator can continuously adjust the transmission cut-off pressure desired for the left brake pedal using switch located on the right-side control panel. The operator can improve the working performance by setting the cut-off pressure properly depending on working condition. 1 auto change Fingertip Work Equipment Control levers with Large size arm rest New PPC control levers are used for the work equipment. The operator can easily operate the work equipment with fingertip control, reducing operator fatigue and increasing controllability. The PPC control lever column can be slid forward or rearward and the large size arm rest can be adjusted up or down to provide the operator with a variety of comfortable operating positions. Low-noise Design Noise at operator's ear noise level : 72 dB(A) Dynamic noise level (outside): 108 dB(A) The large cab is mounted with Komatsu's unique ROPS/FOPS viscous mounts. The low-noise engine, hydraulically driven fan, and hydraulic pumps are mounted with rubber cushions, and the cab sealing is improved to provide a quiet, low-vibration, dustproof with pressurizing, and comfortable operating environment. Automatic shifts in ranges two through four keep production high and manual shifting at a minimum. 8 Photo may include optional equipment. 9 WA380-6 W HEEL L OADER DIMENSIONS Measured with 20. 5-25-16PR (L3) tires, ROPS/FOPS cab WHEEL LOADER SPECIFICATIONS ENGINE Model .
