User manual KOMATSU WA480-6 BROCHURE

[. . . ] This significantly assists productivity and also delivers great value for load-and-carry operations. WA480-6 WA380-6 Automatic Transmission with Mode Select System This operator controlled system allows the operator to select manual shifting or two levels of automatic shifting (low, and high). 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 in a relatively low rpm range for fuel conservation while yielding adequate tractive force by depressing the Shift mode selection switch accelerator pedal. High Performance SAA6D125E-5 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. Net: 223 kW 299 HP Low Emission Engine This engine meets EPA Tier 3 emission regulations and EU Stage 3A emission regulations, without sacrificing power or machine productivity. Lock-up Torque Converter (optional) The Komatsu designed lock-up torque converter provides increased production efficiency, reduced cycle times and optimum fuel savings in load & carry or hill-climb operations. This optional feature allows the operator to activate the system on/off with a switch located on the right-side control panel. 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. Dual-Mode Engine Power Select System This wheel loader offers two selectable operating modes-- E and P. [. . . ] In addition, buffer rings are installed to the head side of the all-hydraulic cylinders to lower the load on the rod seals and maximize the reliability. dust seal rod packing nipple EMMS (Equipment Management Monitoring System) Monitor is mounted in front of the operator for easy hose O-ring buffer rings Gull-wing Type Engine Side Doors Open Wide The operator can open and close each gull-wing type engine side door easily with the assistance of a gas spring to perform daily service checks from the ground. viewing, allowing the operator to easily check gauges and warning lights. 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 abnormality occurs, the monitor displays action details on the character display at the bottom center 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 replacement intervals are reached. Trouble data memory function: Monitor stores abnormalities for effective troubleshooting. 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 sheet metal 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. 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. 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 WA480-6 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 WA480-6 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. Low cut-off pressure for truck-loading operations. 1:Cut-off ON/OFF switch 2:Cut-off adjustment switch 3:Fan reverse ON/OFF switch 4:Boom control 5:Bucket control 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 steps are designed like a staircase, so that the operator can get on and off the cab easily. Electronically Controlled Transmission Lever Easy shifting and directional changes with Komatsu two-lever electronic shifting. Change direction or shift gears with a touch of the fingers without removing the shifting hand from the steering wheel. Solid state electronics and conveniently located direction and gear shift controls make this possible. [. . . ] . Center-pin support, semi-floating, 26° total oscillation Reduction gear . .
