User manual KOMATSU WA470-6 BROCHURE

[. . . ] P Mode: This mode provides maximum power output for hard digging operation or hill climb. Dual mode engine power 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 wasted hydraulic pressure. Minimized waste loss contributes to better fuel economy. New Variable Displacement Piston Pump: The pump delivers only necessary amounts minimizing waste loss. Maximum Dumping Clearance and Reach The long lift arms provide high dumping clearances and maximum dumping reach. [. . . ] (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 WA470-6 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 WA470-6 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. High cut-off pressure for digging operations. 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. 5 4 Telescopic/Tilt Steering Column The operator can tilt and telescope the steering column to provide a comfortable working position. Rear-hinged Full Open Cab Door The cab door hinges are installed to the rear side of the cab providing a large opening angle for the operator to enter and exit. 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. Automatic shifts in ranges two through four keep production high and manual shifting at a minimum. 8 9 WA470-6 W HEEL L OADER DIMENSIONS Measured with 26. 5-25-16PR (L3) tires WHEEL LOADER SPECIFICATIONS ENGINE Model . .
