User manual KOMATSU WA380-6 BROCHURE

[. . . ] P Mode: This mode provides maximum power output for hard digging operation or hill climb. Fixed Displacement Piston Pump: The pump delivers the maximum amount at any time and the unused flow is disposed. Maximum Dumping Clearance and Reach Pump Valve Quick movement Loss Loss Pump Valve DUM MY Slow movement The long lift arms provide high dumping clearances and maximum dumping reach. The operator can even level loads on the body of a dump truck easily and efficiently. Dumping Clearance: 2885 mm 9'6" Dumping Reach: 1210 mm 4'0" (3. 3 m3 4. 3 yd3 bucket with B. O. C. ) Dual mode engine power selection switch Eco indicator The eco indicator will help an operator to promote energy saving. 4 5 WA380-6 W HEEL L OADER WHEEL LOADER INCREASED RELIABILITY Komatsu Components Komatsu manufactures the engine, torque converter, transmission, hydraulic units, electric parts, and even each bolt on this wheel loader. [. . . ] (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. High cut-off pressure for digging operations. Low cut-off pressure for truck-loading operations. 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 . .
