[. . . ] New Variable Displacement Piston Pump: The pump delivers only necessary amounts minimizing waste loss. Dual-Mode Engine Power Select System This wheel loader offers two selectable operating modes-- E and P. The operator can adjust the machine's performance by serect switch. E Mode: This mode provides maximum fuel efficiency for most of general loading. P Mode: This mode provides maximum power output for hard digging operation or hill climb. Maximum Dumping Clearance and Reach Pump Valve Quick movement Feedback Feedback Pump Valve Slow movement DUM MY The long lift arms provide high dumping clearances and maximum dumping reach. [. . . ] 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.

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 PE 2nd PE hold 1st hold 2nd 3rd 4th WA430-6 WA380-6 Comfortable Operation Variable Transmission Cut-off System The operator can continuoucly 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 wiper arm covers a large area to provide great visibility even on rainy days. The cab area is the largest in its class providing maximum space for the operator. Increased seat reclining and slide adjustment to backward by introducing front mounted air conditioner unit. Rear-hinged Full Open Cab Doors 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. [. . . ] .
