User manual KOMATSU WA430-5 BROCHURE

[. . . ] Power Mode: This mode provides maximum power output for hard digging operation or hill climb. New Dual-Speed Hydraulic System Komatsu's dual-speed hydraulic system increases operational efficiency by matching the hydraulic demands to work conditions. Oil from the switch pump is completely returned to the tank when digging and breaking out, therefore, hydraulic flow to the loader is reduced and pressure is increased. This reduces horsepower demand from the engine and makes the operation more efficient. Kick-down switch signal also controls the oil flow. [. . . ] If controller finds abnormalities, all of these are displayed on LCD. Monitor informs hose O-ring buffer rings replacement time of oil and filters on LCD when it reaches replacement intervals. Monitor stores abnormalities for effective troubleshooting. Reversible Cooling Fan and Swing-out Cooler Elements 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. The coolers can also swing out for easy cleaning. Lengthened drive shaft greasing interval: 1, 000 H 4, 000 H 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. Lengthened Maintenance Interval Lengthened engine oil replacement interval: 250 H 500 H Sealed DT Connectors Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance and dust resistance. 6 7 WA430-5 WHEEL LOADER OPERATOR OPERATOR ENVIRONMENT 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 automatically downshifts from second to first when beginning the digging cycle. It automatically upshifts from first to second when the direction control lever is placed in reverse. This results in increased rim pull for better bucket penetration and reduced cycle times for higher productivity. Hold switch: Auto shift is selected and if the operator turns on this switch when the lever is at the 3rd or 4th gear speed position, the transmission is fixed to that gear speed. 3rd auto change 4th auto change 1st 1st hold 2nd 3rd 4th Comfortable Operation Low-noise Design Operator noise: 72 dB(A) Dynamic noise (outside): 111 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, 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. Variable Transmission Cut-off The operator can adjust the transmission cut-off connected to the left brake pedal with the switch near the operator's seat to set the brake/cut-off point for easier operation and higher operating performance in variable operating conditions. High cut-off pressure for digging operations. Low cut-off pressure for truck-loading operations. low-vibration, dustproof with pressurizing, and comfortable operating environment. Also, spectator noise is lowest in this class. Pillar-less Large Cab (Optional) A wide pillar-less flat glass provides excellent front visibility. 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. Emergency Brake If the brake oil pressure drops, the warning lamp flashes and the warning buzzer sounds intermittently. If the brake pressure drops lower, the parking brake is applied providing a double safety system. 2nd hold Telescopic/Tilt Steering Column The operator can tilt and telescope the steering column kick-down switch to provide a comfortable working position.
