User manual KOMATSU WA480-5 BROCHURE

[. . . ] Normal Mode: This mode provides maximum fuel efficiency for most of general loading. 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. [. . . ] 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 hose O-ring buffer rings 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. Sealed DT Connectors Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance and dust resistance. 6 WA480-5 WHEEL LOADER EASY EASY MAINTENANCE MAINTENANCE EMMS (Equipment Management Monitoring System) Monitor is mounted in front of the operator and is tilted for easy view, 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 the loader has any troubles, the monitor displays action details on the character display at the center bottom of the monitor. Controller monitors engine oil level, pressure, coolant temperature, air cleaner clogging, etc. Monitor informs replacement time of oil and filters on LCD when it reaches replacement intervals. Monitor stores abnormalities for effective troubleshooting. 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. 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. Lengthened drive shaft greasing interval: 1, 000 H 4, 000 H Lengthened Maintenance Interval Lengthened engine oil replacement interval: 250 H 500 H 7 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 3rd auto change 1st 1st hold 2nd 3rd 4th 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. Low cut-off pressure for truck-loading operations. 2nd hold Telescopic/Tilt Steering Column The operator can tilt and telescope the steering column 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. 4th auto change kick-down switch to provide a comfortable working position. Fingertip Work Equipment Control Lever 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 tilted forward or rearward and the wrist rest can be adjusted up or down to provide the operator with a variety of comfortable operating positions. Electronically Controlled Transmission Lever Easy shifting and directional changes with Komatsu two-lever electronic shifting. [. . . ] .
