User manual KOMATSU WA250PZ-6 BROCHURE

[. . . ] As the machine moves and gains ground speed, the torque demand decreases and the low speed motor is effectively removed from the drive system by a clutch. At this point, the flow is going to the high-speed motor and the low-speed motor is not causing a drag on the system. An inching pedal gives the operator excellent simultaneous control of his travel and equipment hydraulic speeds. By depressing the inching pedal, drive pump flow to the motors will decrease, reducing ground speed and allowing the operator to use his accelerator to increase flow to his equipment hydraulics.

Komatsu loaders are manufactured with an integrated production system under a strict quality control system. Front axle Transfer case Rear axle Engine EASY MAINTENANCE WA380-6 High-rigidity Frames and Loader Linkage The front and rear frames and the loader linkage have got more torsional rigidity to provide resistance increased to stresses. Frame and loader linkage are designed to accommodate actual working loads, and simulated computer testing proves its strength. Wet multi-disc brakes and fully hydraulic braking system mean lower maintenance costs and higher reliability. Brakes require no adjustments for wear, meaning even lower maintenance. The parking brake is also an adjustment-free, wet multi-disc for high reliability and long life. Added reliability is designed into the braking system by the use of two independent hydraulic circuits, providing hydraulic backup should one of the circuits fail. Fully hydraulic brakes mean no air system to bleed, and no condensation of water in the system that can lead to contamination, corrosion, and freezing. nipple Photo may include optional equipment. Flat Face-to-Face O-Ring Seals Flat face-to-face O-ring seals are used to securely seal hydraulic hose connections. hose O-ring EMMS (Equipment Management Monitoring System) Monitor is mounted in front of the operator 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 an abnormality occurs, the monitor displays action details on the character display at the center bottom of the monitor. Monitor function: Controller monitors engine oil pressure, coolant temperature, air cleaner clogging, etc. If the controller finds abnormalities, the error is displayed on the LCD. Replacement time notice function: Monitor informs replacement time of oil and filters on the LCD when replacement intervals are reached. Trouble data memory function: 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. 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. 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, pressurized, and comfortable operating environment. Pillar-less Large Cab 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 front mounted air conditioner was introduced to increase seat reclining and backward slide adjustment. Rear-hinged Full Open Cab Doors Entry and exit into the new komatsu cab starts with sloped staircase type steps and large diameter handrails for added comfort. The large cab doors are rear-hinged to open fully offering easy entry/exit and will not hamper visibility when operating the machine with the doors latched open. Easy-to-operate Loader Control Mono-lever A new mono-lever using PPC (Proportional Pressure Control) allows the operator to easily operate the work equipment, to reduce operator fatigue and to increase controllability. The adjustable wrist rest provides the operator with a variety of comfortable operating positions. Right-side control panel The operator can select the speed range, maximum travel speed in 1st, tractive effort. 4 6 1 5 7 2 1:Speed range selector switch 2:Variable shift switch 3:Traction control switch 4:Max. traction switch 5:Fan reverse switch 6:Quick coupler lock switch 7:2 mode bucket leveler switch 3 Photo may include optional equipment. 8 9 WA200PZ-6/WA250PZ-6 W HEEL L OADER WITH P ARALLEL Z BAR L INKAGE WHEEL LOADER WITH PARALLEL Z BAR LINKAGE WA200PZ-6 WA380-6 WA250PZ-6 SPECIFICATIONS WA200PZ-6 ENGINE Model . .
