WA700-3

Proven PowerThe field-proven Komatsu six-cylinder,direct-injection turbo-charged SAA6D-170E-3 engine has all the capabilityneeded for today's tough operations.

Reliable Power TrainThe engine, torque converter andtransmission, as well as the hydraulicequipment and electrical parts, under-go strict quality control checks, ensur-ing enhanced reliability and durability.

Durable BucketKomatsu buckets are manufacturedusing high-tensile steel with replace-able welded wear plates for extendedbucket life. Sufficient strength hasbeen incorporated into the bucket bot-tom corners, side edges and spillguard ends for increased durability.

Large Dumping ClearanceThe WA700-3 is designed with ampledumping clearance for dump truckloading.

High Breakout ForceKomatsu wheel loaders use high-ten-sile steel for Z-bar loader linkage togive maximum rigidity, ensuring dura-bility for high breakout force. Sealedloader linkage pins extend greasingintervals.

Excellent StabilityThe WA700-3 has a wide tread3,000mm (9'10") and the longestwheelbase in its class 4,800mm(15'9"), for maximum machine stability.

Smooth ElectronicAutomatic Transmission(Optional)With the electronic automatic trans-mission, you can always enjoy theoptimum speed for the machine condi-tions. Clutch engagement during gearshifting is smooth, so that time lag andshock are small and ride comfort isensured. When ascending ordescending a slope or while operating,the automatic transmission can easilybe set to manual shift by using theswitch.

Roomy, Quiet CabWith Power WindowsThe cab is large, with a spacious inte-rior and power windows. Also, a wideviewing angle is guaranteed becausethe cab is pillarless. By adopting ahigh-capacity air conditioner, Komatsuensures operator comfort, no matterthe exterior conditions. Another fea-tures designed with operators in mindis a lunchbox storage space.

Simple Checks,Easy MaintenanceThe main monitor and the mainte-nance monitor (EDIMOS II) are neatlyarranged on the instrument panel togive a quick, clear reading of machinefunctions at all times. The main moni-tor also has a diagnostic function.

AJSS (Advanced JoystickSteering System)(Optional)

Faster Pile-Penetration& ScoopingA kick-down switch down-shifts thetransmission from forward 2nd to 1stgear for increased rim pull, henceimproved bucket filling. When thedirection control lever is set to reverse,it automatically up-shifts from 1st to2nd gear, reducing cycle time.

Ergonomically-DesignedControlsAll controls are ergonomicallydesigned to minimize operator fatigue.The steering wheel and instrumentpanel are similar to those of a car. Thebucket and boom controls have PPCvalves and short-travel levers toreduce operator effort. With the electri-cally-controlled transmission, directionand gearshift control levers can befinger-operated while holding thesteering wheel with the same hand,allowing instant, positive directionand gearshift changes.

Maintenance monitor

Tiltable Steering Column& One-Glance MonitorsThe steering column can be easily tilt-adjusted to the most comfortable posi-tion with a lever. Together with the two-spoke steering wheel design, this guar-antees better vision of the monitors.

Low Vibration & NoiseThe cab rests on Komatsu viscousdamping mounts (rubber and siliconoil) to reduce vibration and noise. Allhydraulic equipment is mounted onhigh-resistance rubber to furtherreduce vibration and noise.

High-Quality PaintMost exterior plates are treated with acationic electro-deposition undercoatand melamine baked final coating forrust resistance and longer service life.

Maintenance-FreeBraking SystemService brakes employ two hydrauli-cally-actuated independent circuits forincreased safety. The brakes areadjustment-free, fully-sealed, wet discunits, preventing intrusion of dirt anddust. Since the brake system does notuse air, it provides many features suchas absence of condensation, depend-able braking even in cold conditions, noneed for drainage, and rust-free piping.What's more, charging time afterengine starting is drastically shortenedand pedal depressing effort is reduced.

Auto-Greasing System(Optional)The periodic lubrication points, exceptfor the drive shaft, are greased automati-cally according to a preset amount andinterval. Quick-change grease canistersmake replacement easy and clean.

Stair Light (Optional)The stair light, which illuminates therear access stairs for about a minute,is operated by a switch inside the cab,regardless of ignition key position.

Comfortable Operator'sSeatThe operator's seat has a reclining,air suspension desigh with headrestto support the operator comfortablyduring long periods of operation.Also, air suspension makes adjustingthe seat height easy.

The most suitable steering system forwheel loader operation should be bothsmooth and effortless to operate. Withthis in mind, using its hydraulic and elec-tronic control technology, Komatsu hascreated AJSS. This system allows themachine operator to articulate themachine proportionally with the angle ofthe control joystick. He can actuallydevelop a "feel" for the steering articula-tion and thus increase his operation effi-ciency.
