Increased engine horsepower
With the increased engine horsepower and low-speed torque, the WA800-3 and WA900-3 have an improved engine response, providing much more powerful penetration and digging.
Using the electronic control governor, the WA700-3 reduces exhaust gas components (clearing the exhaust gas regulations in USA and Europe).

Buffer ring added to hydraulic cylinder Buffer ring has been added to the head side of the hydraulic cylinders. This lowers the load the to rod packing and reduces the oil leakage, thereby improving the reliability and durability even further.
Trouble data display for controller employed On the speedometer of the main monitor, the failure codes and action codes can be displayed, so it is possible to carry out troubleshooting quickly. Moreover it is possible to display the failure codes in order of time occurred for the previous 1000 hours (max. 9 items, and older items are deleted in order).

(Current)
Broken at the neck (single breakage by lateral load)
Crack on welded part (Stress concentrated on the welded part of the cutting edge tip which had a large displacement producing fatigue failure)
(New)
Displacement at cutting Neck reinforced edge tip 0.46 times (FEM) 1.8 times

Kick-down switch for fast, powerful loading When carrying out scooping-up operations of soil, it is possible to shift down from F2 to F1 by pressing the kick-down switch at the top of the boom control lever. This makes it possible to carry out powerful scooping operations. After scooping up the load, when the directional lever is shifted from F to R, the gear is automatically returned to 2nd. This means that there is no need to operate the gear shift lever between 2nd and 1st, thus making it possible to carry out digging and loading operations easily.

' ) ) ( Common to WA600-3 to WA900-3 A push-control panel is used to make it possible to switch at a touch between the 5 modes for the vent positions, thus enabling the operator to select the desired positions for the air flow. The air flow can also be adjusted in 4 stages to provide a comfortable working space. In addition, the cooling capacity and air flow volume have been increased from Dash 1 to provide an even more pleasant working space. 6

Control monitor available (option) A control monitor with display and printer is available as an optional item. Use of the control monitor makes it possible to easily check the vehicle control items (general inspection, maintenance control, and fault diagnosis) using the color display, ensuring safe work. Using the fault diagnostic function, electrical circuits other than those used in the control system are checked. (Fault diagnosis of the control system is made using the main monitor.) Operating data (run-hour and production) can be displayed and printed out, ensuring easy control of production and creation of daily work reports. Additionally, the display can be used as a television set during break.

HARMONY WITH ENVIRONMENT Use of engine which clears the exhaust gas regulations (regulations in USA, Europe) Environment-friendly engine which suppresses NOX, CO, HC, particulate, and other air pollutants to within the strictly regulated range. (WA700-3) Innovative external appearance with smart form and coloring A well-balanced and powerful design employing relaxed coloring with gray on a natural yellow base is used together with a curved design for the large cab and fender to give the machine a rounded appearance. Provision of mud splash prevention cover at lower part of rear access steps An extension cover is provided at the lower part of the rear access steps to prevent mud from splashing around and against the vehicle, proving to be effective for work involving long traveling.

Increased engine horsepower
With the increased engine horsepower and low-speed torque, the WA800-3 and WA900-3 have an improved engine response, providing much more powerful penetration and digging.
Using the electronic control governor, the WA700-3 reduces exhaust gas components (clearing the exhaust gas regulations in USA and Europe).

Buffer ring added to hydraulic cylinder Buffer ring has been added to the head side of the hydraulic cylinders. This lowers the load the to rod packing and reduces the oil leakage, thereby improving the reliability and durability even further.
Trouble data display for controller employed On the speedometer of the main monitor, the failure codes and action codes can be displayed, so it is possible to carry out troubleshooting quickly. Moreover it is possible to display the failure codes in order of time occurred for the previous 1000 hours (max. 9 items, and older items are deleted in order).

WA800-3 WA900-3 Improvement of tooth adapter durability To cope with problems of breakage of the adapter neck, cracking on the welded part observed sometimes at work sites under harsh conditions such as swiveling diagonal collision digging, excavating and handling huge rocks, the size of the tooth adapter and the thickness of the cutting edge plate have been increased to improve the durability.
(Current)
Broken at the neck (single breakage by lateral load)
Crack on welded part (Stress concentrated on the welded part of the cutting edge tip which had a large displacement producing fatigue failure)
(New)
Displacement at cutting Neck reinforced edge tip 0.46 times (FEM) 1.8 times
Stress at welded part 0.55 times (FEM) (Fatigue life approx. 10 times ...the 4th power law)

Kick-down switch for fast, powerful loading When carrying out scooping-up operations of soil, it is possible to shift down from F2 to F1 by pressing the kick-down switch at the top of the boom control lever. This makes it possible to carry out powerful scooping operations. After scooping up the load, when the directional lever is shifted from F to R, the gear is automatically returned to 2nd. This means that there is no need to operate the gear shift lever between 2nd and 1st, thus making it possible to carry out digging and loading operations easily.

Control monitor available (option) A control monitor with display and printer is available as an optional item. Use of the control monitor makes it possible to easily check the vehicle control items (general inspection, maintenance control, and fault diagnosis) using the color display, ensuring safe work. Using the fault diagnostic function, electrical circuits other than those used in the control system are checked. (Fault diagnosis of the control system is made using the main monitor.) Operating data (run-hour and production) can be displayed and printed out, ensuring easy control of production and creation of daily work reports. Additionally, the display can be used as a television set during break.

HARMONY WITH ENVIRONMENT Use of engine which clears the exhaust gas regulations (regulations in USA, Europe) Environment-friendly engine which suppresses NOX, CO, HC, particulate, and other air pollutants to within the strictly regulated range. (WA700-3) Innovative external appearance with smart form and coloring A well-balanced and powerful design employing relaxed coloring with gray on a natural yellow base is used together with a curved design for the large cab and fender to give the machine a rounded appearance. Provision of mud splash prevention cover at lower part of rear access steps An extension cover is provided at the lower part of the rear access steps to prevent mud from splashing around and against the vehicle, proving to be effective for work involving long traveling.
