Auto Retard Speed Control (ARSC)
ARSC allows the operator to simply set the downhill travel speed and go down slopes at a constant speed. This allows the operator to concentrate on steering. The speed can be set at increments of 1 km/h 0. 6 MPH per click (±5 km/h 3. 1 MPH of setting speed adjustment) to match the optimum speed for the slope. The retarder cooling oil temperature is constantly monitored and the descent speed is automatically reduced, if necessary.
Automatic Idling Setting System (AISS)
This system facilitates quick engine warm-up and cab cooling/warming. [. . . ] Hoist times Power Up: 15 sec Power Down: 15 sec
Wet multi-disc brakes and fully hydraulic controlled braking systems realize lower maintenance
costs and higher reliability. Wet disc brakes are fully sealed to keep contaminants out, reducing wear and maintenance. Brakes require no adjustments for wear, meaning even lower maintenance. Service brake and retarder are isolated from the other truck hydraulic functions to ensure reliable performance. The parking brake is a spring applied, oil released, 3 caliper dry disc mounted on the input yoke to the differential. Fully hydraulic braking systems eliminate the air system; air bleeding is not required, and water condensation that can lead to contamination, corrosion, and freezing is eliminated.

DASH-7 FEATURES
Komatsu Components
Komatsu manufactures the torque converter, transmission, hydraulic cylinders, and electrical parts on this dump truck. Komatsu dump trucks are manufactured with an integrated production system under strict quality control system guidelines.
Reliable Hydraulic System
A large capacity oil cooler is installed in each hydraulic circuit, improving the reliability of the hydraulic units during sudden temperature rises. Further, in addition to the main filter, a 10 = 3 (min) line filter is located at the entrance to the transmission control valve. This system helps prevent secondary faults.
High-Rigidity Frame
Front support is integrated with the frame. The frame rigidity has been substantially increased. As a result, flexural rigidity and torsional rigidity, which are indicators of drivability and ride quality, are significantly improved.
Flat Face-to-Face O-Ring Seals
Flat face-to-face O-ring seals are used to securely seal all hydraulic hose connections and to prevent oil leakage.

Sealed DT Connectors Rugged and Durable Dump Body Design
The standard dump body is made of high-tensile-strength steel with a Brinell hardness of 400 for excellent rigidity and reduced maintenance cost. The side and bottom plates of the dump section are reinforced with ribs for added strength. Main harnesses and controller connectors are equipped with sealed DT connectors providing high reliability, water resistance, and dust resistance.
Protection Function Supported by Electronic Control
Item Downshift inhibitor Over-run inhibitor Reverse inhibitor Function
Even if the driver downshifts accidentally, a speed appropriate to the current gear is automatically set, limiting potential over-runs.
When descending grades, if the vehicle's speed surpasses the maximum for the current gear, the front and rear brakes automatically operate, limiting potential over-runs.
The vehicle is prevented from moving backward when operating the body.
Forward/Reverse shift inhibitor This device makes it impossible to shift from forward to reverse when the vehicle's speed surpasses 4 km/hr 2. 5mph. Anti-hunting system Neutral safety
When running near a shift point, smooth automatic shifting takes place. The engine is prevented from starting when the shift lever is not in neutral.
