DISASSEMBLY AND ASSEMBLY
KOMATSU Dump Truck  HM400-1

This section explains the order to be followed when removing, installing, disassembling or assembling each component, as well as precautions to be taken for these operations.

Braking mode:
The shift-down point and the shift-up point are both raised, the engine speed is maintained at a higher level, and the amount of cooling oil for the retarder is ensured to provide greater effect when the engine is used as a brake.
Coasting mode:
The shift-down point and the shift-up point become close to each other to decrease the occurrences of unnecessarily shifting transmission.
Power mode:
The power mode uses the power of the machine to provide the maximum payload. However, when the machine is unloaded or has only a light load (high acceleration), an acceleration sensitive type variable shifting point is used. This detects the acceleration of the machine and shifts the transmission up sooner to provide better acceleration and to improve the fuel consumption, noise, and transmission shock.
Economy mode:
When the machine is being used under light load, such as when traveling unloaded or on flat ground, the shift-up point and shift-down point are both lowered, the engine speed is maintained at a lower level, and the fuel consumption, noise, and transmission shock are improved. In this mode, the maximum engine output is limited.
