Mode selection system (micro computer based electro-hydraulic pump and engine mutual control
system) optimizes the engine and pump performance.
The combination of 3 power modes (P, S, E) and acceleration mode (10 set) of haptic controller
makes it possible to use the engine and pump power more effectively corresponding to the work
conditions from a heavy and great power requesting work to a light and precise work.
