OUTLINE OF GEARSHIFT MODE
There are automatic shift mode and manual shift mode in the gear shift mode. Select the mode to match the
use.
Automatic shift mode
Mode for general dozing work. The speed range is shifted down automatically when the load increases, and
shifted up to the set maximum speed range when the load decreases. This mode is excellent in the fuel econo-
my and the production since the optimum gear speed is selected automatically.
Manual shift mode
A mode for dozing and ripping of rough ground. When the auto shift down is ON, if a load is applied, the speed
range automatically shifts down, but when the load is removed, the speed range does not automatically shift up.
When the automatic downshift is OFF, the speed range must be shifted up and down manually. Select the Auto
Shift Down in the customize mode.
