Shoe slip control mode (if equipped)
Mode for ripping work The shoe slipping is restrained automatically during the ripping work, as a result, the de-
celerator pedal operation can be reduced. Restraining the shoe slipping contributes to improve the service life of
the undercarriage and to reduce the fuel consumption.
If the dozing work is performed in this mode, the setting is automatically changed to that of the manual shift
mode. (In this case, the gear speed display stays the shoe slip control mode.)
When returning to the ripping work, the mode switches to the shoe slip control mode again.
METHOD FOR CHANGING GEARSHIFT MODE
Press the gear shift mode selector switch to switch the mode
while the joystick (steering, directional and gear shift lever) is in
NEUTRAL position.
Every time when the gear shift mode selector switch is press-
ed, the automatic shift mode and manual shift mode are shifted
to each other.
For the machines equipped with shoe slip control, every time
when the gear shift mode selector switch is pressed, the mode
shifts as Automatic gear shift mode → Manual gear shift mode
→ Shoe slip control mode → Automatic gear shift mode in or-
der.
