Manual gear shift mode
Changing the gear speed used while the machine is traveling
• During forward travel: The gear speed used can be set to
F1 to F3.
• During reverse travel: The gear speed used can be set to
R1 to R3.
UP switch (a): Each time this is pressed, gear speed used goes
up one range.
DOWN switch (b): Each time this is pressed, gear speed used
goes down one range.
REMARK
• If the maximum gear speed has been changed while trav-
eling, return the joystick (steering, directional and gear
shift lever) to NEUTRAL position. The setting is returned to
the maximum gear speed set in the preset mode before
starting to travel (when the transmission has been at NEU-
TRAL).
• The preset cannot be changed during travel.
NOTICE
• Do not move close to the edge of a cliff unnecessarily.
When dropping soil at the edge of a cliff to build an
embankment or landfill, always leave one load and use
the next load to push the previous load over.
• When passing over the top of a slope or when dump-
ing soil from a cliff, there is danger that the load on the
machine will suddenly be reduced and the travel
speed will increase. In this case, depress the decelera-
tor pedal to reduce the travel speed.
• In the manual gear shift mode, when the automatic
downshift is ON, the gear speed is shifted down auto-
matically when a load is applied, but is not shifted up
automatically even when the load is removed.
When the automatic downshift is OFF, the gear speed
should be shifted up and down manually.
Select the Auto Shift Down in the customize mode.
