Shoe slip control 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
In the automatic gear shift mode, if the maximum gear
speed has been changed while traveling, return the joy-
stick (steering, directional and gear shift lever) to NEU-
TRAL 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 NEUTRAL).
The preset cannot be changed during travel.
In the shoe slip control mode, the shoe slip control func-
tions only in gear speed F1.
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 shoe slip control mode, when a load is applied,
the gear speed automatically shifts down, but even
when the load is removed, the gear speed does not au-
tomatically shift up.

WARNING
When switching the travel direction, confirm the safety in
the direction to select.

CAUTION
You can switch the forward/reverse travel direction without
stopping
the machine. However, for the safety, operator
comfort, and service life of the power train, it is recom-
mended not to switch with the engine at full throttle but
depress the decelerator pedal, decrease the engine speed,
and then switch.
