When loading or unloading from a trailer, always travel at low speed (with travel speed selector switch
(3) at the Lo position). Never operate travel speed selector switch (3) while loading or unloading.
q
If the travel speed is switched between Hi and Lo when the machine is traveling, the machine may
deviate to one side, even when traveling in a straight line.
Stop the machine before switching the travel speed.
Switch (3) is used to set the travel speed to 3 stages.
Lo lights up : Low-speed travel
Mi lights up : Medium-speed travel
Hi lights up : Hi-speed travel
When the engine is started, the speed is automatically set to
Lo.
Each time that the switch is pressed, the display changes Lo
Mi

Lo in turn.
Even if the travel speed is set to high-speed (Hi) or a mid-range
speed (Mi), when traveling on soft ground or uphill, and travel
power is needed, the system automatically shifts down to low
speed travel (Lo). There is no need to operate the switch. In
this case, the pilot monitor on the monitor display stays lighted
up at Hi (high-speed) or Mi (mid-range speed).
REMARK
Each time travel speed selector switch (3) is switched, the
mode is displayed on the monitor display, and after two sec-
onds, the screen returns to the standard screen.
