OPERATION

Travel Speed Selector Switch

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.
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
Hi
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 seconds, the
screen returns to the standard screen.
