OPERATION EXPLANATION OF COMPONENTS
3-17
VARIABLE SHIFT MODE
The travel speed can be set in 20 stages from 0.8 km/h to 8.5 km/h.
In particular, the minimum travel speed is set low so that work such as loading the machine onto a trailer or travel-
ing over rough places on the road surface can be carried out more safely.
Furthermore, it is possible to select the optimum travel speed over a wider range for work such as plowing or
winch operations.
q Each time the UP switch on the steering, directional, and
gearshift lever is pressed, two segments on the bar graph
around the outside circumference light up and the set
travel speed increases by approx. 0.4 km/h.
q If the UP switch on the steering, directional, and gearshift
lever is kept pressed, the segments on the bar graph
around the outside circumference light up in turn. When
the switch is released, the speed range is set at that posi-
tion.
q To reduce the set speed, press the DOWN switch on the
steering, directional, and gearshift lever in the same way.
q Direction of travel is displayed at (E) on the speed range
display in the middle and the set travel speed is displayed
on bar graph (G) around the outside circumference.
Nothing is displayed in (F).
(E) F: FORWARD
R: REVERSE
N: Neutral
P: Parking lever is at LOCK position
q When the starting switch is turned from the OFF position to
the ON position, the speed range is set by default to 1st.
q If the mode is shifted from variable shift mode to quick shift
mode, the speed range is set to the nearest speed range
(1st, 2nd, or 3rd).
