REMARK
The 1st position for the gearshift lever fixes the transmission in
1st. There is no automatic shifting of the transmission.
When shifting down from 2nd to 1st, press the kick-down switch
on the lift arm control lever.
If the transmission is in auto-shift and the travel speed is below
12.5 km/h (7.8 MPH) in any speed range when traveling in either
forward or in reverse, the kick-down switch is actuated and
makes it possible to shift down to 1st.
This makes it easy to carry out load and carry operations.
Even if the travel speed is more than 12.5 km/h (7.8 MPH), this
switch can be used to shift the transmission down. Each time
the kick-down switch is pressed, the speed range will shift down
one range at a time (when in 4th: F4 -> F3 -> F2; when in 3rd:
F3 -> F2).
If the torque converter is locked up, the lock-up is cancelled.
To set to the desired speed range when traveling uphill or down-
hill, or when carrying out grading, do as follows.
z When fixing the speed range
Press the HOLD switch on the lift arm control lever.
The speed range is fixed at the speed range displayed on
the transmission indicator on the main monitor.
z
When shifting up or down from set speed range
Shift gear with the gearshift lever.
REMARK
When the transmission has been shifted down from 2nd to 1st
with the kickdown switch, it will shift up from 1st to 2nd when the
travel speed increases.
2. Directional lever
This lever (2) is used to switch the direction of travel of the
machine between forward and reverse.
When starting the engine, if the directional lever is not at the N
position, the engine will not start.
In this case, the central warning lamp will light up and the buzzer
will sound.
Return the gearshift lever to the N position and start the engine.
