EXPLANATION OF COMPONENTS EXPLANATION OF COMPONENTS
REMARK
The lever length can be set to 3 levels (positions (A), (B), and (C)).
For adjustment, consult your Komatsu distributor.
(The lever is installed to position (B) when delivered.)
AUTOMATIC SHIFT
Automatic gear shifting can be carried out in the 2nd through 4th
speed range of the four forward and reverse speeds depending on
the travel conditions.
Position (a): 1st
Position (b): 2nd
Position (c): 3rd
Position (d): 4th
The range of speeds during automatic gear shifting is determined
by the position of the gearshift lever as shown in the chart on the
right.
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
10.5 km/h (6.5 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 10.5 km/h (6.5 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).
