This function facilitates the load-and-carry operation.
When the travel speed is higher than 10.5 km/h, each time
the kickdown switch is pressed the gear speed is
shifted down by one gear speed in the order F4, F3, and F2.
REMARK
• To cancel the kickdown, operate the directional lever. In the manual shift mode, the kickdown can also be
canceled by setting the gear speed switch to a position other than the 2nd.
• When the starting switch is turned to OFF position and then to ON position again while the gear speed is
kicked down, the kickdown is canceled.
• Even if the auto-kickdown is enabled, the downshift or the change to P mode with this kickdown switch is
enabled.
• In the auto-shift mode, if the travel speed increases after a kickdown, the gear speed is shifted up automati-
cally.
• In the auto-shift mode, when the travel speed is above 14 km/h in 3rd
gear speed or above 26 km/h in 4th
gear speed, the gear speed is not shifted down to prevent the engine from overrunning even if the kickdown
switch is pressed.
HOLD SWITCH
When HOLD switch
on the top of the lever is pressed to fix the
gear speed in the auto-shift mode, the transmission is fixed to
the gear speed indicated on shift indicator (A) of the machine
monitor and shift hold pilot lamp (B) lights up.
When this switch is pressed again, the shift hold function is
canceled and the pilot lamp goes out.
Use this switch to set the gear speed to any position for uphill
or downhill travel or grading.
REMARK
You can cancel holding by one of the following operations.
• Operation of directional lever
• Operation of gear speed switch
• Operation of setting transmission shift mode selector
switch to MANUAL mode
• Operation of turning starting switch to OFF position
