OPERATION
REMARK
When canceling the kick-down, operate the directional lever. In manual shift, the kick-down can be canceled by
operating the gearshift lever to any position other than 2nd. It is also possible to cancel the kick-down by turning
the starting switch OFF.
In auto-shift, if the travel speed becomes high after the kick-down, the gear will be shifted up by the auto-shift.
In auto-shift, when traveling at more than 18 km/h (11.2 MPH) in 3rd or at more than 28 km/h (17.4 MPH) in 4th,
even if the kick-down switch is pressed, the transmission will not shift down. This is to prevent overrun of the
engine.
HOLD SWITCH
To fix the speed range when traveling in automatic transmission,
press switch (15) at the side of the lift arm control lever knob. The
transmission will be fixed in the speed range displayed on shift
indicator (A) on the machine monitor and shift hold pilot lamp (B)
will light up.
When the switch is pressed again, the display goes out.
Use this function to select the desired speed range when traveling
up or down hills or when carrying out operations such as grading.
REMARK
When canceling the shift hold, operate the directional lever or
gearshift lever or operate the transmission shift mode selector
switch to MANUAL. It is also possible to cancel the hold shift by
turning the starting switch OFF.
