EXPLANATION OF COMPONENTS
TRANSMISSION CUT-OFF SWITCH
When starting the machine off up a hill, turn the transmission cut-off switch to the OFF position, depress the brake pedal, then
gradually depress the accelerator pedal and release the brake slowly to allow the machine to start off. This makes it possible to
prevent the machine from rolling back.
Press this switch (4) to turn on and off the transmission cut-off
system.
When the switch is pressed, the pilot lamp lights up and the system
is turned ON. The transmission is shifted to neutral at the adjusted
brake pedal depression position.
Normally, keep the switch at the ON position.
For details of the method of adjusting the cut-off position, see
"ADJUSTING TRANSMISSION CUT-OFF POSITION (PAGE

switch on the right switch panel.
