OPERATION
EXPLANATION OF COMPONENTS
ADDITIONAL CAR HEATER SWITCH
(If equipped)
Use this switch (15) to turn the heater ON/OFF and to regulate the
air flow (2 stages).
Position (A): ON, low air flow
Position (B): OFF
Position (C): ON, high air flow
RPM SET SWITCH
Use this switch (16) when setting or adjusting the angle of the
accelerator.
Position (A) (push front): SET/ACCEL
If this switch is pushed forward when the accelerator pedal has
been depressed to give the necessary engine speed, the opening
angle of the accelerator at that point is maintained and the RPM
SET pilot lamp on the machine monitor lights up.
Once the accelerator opening angle has been set, if the front of the
switch is pushed, the accelerator opening angle will increase by
approximately 7% each time the switch is pressed.
If the front of the switch is kept pushed, the opening angle will
increase 50% each second.
Position (B) (push back): RESUME/DECEL
Once the accelerator opening angle has been set, if the back of the switch is pushed, the accelerator opening angle
will decrease by approximately 7% each time the switch is pressed.
If the back of the switch is kept pushed, the opening angle will decrease 50% each second.
Once the accelerator opening angle has been set in the Auto mode, if the back of the switch is pushed in the
temporary cancel condition, the accelerator opening angle will be restored to the position before the temporary
cancel.
