SAFETY FUNCTION
1. Alarm buzzer
If the direction of travel is switched between forward and reverse in area Ill in Fig. 3 (travel speed above 13 km/h and engine speed above 1800 rpm, or travel speed above 14 km/h), the alarm buzzer will sound to prevent damage to the clutch.
2. N priority for directional lever The controller is equipped with an interlock function which always gives the neutral output when the lever is at N.

3. Neutral safety
When the directional lever is at any position other than N, the transmission is set in neutral and the machine does not start even if the starting switch is turned ON. This condition is canceled if the directional lever is returned to the N position. (To prevent unexpected movement of the machine when
the engine is started)

4. Speed lever priority
If the speed lever is shifted down when traveling downhill, the transmission is shifted down immediately to make use of the braking force of the engine.
5. Manual shift
If there should be any disconnection in the travel speed sensor or any other failure, and the input of the travel speed stops, the lever operation changes to manual shift.
