When the dump body is raised, the transmission is fixed in 1st or 2nd, and cannot be shifted. Always keep the dump
body lowered when traveling.
When operating the shift lever, be sure to set it in position securely.
If the lever is not placed in position properly, the shift position display on the panel may go out and the transmission
system caution lamp may light up.
Before shifting between forward and reverse, stop the machine completely and then run the engine at low idle.
When starting the engine, if the shift lever is not at the N (neutral) position, the engine will not start.
When the starting switch is at the ON position, if the shift lever is not at the N (neutral) position, the shift lever position
pilot lamp will flash, the central warning lamp will light up, and the alarm buzzer will sound.
If the parking brake is applied or the shift lever is not at the N (neutral) position, the central warning lamp will light
up and the alarm buzzer will sound.
If the shift lever is set to any position other than N (neutral) when the dump lever is at a position other than FLOAT
or the body is still raised, the central warning lamp will light up and the alarm buzzer will sound.
The shift lever must not be returned to the N (neutral) position while traveling.
Release the accelerator pedal and run the engine at low idling when moving the shift lever from the N position to the
forward or reverse position.
When moving the shift lever from the N position to the R1 or R2
position or from the D position to position 5, press the lock button
on the shift lever before operating it.
