EXPLANATION OF COMPONENTS
5 - 1 position:
These positions are used in places where it is difficult to travel at high speed, or when traveling on soft ground, or
when starting the machine off on a slope when it is loaded. They are also used
when going downhill if it is needed to use the braking force of the engine.
While the dump body is raised, the transmission is fixed to the 1st gear and is not changed. Keep the dump body
lowered during travel.
REMARK
In conformity with the EU safety rule (EN474-6 5.1.3), the gear shift lever is restricted to the 1st speed and cannot
be shifted if it is anywhere between 1 to 5 positions, when the machine is running while the dump body is not fully
lowered to its seat.
The speed ranges for each position are as follows.
Position Speed range
R2 R2nd torque converter - direct
R1 R1st torque converter - direct
D 2nd torque converter - 6th direct
5 1st torque converter - 5th direct
4 1st torque converter - 4th direct
3 1st torque converter - 3rd direct
2 1st torque converter - 2nd direct
1 1st torque converter - 1st direct
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 idle when moving the shift lever from the N position to the
forward or reverse position.
