It can be operated freely between the engine low idle position and
the full throttle position.
GEAR SHIFT LEVER
The gear range can be selected with this lever (3) to match the
travel conditions.
Position D:
This is used when traveling normally. When this position is used,
the transmission is set automatically between the 2nd torque
converter drive and 6th gear according to the travel speed. While
the dump body is raised, however, the transmission is fixed to the

travel. The maximum travel speed in this position is 58.6 km/h
(36.4 MPH).

lever is restricted to the 2nd speed and cannot be shifted in the D
position, when the machine is running while the dump body is not
fully lowered to its seat.

This is used when traveling in reverse. When this position is used, the transmission is fixed in R1 and the travel is
carried out in torque converter drive or direct drive according to the travel speed. The maximum travel speed in this
