The supply oil from main pump (28) flows through lower shutoff valve (27) and swivel (35) to center section of lower main control valve (25). Oil will flow from both travel control spools (23) and (24) to travel motor (16). The pump delivery flow causes rotation of the travel motor. The torque of the travel motors is transmitted to transmission (7). The rotational speed of the travel motor is manipulated by the transmission and also reduced by gear reduction in the wheel drive. The wheel drive increases the torque and the rotational force drives the wheels.

Right joystick control (A) Travel speed control switch (decrease) (B) Travel speed control switch (increase)The travel speed can be adjusted by the slight operation of the travel pedal. The travel speed can also be controlled by the travel speed control switch. The travel speed control switch changes the displacement of the travel motors. The travel speed control switch can be adjusted from the LOWEST SPEED position to the HIGHEST SPEED position. When the travel speed control switch is set at the LOWEST SPEED position, the tortoise appears on the IQAN display monitor. When the tortoise indicator is shown, the percentage of the maximum speed will be displayed below the indicator. When the travel speed control switch is set at the HIGHEST SPEED position, the rabbit appears on the IQAN display monitor.For more information regarding the IQAN Monitor, see Operation and Maintenance Manual, SEBU9201, "Monitoring System -IQAN Monitor".

Operation of travel (36) REVERSE Travel (37) FORWARD Travel (38) Cab (39) Oscillating axle (40) Steer axleThe direction of travel is relative to the position of the lower structure. For normal travel, steer axle (40) is positioned in front of cab (38) and Oscillating Axle (39) to the rear of cab (38). With the machine in the normal position of travel, move the travel pedal forward. The machine will travel in forward direction. This movement is called forward travel (37). When the travel pedal is moved toward the operator, the machine
