OPERATING INSTRUCTIONS RH 90 C E Operation Regulating the travelling speed Travelling on level ground Regulate the travelling speed with  pedals (112 and 113, Fig. 2-58:) and  Switch (71, Fig. 2-59:) to the right (slow gear) All forward/reverse travel movements are possible with this gear.  Switch (71, Fig. 2-59:) to the left (fast gear) The excavator can be driven only parallel forwards with this fast gear. The travel gearbox changes automatically into st the 1 gear as soon as another travelling function (e.g. reversing, cornering) is initiated. Change speed range only when the excavator is stationary.

Travelling uphill and downhill Read and observe the "Travelling Safety instructions" chapter.
 Depress padals (112 and 113, Fig. 2-58:) fully to the limit stop. When travelling downhill, the travel retarder valve acts as a speed limiter. The travel retarder valve works correctly if pedals (112 and 113) are fully depressed down to the limit stop. Fig. 2-58:
2-52
Should the travelling speed become too high when travelling downhill release pedals (112 and 113) to stop the excavator.
