Automatic engine speed setting (option)
The switch is located on the right-hand switch panel.
Diesel engine speed is automatically reduced to idling after 5 seconds if
no hydraulic functions are performed and if the automatic engine speed
setting is enabled.
As soon as a hydraulic function is performed with the control levers/travel
levers, diesel engine speed is automatically increased again to the engine
speed adjusted with the throttle.
5.3 Brakes
Hydraulic brake
Releasing the travel levers/travel pedals brakes the machine.
When traveling downhill, the automatic hydraulic brake valves prevent the
machine from traveling faster than the admissible travel speed.
Reduce travel speed with the travel levers/travel pedals, and not
with the engine speed control of the diesel engine.
Mechanical brake
The stabilizer blade is used as a parking brake. Press the stabilizer blade
against the ground.
