Operation

After the diesel engine is started, the speed preselection is set to step 1 (lower idle speed of diesel engine). If preheating of the diesel engine is required, it is set to step 3. If necessary, allow the engine to heat up first. Actuate the mode switch S86. The selected mode is applied together with the associated speed and power. The respective LED is permanently on. In modes E (maximum torque) and P, the diesel engine operates at maximum power. In modes L and F, the hydraulic output is reduced. The selected mode is stored when the engine is shut down, and is indicated by a flashing LED above the switch at the next start-up. Note! The best combination of engine speed and hydraulic power can only be chosen by means of the modes. Changing the engine speed with the arrow keys might not have the desired result. Before starting work, select the mode suitable for the task in hand. Adjusting engine speed with the arrow keys: Increase speed: Press switch S258. Speed is increased by one step. The speed indicator P4 changes accordingly (increasing). Reduce speed: Press switch S229. The speed is reduced by one step. The speed indicator P4 changes accordingly (decreasing). A flashing LED above the switch S86 indicates an intermediate step in the selected mode. This indicates that the engine speed does not correspond to the selected mode. Before continuing with the work, adjust the mode.

To be observed after start-up Danger! Risk of asphyxiation from exhaust gases. In confined rooms, do not start the engine unless you have ensured sufficient ventilation. Open doors and windows in the window to provide ample fresh air.

Caution! Risk of injury, if function check is not carried out properly. Run the diesel engine until the engine and hydraulic oils have reached operating temperature. At low oil temperature, the steering responds only slowly. Move the machine to an open space to test the function of the travel and the slewing gear brake. Check the operating devices of the attachment to ensure that they work properly.
