Fuel preheating should be switched on at least 5minutes before starting in low outdoor temperatures.
Press switch S213 on the right control panel before starting and with the ignition switched on.
Fuel preheating is switched on. Indicator light in the switch illuminates. Starting the diesel engine.
Note!
Only switch off fuel preheating when the fuel tank has warmed up sufficiently. This may take up to 30minutes at low outdoor temperatures.
Press switch S213 again. Fuel preheating is switched off. Indicator light in the switch goes out.
3.3.5Jump start procedure
Danger!
When connecting to jump start batteries, old batteries can be subject to increased gas formation.
Wear safety glasses and protective gloves during the jump start procedure and avoid open flames and creating any sparks in the vicinity of the discharged vehicle battery. DANGER OF EXPLOSION!
Only use jump start cables with a sufficient cross section. Always follow the established jump starting procedure.
3.3.5.1Connecting the batteries
First connect the cable to the positive terminal (+) of the discharged battery and then to the positive terminal (+) of the jump start battery.
Connect the second cable to the negative terminal (-) of the discharged battery and then to the negative terminal (-) of the jump start battery.
Start the engine as described above.
Caution!
Before removing the jump start cable, be sure to bring the Diesel engine of the jump started machine into low idle.
For safety reasons, turn on a large user, such aswork headlights, uppercarriage lighting etc. to avoid overvoltage. The electronics could otherwise be damaged.
3.3.5.2Disconnecting the batteries
First remove the cable from the negative terminal (-) of the jump start battery and then from the negative terminal (-) of the discharged battery.
Remove the second cable from the positive terminal (+) of the jump start battery and then from the positive terminal (+) of the discharged battery.
Check the electrical functions of the machine.
For battery care and maintenance, see the chapter "Battery care".
3.3.6Travel operation
Before setting the machine to travel operation, put on the safety belt. For travel operation, the uppercarriage must be positioned in travel position on the undercarriage, i.e. the steering axle (oscillating axle) must be at the front of the machine, the rigid axle at the rear.

Before starting the machine, use your foot to release the retainer (arrow) at the brake pedal 6
Release the parking brake S16
3.3.6.1Shifting gear
The machine is equipped with a 2-speed gear system with shift lock that allows for gear shifting under load.
–1. gear: low travel speed
–2. gear: maximum travel speed can be reached
Switching gear when machine is standing still: Press the switch S42 down. The machine is in first gear. Press the switch S42 up. The machine is in second gear.
Switching gear when machine is in motion:
As the gear is switchable under load, it can be operated during travel. During travel in second gear: Press the switch S42 down. The first gear is preselected. The gear is only switched automatically when the necessary low speed is reached.
During travel in first gear: Press the switch S42 up. The gear is switched immediately. The machine is in second gear.
Selecting creeper gear:
Note!
To shift to creeper gear, the machine should be fully halted or at least slowed down to a very low speed, in order to prevent jerking.
Before travelling or when the machine is in motion, actuate the switch S21 to set the machine to creeper gear.
To deselect the creeper gear, press the switch S21 up.
3.3.6.2Travelling
The direction of travel is selected by pressing the rocker switch S263 on the right joystick.
Danger
There is a risk of injury due to lack of attention: when the uppercarriage is at an angle of 180° to the undercarriage, the travel and steering directions are reversed. Before travelling backwards, ensure that no persons or obstacles are in the path of the machine.
After completion of the travelling movement, set the travel direction switch to its neutral position (0 position).
Travelling forward
Press the rocker switch S263 down a The indicator light for forward travel is on.
Push the travelling pedal 7 slowly down.
Travelling backwards:
Press the rocker switch S263 up b The indicator light for reverse travel is on.
Push the travelling pedal 7 slowly down.
The travelling pedal 7 allows for stepless adjustment of the travel speed.
Adjust the engine speed to the desired travel speed.
Automatic:
If the servo control S35 is switched off (e.g. for on-road travel), the speed is controlled depending on the position of the travel pedal. The engine speed is automatically increased, if this is required.
Manual:
In excavator mode (servo control S35 on), the engine speed must be adjusted manually. Pushing down the travel pedal does not change the speed.
3.3.6.3Travelling on slopes
Caution!
To secure the machine on a slope, it is not sufficient to apply the working brakes (risk of pressure loss due to leakage).
Before leaving the operator's cab and/or when shutting down the machine, always apply the parking brake S16.
Tilt the safety lever upwards.
The machine is equipped with an automatic brake valve that prevents overspeeding of the hydraulic travel drive.
Travelling on slopes of inclination by more than 10%
Caution!
When travelling on slopes with an inclination of more than 10%, there is a risk that the machine is accelerated too quickly when shifted to second gear. On slopes with an inclination of more than 10%, always travel in first gear. Before accessing the slope, halt the machine and shift it to first gear.
3.3.6.4Using Tempomat
The Tempomat allows you to save the current drive pedal position. The travel speed is maintained even if the foot is removed from the pedal.
In excavator mode (servo control S35 on), the Tempomat can be used for forward and reverse travel.
In on-road travel mode (servo control S35 off), the Tempomat can only be used for forward travel.
Set the switch S363 to position 1 The Tempomat is activated. The indicator light in the switch is on. Press down the travel pedal 7 until the desired speed is reached.
