Control, 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.

3.3.3.8To 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.

3.3.4Switching off diesel engine

Caution!

The diesel engine and turbo charger might be damaged by incorrect switching off. Do not suddenly shut down the engine from full-load speed.

First reduce the engine speed to lower idle speed by pressing the arrow key S229 As a result only the LED to the very left in the indicator P4 remains on (engine speed).

Let the diesel engine run for minimum 2 to 3 minutes in idle mode. Turn the ignition key to position 0 to shut down the engine. Remove the ignition key.

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".

3.3.6Horizontal alignment of the machine

3-58 Circular spirit level

The machine is most stable when it is in a horizontal position. The greater the inclination, the lower the stability. For this reason, the angle of inclination for travelling and working is limited.

The angle of inclination is monitored by a circular spirit level installed in the foot room of the operator's cab. If the machine is in a horizontal position, the air bubble is in the centre of the in the liquid in the spirit level. The greater the angle of inclination, the closer the air bubble moves towards the edge of the spirit level.

For machine operation, place it on a level firm surface with no or only minimum slope.

Position the machine in such a way that the air bubble in the circular spirit level is as near as possible to the centre (angle of inclination 0°).

Do not exceed the maximum admissible angle of inclination.

Machine operationMaximum admissible angle of inclination [°]

3.3.7Travel operation

3.3.7.1Travelling straight ahead

A Idler

1a/b Left travel pedal

Caution!

Risk of accident!

B Travel drive

2a/b Right travel pedal

For forward travelling, ensure that the front idler A is located at the front of the machine and the travel drive B is at the rear of the machine. Check the travel path to ensure that it is not obstructed and can be travelled safely.

Forward travel:

Push both pedals forward (1a and 2a).

Reverse travel: Push both pedals down (1b and 2b).

3.3.7.2Turning at standstill

Turning left (1):

Push the left pedal down (1b).

Simultaneously push the right pedal forward (2a).

Turning right (2): Push the right pedal down (2b).

Simultaneously push the left pedal forward (1a).

Note!

In order to protect the drives against excessive wear, turning at standstill should be avoided, if possible.

3.3.7.3Turning machine with one chain

Turning left (1): Push the right pedal forward (2a).

Turning right (2): Push the left pedal forward (1a). During travel, applying different forces to the two pedals results in a change of direction.

3.3.7.4Manually steering travel gear

For particularly accurate manoeuvring, the travel gear must be steered manually. Attach the supplied manual levers (1 and 2) to the travel gear pedals. The travel gear can now be steered by hand.

3.3.7.5Speed regulation

The max. achievable travel speed is set with the switch S21. The machine features two speed steps:

Normal travel (position 1):

Maximum drawing pull at moderate speed. Fast travel (position 2): Reduced drawing pull at maximum speed.

Press the switch S21. Switching over from normal to fast travel is activated. LED 1 in the switch is on.

During travel, the system automatically switches between normal and fast travel, provided that the ground conditions permit this (LED 2 is on). On difficult terrain, the system switches back to normal travel and LED 2 is off.

Press the switch S21 again. The switchover function is deactivated. LED 1 in the switch is off.

When the switchover function is deactivated, the machine can only be operated in normal travel mode.

3.3.7.6Braking

Caution!

Quick release of the travel pedals causes the machine to come to an abrupt halt. The operator might find it difficult to remain seated in the cab. The machine might vibrate or swing! There is thus an increased risk of accidents!

Prior to starting the machine, put on the seat belt. If possible, avoid quick braking manoeuvres.

Applying hydraulic brake:

The hydrostatic travel drive acts as a working brake. Slowly release the travel pedals. The pedals automatically return to their neutral positions. The travel drive is stopped, and the machine is slowed down.

When travelling on slopes, the brake valves prevent excessive acceleration of the machine. They thus ensure that the permissible travel speed is not exceeded.

Applying mechanical brake:

When the travel pedals are in neutral position, the machine is secured and cannot roll away. Approximately five seconds after the pedals have been released, the parking brake is applied automatically. The working attachment can still be moved.

Applying parking brake:

If the parking brake is to be applied before this happens automatically, press the switch S354 (SF).

Press the switch SF The LED in the switch is on. The parking brake is applied.

Press the switch SF again. The LED in the switch is off. The parking brake is released.

While working with the machine, the parking brake must be released.

3.3.8Operating instructions for travel gear

Note!

Non-compliance with the instructions below might void the warranty.

3.3.8.1Running in

New travel gears must be run in. The travelling behaviour over the first metres affects the quality of the moving travel gear parts and reduces subsequent wear. Correct running in improves the running performance.

During the first travelling operation, start the machine with great care and accelerate it only slowly.

During the first operating hours, travel only at slow speeds and avoid long journeys.

3.3.8.2Travel gear

The service life of the travel gear depends primarily on the operating conditions. Frequent travelling and working on uneven ground results in increased wear and can cause additional maintenance expenses.

As a rule, travelling operation of the machine should be kept to a minimum. Ideally, travelling operation should not exceed 5% per operating hour. Avoid travelling over long distances and turning at small turning angles.

3.3.8.3Long distance

For the purpose of this machine, a "long distance" is

Tion Of More Than 3 Minutes

When travelling long distances, the temperature in the travel gear is significantly increased, which results in a higher wear of the moving parts.

To prevent overheating of the travel gear, the machine should not travel more than 200m per operating hour.

If the machine must be moved across a longer travelling distance, monitor the temperature of the drive components. We recommend employing an assistant to operate a thermometer.

If the temperature of a moving part of the travel gear (drive, chains, support rollers) exceeds the ambient temperature by more than 20°C, abort the travelling operation. Continue the journey only after the parts have cooled down sufficiently.

Alternatively, you might consider taking measures that prevent overheating of the travel gear or speed up the cooling of the parts, such as spraying the travel gear with water. To do this, we recommend keeping a large volume of water ready on the site (for example in a tanker).

3.3.9Travel alarm system (optional equipment)

Actuate the travel pedal 1 or 2 The travel alarm system is automatically switched on. An acoustic signal (warning signal) is generated.

Deactivating the travel alarm system: Press the button S6R at the right joystick. The travel alarm system is switched off.

Note!

The travel alarm system can be switched off earliest 10 seconds after travel start. If a travel pedal is actuated again, the travel alarm system is reactivated.
