n when operating a super long working attachment

When using a long reach attachment (super long working attachment with a smaller digging tool), this device allows to limit the working pumps oil flows to a value admissible for all the hydraulic cylinders of the working attachment. Turn the key switch S168 to the right, in po movements of the working attachment.

See the section "Height and inclination adjustable cab (optional equipment)" in this chapter.

When the ignition is switched on, pressing this switch activates the cab roof window wiper. Press this switch wich is on the right control panel.

This unit controls an eventually installed standstill heater for the cab or for other circuits on the uppercarriage. Refer to the special issued operation and maintenance manual of the maker of the additional heater.

By pressing on this touch the indicator integrated in the touch lights up and the second characteristic curve for the proportional function of the left joystick is selected.

3.1.7Display for LIEBHERR particle filter (option)

The particle filter replacing the normal silencer in the exhaust line reduces the hydrocarbon, carbon monoxide and soot particles emissions.

The particle filter regenerates itself if the exhaust temperature is over 250°C, the use of Diesel additive to improve the regeneration is not necessary.

The control unit A175 to monitor the particle filter system. The indications of exhaust back-pressure, Diesel engine RPM. and exhaust gas temperature show the charge conditions of the particle filter. Warning signals are optic and acoustic. The operator can thereby react to possible disturbance cases in the filter system and avoid any imminent damage to the filter and to the Diesel engine.

Use / monitoring of the particle filter system

After turning the igition key to contact position, the LCD display shows "Data Logger ready for use" (or "Datenlogger betriebsbereit").

After starting the Diesel engine, the last consulted menu appears.

The key F is used to change between the LCD display menus.

Hold key F depressed for approx. 2 seconds to change to the next menu.

Following menus could be displayed:

Shows the exhaust gas back pressure - only.

Access and equipment of the cab

(or "Abgasgegendruck (mbar) / Abgastemperature 1 (°C)")

Shows in addition the exhaust gas temperature before the filter (engine side)

(or "Abgasgegendruck (mbar) / Abgastemperature 2 (°C)")

Shows in addition the exhaust gas temperature after the filter (exhaust side)

(or "Abgasgegendruck (mbar) / Drehzahl (U/min)")

Shows in addition the Diesel engine RPM.

Note:

The exhaust temperature must be higher than 250°C for approx. 50% of the overall operating time of the Diesel engine, so to allow the particle filter to work optimal and regenerate itself.

For meaning of the error messages on the display see chapter 4 "Faults and remedies".

3.2Access and equipment of the cab

3.2.1Entering or leaving the cab

Climbing up

Caution!

Entering or leaving the cab incorrectly could lead to injury. Proceed with the same attention on exit or entry of the cab, as while climbing the machine.

Ensure that the safety lever is always in its highest position when entering or leaving the cab.

Always use the handholds provided for the purpose when entering or leaving the machine.

Face the machine when getting in or out and always use three-point support, i.e. two hands and one foot or two feet and one hand must always be in contact with the access system at the same time.

Do not hold onto the controls to steady yourself. Never jump from the machine.
