3 Data memory

3 Data memory

A variety of electronic components of the machine contains data memories which save temporarily and permanently technical information on machine condition, events and errors.

This technical information generally documents the condition of a part, module, system or of the environment:

• Operating states of system components (e.g. filling levels)

• Status messages of the machine and its single components (e.g. number of revolutions of wheel, wheel speed, motion delay, lateral acceleration)

• Malfunctions and defects in important system components (e.g. light and brakes)

• Reactions of machine in special driving situations (e.g. actuation of airbag, installing stability control systems)

• Ambient conditions (e.g. temperature)

These data are exclusively of a technical nature. They are used to detect and remedy errors as well as to optimize machine functions. There is no possibility to create motion profiles on driven routes from these data.

If services are used (e.g. repair services, service processes, warranty cases, quality assurance), this technical information can be read out by employees of service network (including manufacturer) from the event and error data memories by means of special diagnostic units.

There you receive further information, if necessary. After the error has been remedied, the information in the error storage is either deleted or continuously overwritten.

When using the machine, situations are possible in which these technical data in connection with other information (accident protocol, damage to the machine, testimonies etc.) could become transferable to people - if applicable in consultation with an expert.

Additional functions regulated by a contractual agreement with the customer (e.g. remote maintenance) permit the transmission of certain machine data from the machine.

Air-cushioned comfort seat

WARNING

Risk of injury due to movement of the machine or machine parts!

When the control lever cannot be moved freely in all directions, it is not possible to execute all functions of the control lever. It may then not be possible to respond quickly and correctly to hazardous situations.

„ After comfort seat, right armrest and steering column have been set, check whether the control lever can be moved freely in all directions.

„ Adapt the setting when the control lever cannot be moved freely in all directions.

WARNING

Risk of injury due to incorrectly set driver's seat!

When the driver's seat is not adjusted individually to the driver, the driver may damage his health due to bad posture while working.

„ Before starting up the machine, adjust the driver's seat ergonomically and individually to the driver.

WARNING

Danger of injury resulting from unintentional movement of machine parts

If the vibration damper has been set too softly, the seat may hit the floor when driving on a bad road and contact with the operating elements is no longer guaranteed. It may then not be possible to respond quickly and correctly to hazardous situations. Thus there is a risk of serious injuries or death.

„ Always set the vibration damper of the comfort seat tightly enough to prevent the seat from hitting the floor even when driving on a bad road.

WARNING

Risk of accident due to brief distraction of the driver

When the driver's seat or steering column is adjusted while driving, the driver cannot pay adequate attention to the travel path. This may result in serious accidents.

„ Adjust the driver's seat and the steering column only when the machine is at a standstill.

PowerSplit

The PowerSplit is used to increase the efficiency of the machine. The continuous engine performance is adjusted to the application conditions and therefore helps to optimise the fuel consumption.

The PowerSplit automatically switches between ECO-Power and M-Power, depending on the speed of the diesel engine.

ECO-Power automatically switches to M-Power if the engine speed drops below 1550 rpm during mowing.

M-Power automatically switches to ECO-Power when the engine speed exceeds 1550 rpm again and the engine load is above the switchover load (factory basic setting 80%).

M-Power always switches back to ECO-Power mode abruptly as soon as the engine is relieved to the necessary extent.

Impact damage protection system

WARNING

Risk of accident due to changed driving behaviour

If the value for the spring on the impact damage protection system is changed, the trigger moment of the impact damage protection system also changes. As a result, the impact damage protection system may trigger in the transport position in case of abrupt loads and the driving behaviour may change. This can lead to accidents.

„ Never change the value for the spring on the impact damage protection system.

The side mounted mowers are equipped with a so-called impact damage protection system in order to prevent damage when driving into obstacles. After the impact damage protection system has been triggered, the side mounted mower swivels back. Reversing the side mounted mower causes the impact damage protection system to engage again.

The trigger moment has been set at the factory.

NOTICE

Damage to the cooling system by using incorrect coolant

If a mixture of coolant containing silicate and a silicate-free coolant is used, this may cause damage to the cooling system of the diesel engine.

„ Never use a mixture of coolant containing silicate and a silicate-free coolant as an engine coolant.

The engine cooling system has been filled with coolant at the factory that ensures frost protection, corrosion protection and further protective effects.

The engine coolant is a mixture of water, anti-corrosion agent and frost protection agent.

The engine coolant has the following properties:

• Heat transfer

• Corrosion protection

• Cavitation protection (protection against pitting)

• Frost protection

• Increase in the boiling point

The engine coolant must remain in the engine cooling system irrespective of the time of year, even in countries which have high outdoor temperatures.

When replacing engine coolant, ensure that

„ The coolant meets the requirements of at least the following specification: LH-01-COL3A.

The engine manufacturer recommends using the anti-corrosion antifreeze Liebherr

Antifreeze OS Concentrate or Liebherr-Antifreeze OS Mix (ready-to-use mixture of 50% water and 50% anti-corrosion antifreeze).

„ that the water which is used meets the requirements of the Drinking Water Guideline of the

World Health Organisation (WHO) of 2006.

„ the engine coolant contains 50% vol. anti-corrosion agent and frost protection agent. This is equivalent to frost protection down to -37° C.

„ the percentage of anti-corrosion agent and frost protection agent in the engine coolant does not exceed 55% vol. This is equivalent to frost protection down to -45° C. Otherwise, the frost protection and the heat supply will deteriorate.

„ the engine coolant is not mixed with a different anti-corrosion agent and frost protection agent.

„ a low coolant level is not topped up not only with water, but also with the correct percentage of an approved anti-corrosion agent and frost protection agent.

Lubricants

To ensure problem-free operation of the central lubrication system, we recommend using the following greases which we have tested. Sodium soap greases must not be used in the on-road or off-road area because of their solubility in water. Grease can be changed from conventional grease to bio-degradable greases (and vice-versa) for the products listed here without resulting disadvantage.

Standard commercial greases or greases recommended by the vehicle or grease manufacturer are used as lubricants. Greases should still exhibit adequate suction and flow performance at –

25 °C (max. flow pressure 700 mbar). They must not have a tendency to bleed out, as this may result in depositions in the lines during extended operation.

MoS2 greases (up to 5% molybdenum disulphide) can be conveyed with progressive pumps and distributor blocks.
