Work instructions

A prerequisite for proper maintenance is a flawless and complete basic set of tools and the necessary devices and special tools.

Only use clean and undamaged tools. Replace damaged tools in a timely manner. Cleanliness and order contribute to safety at the workplace.

Clean the diesel engine, in particular connections and screw fittings, of oil, fuel and care products at the start of the repair. Do not use any aggressive cleaning agents. Use lint-free cleaning cloths. Do not use any flammable liquids to clean the diesel engine.

Sealing material (e.g. o-rings, seals, etc.) must always be replaced.

Removed parts should always be checked for their reusability and replaced, if necessary. If no specific torques or tightening instructions are specified, screwed assemblies are to be tightened according to the standard torques; these are included in the “Appendix” section.

Spare parts

Only original LIEBHERR parts or spare parts purchased from LIEBHERR may be used for maintenance of LIEBHERR diesel engines.

LIEBHERR will cancel all possible obligations undertaken by LIEBHERR and/or its dealers, such as guarantee commitments, service agreements etc., without prior notice if parts other than original LIEBHERR parts or spare parts purchased from LIEBHERR are used for maintenance.

All part information in this operator's manual, e.g. identification numbers, thread sizes, dimensions, etc., are only informational. Spare part orders may only be carried out by means of the spare parts catalog pertaining to the scope of delivery.

Lubricating and operating fluids

Only lubricating and operating fluids approved by LIEBHERR may be used for the operation of LIEBHERR diesel engines.

LIEBHERR will cancel all possible obligations undertaken by LIEBHERR and/or its dealers, such as guarantee commitments, service agreements etc., without prior notice if lubricating and operating fluids other than those approved by LIEBHERR are used.

Usage instructions

Illustrations in this operator's manual may have details that differ from your diesel engine. The work concerned should then be performed analogously to the work description at hand.

Improvements that are carried out on the diesel engine may result in changes, which may not yet be mentioned in this operator's manual.

If you require any further explanations or information, the customer service and customer service training departments of LIEBHERR are available to you. The operating instructions are not subject to an updating service. Depending on the technical requirements, the operating instructions are revised and are then published in the current version.
