Preface

These operating instructions have been written for the operator and for the maintenance
personnel of the diesel engine.
They contain descriptions of:
– Technical data
– Safety regulations
– Handling and operation
– Maintenance
The operating instructions are to be read carefully and applied before the first
commissioning and later at regular intervals by each person who is assigned to
work with or on the diesel engine.
Work with or on the diesel engine is, for example:
– Handling, care, disposal of operating fluids and auxiliary materials.
– Servicing, including maintenance, inspection.
The operating manual facilitates the operator’s familiarisation with the diesel engine
and prevents faults through incorrect operation.
You will understand that we cannot allow any warranty claims that arise due to
incorrect operation, insufficient maintenance, use of unapproved operating fluids or
non-compliance with safety regulations.
Liebherr will cancel all possible obligations received by Liebherr and/or its dealers,
such as guarantees, service contracts etc., without advance notice if any parts
other than original Liebherr parts or spare parts purchased from Liebherr are used
for maintenance and repairs.
In extreme conditions, more frequent maintenance than scheduled in the inspection
plan can be required.
