Preface
Notes for users
- This service manual is designed for trained specialist staff of the Liebherr organisation and their dealers.
- This service manual contains specialist knowledge for repairing Liebherr construc- tion machines. Basic specialist knowledge on electronics, hydraulics, mechanics and engine technology is not contained in this service manual. Therefore special- ized training and qualifications are necessary. Liebherr recommends participating in the Liebherr training program for construction machines.
In this service manual you will find information on:
— Special tools
— Technical data
— Maintenance intervals and maintenance tasks
— Adjustment procedures
— Structure and function descriptions
— Removal and installation tasks
— Circuit diagrams, hydraulic plans and technical drawings
- You will find information on controls and operation in the operator’s manual. Information on spare parts are in the spare parts catalogue. Please observe the local accident prevention laws.
- You can find information on repairs of machine parts in the service documentation under “Wheel loader – repair instructions”.
Introduction:
Intended Use:
1.1. Laws, Rules, Guidelines and Safety Regulations
To ensure safe operation:
– Ask work site manager for safety regulations at place of use.
– Adhere to safety regulations at place of use.
-Adhere to traffic regulations.
-Adhere to valid guidelines from insurers (for example employers’ professional liability insurance companies, accident insurance et cetera).
-Avoid working methods that can endanger safety.
-Adhere to all intervals specified for recurrent checks and inspections in this
operator’s manual.
Intended use:
Wheel loader is used to pick up, move and dump following materials:
– Soil
– Stones
– Broken rocks
– Bulk materials
This applies to a standard machine in normal operating conditions. Special applications are described in a separate options operator’s manual.
To ensure intended use:
– Adhere to operator’s manual.
– Adhere to maintenance intervals.
– Observe inspection and maintenance tasks.
– Adhere to specifications in the technical data.
– When using machine on public roads, make sure it complies with applicable national regulations.
– Only lift loads with intended working attachments (fork prongs, crane boom), which must be fitted and functioning.
– Make sure that machines used underground (mining and tunnel construction) are fitted with systems to reduce exhaust emissions (such as diesel particulate filters).
– Adhere to individual country’s requirements for underground operation.
– For special uses use special working attachments and if necessary special safety equipment.
– Exclusively mount and use special working attachments with approval and as per stipulations of manufacturer of basic machine.
– Only use approved tyres.
– A suitably equipped workshop is absolutely essential for performing repair work.
