PrefaceNotes 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:

• Consult with the worksite manager about safety regulations at the place of use.
• Adhere to safety regulations at the place of use.
• Follow traffic regulations.
• Adhere to valid guidelines provided by insurers (for example, employers’ professional liability insurance companies, accident insurance, etc.).
• Avoid working methods that can endanger safety.
• Follow all intervals specified for recurrent checks and inspections as outlined in this operator’s manual.

1.2. Intended Use of Wheel Loader

The wheel loader is used to pick up, move, and dump the following materials:

• Soil
• Stones
• Broken rocks
• Bulk materials

This applies to a standard machine under normal operating conditions. Special applications are described in a separate options operator’s manual.

To ensure the intended use:

• Adhere to the operator’s manual.
• Follow maintenance intervals.
• Carry out inspection and maintenance tasks.
• Follow the specifications in the technical data.
• When using the machine on public roads, ensure it complies with applicable national regulations.
• Only lift loads with intended working attachments (fork prongs, crane boom), which must be properly fitted and functioning.
• Ensure that machines used underground (for mining and tunnel construction) are fitted with systems to reduce exhaust emissions (such as diesel particulate filters).
• Adhere to the requirements of each individual country 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 the stipulations of the manufacturer of the basic machine.
