- 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:
- 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”.
Safety instructions
General safety instructions
1. Familiarise yourself with the operator’s manual before starting up the
machine.
Make sure that you are in possession of additional instructions for any special
equipment installed on your machine, and that you have read and understood
them.
2. Only expressly authorised personnel may operate, service or repair the
machine.
Observe the legal minimum ages.
3. Only trained or instructed personnel may operate the machine. Clearly assign
responsibility for operation, rigging, maintenance and repair work.
4. The operator of the machine must ensure that no persons are in the operating
area of the machine on the basis of a risk assessment conducted in respect of
the operating site.
5. Clearly establish the driver’s responsibilities (also with respect to traffic regulations)
and authorise him to refuse to carry out unsafe instructions from third
parties.
6. Personnel undergoing training and instruction, or who are not yet fully qualified,
may only be allowed to work on the machine under constant supervision
by an experienced person.
7. Now and again, check that your personnel are working safely and are aware of
possible dangers in observance of the operator’s manual.
8. Wear safe working clothes when working on the machine.
Do not wear rings, wristwatches, ties, scarves, unbuttoned jackets, loose
clothing or similar garments, as they can become caught in the machinery and
cause injury.
Certain tasks require: safety glasses, safety boots, hard hats, protective
gloves, reflective vests, ear protection etc.
9. Ask the site manager about any special safety regulations in force on the
construction site.
10. Do not hold onto the steering column, the control panel or the control levers
when getting on or off the machine.
You might inadvertently trigger movements which could lead to accidents.
11. Never jump down from the machine. Use the steps, ladders and platforms
provided for getting on and off.
12. Keep all handles, steps, rails, gangways, platforms and ladders free from oil,
grease, mud snow and ice. This reduces the risk of slipping, tripping up or
falling.
13. Familiarise yourself with the emergency exit through the right cab door and/or
the rear window.
14. Unless there are other instructions, perform maintenance and repair work as
follows:
Procedure:
• Park the machine on firm, level ground and lower the working attachment
to the ground.
• Move all control levers to neutral.
• Turn off the diesel engine and take out the ignition key.
15. Before all work on the hydraulic system, depressurise the hydraulic circuits
and the hydraulic tank as described in the operator’s manual.
16. Lock the working hydraulics to prevent accidental actuation before leaving the
operator’s seat.
