General Information Safety guidelines

A. Prior and during the performance of tests, adjustments, and repairs, the following guidelines must be followed: Any type of work may only be performed by qualified personnel or under the supervision of such personnel. Qualified personnel are persons who - based on specialized training and experience - have sufficient knowledge in the general area of earthmoving equipment and the specific technology of LIEBHERR machines. They must also have knowledge of all applicable laws and general work protection regulations, accident prevention regulations, guidelines and generally approved rules concerning technology, and be able to evaluate if earthmoving equipment is safe to operate and if the necessary work can performed without endangering themselves or third persons. Never operate a machine with a raised cab or canopy! The machine may only be operated with a lowered and secured cab or canopy. Always adhere to the LIEBHERR adjustment values when performing adjustment work. When performing a Delivery Inspection on a machine, the operator(s) must be trained using a current Operation Manual. The safety guidelines in that manual must be particularly observed and followed as listed. The same safety guidelines must also be observed when performing repair work. On the other hand, there are instances of specific repair and/or maintenance which, in the judgment of qualified personnel, require steps and procedures other than as specified in the safety guidelines. in such event, qualified personnel or individuals performing said work under the supervision of such personnel, should assure that additional safety precautions necessary to insure the safety of those involved in the repair are taken. Such items of repair and/or maintenance include, but are not limited to, the following : - It may be necessary to open the side engine compartment doors while the engine is running for diagnostic and/or component adjustment reasons. In such event, care should be taken to assure that the engine compartment doors are fully secured from unexpected and/or unintended closing during the diagnostic and/or adjustment work effort. Care should also be exercised to assure that there will be no inadvertent or unintended contact of any part of the body with any moving and/or heated parts of the engine. Along these lines, loose clothing, scarves, open jackets, ties and jewelry should be avoided. - It may be necessary for purposes of performing repairs, adjustments and/or troubleshooting to start the engine of the machine and to actuate the travel drive with the cab or canopy tilted. Such should never be done unless the machine has been raised completely off the ground and supported properly and according to all applicable guidelines. However, this procedure can only be performed by a factory certified service mechanic. Following please find the Safety Guidelines as listed in the present Operation Manual. Liebherr reserves the right to update any Operation Manual, including but not limited to the revision or addition of safety guidelines. It is, therefore, strongly recommended to also consult the latest Operation Manual of the machine involved.
