1.3 DESIGNATED USE OF THE SHOVEL
This machine has been manufactured in accordance with
advanced and up-to-date technology standards including recog-
nized safety rules. Nevertheless, its use may constitute a risk to
life and limb of the user or of third parties, or cause damage to the
machine and to other material property.
The machine must only be used in technically perfect condition in
accordance with its designated use and the instructions set out in
the operation manual. Only trained safety-conscious operators
who are fully aware of the risks involved should operate the
machine. Any functional disorders, especially those affecting the
safety of the machine, should, therefore, be rectified immediately.
The hydraulic Shovel is designed exclusively for excavating, i.e.
excavation of bulk material and natural soil structure (e.g. earth,
clay, sand and stones ashore and off-shore). Observe local and
national safety regulations. Special conditions at the worksite
require additional safe working precautions, follow your com-
pany's safety instructions. Short traveling distances for changing
the working site are considered as part of the designated use of
the Shovel.
Using the Shovel for purposes other than those mentioned above
(such as object handling and use as a transport vehicle) is consid-
ered contrary to its designated use. The manufacturer/supplier
cannot be held liable for any damage resulting from such use.
The risk of such misuse lies entirely with the user.
WARNING
Special use of the Shovel beyond its designated use, e.g.
object handling operations, require written agreement from
the manufacturer and retrofitment of the Shovel with respec-
tive safety related equipment before such special applica-
tions are permitted.

1.4 DELIVERY OF THE SHOVEL
The Shovel is being delivered disassembled into its main compo-
nents.
For assembling the Shovel refer to the separate Manual
”Assembly Procedure” in Volume 2 Binder.
WARNING
Personnel entrusted with work on the machine must have
read the Assembly Manual, the Operation,- Lubrication- and
Maintenance Manual and in particular the section on safety
before beginning work. Reading the instructions after work
has begun is too late.
If there are any questions concerning the assembling procedure,
contact your local Service Center.
Prior to first operation, inspect the Shovel thoroughly with the Ser-
vice Engineer responsible for the erection of the machine. Check
all fluid levels according to the Lubrication and Maintenance
Schedule.
Damages and defects caused by incorrect operation and mainte-
nance are not covered by the manufacturers guarantee.
