1 Introduction
1.1 Notices on this Operator’s Manual
The Operator’s Manual is stored in the document box behind the seat.
This Operator’s Manual contains important information on how to work safely, correctly
and economically with the machine. Therefore, it aims not only at new personnel, but it
also serves as a reference for experienced personnel. It helps to avoid dangerous situa-
tions and reduce repair costs and downtimes. Furthermore, the reliability and the service
life of the machine will be increased by following the instructions in the Operator’s Manual.
This is why the Operator’s Manual must always be kept at hand in the machine.
Your own safety, as well as the safety of others, depends to a great extent on how the
machine is moved and operated. Carefully read the Operator’s Manual before putting the
machine into operation. This Operator’s Manual will help to familiarize yourself more easily
with the machine, thereby enabling you to use it more safely and efficiently.
Follow chapter “Safety Instructions” in particular. As a rule, keep the following in mind:
Notice!
Careful and prudent working is the best way to avoid accidents.
Operational safety and readiness of the machine do not only depend on your skill, but also
on maintenance and servicing of the machine. This is why regular maintenance and ser-
vice work is absolutely necessary.
Extensive maintenance and repair work must always be performed by an expert with
appropriate training. Use only original spare parts for repairs. This ensures operational
safety and readiness of your machine, and maintains its value.
• Special equipment and superstructures are not described in this Operator’s Manual.
• Wacker Neuson reserves the right to improve the technical standard of our machines
without adapting the Operator’s Manual.
• Modifying Wacker Neuson products and fitting them with additional equipment and
attachments not included in our delivery program requires Wacker Neuson’s written
authorization, otherwise warranty and product liability for possible damage caused by
these modifications shall not be applicable.
• Subject to modifications and printing errors.

Introduction
Overview of model designations and trade names
1.3 Brief description
The machine model 50Z3/6003 is a self-propelled work machine.
Get informed on and follow the legal regulations of your country.
This machine is a versatile and powerful helper for moving earth, gravel and debris on con-
struction sites and elsewhere. A wide range of attachments accounts for the numerous
applications of the machine, among others hammer and grab applications. When using
these attachments, observe the legal regulations of your country and equip the machine
with all the safety equipment required. See Chapter 1.4 “Fields of application, attach-
ments” for further applications.
The main components of the machine are:
• Travel gear
• Tracked travel gear
• Stabilizer blade
• Live ring
• Upper carriage
•Cab
• Water-cooled diesel engine
• Hydraulic and electrical components
• Boom
Notice!
The machine can be equipped with the “Telematic” option (for transmitting oper-
ating data, location, etc. via satellite)!
Travelling drive
The diesel engine permanently drives a twin axial variable displacement pump whose oil
flow is sent to the control valve. Depending on actuation, each pump supplies a hydraulic
motor or the work hydraulics with oil.
Work hydraulics
The twin axial variable displacement pump supplies the work hydraulics for the main com-
ponents with oil. This pump is output-controlled and supplies the oil quantity depending on
the output required. This machine is also equipped with a gear pump flanged onto the var-
iable displacement pump. Depending on engine speed, this pump supplies oil for the
swivel unit, the stabilizer blade and boom swivelling.
Shock cartridges (option)
The auxiliary hydraulics are equipped with a Schock cartridge to compensate pressure
peaks in the hydraulic system.
Cooling system
The coolant temperature and level is monitored with the indicator lights on the machine’s
instrument panel.

Introduction
1.4 Fields of application, attachments
The attachments will decide in the first place how the machine is used.
Caution!
In order to avoid damage to the machine, only the attachments listed below
have been certified for installation on the machine.
☞Contact an authorized workshop if you wish to use other attachments.
Using attachments of other manufacturers, or attachments which have been released for
other machine types, can reduce the machine’s output and stability considerably, and can
also cause damage to the machine and injuries to the operator or the personnel.
Always compare the weight of the attachment and its maximum payload with the indica-
tions in the lift capacity table. Never exceed the maximum payload stated in the lift capac-
ity table.
Notice!
Please refer to the Operator’s and maintenance manual of the attachment manu-
facturer for using and performing maintenance on attachments such as hammers,
grabs etc.
