1.1 Important Operator Information
Store the Operator's Manual in the storage compartment behind the seat.
This Operator's Manual contains important information on how to work safely, correctly
and economically with the machine. This Operator's Manual provides information and
instructions for all operators regardless of experience. It helps to avoid risky situations 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. Thoroughly read and understand the information in this
Operator's Manual before operating the machine for the first time. This Operator's Manual
will help to familiarize yourself more easily with the machine, thereby enabling you to use it
more safely and efficiently.
Before operating this machine for the first time, carefully read the section "Safety Instruc-
tions" to learn how to operate the machine safely.
Important
Careful and prudent working is the best way to avoid accidents.
• Instructions are provided for bucket attachments. No instructions are provided for other
attachments. Refer to the specific attachment operator's manual for safe operation.
• Wacker Neuson reserves the right to make product improvement changes during the
course of series production of this machine.
• Modifying the manufacturer specification and configuration of this machine, or using
unapproved attachments, can cause personal hazards and damage the machine.
Contact your Wacker Neuson dealer for additional information and clarification
regarding modifications.
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.
• We reserve 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.
Your Wacker Neuson dealer will be pleased to answer any further questions regarding the
machine or the Operator's Manual.

Introduction
1.3 Brief description
The Wacker Neuson Model 9503WD is a rubber tired self propelled hydraulic excavator.
Before operating the excavator, read the instruction manual, understand the instruction
and practice operation until confident of operating familiarity and competence. Know and
comply with regulations for operation and use of the excavator on the worksite or traveling
on public roads. This excavator is intended for use as an earth-moving machine. Attach-
ments described in Chapter 1.4 “Fields Of Application of Attachments” are approved to
expand the utility of the 9503WD as an earth-moving machine. Do not use any other
attachments with the excavator. Contact the Wacker Neuson dealer for attachment advice
for equipment not described in 1.4.
Major excavator assemblies are:
• Rotating upper structure.
• Undercarriage supporting the upper structure.
• Propulsion system consisting of wheels, axles, brakes and motor for machine
mobility.
• Earthmoving structures (boom, stick and bucket).
The upper structure consists of the following major components or systems:
• Diesel engine/ pump drive.
• Pressure compensated hydraulic system.
• Operator compartment.
• Control systems for work and machine propulsion.
• Swing bearing and hydraulic coupling for upper and lower structure connection.
• Swing gear box and motor.
• Boom mounting points.
• Fuel and hydraulic oil tanks.
• Counterweight.
• Engine and component enclosure.
The lower structure supports the upper structure through a large bearing permitting 360
degree continuous rotation:
• Welded structure.
• Large support bearing.
• Stabilizers.
•Axles.
• Wheels.
• Drive motor.
• Brake system.
Hydraulic systems are supplied power from pumps mounted to a drive box bolted to the
diesel engine. The system is pressure compensated automatically adjusting speed and
force to the working conditions and engine power. The following functions are hydraulically
actuated:
• Upper structure rotation.
• Excavator mobility.
• Steering during excavator movement on the worksite or public roads.
• Stabilizer extension and retraction.
• Boom vertical movement.
• Stick movement in and out.
• Auxiliary hydraulics for attachments.
• Excavator propulsion brakes/park brake.
BA 9503 US – Edition 3.0 *9503b110.fm 1-5
Introduction
• Optional horizontal boom slewing motion.
The diesel engine speed will automatically reduce to the low idle setting if the work cycle is
interrupted for a few seconds to reduce fuel consumption, noise and exhaust emissions.
Movement of a control lever will restore engine speed to the high idle setting in preparation
for work.
Travelling drive
The diesel engine permanently drives the twin axial variable displacement pump whose oil
flow is sent to a hydraulic motor.
Operating hydraulics
The diesel engine also drives the joint gear pump for the operating hydraulics. The oil flow
of this pump depends on the diesel engine speed only.
Cooling system
The indicator lights in the instrument panel of the machine ensure constant monitoring of
the engine and hydraulic oil temperature, as well as of the coolant temperature and level.
Cab (ROPS and FOPS)
The cab has been specially designed for protection in case of an accident.
• ROPS (Roll Over Protective Structure) tested cab
• FOPS (Falling Object Protective Structure) – option
Do not modify or attempt to repair the ROPS cab or ROPS structure. Any permanent
deflection of the ROPS is a failure mode and the cab or structure must be replaced to
ensure future protection to the operator space in the event of a tipping incident. Contact a
Wacker Neuson dealer for instruction or clarification.
The ROPS is a special safety device designed and produced to exacting material and
assembly standards for certification. Bending, heating, welding, cutting, or drilling holes in
the ROPS will reduce the protection performance in a tipping incident.
Fasten your seat belt, otherwise you can be thrown around or even outside the cab and
crushed. Therefore always fasten your seat belt as you drive and work with the machine.
Tighten the seat belt before starting work with the machine.
1.4 Fields Of Application of Attachments
The attachments will decide in the first place how the excavator is used.
NOTICE
In order to avoid damage to the machine, only the attachments listed below
have been certified for installation on the machine.
• Contact your Wacker Neuson dealer if you wish to use other attachments.
Using tools of other manufacturers, or tools which have been released for other excavator
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 staff.
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.
