1 Introduction

1.1 Important information on this Operator's Manual

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 operators, but it also

serves as a reference for experienced ones. It helps to avoid dangerous 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 and the service booklet 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. Therefore, carefully read and understand this Operator's

Manual before operating the machine for the first time. The 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 the machine, carefully read chapter “Safety Instructions” as well, in

order to be prepared for possibly hazardous situations. As a rule, keep the following in

mind:

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 (see service booklet). Always have a technician with

appropriate training or an authorized service center perform the maintenance and repair

work which are not included in this Operator's Manual. Insist on using original spare parts

when performing maintenance and repair work. This ensures operational safety and readi-

ness of your machine, and maintains its value.

Your Wacker Neuson dealer will be pleased to answer any further questions regarding the

machine or the Operator's Manual.

1.3 Models and trade names: overview

1.4 Brief description of the wheel loader

The wheel loader is a self-propelled work machine according to German traffic regulations.

Get informed on and follow the legal regulations of your country.

This machine is a versatile and powerful tool for moving earth, gravel and debris on con-

struction sites and elsewhere.

The wide range of attachments accounts for the numerous applications of the machine: as

a fork lift, a snow plow, a spreader for grit, salt etc., a sweeper or a tree replanter.

See chapter Attachments with certified material densities on page 1-5 for further applica-

tions. Retrofit the machine with appropriate safety features when using it in lifting gear

operation (see section “Applications with lifting gear” in chapter Safety Instructions).

The main components of the machine are:

• ROPS/FOPS tested closed cab

Check number: ROPS 04139-CE (cab without protective screen)

Check number: FOPS 04140-CE (cab with optional protective screen)

• Water-cooled Deutz four-cylinder in-line engine

• Exhaust emissions according to EC standard 2004/26 EC

• Rubber-mounted engine

• Sturdy steel sheet frame

• Automotive drive, infinitely variable hydrostatic axial-piston gearbox;

maximum speed 20 kph / 12.5 mph (30 kph / 18.8 mph option)

• Hydraulic four-wheel power steering with emergency steering features

• Front and rear planetary steering axles, rear axle with oscillation

• Service brake (mechanical and hydrostatic), mechanical disc-type parking brake

Introduction

Hydrostatic drive

The diesel engine permanently drives a hydraulic pump (variable displacement pump),

whose oil flow is sent to a hydraulic motor flanged on the gearbox. The force of the hydrau-

lic motor is transmitted to the rear axle via the transfer gearbox. At the same time, the front

axle is driven by the cardan shaft, ensuring permanent 4 wheel drive.

Work hydraulics and 4 wheel steering

The diesel engine also drives the joint gear pump for work hydraulics and hydrostatic 4

wheel steering. The oil flow of this pump depends on the diesel engine speed only.

When the machine is in operation, the entire diesel engine output can be transmitted to the

gear pump for work hydraulics and steering. This is made possible by an inching valve

which responds as soon as the service brake is used, reducing or cutting off power input of

the drive. Therefore, engine output is fully available for the loader unit by pressing the

accelerator pedal and the brake pedal at the same time.

Cooling system

A combined oil/water radiator (for the diesel engine and the hydraulic oil) is located at the

rear of the machine.

The indicators on the instrument panel of the machine ensure constant monitoring of the

coolant temperature and level, and of the hydraulic oil temperature.
