1.3 Brief description of the wheel loader

Models and trade names

Use

Due to a wide range of possible attachments, the machine is a versatile and powerful

helper in the construction industry, in agriculture and in recycling operations.

• Possible applications –see“Certified attachments” on page 1-13.

• Retrofit the machine accordingly with specific safety equipment when using it as

a lifting gear – see chapter 2 “Applications with lifting gear” on page 2-8.

Machine licensing

According to German traffic regulations and the German agricultural and forestry tractors

provision (optional registration), thewheel loader is a self-propelled work machine, tractor

or equipment carrier.

The type of machine licensing is specified in the Data Confirmation and Licence Certificate

of the machine.

During machine travel on public roads, the wheel loader must be equipped with lights

(option) and a signalling system (option).

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

Permissible operating temperature range

Notice!

The operating temperature range for a machine serviced in compliance with

the maintenance instructions is −15 to 40 °C during normal operation with

short intervals of operation at maximum output.

Operating temperatures below −15 °C or above 40 °C require special

equipment and/or material (fuel, engine and hydraulic oil).

Please contact your dealer if you require more information on operation in

extreme temperature ranges.

1 Introduction

Main components of wheel loader

• ROPS-tested cabin (standard) or canopy (option)

–see“Cabin number” on page 1-15

➥ROPS is the abbreviation for “Roll Over Protective Structure”

• Water-cooled Yanmar three-cylinder diesel engine

➥23 kW at 2600 rpm (27 kW option)

➥Exhaust emissions according to EC standard 2004/26 EC

• Sturdy steel sheet frame;

➥Rubber-mounted engine and cabin/control stand

• Hydrostatic drive with automatic drive control, inching valve

➥20 kph max. speed

• Hydraulic four-wheel power steering with emergency steering features

• Axle carrier with steered front and rear wheel motors

• Hydrostatic service brake (inching brake)

• Parking and auxiliary brake in front axle wheel motors

➥Spring brake actuator braking system with electro-hydraulic actuation

➥Differential lock (option)

Hydrostatic drive

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

whose oil flow is sent to the wheel motors flanged onto the front and rear axles.

This creates permanent 4 wheel drive.

Operating hydraulics and 4 wheel steering

The variable displacement pump also drives the flanged gear pump for the operating

hydraulics and hydrostatic 4 wheel steering. The oil flow of this pump depends on the diesel

engine speed.

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

gear pump for the operating hydraulics and steering. This is made possible by a so-called

inching valve that responds as soon as the brake/inching pedal 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/inching 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 indicator lights on the instrument panel of the machine indicate whether the engine

and hydraulic oil temperatures are too high.
