WL50

Read and understand the operating instructions in this Man-

ual before operating this wheel loader. Before performing

production work, the operator should nd a remote site to

become familiar with the controls and machine response.

The machine shall be in serviceable condition before at-

tempting to use it as described in the operating instructions.

If the wheel loader is determined not to be in serviceable

condition, notify the site or machine supervisor to have it

repaired before use.

The loader is used to dislodge and load material by moving

the loader forward, taking into account the safety instructions

/ regulations and time periods listed by Wacker Neuson in

the Operator’s Manual. One work cycle consists of picking

up, lifting, transporting and unloading the material.

1.4 Intended use

The loader has been built according to applicable standards

and regulations. Operation by inexperienced persons, or in

an unintended manner, can result in hazards that can lead

to personal risk and subsequent harm to the operator and

persons in the operating area of the wheel loader. Improper

use can damage the wheel loader as well as property in the

vicinity of operation.

Unintended use can endanger the lives of operating

personnel or other persons and cause injuries or

extensive material damage.

BASIC INFORMATION

14

Similar uses of the loader with alternative attachments which

do not change the safety requirements for the loader but

modify the way in which it is used are only acceptable when

attachments that have been expressly approved by Wacker

Neuson are employed. Special conditions apply if you use

optional Wacker Neuson attachments.

The intended operation is described in this Operator’s

Manual. The instructions describe how to operate, main-

tain, inspect and adjust the wheel loader safely. The repair

manual provides additional instruction for safely diagnosing

malfunctions and repairing the wheel loader to maintain

service and performance levels.

The wheel loader shall not be employed for any of the fol-

lowing work activities:

• lifting or transporting people

• using it as a working platform

• using it to lift or transport loads without providing work

equipment for it

• pulling trailer loads

•

operating after the machine has received unauthorized

repairs

• operating with unauthorized modications

2.1 Organizational measures

The following safety instructions are directed at the operator

/ user of the loader.

•

Always keep the Operator’s Manual in the compartment

provided for it.

• As a supplement to the Operator’s Manual, universally

valid legal and other binding regulations relating to road

trafc, compulsory coverage, accident prevention and

environmental protection must be observed, and users

must be instructed to observe them. This applies in par-

ticular to the maximum speed, depending on the model

and the permissible total weight of the loader.

•

If required, instruct that personal protective equipment be

worn. This applies particularly to the handling of harmful

substances at the location of use.

•

Supplement the Operator’s Manual with instructions,

including supervisory and reporting requirements, taking

into account differences between various companies,

e.g. with regard to the organization of work, work pro-

cesses or personnel used.

•

Personnel who have been assigned to operate the loader

must have read the Operator’s Manual before operating

the wheel loader especially the chapter Basic Safety

Instructions.

• Observe all safety messages on the loader and in the

Operator’s Manual.

•

Make sure that all safety messages on the machine

are legible.

•

If the loader becomes unserviceable, stop operating and

inform the supervisor that the wheel loader is not func-

tioning normally. Alternately, contact a trained technician

to diagnose and correct the condition before resuming

operation.

•

No modications shall be made to the wheel loader.

Contact your Wacker Neuson dealer for specic advice

regarding the use of the wheel loader and approved

attachments.

BASIC SAFETY INSTRUCTIONS

18

• If worn or damaged parts need replacement, use only

Wacker Neuson replacement parts to ensure optimum

performance and safety.

• Inspect hydraulic hoses and ttings prior to the start of

each work shift. Correct any observed leaks or abrasion

issues before operating the machine. Extended envi-

ronmental exposure can cause undetectable damage.

Replace hose assemblies periodically as advised in the

maintenance schedule.

•

Thoroughly inspect the wheel loader before each op-

erating shift.

•

The Wheel Loader Repair Manual describes the special

tools, diagnosis techniques, repair sequence proce-

dures, lifting and supporting devices needed to repair this

machine. To avoid unnecessary hazards and possible

damage to the Wheel Loader, do not attempt to repair

this machine without complying with the instructions in

the Repair Manual.

•

Make the location and means of operation of the re

extinguishers known, and consider the options for re

detection and ghting.

•

A Falling Object Protection System (FOPS) is available

for the Wheel Loader Operator Protection System. OSHA

and MSHA require this protection when operating with

overhead hazards. Contact your Wacker Neuson dealer

for advice and availability of a certied FOPS.
