Introduction
1 Introduction
1.1 Important information on this Operator's Manual
Please store the Operator's Manual in the storage box at the rear of 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 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 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 prior to the first drive. This Operator's Manual will help to familiarise yourself more
easily with the machine, thereby enabling you to use it more safely and efficiently.
Prior to the first drive, carefully read chapter βSafety Instructionsβ as well, in order to be
prepared for possible dangerous situations, as it will be too late for it during operation. 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 serv-
ice work is absolutely necessary.
Extensive maintenance and repair work must always be carried out by an expert with
appropriate training. Insist on using original spare parts when carrying out maintenance
and repair work. This ensures operational safety and readiness of your machine, and
maintains its value.
β’ Special equipment and superstructures are not described in this Operator's Manual.
β’ We reserve the right to modify and improve the machine as required by technical
β’ progress without modifying the Operator's Manual.
β’ Modifying Wacker Neuson products and fitting them with additional equipment and
attachments not included in our delivery program requires Wacker Neuson's written
authorisation, otherwise warranty and product liability for possible damage caused by
these modifications shall not be applicable.
β’ 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.

Safety instructions
Applications with lifting gear
Lifting gear applications are procedures involving raising, transporting and lowering loads
with the help of slings and load-securing devices (e.g. ropes, chains).
Applications with lifting gear are basically not allowed. However, the following conditions
must be fulfilled!
Machines in lifting gear applications with a maximum authorised lifting capacity of over
1000 kg (2205 lbs.) or an overturning moment of over 40,000 Nm (29,500 ft. lbs.) must
include the following equipment:
β’ Acoustic or optical warning device β see chapter 3.17 Safe load indicator (option) on
page 3-83
β’ Hose burst valve β see chapter βHose burst valveβ safety feature (option) on page 3-77
Lifting gear applications may be performed with the machine only if the following safety cri-
teria are met:
β’ Proper equipment for slinging and securing the load (load hooks, ropes, chains) must
be available.
β’ The help of an accompanying person is necessary for securing and detaching the
load.
β’ The lift capacity table must be observed in order ensure machine stability before
raising a load β see chapter 6 Specifications on page 6-1.
β’ The load must be secured so as to prevent it from falling or slipping.
β’ Staying under suspended loads, in the danger area or under the machine's
attachment is forbidden.
β’ The machine operator must not raise loads over persons.
β’ Fasten the lifting gear to the work equipment or other parts of the machine so as to
avoid unhooking the sling unintentionally.
β’ Select the mounting position of the lifting gear ensuring the sling is not deflected by
other parts.
β’ Persons guiding the load or securing it must stay in visual contact with the machine
operator! Should this not be possible, ask another person to guide.
β’ Do not use any lifting gear (ropes, chains) which is damaged or not sufficiently dimen-
sioned.
β’ Fasten lifting gear avoiding danger (rotating parts, crushing or shearing) for the
person securing the load. Always wear protective gloves when working with lifting
gear.
β’ The machine operator must guide the load the nearest possible to the ground and
avoid any oscillating or swinging movements!
β’ The machine may be moved with a raised load only if the path of the machine is as
level as possible.
β’ The persons attaching or securing loads may approach the boom from the side only,
and only after the machine operator has given his permission. The machine operator
may give his permission only after the machine is at a standstill and the work
attachment no longer moves!
β’ The machine operator may not leave his seat as long as the load is raised.
β’ Get informed on and follow the legal regulations of your country.
