EH 23, 27 Safety
13
Work recommendations
Please observe the recommendations below:
Work only if you are in a good physical condition.
Work attentively, particularly as you finish.
Do not operate the machine when you are tired.
Carry out all work calmly, circumspectly and carefully.
Never operate the machine under the influence of alcohol, drugs or medica-
tion. This can impair your vision, reactions and your judgment.
Work in a manner that does not endanger others.
Ensure that no persons or animals are within the danger zone.
3.3 Protective gear
Work clothing
Clothing should be appropriate, i.e. should be close-fitting but not restrict your
movement.
When on construction sites, do not wear long hair loosely, loose clothing or jewelry including rings. These objects can easily get caught or be drawn in by moving machine parts.
Only wear clothing made of material that is not easily flammable.
Personal protective gear
Wear personal protective gear to avoid injuries or health hazards:
Non-skid, hard-toed shoes.
Work gloves made of durable material.
Overalls made of durable material.
Hard hat.
Ear protection.
Face protection.
Eye protection.
Breathing protection in the case of dusty ambient air.
Ear protection
This machine generates noise that exceeds the country-specific permissible
noise levels (individual rating level). It may therefore be necessary to wear ear
protection. You can find the exact value in the chapter Technical Data.
When wearing ear protection while working, you must pay attention and exercise
caution because your hearing is limited, e.g. in case someone screams or a signal tone sounds.
Wacker Neuson recommends that you always wear ear protection.

Do not touch any hot parts such as tools, tool holders or guide cylinders during
operation or directly afterwards. These parts can become very hot and can cause
severe burns.
Caution with movable parts
Keep your hands, feet and loose clothing away from moving or rotating machine
parts. Parts of your body being pulled in or crushed can cause serious injuries.
Caution with toxic materials
Some materials may contain toxic chemicals which are released during demolition. Therefore personal protective equipment must be worn to prevent inhalation
of and skin contact with work dust.
Safety EH 23, 27
16
Do not direct towards people
Do not direct the machine towards people in the vicinity during operation. The
tool might be flung out and cause serious injuries.
No persons endangered
Be sure that no persons are endangered by flying or falling materials. Always
work very attentively, and anticipate potential hazards.
Switching off the machine
Switch off the machine and pull the plug out of the plug receptacle in the following
situations:
Before breaks.
If you are not using the machine.
If you are changing the tool.
If you are removing chips or splinters.
Before storing the machine, wait until it has completely stopped running.

IT-net.
Note: Observe the respective national safety regulations!
Safety EH 23, 27
18
Extension cable
The machine may only be operated with undamaged and tested extension cables!
Only use extension cables with grounded conductor and correct connection of
the grounded conductor to the plug and coupling (only for machines of class rating I, see chapter Technical data).
Only use tested extension cables which are suitable for use at construction sites:
Average rubber hose H05RN-F or better – Wacker Neuson recommends
H07RN-F, an SOW cable, or a country-specific equivalent design.
Immediately replace damaged extension cables (e.g. tears in the sheathing) or
loose plugs and couplings.
Cable drums and multiple plug receptacles must fulfill the same requirements as
the extension cable.
Protect extension cables, multiple plug receptacles, cable drums and connection
couplings against rain, snow or any other forms of moisture.
Uncoil the cable drum completely
Danger of fire due to wound cable drum.
Uncoil the cable drum completely before operation.
Protecting the power cable
Do not use the power cable to pull or lift the machine.
Do not unplug the power cable by pulling on the cable.
Protect the power cable from heat, oil and sharp edges.
If the power cable is damaged or the plug is loose, have it replaced immediately
by your Wacker Neuson representative.
Protecting from moisture
Protect the machine against rain, snow or any other forms of moisture. This could
cause damage or other malfunctions.
3.8 Maintenance
Maintenance work
Service and maintenance work must only be carried out to the extent described
in these operating instructions. All other procedures must be performed by your
Wacker Neuson representative.
For further information, refer to chapter Maintenance.
EH 23, 27 Safety
19
Disconnecting the machine from the electric power supply
Before carrying out service or maintenance work, pull the plug out of the plug receptacle in order to disconnect the machine from the electric power supply.
Cleaning
Always keep the machine clean and be sure to clean it each time you have finished using it.
Do not use gasoline or solvents. Danger of explosion!
Do not use high pressure washers. Permeating water can damage the machine.
When electrical equipment is present, this can pose a serious injury risk from
electric shocks.
Cleaning the zerk fitting
Wipe the zerk fitting with a clean cloth after the lubrication of the machine. There
is a danger of electrocution if there is excessive grease on the zerk fitting.

5 Description
5.1 Application
Use the machine only as intended, see chapter Safety, Proper use.
5.2 Functionality
Principle
The machine is a demolition hammer with a pneumatic percussion system.
It is driven by an electric motor.
The rotary movement of the electric motor is converted into a stroke movement
via a transmission and a crank gear.
The piston is moved forwards and backwards by the crank gear, this compresses
the air (forward movement) or generates a partial vacuum (backward movement). Due to change in pressure the percussion piston is moved forward and
backwards (air cushion percussion system) and hits the tool.
The hood and operator's controls are decoupled from the percussion system by
a spring system. This spring system keeps vibrations away from the operator's
body if he for example presses his body against the hood while working.

10 Disposal
10.1 Disposal of waste electrical and electronic equipment
For customers in EU countries
This device is subject to the European Directive 2002/96/EC on waste electrical
and electronic equipment (WEEE) and the corresponding national legislation.
The WEEE directive outlines the procedure for handling electrical waste equipment across the EU.
The device is labelled with the symbol of a crossed out dustbin
shown here. This means you may not dispose of it with normal
household waste but in a separate environmentally-friendly waste
collection.
This device is a professional electrical tool designed for commercial
applications only (B2B device according to WEEE directive). Contrary to equipment used in most private households (B2C devices), in some EU countries such
as Germany, this device may not be disposed of at a collection point in a public
disposal facility (for example at public waste depots). In case of doubt, ask the
sales outlet about the proper disposal procedure for B2B electrical equipment in
your country and ensure you dispose of the device in accordance with the valid
legal guidelines. Please also note any information in the sales contract and the
general terms and conditions from the point of sales.
The proper disposal of this device prevents the occurrence of any negative effects on people or the environment, follows the specific procedures for handling
harmful substances and enables valuable raw materials to be recycled.
For customers in non-EU countries
The proper disposal of this device prevents the occurrence of any negative effects on people or the environment, follows the specific procedures for handling
harmful substances and enables valuable raw materials to be recycled. Therefore, we recommend that this device is disposed of in a separate, environmentally-friendly waste collection and not with normal household waste. In some
cases, national legislation also stipulates the separate disposal of electric and
electronic products. Please ensure you dispose of this device in accordance with
the valid regulations in your country.
