Version 001
Extension cable
The machine may only be operated with undamaged 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).
Only use extension cables which are suitable for use at construction sites: Average rubber hose H05RN-F or better – Wacker Neuson recommends H07RN-F
or a country-specific equivalent design.
Immediately replace damaged extension cables (e.g. tears in the sheathing) or
loose plugs and couplings.
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 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.

5.1 Application
EH 6
A wide selection of easily interchangeable tools makes this machine suitable for
breaking, chiseling, digging, puddling, hammering, ramming and deburring
tasks. The machine is suited for processing natural as well as synthetic stone
and asphalt and any type of masonry and concrete.
EHB 7
The wide selection of easily replaced tools makes it possible to drill holes with a
diameter up to max. 90 mm and are also suitable for breaking, chiseling, digging,
puddling, hammering, ramming and deburring. The machine is suited for processing natural as well as synthetic stone and asphalt and any type of masonry
and concrete.
5.2 Functionality
Principle
The machine is a demolition hammer with a pneumatic percussion system. The
machine features an additional drilling function depending on model.
It is driven by an electric motor.
"Chiseling" operating mode
The rotary movement of the electric motor is converted into a stroke movement
via a transmission and a crank gear while in "Chiseling" operating mode.
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.
While in "Chiseling" operating mode, the drill drive is uncoupled via the safety
clutch and the tool holder bushing is fixed in place to prevent turning in the tool
holder.
"Hammer drilling" operating mode
While in "Hammer drilling" operating mode, the rotational movement of the motor
is transferred to the drive shaft of the drill drive via a clutch. The drive shaft uses
gear wheels to turn the tool holder bushing in the tool holder.

Changeover switch
The changeover switch has 2 or 3 operating mode positions depending on machine. The symbol in the viewing window of the changeover switch identifies the
selected operating mode.
While in operating mode "Positioning," it is possible to turn a flat chisel by hand
to achieve the correct working position.
Vibration reduction
The severity of the vibrations are reduced with the vibration reducer.
The vibration reducer makes it possible to handle the machine for a longer period
without becoming fatigued.
ON/OFF switch
A start-up protection is linked with the ON/OFF switch. This start-up protection
has the effect that the percussion rate or speed of the rotary hammer rises slowly
after pressing the ON/OFF switch. The start-up protection prevents or reduces
the chisel from slipping or the drill from jamming.
Depending on model, continuous operation can be set with the ON/OFF switch.

Slide switch for pre-selecting speed
Use the slide switch for the speed pre-selection to set the engine speed.
Two speeds are available.
Reducing the speed while chiseling operating diminishes the percussion forces
as required for removing tiles, for example.
Service light
The service light lights up red shortly before a carbon brush reaches the wearing
limit. Replace carbon brushes in a timely manner.
Plug
The machine comes with a country-specific plug as a standard equipment.
Supplementary handle for EH 6
The supplementary handle ensures a safe work position and reduces operator
fatigue.

12.4 Notes regarding the level of exposure to vibrations
The vibration emission level given in this Operator´s manual has been measured
in accordance with a standardised test given in EN 60745 and may be used to
compare one tool with another. It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents the main applications of the
tool. However if the tool is used for different applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account
the times when the tool is switched off or when it is running but not actually doing
the job. This may significantly reduce the exposure level over the total working
period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.
12.5 Notes regarding class rating
Class rating
The class rating according to DIN EN 61140 specifies the safety measures for
electrical equipment to avoid electrocution. There are four class ratings:
Class rating Meaning
0 No special protection apart from the basic insulation.
No grounded conductor.
Plug connection without grounded conductor contact.
I Connection of all conductive housing components to the
grounded conductor.
Plug connection with grounded conductor contact.
II Reinforced or double insulation (protective insulation).
No connection to the grounded conductor.
Plug connection without grounded conductor contact.
III Equipment is operated on protective low voltage
(< 50 V).
Connection to the grounded conductor is not necessary.
Plug connection without grounded conductor contact.

12.6 Extension cable
A permitted extension cable must fulfill the following criteria:
The extension cable must be undamaged.
The extension cable has to be connected correctly on plug and bushing.
The extension cable has to be suitable for use at construction sites: Average
rubber hose H05RN-F or better – Wacker Neuson recommends H07RN-F or
a country-specific equivalent design.
The extension cable must have been checked by a qualified electrician.
The required cross-section area of a designated extension has been taken
from the table below.
