Storage location
Store the machine after operation at a sealed off, clean and dry location inaccessible to children.
3.6 Safety during the operation of hand machines
Safe working with hand machines
Secure loose workpieces with suitable methods.
While working, as a rule hold the machine on the provided handles with both
hands.
While working, hold the machine in such a way that hand injuries are avoided
when hitting hard objects.
Setting the hand machine down properly

Electric power supply for electrical appliances of class rating II
Note: The rated voltage is indicated on the nameplate of your machine.
The machine may only be connected to an electric power supply with all machine
parts in proper working condition. Take special notice of the following machine
parts:
Plug.
Power cable over the entire length.
The machine may only be connected to an electric power supply whereby the
connector of the grounded conductor (PE) is intact.
Electrical appliances of class rating II have a strengthened or double insulation
(protective insulation). They have no connection to the grounded conductor.
Note: Observe the respective national safety regulations!
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.

5 Description
5.1 Application
A wide selection of easily interchangeable tools is available for drilling holes from
12 to 125 mm 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 as
well as an additional drilling function.
It is driven by a maintenance-free three-phase AC motor.
A frequency converter converts the generated DC voltage to required threephase AC current.
"Chiseling" operating mode
The rotary movement of the three-phase AC 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.

Description EHB 11
22 Operator’s manual
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.
Thumbwheel for pre-selecting speed
Use the thumbwheel to pre-select the speed.
Reducing the speed while in percussion operating mode diminishes the percussion forces as required for removing tiles, for example.
Adjusting lever for chiseling/hammer drilling
The adjusting lever for chiseling/hammer drilling has three positions as listed below. The arrow on the housing and the opposite symbol on the adjusting lever
indicate 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.

8.2 Maintenance work
Work in the workshop
Perform maintenance work in a workshop on a workbench. This has the following
benefits:
Protection of the machine of contamination on the construction site.
A level and clean work surface makes work easier.
There is a better overview over small parts and they are not lost as easily.
Cleaning the machine
1. Clean the ventilation slots with a suitable tool.
2. Wipe the housing with a damp and clean cloth.
3. Free tool of dirt using suitable tools.
WARNING
Electrical voltage.
Injuries from electrocution.
f Remove the plug from the plug receptacle before all work on the machine.

Lubricating the crank mechanism
Only use special lubricants for lubricating.
For further information, refer to chapter Technical Data.
1. Place filled grease gun onto the zerk fitting and operate 5 to 6 times.
2. Wipe off zerk fitting with a clean cloth.
Checking the tool holder for wear
f Measure the tool play 200 mm from insertion point.
Play may not exceed 6 mm.
If the play exceeds 6 mm, the tool holder bushing in the tool holder must be replaced.

EHB 11 Troubleshooting
Operator’s manual 41
9 Troubleshooting
Please refer to the following table if the machine does not work properly. It contains potential faults, their causes and remedies.
Malfunction Cause Remedy
Machine not in operation For machines with 230 V:
Input voltage too high (> 300 V)
or too low (< 80 V).
Provide correct voltage; if necessary use an extension cable
with sufficient cross section.
For machines with 115 V:
Input voltage too high (> 150 V)
or too low (< 45 V).
Provide correct voltage; if necessary use an extension cable
with sufficient cross section.
Inverter has switched off due to
excess temperature.
Let machine cool off.
Power cable interrupted. Check power cable, have it re-
placed if defective. *
* Have the machine repaired by your Wacker Neuson representative.
Blocked percussion system High grease resistance due to
very low temperatures.
Allow machine to warm up in
warm environment (e.g. heated
rooms).
Seizing of moving parts (e.g.
due to prolonged dry running).
Have defective components replaced. *
Drill is stuck/jammed Too much borer dust in bore-
hole.
Pull drill bit out off borehole and
remove dust from drill bit.
Interfering reinforcing steel. Redrill borehole.
