!
 Attention! The tool still runs for a little while after the machine was
switched off.
For further safety instructions, please refer to the enclosure!
Before starting the machine check the correspondence between voltage
and frequency according to the data mentioned on the identification plate.
Voltage differences from + 6 % and –10 % are allowed.
The grinder is made in protection class II.
Only use extension cables with a sufficient cross-section. A cross-section
which is too small could cause a considerable drop in performance and an
overheating of machine and cable. The tool includes a start-up speed
limiter to prevent fast expulsion fuses from unintended responding.
Short-Time Operation
Switching-on: press the on/off switch
Switching-off: release the on/off switch
Permanent Operation ( only by using with floor guiding device )
Switching-on: press the on/off switch and, keeping it pressed, engage the
lock-on button
Switching-off: press the on/off switch and release itagain
Attention!
In case of every stop of the machine or a power cut, the
lock-on button has to be released immediately by pressing
the ON/OFF switch. So you can avoid an unintentional
restart of the machine (physicalhazard).
Dust which occurs during your work is hazardous to health. That is why the
concrete grinder must be used with a vacuum cleaner, and a dust mask
has to be worn. A suitable Wet/Dry Vacuum Cleaner is available as
accessory. It can directly be attached to the connection on the dust hood.
Switch the machine on and put it carefully on the surface you want to work
on. Hold the tool with both hands and work with circular or linear
movements.
For best working results: Don’t put too much pressure on the surface you
want to work on.

Instruction for Use

For grinding works right into edges of the wall one segment of the dust
guard can be removed by means of the chucking device. This allows
grinding on surfaces which are usually hard to reach.
For it loosen both wing screws and pull the segment off (see fig. below).
Attention! All other grinding works have to be done with the complete
closed dust guard.
Attention!
The grinding wheel might heat up enormously during operation. You
could burn your hands or get cut or ripped by the segments.
Therefore, always use protective gloves when changing the grinding
wheel.
Before any work on the tool, disconnect the plug from the mains!
First of all, the detachable hood segment has
to be removed.
For it loosen both wing screws and pull the
segment off.
Through the opening at the protection cover
now you can hold up the driving disc between
gearbox and grinding wheel by using the jaw
wrench 32 included in the delivery.
Use the face spanner to unscrew the driving
nut.
Then remove the mounted grinding wheel
respectively mount the new one.
Changing the Diamond Grinding Wheel

The assembly works the other way round!
After mounting the grinding wheel, let the machine run for a short period of
time and in a safe position. If the machine does not run easily, stop working
immediately.
Use only original accessory!
In order to protect the operator, motor and drill bit, the concrete grinder is
equipped with an electronic and thermal overload protection.
Thermal: In case of permanent overload, a thermocouple protects
the motor against destruction. In this case, the tool
switches off automatically and can only be restarted after a
certain cooling period (approx. 2 minutes). The cooling
period depends on the heating of the motor winding and
the ambient temperature.
Electronic: In case of overload, the electronic facility will deenergize
the tool. After discharge and reengagement one can drill
again.
Before the beginning of maintenance or repair works you
have to disconnect the plug from the mains.
Repairs may be executed only by appropriately qualified and experienced
personnel. After every repair the machine has to be inspected by an
electric specialist.
Due to its design, the machine needs a minimum of care and maintenance.
However, the following points always have to be observed:
 Always keep the power tool and the ventilation slotsclean.
 During work, please pay attention that no particles get insidethe
machine.
 In case of failure, a repair has to be carried out by anauthorised
service workshop.
Raw material recycling instead of waste disposal
To avoid damages on transportation, the power tool has to be delivered in
a sturdy packing. Packaging as well as unit and accessories are made of
recyclable materials and can be disposedaccordingly.
Overload Protection
Care and Maintenance
Environmental Protection

10
The tool’s plastic components are marked according to their material,
which makes it possible to remove environmental friendly and
differentiated because of available collection facilities.
Only for EU countries
Do not dispose of electric tools together with household
waste material!
In observance of the European Directive 2012/19/EU on
waste electrical and electronic equipment and its
implementation in accordance with national law, electric
tools that have reached the end of their life must be
collected separately and returned to an environmentally
compatible recycling facility.
The indication of noise emission is measured according to DIN 45 635, part
21. The level of acoustic pressure on the work place could exceed 85 dB
(A); in this case protection measures must be taken.
Wear ear protectors!
The typical hand-arm vibration is below 2.5 m/s².
Measured values determined according to EN 60 745.
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.
Dust from material such as paint containing lead, some wood species,
minerals and metal may be harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory diseases to the operator or
bystanders.
Noise Emission / Vibration
Dust protection

11
Certain kinds of dust are classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood conditioning
(chromate, wood preservative). Material containing asbestos must only be
treated by specialists.
Where the use of a dust extraction device is possible it shall be used.
To achieve a high level of dust collection, use industrialvacuum cleaner
dust class M for wood and/or minerals together with thistool.
The work place must be well ventilated.
The use of a dust mask of filter class P2 is recommended.
According to our general terms of delivery for business dealings, suppliers
have to provide to companies a warranty period of 12 months for
redhibitory defects (to be documented by invoice or deliverynote).
