Operating Instructions
Clamp the workpiece if it does not remain station-
ary due to its own weight.
Do not strain the machine so heavily that it comes
to a standstill.
Grinding and cutting discs become very hot while
working; do not touch until they have cooled.
Maintenance and Cleaning
Before any work on the machine itself, remove the
battery.
Always keep the machine and the ventilation slots
clean.
If the machine should fail despite the care taken in man-
ufacturing and testing, repair should be carried out by
a Würth Master-Service agent.
For all correspondence and spare parts orders, always
include the article number on the type plate of the
machine.
For the current spare parts list of this machine, log into
the Internet under "http://www.wuerth.com/
partsmanager" or ask for a copy at your nearest Würth
branch office.
Disposal
Power tools, accessories and packaging should be
sorted for environmental-friendly recycling.
Only for EC countries:
Do not dispose of power tools into house-
hold waste!
According to the European Directive
2002/96/EC on waste electrical and elec-
tronic equipment and its incorporation into
national law, power tools that are no longer suitable for
use must be separately collected and sent for recovery
in an environmental-friendly manner.
Battery packs/batteries:
Do not dispose of battery packs/batteries into house-
hold waste, water or fire. Battery packs/batteries must
be collected, recycled or disposed of in an environmen-
tally-friendly way.
Only for EC countries:
Defective or dead batteries must be recycled according
to the directive 91/157/EEC.
Warranty
For this Würth tool, we provide a warranty in accord-
ance with statutory/country-specific regulations from
the date of purchase (proof of purchase by invoice or
delivery note). Damage that has occurred will be cor-
rected by replacement or repair.
Damage caused by normal wear, overloading or
improper handling is excluded from the warranty.
Claims can be accepted only when the machine is
presented undisassembled to a Würth branch office,
your Würth sales representative or a customer serv-
ice agent for Würth pessure air and power tools.
Noise/Vibration Information
Measured
values
determined
EN 60 745-1.
Typically, the A-weighted noise levels of the tool are:
Sound pressure level 79 dB (A); Sound power level
90 dB (A). Uncertainty K = 3 dB.
Wear ear protection!
Overall vibrational values (vector sum of three direc-
tions) determined according to EN 60 745.

For other applications such as cut-off grinding or brush-
ing with steel wire brushes, other vibration values may
result.
The vibration emission level given in this information
sheet has been measured in accordance with a stand-
ardised test given in EN 60745 and may be used to
compare one tool with another. It may be used for a
preliminary assessment of the vibrational impact.
The declared vibration emission level represents the
main applications of the power tool. However if the
power tool is used for other applications, with different
accessories or poorly maintained, the vibration emis-
sion may differ. This may significantly increase the
vibrational impact 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 oper-
ator from the effects of vibration such as: Maintain the
power tool and the accessories, keep the hands warm,
organisation of work patterns.
