Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and the ventilation slots clean.
The power tool must be serviced by a Würth master
Service after 150 operating hours.
Service Indication
The yellow LED lights up when the carbon brushes
are almost completely worn. After approx. 8 further
operating hours, the brushes will be completely
worn and the motor will shut off automatically.
The red LED lights up when the lock-on button is used
in a different operating mode than chiselling. The
red LED starts to flash when a power tool malfunc-
tion is given, or when the brushes are completely
worn.
If the machine should fail despite the care taken in
manufacturing 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
household waste!
According to the European Directive
2012/19/EU on waste electrical
and electronic equipment and its
incorporation into national law, power tools that are
no longer suitable for use must be separately col-
lected and sent for recovery in an environmen-
tal-friendly manner.

The vibration emission level given in this information
sheet 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 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 differ-
ent accessories or poorly maintained, the vibration
emission 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.
