Changing the Tool (see figures A–B)
Before any work on the machine itself, pull the
mains plug.
Clean the tool shank
6
and apply a light coat of grease.
Pull out the lock bolt
5
and turn it 180° in anticlockwise direc-
tion. Allow the lock bolt
5
to latch again.
Insert the tool into the tool holder
7
to the stop. The groove of
the tool shank
6
must face upward as shown in the figure.
Pull out the lock bolt
5
and turn it 180° in clockwise direction.
Allow the lock bolt
5
to latch again.
Check the latching by pulling the tool.
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one’s
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dusts, such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
• Provide for good ventilation of the working place.
• It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the mate-
rials to be worked.
Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specified on the nameplate of the machine.
Power tools marked with 230 V can also be
operated with 220 V.
Switching On and Off
To
start
the machine, push the On/Off switch
2
to the “
I
”
position.
To
switch off
the machine, push the On/Off switch
2
to the
“
0
” position.
To save energy, only switch the power tool on when using it.
For low temperatures, the machine reaches the full impact rate
only after a certain time.
This start-up time can be shortened by striking the chisel in the
machine against the floor one time.
Working Advice (see figure C)
While working, hold the power tool with both hands by the
handle
1
. The handle
1
can move upward and downward
around its axis by approx. 30 mm. This has a damping effect
against vibrations.
For the highest possible impact damping, work only with mod-
erate pressure.
Sharpening Chisels
Good results are only achieved with sharp chisels; therefore,
sharpen the chiselling tools in good time. This ensures a long
service life of the tools and good working performance.
Maintenance and Cleaning
Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and ventilation slots clean.
The power tool switches off automatically when the carbon
brushes are used up. The machine must be sent to customer
service for maintenance.
When replacing the power tool’s cable is required, have this
carried out by a Würth master-Service or by an authorised
customer services agent for Würth power tools, in order to
avoid hazardous situations.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
a Würth master-Service.
In all correspondence and spare parts orders, please always
include the article number given on the type plate of the
machine.
The current spare parts list for this power tool can be viewed
in the Internet under
