Assembly
Before any work on the machine itself, pull the mains
plug.
Changing the Tool
When changing the application tool, wear protective
gloves. Remove the blade cover 6 for extra-sharp
blades only for working. Danger of injury when touching
the sharp-edged application tools.
Inserting (see figure A)
For selection of the application tools, see "Recommendations
for Application Tools", page 12.
Press and hold the tool-lock button 5. With the working edge
facing downward, insert the application tool (e. g. blade 1) to
the stop into the tool holder 2 as shown in the figure.
Release the tool-lock button 5. Pull the application tool out of
the tool holder 2, until it can be heard to engage.
Check the tight seating of the application tool/accesso-
ry. Incorrect or not securely fastened application tools/ac-
cessories can come loose during operation and pose a haz-
ard.
For extra-sharp blades, do not remove the blade cover 6 until
now.
Removing
Mount the blade cover 6 before removing extra-sharp blades.
To remove the application tool, press the tool-lock button 5
and pull out the application tool.
Clean the shank end of the application tool each time after re-
moving it.
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-treat-
ment additives (chromate, wood preservative). Materials
containing 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
materials to be worked.

Operation
Starting Operation
Observe correct mains voltage! The voltage of the pow-
er 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 switch on the power tool, push the On/Off switch 4 to po-
sition "1", "2" or "3", depending on the desired stroke rate.
To switch off the power tool, push the On/Off switch 4 back
to the "0" position.
When not using the power tool, switch it off in order to save
energy.
Presetting the Stroke Rate
With the On/Off switch 4, you can preselect three settings for
the required stroke rate. Push the On/Off switch to the de-
sired position.
Setting 1 Low stroke rate: For detailed work requiring pre-
cision
Setting 2 Medium stroke rate
Setting 3 High stroke rate: For high material removal
The required stroke rate is dependent on the material and the
working conditions and can be determined by a practical trial.
Always start with the lowest setting. When the removal rate is
too low, select the next higher setting.
Working Advice
Never work towards your body. While working, ensure
other persons are not in the working range. Danger of
injury from the sharp-edged application tools.
Fig. B: Hold the machine with both hands as shown in the fig-
ure, and do not position or place the hands directly in front of
the working area.
Guide the application tool to the location where material is to
be removed. Start at a flat angle and with low application
pressure. When the application pressure is too high, the
structural surface (e.g., wood, plaster) can become dam-
aged.
The stroke motion of the application tool is actuated through
the pressure applied on the workpiece. This allows for exact
positioning of the application tool at the location where mate-
rial is to be removed.
Note: The machine and the application tools heat up after
prolonged use. Do not overload the machine and allow it to
cool down between individual work steps.
Recommendations for Application Tools
The choice of the optimal application tool (accessory) de-
pends on the application area and must be determined by trial
on the respective workpiece.
