The specifications apply to a rated voltage [U] of 230 V. These spe-
cifications may vary at different voltages and in country-specific mod-
els.
Values can vary depending on the product, scope of application and
environmental conditions. To find out more, visit

Assembly
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Inserting/changing the saw blade (Accessory)
When fitting or changing the saw blade, wear protect-
u
ive gloves. Blades are sharp and can become hot when
used for prolonged periods of time.
While replacing the saw blade, ensure that the saw
u
blade receptacle is free of material residue, e.g. wood
or metal chips.
Selecting the saw blade
You will find an overview of recommended saw blades at the
end of these operating instructions. Only use saw blades
with a 1/2" universal shank. The saw blade should not be
longer than required for the intended cut.
Inserting the saw blade (see figure A)
Turn the locking sleeve (4) approx. 90° in the direction of
the arrow and hold it firmly. Push the saw blade (1) into the
saw blade receptacle (3). Release the locking sleeve again.
Check that it is seated securely by pulling the saw
u
blade. A loose saw blade can fall out and lead to injuries.
For particular jobs, the saw blade (1) can also be flipped
180° (teeth point upwards) and refitted.
Removing the Saw Blade (see figure B)
Let the saw blade cool down before removing it. There
u
is a risk of injury when touching the hot saw blade.
Turn the locking sleeve (4) approx. 90° in the direction of
the arrow and hold it firmly. Remove the saw blade (1).
Dust/Chip Extraction
Dust 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 dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (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.

Operation
Products that are only sold in AUS and NZ: Use a resid-
u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Starting Operation
Pay attention to the mains voltage. The voltage of the
u
power source must match the voltage specified on the
rating plate of the power tool.
Switching on/off
To switch on the power tool, press the on/off switch (6) and
keep it pressed.
To switch off the power tool, release the on/off switch (6).
Note: For safety reasons, the on/off switch (6) cannot be
locked; it must remain pressed during the entire operation.
Controlling the stroke rate
You can variably adjust the stroke rate of the power tool
when it is on by pressing in the on/off switch (6) to varying
extents.
Applying light pressure to the on/off switch (6) results in a
low stroke rate. Applying increasing pressure to the switch
increases the stroke rate.
The required stroke rate depends on the material and the
working conditions and can be ascertained through practical
tests.
A reduction in the stroke rate is recommended:
– When positioning the saw blade on the workpiece in order
to be able to position the saw blade more precisely,
– When sawing plastic and aluminium to prevent the mater-
ial from melting.
During prolonged periods of use at a low stroke rate, the
power tool may heat up significantly. Remove the saw blade
and let the power tool run at the maximum stroke rate for
around three minutes to cool down.
Working Advice
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Switch the power tool off immediately if the saw blade
u
becomes blocked.
Tips
When sawing lightweight materials, take into account
u
the statutory provisions and recommendations of the
material manufacturers.
Before sawing into wood, chipboard, building materials,
etc., check for any foreign objects such as nails, screws, etc.
and use a suitable saw blade.
Switch on the power tool and guide it towards the workpiece
you wish to work on. Place the base plate (2) on the surface
