Inserting/changing the circular saw
blade
English
Remove the battery before carrying out any
u
work on the power tool.
Wear protective gloves when fitting the saw
u
blade. Danger of injury when touching the saw
blade.
Only use saw blades that match the specifica-
u
tions given in this operating manual and that
are tested and marked in accordance with EN
847-1
The permitted speed of the application tool
u
must be at least equal to the maximum speed
marked on the power tool. If accessories run
faster than their rated speed, they may break
and fly off.
Do not use abrasive wheels as the application
u
tool under any circumstances.
Removing the saw blade (see figure A)
To change tools, we recommend that you place
the power tool down on the front side of the mo-
tor housing.
– Press and hold the spindle lock button (6).
Do not press the spindle lock button (6) while
u
the saw spindle is moving. The power tool
may become damaged if this happens.
– Use the hex key (5) to undo the clamping bolt
(25) in rotational direction ➊.
– Swing the retracting blade guard (21) back and
hold on to it firmly.
– Remove the clamping flange (24) and the saw
blade (23) from the saw spindle (20).
Fitting the saw blade (see figure A)
To change tools, we recommend that you place
the power tool down on the front side of the mo-
tor housing.
– Clean the saw blade (23) and all the clamping
elements to be fitted.
– Swing the retracting blade guard (21) back and
hold on to it firmly.
– Place the saw blade (23) on the mounting
flange (22). The cutting direction of the teeth
(direction of the arrow on the saw blade) must
match the rotational direction of the arrow on
the protective guard (21).
– Attach the clamping flange (24) and screw in
the clamping bolt (25) in rotational direction ➋.
Ensure that the mounting flange (22) and
clamping flange (24) are installed in the correct
position.
– Press and hold the spindle lock button (6).

Dust/chip extraction

The dust from materials such as lead paint, cer-
tain types of wood, minerals and metal can be
harmful to human health. Touching or breathing
in this dust can trigger allergic reactions and/or
cause respiratory illnesses in the user or in people
in the near vicinity.
Certain dusts, such as oak or beech dust, are
classified as carcinogenic, especially in conjunc-
tion with wood treatment additives (chromate,
wood preservative). Materials containing asbestos
may only be machined by specialists.
– To achieve a high level of dust extraction, use a
suitable dust extractor together with this power
tool.
– Provide good ventilation at the workplace.
– It is advisable to wear a P2 filter class breathing
mask.
The regulations on the material being machined
that apply in the country of use must be observed.
English
Avoid dust accumulation at the workplace.
u
Dust can easily ignite.
Fitting the dust extraction adapter (see figure B)
Fasten the dust extraction adapter (29) to the
base plate (7) using the fastening screw (28).
A dust extraction hose with a diameter of 19 mm
can be connected to the dust extraction adapter
(29).
The dust extraction adapter must only be fit-
u
ted if an external dust extraction system is
connected. Otherwise the extraction duct can
become clogged.
No dust bags should be connected to the
u
dust extraction adapter. Otherwise the extrac-
English
tion system can become clogged.
To ensure optimum extraction, the dust extraction
adapter (29) must be cleaned regularly.
External dust extraction
Connect the dust extraction hose (30) to a dust
extractor (accessory).
The dust extractor must be suitable for the mater-
ial being worked.
When extracting dry dust that is especially detri-
mental to health or carcinogenic, use a special
dust extractor.
