External dust extraction
Connect the extraction hose (30) to a dust extractor (ac-
cessory). You will find an overview of connecting to various
dust extractors at the end of these operating instructions.
The dust extractor must be suitable for the material being
worked.
When extracting dry dust that is especially detrimental to
health or carcinogenic, use a special dust extractor.
Mounting the utility hook (see figures F–G)
Press the cover of the utility hook (21) on both sides and re-
move it. Mount the utility hook (32) and secure it with two
screws. Tighten the screws with a torque of 1.8 − 2 Nm. The
utility hook (32) can be swivelled.
Operation
Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.

Operating modes

Setting the cutting depth (see figure C)
Adapt the cutting depth to the thickness of the work-
u
piece. A space of less than the height of one full tooth
should be visible under the workpiece.
Loosen the clamping lever (19). For a smaller cutting depth,
pull the saw away from the base plate (8); for a larger cutting
depth, push the saw towards the base plate (8). Adjust the
desired cutting depth at the cutting-depth scale. Retighten
the clamping lever (19).
Adjusting the mitre/bevel angle
We recommend that you place the power tool down on the
front side of the protective guard (6).
Loosen the adjusting lever for mitre/bevel angle
preselection (17). Swivel the saw to the side. Set the re-
quired mitre/bevel angle on the scale (14). Screw the ad-
justing lever (17) back on again.
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (5).
Cut Marks
0 45
The 0° cut mark (12) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (13) indic-
ates the position of the saw blade when making a 45° cut.
1 609 92A 7TB | (18.05.2022)
For a precise cut, place the circular saw against the work-
piece as shown in the figure. We recommend making a test
cut.
Start-up
Inserting the battery
Push the charged battery (3) into the power tool until the
battery is securely locked.
Switching on/off
To start the power tool, first press the lock-off switch (1),
then press and hold the on/off switch (2).
To switch off the power tool, release the on/off switch (2).
Note: For safety reasons, the on/off switch (2) cannot be
locked; it must remain pressed during the entire operation.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharge
by the Electronic Cell Protection (ECP). When the battery is
discharged, the power tool is switched off by means of a pro-
tective circuit: The application tool no longer rotates.

Practical advice

Remove the battery from the power tool before carry-
u
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage. There is risk of injury
from unintentionally pressing the on/off switch.
The width of cut varies depending on the saw blade used.
Protect saw blades against shock and impact.
Guide the power tool evenly, pushing it gently in the cutting
direction. Applying too much pressure to the power tool
when moving it in the cutting direction significantly reduces
the service life of the application tools and can damage the
power tool.
The sawing performance and the quality of the cut essen-
tially depend on the condition and the tooth shape of the
saw blade. This is why you should only use sharp saw blades
that are suitable for the material being machined.
Sawing wood
Choosing the right saw blade depends on the wood type,
wood quality and whether cuts with or against the grain are
required.
Making cuts in spruce with the grain produces long, spiral-
shaped chips.
Beech and oak dust is especially detrimental to health.
Therefore, work only with dust extraction.
Sawing with a parallel guide (see figure D)
0 45
The parallel guide (10) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Slide the guide rod of the parallel guide (10) through the
guide into the base plate (8). Mount the parallel guide (10)
with the wing bolt (15).
