– Swing the retracting blade guard (11) back and hold on
to it firmly.
– Place the saw blade (12) on the mounting flange (26).
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 (11).
– Attach the clamping flange (25) and screw in the clamp-
ing bolt in rotational direction ➋. Ensure that the mount-
ing flange (26) and clamping flange (25) are installed in
the correct position.
– Press and hold the spindle lock button (22).
– Use the hex key (23) to tighten the clamping bolt in rota-
tional direction ➋. The tightening torque should be
6−9 Nm, which corresponds to hand-tight plus ¼ turn.
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 D)
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.
The cutting depth can be set using the lever for cutting depth
preselection (29).
For a smaller cutting depth, pull the saw away from the base
plate (13); for a larger cutting depth, push the saw towards
the base plate (13). Set the required cutting depth on the
scale (28).
Adjusting the Mitre/Bevel Angle
We recommend that you place the power tool down on the
front side of the protective guard (15).
Loosen the wing bolt (7). Swivel the saw to the side. Set the
required mitre angle on the scale (6). Retighten the wing
bolt (7).
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (28).
Cut marks (see figure E)
The "CutControl" viewing window (9), which folds out to the
front, allows the circular saw to be guided precisely along
the cutting line that is applied to the workpiece. The "Cut-
Control" viewing window (9) has markings for right-angled
cuts and 45° cuts.
The 0° cut mark (30) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (31) indic-
ates the position of the saw blade when making a 45° cut.
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

Switching on/off

To start the power tool, first press the lock-off switch (4),
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.
Run-out brake
An integrated run-out brake shortens the time the saw blade
keeps running for after the power tool has been switched
off.
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 in order to achieve a high cut quality. Applying too
much pressure will significantly reduce the service life of ap-
plication 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.
