– 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.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.
Fitting the dust extraction adapter (see figure B)
Fasten the dust extraction adapter (26) to the base plate (6)
using the fastening screw (25).
A dust extraction hose with a diameter of 35 mm can be con-
nected to the dust extraction adapter (26).
The dust extraction adapter must only be fitted if an
u
external dust extraction system is connected. Other-
wise the extraction duct can become clogged.
No dust bags should be connected to the dust extrac-
u
tion adapter. Otherwise the extraction system can be-
come clogged.
To ensure optimum extraction, the dust extraction adapter
(26) must be cleaned regularly.
External dust extraction
Connect the dust extraction hose (27) to a dust extractor
(accessory). You will find an overview of how to connect to
various dust extractors at the end of these operating instruc-
tions.
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.
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 (29). For a smaller cutting depth,
pull the saw away from the base plate (6); for a larger cutting
depth, push the saw towards the base plate (6). Adjust the
desired cutting depth at the cutting-depth scale. Retighten
the clamping lever (29).
The clamping force of the clamping lever (29) can be read-
justed. To do so, unscrew the clamping lever (29) and
retighten it in a position offset by at least 30° in an anticlock-
wise direction.
Adjusting the Mitre/Bevel Angle
We recommend that you place the power tool down on the
front side of the protective guard (4).
1 609 92A 7T1 | (25.05.2022)
Loosen the wing bolt (11). Swivel the saw to the side. Set
the required mitre angle on the scale (13). Retighten the
wing bolt (11).
Note: When making mitre cuts, the cutting depth is less than
the value shown on the cutting depth scale (28).
Cut marks
0° 45°
The 0° cut mark (9) indicates the position of the saw blade
when making a right-angled cut. The 45° cut mark (10) 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
Inserting the battery
Use only original Bosch lithium-ion batteries with the
u
voltage stated on the type plate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Slide the charged battery (3) into the foot of the power tool
from the front. Press the battery fully into the foot until the
red stripe is no longer visible and 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.
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
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
0° 45°
