Switching on/off
Make sure that you are able to press the On/Off switch
u
without releasing the handle.
To start the power tool, first press the lock-off switch (6),
then press and hold the on/off switch (7).
To switch off the power tool, release the on/off switch (7).
Note: For safety reasons, the on/off switch (7) 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.
Switching on the LED worklight
The lamp (26) lights up when the on/off switch (7) is lightly
or fully pressed, meaning that the work area is illuminated in
poor lighting conditions.

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 with the parallel guide (see figure D)
The parallel guide (14) allows you to make precise cuts
along the edge of a workpiece and cut strips with the same
dimensions.
Sawing with an auxiliary guide (see figure E)
For working on large workpieces or for cutting straight
edges, you can securely fasten a board or rail to the work-
piece as an auxiliary guide. The circular saw can be guided
along the path of this auxiliary guide with the base plate.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of −20 to
50 °C. Do not leave the battery in your car in the summer, for
example.

Occasionally clean the ventilation slots on the battery using a
soft brush that is clean and dry.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.

Maintenance and Service

Maintenance and Cleaning

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.
To ensure safe and efficient operation, always keep
u
the power tool and the ventilation slots clean.
Replace the lid on the chip container (24) in case of
u
damage.
The retracting blade guard must always be able to move
freely and retract automatically. It is therefore important to
keep the area around the retracting blade guard clean at all
times. Remove dust and chips with a paintbrush.
