Battery charge indicator
The green LEDs on the battery charge indicator indicate the
state of charge of the battery. For safety reasons, it is only
possible to check the state of charge when the power tool is
not in operation.
Press the button for the battery charge indicator or
show the state of charge. This is also possible when the bat-
tery is removed.
If no LED lights up after pressing the button for the battery
charge indicator, then the battery is defective and must be
replaced.

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.
Fitting
Only use saw blades the maximum permitted speed of
u
which is higher than the no-load speed of the power
tool.

Inserting/changing the circular saw blade
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
to
from unintentionally pressing the on/off switch.
Wear protective gloves when fitting the saw blade.
u
Danger of injury when touching the saw blade.
Do not use abrasive wheels as the application tool un-
u
der any circumstances.
Only use saw blades that match the specifications
u
given in this operating manual and that are tested and
marked in accordance with EN 847-1

– Press and hold the spindle lock button (4).
Do not press the spindle lock button (4) while the saw
u
spindle is moving. The power tool may become damaged
if this happens.
– Use the hex key (27) to undo the clamping bolt (26) in ro-
tational direction ➊.

– Swing the retracting blade guard (14) back and hold on
to it firmly.
80–100 %
– Remove the clamping flange (25) and the saw blade (24)
60–80 %
from the saw spindle (22).
40–60 %
Fitting the saw blade (see figure A)
20–40 %
To change tools, we recommend that you place the power
5–20 %
tool down on the front side of the motor housing.
0–5 %
– Clean the saw blade (24) and all the clamping elements
to be fitted.
– Swing the retracting blade guard (14) back and hold on
to it firmly.
– Place the saw blade (24) on the mounting flange (23).
The cutting direction of the teeth (direction of the arrow
on the saw blade) must match the rotational direction of
the arrow on the retracting blade guard (14).
– Attach the clamping flange (25) and screw in the clamp-
ing bolt (26) in rotational direction ➋. Ensure that the
mounting flange (23) and clamping flange (25) are in-
stalled in the correct position.
– Press and hold the spindle lock button (4).
– Use the hex key (27) to tighten the clamping bolt (26) in
