Operation
Operating Modes
 Before any work on the power tool, remove the battery.
Adjusting the Cutting Depth (see figure B)
 Adjust the cutting depth to the thickness of the work-
piece. Less than a full tooth of the blade teeth should be
visible below the workpiece.
Loosen the clamping lever 10. For a smaller cutting depth,
pull the saw away from the base plate 13; for a larger cutting
depth, push the saw toward the base plate 13. Adjust the de-
sired cutting depth at the cutting-depth scale. Tighten the
clamping lever 10 again.
The tightening tension of the clamping lever 10 can be read-
justed. For this, unscrew the clamping lever 10, and screw it
back again turned offset by at least 30° in anticlockwise direc-
tion.
Cutting Marks
0°
The cutting mark 12 indicates the position of the saw blade
for straight cuts.
For precise cuts, position the circular saw against the work-
piece as shown in the figure. It is best to carry out a trial cut.
Utility Hook (see figure C)
Your tool is equipped with a utility hook 3 for hanging it, e. g.,
to a ladder, etc. Simply fold out the utility hook 3 to the re-
quired position.
 When the tool is hanging by the utility hook, ensure
that the saw blade is protected against unintended
contact. Danger of injury.
Fold the utility hook 3 back in again when you are ready to
continue working.
Starting Operation
Inserting the battery
 Use only original Bosch lithium-ion batteries with the
voltage listed on the nameplate of your power tool.
Using other batteries can lead to injuries and pose a fire
hazard.
Insert the charged battery 9 into the base of the power tool
until the battery is securely locked.
Switching On and Off
To start the machine, first push the lock-off button for the
On/Off switch 6 and then press the On/Off switch 7 and keep
it pressed.
To switch off the machine, release the On/Off switch 7.
1 609 92A 0PX | (18.11.14)
Note: For safety reasons, the On/Off switch 7 cannot be
locked; it must remain pressed during the entire operation.
To save energy, only switch the power tool on when using it.
Run-on Brake
An integrated run-on brake reduces the run-on period of the
saw blade after switching off the machine.
Protection Against Deep Discharging
The lithium-ion battery is protected against deep discharging
by the "Electronic Cell Protection (ECP)". When the battery is
empty, the machine is switched off by means of a protective
circuit: The inserted tool no longer rotates.
Working Advice
Protect saw blades against impact and shock.
Guide the machine evenly and with light feed in the cutting di-
rection. Excessive feed significantly reduces the service life of
the saw blade and can cause damage to the power tool.
Sawing performance and cutting quality depend essentially
on the condition and the tooth form of the saw blade. There-
fore, use only sharp saw blades that are suited for the material
to be worked.
Sawing with Parallel Guide (see figure D)
0°
The parallel guide 14 enables exact cuts along a workpiece
edge and cutting strips of the same dimension.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a board or
strip can be clamped to the workpiece as an auxiliary guide;
the base plate of the circular saw can be guided alongside the
auxiliary guide.
Recommendations for Optimal Handling of the Battery
Protect the battery against moisture and water.
Store the battery only within a temperature range between
–20 °C and 50 °C. As an example, do not leave the battery in
the car in summer.
Occasionally clean the venting slots of the battery using a soft,
clean and dry brush.
A significantly reduced working period after charging indi-
cates that the battery is used and must be replaced.
Observe the notes for disposal.

Maintenance and Service

Maintenance and Cleaning

 Before any work on the machine itself (e. g. mainte-
nance, tool change, etc.) as well as during transport
and storage, remove the battery from the power tool.
There is danger of injury when unintentionally actuating
the On/Off switch.
 For safe and proper working, always keep the machine
and ventilation slots clean.
The retracting blade guard must always be able to move freely
and retract automatically. Therefore, always keep the area
around the retracting blade guard clean. Remove dust and
chips by blowing out with compressed air or with a brush.
