– Press the spindle lock button 19 and keep it pressed.
– With the Allen key 24, tighten the clamping bolt 23 turning
in rotation direction . The tightening torque is between
6–9 Nm, which corresponds to hand tight plus ¼ turn.
Operation

Operating Modes

 Before any work on the power tool, remove the battery.
Adjusting the Cutting Depth (see figure D)
 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 wing bolt 25. For a smaller cutting depth, pull the
machine from the base plate 7; for a larger cutting depth,
push the machine toward the base plate 7. Adjust the de-
sired cutting depth at the cutting-depth scale 26. Tighten
wing bolt 25 again.
Adjusting the Cutting Angle
– It is best to place the machine on the face side of the blade
guard 5.
– Loosen wing bolt 13. Tilt the saw sidewards. Adjust the de-
sired setting at the scale 14. Tighten wing bolt 13 again.
Note: For bevel cuts, the cutting depth is smaller than the set-
ting indicated on the cutting-depth scale 26.
Cutting Marks (see figure E)
The "CutControl" 12 viewing window, which folds out to the
front, is used for precise guiding of the circular saw alongside
the cutting line on the workpiece. The "CutControl" 12 view-
ing window has a mark each for right-angled cuts and for 45°
cuts.
The 0° cutting mark (27) indicates the position of the saw
blade for right-angled cuts. The 45° cutting mark (28) indi-
cates the position of the saw blade for 45° cuts.
– For precise cuts, position the circular saw against the
workpiece as shown in the figure. It is best to carry out a tri-
al cut.

Starting Operation

Inserting the battery
 Use only original Bosch lithium ion batteries with the
voltage listed on the nameplate of your power tool. Us-
ing other batteries can lead to injuries and pose a fire haz-
ard.

– Insert the charged battery 3 from the front into the base of
the power tool. Push the battery completely into the base
until the red stripe can no longer be seen and the battery is
securely locked.
Switching On and Off
– To start the machine, first push the lock-off button for the
On/Off switch 1 and then press the On/Off switch 2 and
keep it pressed.
To save energy, only switch the power tool on when using
it.
– To switch off the machine, 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-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 Wood
The correct selection of the saw blade depends on the type
and quality of the wood and whether lengthway or crossway
cuts are required.
When cutting spruce lengthways, long spiral chips are
formed.
Beech and oak dusts are especially detrimental to health.
Therefore, work only with dust extraction.
Sawing Non-ferrous Metals
Note: Use only a sharp saw blade that is suitable for non-fer-
rous metals. This ensures a clean cut and prevents blade bind-
ing.
Guide the switched on power tool against the workpiece and
carefully start the cut. Continue the cut with low feed and
without interruption.
When sawing profiles, always begin the cut from the narrow
side; when sawing U-profiles, never start the cut from the
open side. Support long profiles in order to avoid blade bind-
ing and kickback of the power tool.
