Cutting Marks
0° 45°
The 0° cutting mark (9) indicates the position of
the saw blade for right-angled cuts. The 45° cut-
ting mark (10) indicates 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 trial cut.
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 3 from the front into
the base of the power tool. Push the battery com-
pletely 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 power tool, 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 switch off the power tool, release the On/Off
switch 2.
Note: For safety reasons, the On/Off switch 2
cannot be locked on but must remain pressed
during operation.
Run-on Brake
An integrated run-on brake reduces the run-on
period of the saw blade after switching off the
machine.
Bosch Power Tools
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:
0° 45°
The inserted tool no longer rotates.
Working Instructions
Protect saw blades against impact and shock.
Guide the power tool evenly and with moderate
feed in the cutting direction. A high feed rate sig-
nificantly reduces the service life of the cutting
tools and can damage the machine.
Sawing performance and cutting quality depend
essentially on the condition and the tooth form of
the saw blade. Therefore, 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 extrac-
tion.
Sawing with Parallel Guide (see figure D)
The parallel guide 8 enables exact cuts along a
workpiece edge and cutting strips of the same di-
mension.
Sawing with Auxiliary Guide (see figure E)
For sawing large workpieces or straight edges, a
board or strip can clamped to the workpiece as
an auxiliary guide; the base plate of the circular
saw can be guided alongside the auxiliary guide.
Sawing with Guide Rail (see figure F)
The guide rail 30 is used to carry out straight
cuts.
Note: Use the guide rail 30 only for right-angled
cuts. When using for miter cuts, the guide rail 30
can become damaged.
