Bosch Power Tools
Cutting Marks
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
f
Use only original Bosch lithium ion batter-
ies 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
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 but-
ton for the On/Off switch
1
and
then
press the
On/Off switch
2
and keep it pressed.
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 Protec-
tion (ECP)”. When the battery is empty, the ma-
chine 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 direction. Excessive feed significant-
ly 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. 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
dimension.
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 G)
The guide rail
33
is used to carry out straight
cuts.
Note:
Use the guide rail
33
only for right-angled
cuts. When using for mitre cuts, the guide rail
33
can become damaged.
