Starting Operation

Inserting the Battery
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 Li-ion battery is protected against deep dis-
charging 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 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 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 mitre cuts, the guide rail 30
can become damaged.
The adhesive coating prevents the guide rail
from slipping and protects the surface of the
workpiece. The coating of the guide rail allows
the circular saw to glide easily.
Place the circular saw directly onto the guide
rail 30. Fasten the guide rail 30 with suitable
clamping devices, e. g., screw clamps, on the
workpiece in such a manner that the narrow leg
of the guide rail 30 faces toward the saw blade.
The guide rail 30 must not extend beyond the
face side of the workpiece where the cut is to
be started.
Switch the machine on and guide it in the cut-
ting direction applying moderate and steady
feed.
Two guide rails can be connected to one with
use of the connection piece 31. Clamping is car-
ried out with the four screws located in the con-
nection piece.
