Note: For bevel cuts, the cutting depth is small-
er than the setting indicated on the cutting-
depth scale 15.
Cutting Marks
45 0
The 0° cutting mark (9) indicates the position of
the saw blade for right-angled cuts. The 45° cut-
ting mark (8) 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
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
Switching On and Off
To start the machine, first push the lock-off but-
ton for the On/Off switch 2 and then press the
On/Off switch 1 and keep it pressed.
To switch off the machine, release the On/Off
switch 1.
Note: For safety reasons, the On/Off switch 1
cannot be locked; it must remain pressed during
the entire operation.
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.
Bosch Power Tools
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
45 0
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 10 enables exact cuts along a
workpiece edge and cutting strips of the same
dimension.
Loosen wing bolt 7 and slide the scale of the
parallel guide 10 through the guide in the base
plate 13. Adjust the desired cutting width as the
scale setting at the respective cutting mark 9 or
8; see Section "Cutting Marks". Tighten wing
bolt 7 again.
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 27 is used to carry out straight
cuts.
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.
The rubber lip on the guide rail acts as a splinter
guard that prevents fraying or tearing out of the
surface when sawing wooden materials. For
this, the teeth of the saw blade must face direct-
ly against the rubber lip.
The guide rail 27 must not extend beyond the
face side of the workpiece where the cut is to
be started.
