External Dust Extraction
Connect the vacuum hose 30 to a vacuum clean-
er (accessory). An overview for connecting to
various vacuum cleaners can be found at the
end of this manual.
The machine can be plugged directly into the re-
ceptacle of a Bosch all-purpose vacuum cleaner
with remote starting control. The vacuum clean-
er starts automatically when the machine is
switched on.
The vacuum cleaner must be suitable for the ma-
terial being worked.
When vacuuming dry dust that is especially det-
rimental to health or carcinogenic, use a special
vacuum cleaner.
Operation

Operating Modes

Before any work on the machine itself, pull
the mains plug.
Adjusting the Cutting Depth (see figure C)
Adjust the cutting depth to the thickness of
the workpiece. Less than a full tooth of the
blade teeth should be visible below the work-
piece.
Loosen the clamping lever 23 . For a smaller cut-
ting depth, pull the saw away from the base
plate 12 ; for a larger cutting depth, push the
saw toward the base plate 12 . Adjust the de-
sired cutting depth at the cutting-depth scale.
Tighten the clamping lever 23 again.
If the cutting depth cannot be fully adjusted af-
ter loosening clamping lever 23 , pull clamping
lever 23 away from the saw and swivel it down-
ward. Release the clamping lever 23 again. Re-
peat this procedure until the requested cutting
depth can be adjusted.

If the cutting depth cannot be sufficiently
locked after tightening clamping lever 23 , pull
clamping lever 23 away from the saw and swivel
it upward. Release the clamping lever 23 again.
Repeat this procedure until the cutting depth is
locked.
Adjusting the Cutting Angle
Loosen the wing bolts 6 and 25 . Tilt the saw
sidewards. Adjust the desired measure on the
scale 5 . Tighten the wing bolts 6 and 25 again.
Note: For bevel cuts, the cutting depth is small-
er than the setting indicated on the cutting-
depth scale 24 .
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 .
